(1219 mm) clearance required on top of unit. Setting the Unit CAUTION In order to avoid injury, take proper precaution when lifting heavy objects. Outdoor units operate under a wide range of weather conditions; therefore, several factors must be considered when positioning the outdoor unit. Position the unit to allow adequate airflow and servicing clearance. Maintain a minimum clearance of 24 inches (610 mm) between multiple units as illustrated in figure 1 for installation clearances. 1. Place a sound-absorbing material, such as Isomode, under the unit if it will be installed in a location or position that will transmit sound or vibration to the living area or adjacent buildings. 2. Install the unit high enough above ground or roof to allow adequate drainage of defrost water and prevent ice build-up. 3. In heavy snow areas, do not locate unit the where snowdrifts will likely build. The unit base should be elevated above the depth of average snows. NOTE - Elevation of the unit may be accomplished by constructing a frame using suitable materials. If a support frame is constructed, it must not block drain holes in unit base. Page 3 Figure 1. Installation Clearances SLAB MOUNTING When installing unit at grade level, the top of the slab should be high enough above grade so that water from higher ground will not collect around the unit. The slab should have a slope tolerance away from the building of 2 degrees or 2 inches per 5 feet (50 mm per 1500 mm) to prevent ice build-up under the unit during a defrost cycle. NOTE If necessary for stability, anchor unit to slab as described in Stabilizing Unit on Uneven Surfaces on page 4.

ELEVATING THE UNIT (SMALL BASE UNITS) If additional elevation is necessary, raise the unit by extending the length of the unit support feet. This may be done by cutting four equal true cut lengths of Schedule (SCH) 40, 4" (101.6mm) piping to the height required as illustrated in figure 3. NOTE Keep the height of extenders short enough to ensure a sturdy installation. If it is necessary to extend further, consider a different type of field fabricated framework that is sturdy enough for greater heights. The inside diameter of the 4" (101.6mm) piping is approximately 0.25" (6.35mm) greater than the pre installed feet on the unit. Devise a shim that will take up the space and hold the extenders onto the feet during this procedure. Small strips of 0.125" (3.175mm) thick adhesive foam may be used. One or two small 1" (25.4mm) square strips should be adequate to hold the extender in place. Base NOTE Keep the height of extenders short enough to ensure a sturdy installation. If it is necessary to extend further, consider a different type of field fabricated framework that is sturdy enough for greater heights.

Refrigerant Piping The Clean Air Act of 1990 bans the intentional venting of refrigerant (CFC s, HFC s, and HCFC s) as of July 1, 1992. Approved methods of recovery, recycling or reclaiming must be followed. Fines and/or incarceration may be levied for noncompliance. If the XP14 unit is being installed with a new indoor coil and line set, the plumbing connections should be made as outlined in this section. If an existing line set and/or indoor coil is going to be used to complete the XP14 system, refer to the following section that includes flushing procedures. Field refrigerant piping consists of liquid and vapor lines from the outdoor unit (sweat connections) to the indoor coil (flare or sweat connections). Use Lennox L15 (sweat, non-flare) series line sets as shown in table 3 or use field-fabricated refrigerant lines. Refer to Refrigerant Piping Guide (Corp. 9351 L9) for proper size, type, and application of field fabricated lines. Valve sizes are also listed in table 3. REFRIGERANT LINE CONNECTIONS XP14 OUTDOOR UNIT MATCHED WITH NEW INDOOR COIL AND LINE SET If replacing an existing coil equipped with a liquid line functioning as a metering orifice, replace the liquid line prior to installing the XP14 unit.

In addition, be sure to consider the following points: Select line set diameters from table 3 to ensure that oil returns to the compressor. Units are designed for line sets of up to 50 feet (15 m); for longer line sets, consult piping guidelines. Size vertical vapor riser to maintain minimum velocity at minimum capacity. INSTALLING REFRIGERANT LINE Pay close attention to line set isolation during installation of any heat pump or a/c system. When properly isolated from building structures (walls, ceilings. floors), the refrigerant lines will not create unnecessary vibration and subsequent noises. Also, consider the following when placing and installing a high efficiency outdoor unit: 1. PlacementSome localities are adopting sound ordinances based on the unit s noise level observed from the adjacent property, not from the installation property. Install the unit as far as possible from the property line. When possible, do not install the unit directly outside a window. Glass has a very high level of sound transmission. Figure 14 shows how to place the outdoor unit and line set. Install unit away from windows Two 90 elbows installed in line set will reduce line set vibration. Figure 14. Outside Unit Placement 2. Line Set IsolationThe following illustrations demonstrate procedures which ensure proper refrigerant line set isolation. Figure 15 on page 9 shows how to install line sets on horizontal runs. Figure 16 on page 9 shows how to install line sets on vertical runs. Figure 17 on page 9 shows how to make a transition from horizontal to vertical 505244M 10/09 Page 8

Refrigerant Line Sets: Transition from Vertical to Horizontal BRAZING CONNECTION PROCEDURE WARNING Polyol ester (POE) oils used with HFC 410A refrigerant absorb moisture very quickly. It is very important that the refrigerant system be kept closed as much as possible. DO NOT remove line set caps or service valve stub caps until you are ready to make connections. 1. Cut ends of the refrigerant lines square (free from nicks or dents). Debur the ends. The pipe must remain round; do not pinch end of the line. 2. Flow dry nitrogen through the refrigerant piping while making line set connections; this prevents carbon deposits (oxidation) buildup on the inside of the joints being brazed. Such buildup may restrict refrigerant flow through screens and metering devices. To do this: Flow regulated nitrogen (at 1 to 2 psig) through the refrigeration gauge set into the Schrader port connection on the vapor service valve and out of the Schrader port connection on the liquid service valve. (Metering device (CTXV and RFC) will allow low pressure nitrogen to flow through the system.) Page 9 XP14 SERIES

While nitrogen is flowing, braze refrigerant line set to the indoor and outdoor units. : The flow of nitrogen must have an escape path other than through the joint to be brazed. 3. Use silver alloy brazing rods (5 or 6 percent minimum silver alloy for copper to copper brazing or 45 percent silver alloy for copper to brass or copper to steel brazing) which are rated for use with HFC 410A refrigerant. 4. Wrap a wet cloth around the valve body and the copper tube stub to protect it from heat damage during brazing. Wrap another wet cloth underneath the valve body to protect the base paint. NOTE The tube end must stay bottomed in the fitting during final assembly to ensure proper seating, sealing and rigidity. 5. Install a field provided check expansion valve (approved for use with HFC 410A refrigerant) in the liquid line at the indoor coil. Flushing Existing Line Set and Indoor Coil If this unit is being matched with an approved line set or indoor coil which was previously charged with HCFC 22 refrigerant, or if it is being matched with a coil which was manufactured before January of 1999, the coil and line set must be flushed prior to installation. Take care to empty all existing traps. Polyol ester (POE) oils are used in Lennox units charged with HFC 410A refrigerant. Residual mineral oil can act as an insulator, preventing proper heat transfer. It can also clog the check expansion valve, reducing system performance and capacity. Failure to properly flush the system per the instructions below will void the warranty. WARNING Danger of fire. Bleeding the refrigerant charge from only the high side may result in the low side shell and suction tubing being pressurized. Application of a brazing torch while pressurized may result in ignition of the refrigerant and oil mixture check the high and low pressures before unbrazing. CAUTION This procedure should not be performed on systems which contain contaminants (Example: compressor burn out). The line set and indoor coil must be flushed with at least the same amount of clean refrigerant that previously charged the system. Check the charge in the flushing cylinder before proceeding. EQUIPMENT REQUIRED FOR FLUSHING LINE SET The following equipment is required to flush the existing line set and indoor coil: two clean HCFC 22 recovery cylinders oilless recovery machine with a pump down feature gauge set for HCFC 22 refrigerant gauge set for HFC 410A refrigerant (see Manifold Gauge Set section on page 12). FLUSHING PROCEDURE 1. Remove existing HCFC 22 refrigerant using the following, applicable procedure as illustrated in figure 18: If the existing outdoor unit is not equipped with shut off valves, or if the unit is not operational AND you plan to use the existing HCFC 22 refrigerant to flush the system Disconnect all power to the existing outdoor unit. Connect to the existing unit, a clean recovery cylinder and the recovery machine according to the instructions provided with the recovery machine. Remove all HCFC 22 refrigerant from the existing system. Check gauges after shutdown to confirm that the entire system is completely void of refrigerant. Disconnect the liquid and vapor lines from the existing outdoor unit. If the existing outdoor unit is equipped with manual shut off valves AND you plan to use NEW HCFC 22 refrigerant to flush the system Start the existing HCFC 22 system in the cooling mode and close the liquid line valve. Pump all of the existing HCFC 22 refrigerant back into the outdoor unit. (It may be necessary to bypass the low pressure switches to ensure complete refrigerant evacuation.) When the low side system pressures reach 0 psig, close the vapor line valve. Disconnect all power to the existing outdoor unit. Check gauges after shutdown to confirm that the valves are not allowing refrigerant to flow back into the low side of the system. Disconnect the liquid and vapor lines from the existing outdoor unit. 2. Remove the existing outdoor unit. Set the new HFC 410A unit and follow the Brazing Connection Procedure provided on page 9 to make line set connections. DO NOT install HFC 410A check/expansion valve at this time. 3. Make low voltage and line voltage connections to the new outdoor unit. DO NOT turn on power to the unit or open the outdoor unit service valves at this time. 505244M 10/09 Page 10

Flushing Connections 4. Remove the existing HCFC 22 refrigerant flow control orifice or check expansion valve before continuing with flushing procedures. HCFC 22 flow control devices (fixed orifice/check expansion valve) are not approved for use with HFC 410A refrigerant and may prevent proper flushing. Use a field provided fitting to reconnect the lines. 5. Remove the pressure tap valve cores from the XP14 unit s service valves. Connect an HCFC 22 cylinder with clean refrigerant to the vapor service valve. Connect the HCFC 22 gauge set to the liquid line valve and connect a recovery machine with an empty recovery tank to the gauge set. 6. Set the recovery machine for liquid recovery and start the recovery machine. Open the gauge set valves to allow the recovery machine to pull a vacuum on the existing system line set and indoor coil. 7. Invert the cylinder of clean HCFC 22 and open its valve to allow liquid refrigerant to flow into the system through the vapor line valve. Allow the refrigerant to pass from the cylinder and through the line set and the indoor coil before it enters the recovery machine. 8. After all of the liquid refrigerant has been recovered, switch the recovery machine to vapor recovery so that all of the HCFC 22 vapor is recovered. Allow the recovery machine to pull a vacuum on the system. NOTE A single system flush should remove all of the mineral oil from the existing refrigerant lines and indoor coil. A second flushing may be done (using clean refrigerant) if insufficient amounts of mineral oil were removed during the first flush. After each system flush, allow the recovery machine to pull a vacuum on the system at the end of the procedure. 9. Close the valve on the inverted HCFC 22 drum and the gauge set valves. Pump the remaining refrigerant out of the recovery machine and turn the machine off. 10. Use dry nitrogen to break the vacuum on the refrigerant lines and indoor coil before removing the recovery machine, gauges and HCFC 22 refrigerant drum. Reinstall pressure tap valve cores into XP14 unit s service valves. 11. Install check expansion valve (approved for use with HFC 410A refrigerant) in the liquid line at the indoor coil. Refrigerant Metering Device XP14 units may be used in check thermal expansion valve (CTXV) systems only. See indoor coil installation instructions and the Lennox engineering handbook for approved HFC 410A valve match ups and application information. NOTE HFC 410A systems will not operate properly with an HCFC 22 valve. Check thermal expansion valves equipped with fittings are available from Lennox. Refer to the Engineering Handbook for applicable expansion valves for use with specific match-ups.

If you install a check thermal expansion valve with an indoor coil that includes a fixed orifice, remove the orifice before the check expansion valve is installed. See figure 19 for installation of the check expansion valve. Manifold Gauge Set Manifold gauge sets used with systems charged with HFC 410A refrigerant must be capable of handling the higher system operating pressures. The gauges should be rated for use with pressures of 0 800 on the high side and a low side of 30" vacuum to 250 psi with dampened speed to 500 psi. Gauge hoses must be rated for use at up to 800 psi of pressure with a 4000 psi burst rating. Service Valves The service valves and gauge ports are used for leak testing, evacuating, charging and checking charge. Each valve is equipped with a service port which has a factory installed Schrader valve. A service port cap protects the Schrader valve from contamination and serves as the primary leak seal. To Access Schrader Port: 1. Remove service port cap with an adjustable wrench. 2. Connect gauge to the service port. 3. When testing is completed, replace service port cap. Tighten finger tight, then torque per table 1 on page 3. To Open Front-Seated Service Valves: 1. Remove stem cap with an adjustable wrench. 2. Use a service wrench with a hex head extension (3/16" for liquid-line valve sizes; 5/16" for vapor-line valve sizes) to back the stem out counterclockwise as far as it will go. 3. Replace the stem cap. Tighten finger tight, then torque per table 1 on page 3. To Close Front-Seated Service Valves: 1. Remove the stem cap with an adjustable wrench. 2. Use a service wrench with a hex head extension (3/16" for liquid-line valve sizes; 5/16" for vapor-line valve sizes) to turn the stem clockwise to seat the valve. Tighten it firmly. 3. Replace the stem cap. Tighten finger tight, then torque per table 1 on page 3.

WARNING Refrigerant can be harmful if it is inhaled. Refrigerant must be used and recovered responsibly. WARNING Fire, Explosion and Personal Safety Hazard. Failure to follow this warning could result in damage, personal injury or death. Never use oxygen to pressurize or purge refrigeration lines. Oxygen, when exposed to a spark or open flame, can cause damage by fire and/ or an explosion, that could result in personal injury or death. WARNING Danger of explosion! When using a high pressure gas such as dry nitrogen to pressurize a refrigeration or air conditioning system, use a regulator that can control the pressure down to 1 or 2 psig (6.9 to 13.8 kpa). USING AN ELECTRONIC LEAK DETECTOR Leak detector must be capable of sensing HFC refrigerant. 1. Connect a cylinder of HFC 410A to the center port of the manifold gauge set. 2. With both manifold valves closed, connect the cylinder of HFC 410A refrigerant. Open the valve on the HFC 410A cylinder (vapor only). 3. Open the high pressure side of the manifold to allow HFC 410A into the line set and indoor unit. Weigh in a trace amount of HFC 410A. [A trace amount is a maximum of 2 ounces (57 g) refrigerant or 3 pounds (31 kpa) pressure]. Close the valve on the HFC 410A cylinder and the valve on the high pressure side of the manifold gauge set. Disconnect HFC 410A cylinder. 4. Connect a cylinder of dry nitrogen with a pressure regulating valve to the center port of the manifold gauge set. 5. Connect the manifold gauge set high pressure hose to the vapor valve service port. (Normally, the high pressure hose is connected to the liquid line port; however, connecting it to the vapor port better protects the manifold gauge set from high pressure damage.) 6. Adjust dry nitrogen pressure to 150 psig (1034 kpa). Open the valve on the high side of the manifold gauge set in order to pressurize the line set and the indoor unit. 7. After a few minutes, open a refrigerant port to ensure the refrigerant you added is adequate to be detected. (Amounts of refrigerant will vary with line lengths.) Check all joints for leaks. Purge dry nitrogen and HFC 410A mixture. Correct any leaks and recheck. Evacuation Evacuating the system of noncondensables is critical for proper operation of the unit. Noncondensables are defined as any gas that will not condense under temperatures and pressures present during operation of an air conditioning system. Noncondensables and water vapor combine with refrigerant to produce substances that corrode copper piping and compressor parts. Use a thermocouple or thermistor electronic vacuum gauge that is calibrated in microns. Use an instrument that reads from 50 microns to at least 23,000 microns. 1. Connect manifold gauge set to the service valve ports as follows: low pressure gauge to vapor line service valve high pressure gauge to liquid line service valve 2. Connect micron gauge. 3. Connect the vacuum pump (with vacuum gauge) to the center port of the manifold gauge set. 4. Open both manifold valves; start the vacuum pump. 5. Evacuate the line set and indoor unit to an absolute pressure of 23,000 microns (29.01 inches of mercury). During the early stages of evacuation, it is desirable to close the manifold gauge valve at least once to determine if there is a rapid rise in absolute pressure. A rapid rise in pressure indicates a relatively large leak. If this occurs, repeat the leak testing procedure. Page 13 XP14 SERIES

NOTE The term absolute pressure means the total actual pressure within a given volume or system, above the absolute zero of pressure. Absolute pressure in a vacuum is equal to atmospheric pressure minus vacuum pressure. 6. When the absolute pressure reaches 23,000 microns (29.01 inches of mercury), close the manifold gauge valves, turn off the vacuum pump and disconnect the manifold gauge center port hose from vacuum pump. Attach the manifold center port hose to a dry nitrogen cylinder with pressure regulator set to 150 psig (1034 kpa) and purge the hose. Open the manifold gauge valves to break the vacuum in the line set and indoor unit. Close the manifold gauge valves. WARNING Danger of Equipment Damage! Avoid deep vacuum operation. Do not use compressors to evacuate a system. Extremely low vacuums can cause internal arcing and compressor failure. Damage caused by deep vacuum operation will void warranty. 7. Shut off the dry nitrogen cylinder and remove the manifold gauge hose from the cylinder. Open the manifold gauge valves to release the dry nitrogen from the line set and indoor unit. 8. Reconnect the manifold gauge to the vacuum pump, turn the pump on, and continue to evacuate the line set and indoor unit until the absolute pressure does not rise above 500 microns (29.9 inches of mercury) within a 20 minute period after shutting off the vacuum pump and closing the manifold gauge valves. 9. When the absolute pressure requirement above has been met, disconnect the manifold hose from the vacuum pump and connect it to an upright cylinder of HFC 410A refrigerant. Open the manifold gauge valves to break the vacuum from 1 to 2 psig positive pressure in the line set and indoor unit. Close manifold gauge valves and shut off the HFC 410A cylinder and remove the manifold gauge set. Start Up If unit is equipped with crankcase heater, it should be energized 24 hours before unit start up to prevent compressor damage as a result of slugging. 1. Rotate fan to check for frozen bearings or binding. 2. Inspect all factory and field-installed wiring for loose connections. NOTE After the system has been evacuated and before completing all the remaining start up steps, this is the ideal time to adjust the amount of refrigerant made necessary by line set length difference and by the specific indoor unit match up. Skip to the paragraph Setup for Checking and Adding Charge" on page 15 to setup for charging and for determining if charge is needed; adjust the charge accordingly. 3. Open the liquid line and vapor line service valves (counterclockwise) to release refrigerant charge (contained in outdoor unit) into the system. 505244M 10/09 Page 14 4. Replace stem caps and secure finger tight, then tighten an additional (1/6) one-sixth of a turn. 5. Check voltage supply at the disconnect switch. The voltage must be within the range listed on the unit nameplate. If not, do not start the equipment until the power company has been consulted and the voltage condition has been corrected. 6. Set the thermostat for a cooling demand. Turn on power to indoor blower unit and close the outdoor unit disconnect to start the unit. 7. Recheck voltage while the unit is running. Power must be within range shown on the nameplate. Mineral oils are not compatible with HFC 410A. If oil must be added, it must be a polyol ester oil. Refrigerant Charge This system is charged with HFC 410A refrigerant which operates at much higher pressures than HCFC 22. The recommended check expansion valve is approved for use with HFC 410A. Do not replace it with a valve that is designed to be used with HCFC 22. This unit is NOT approved for use with coils that include metering orifices or capillary tubes. Units are factory-charged with the amount of HFC 410A refrigerant indicated on the unit rating plate. This charge is based on a matching indoor coil and outdoor coil with 15 ft. (4.6 m) line set. For varying lengths of line set, refer to table 3 for refrigerant charge adjustment. A blank space is provided on the unit rating plate to list the actual field charge. Check Indoor Airflow before Charging Check airflow before charging! NOTE Be sure that filters and indoor and outdoor coils are clean before testing. COOLING MODE INDOOR AIRFLOW CHECK Check airflow using the Delta T (DT) process (figure 23). HEATING MODE INDOOR AIRFLOW CHECK Blower airflow (CFM) may be calculated by energizing electric heat and measuring: temperature rise between the return air and supply air temperatures at the indoor coil blower unit, voltage supplied to the unit, amperage being drawn by the heat unit(s). Then, apply the measurements taken in following formula to determine CFM: CFM = Amps x Volts x 3.41 1.08 x Temperature rise (F) Check indoor airflow using the step procedures as illustrated in figure 23.

Determine if fan needs adjustmentif the difference between the measured T Drop and the desired DT (T Drop DT) is within +3º, no adjustment is needed. See examples: Assume DT = 15 and A temp. = 72º, these C temperatures would necessitate stated actions: Cº T Drop DT = ºF ACTION 53º 19 15 = 4 Increase the airflow 58º 14 15 = 1 (within +3º range) no change 62º 10 15 = 5 Decrease the airflow Step 4. Adjust the fan speedsee indoor unit instructions to increase/decrease fan speed. Changing air flow affects all temperatures; recheck temperatures to confirm that the temperature drop and DT are within +3º. Figure 23.

CALCULATING CHARGE If the system is void of refrigerant, first, locate and repair any leaks and then weigh in the refrigerant charge into the unit. To calculate the total refrigerant charge: Amount specified on nameplate Adjust amt. for variation in line set length (table 4) Additional charge specified per indoor unit match up (table 5) Total charge + + = Weigh in Charge 1. Recover the refrigerant from the unit. 2. Conduct leak check; evacuate as previously outlined. 3. Weigh in the unit nameplate charge plus any charge required for line set differences from 15 feet and any extra indoor unit match up amount per table 5. (If weighing facilities are not available, use the subcooling method.) Table 4. Charge per Line Set Lengths Liquid Line Set Diameter Oz. per 5 ft. (g per 1.5m) adjust from 15 ft. (4.6m) line set* 3/8 in. (9.5mm) 3 ounce per 5 ft. (85g per 1.5m) NOTE *If line length is greater than 15 ft. (4.6 m), add this amount. If line length is less than 15 ft. (4.6 m), subtract this amount. Subcooling Charge Requirementsthese items are required for charging: Manifold gauge set connected to unit. Thermometers for measuring outdoor ambient, liquid line, and vapor line temperatures. When to use cooling modewhen outdoor temperature is 60 F (15 C) and above, use cooling mode to adjust charge. When to use heating modewhen the outdoor temperature is below 60 F (15 C), use the heating mode to adjust the charge. Adding Charge for Indoor Match UpTable 5 lists all the Lennox recommended indoor unit matches along with the charge levels for the various sizes of outdoor units. Page 15 XP14 SERIES

Adding Charge per Indoor Unit Match using Subcooling Method 1 Check the airflow as illustrated in figure 23 on page 15 to be sure the indoor airflow is as required. (Make any air flow adjustments before continuing with the following procedure.) 2 Measure outdoor ambient temperature; determine whether to use cooling mode or heating mode to check charge. 3 Connect gauge set. 4 Check Liquid and Vapor line pressures. Compare pressures with Normal Operating Pressures table 7, (Table 7 is a general guide. Expect minor pressure variations. Significant differences may mean improper charge or other system problem.) 5 Set thermostat for heat/cool demand, depending on mode being used: Using cooling modewhen the outdoor ambient temperature is 60 F (15 C) and above. Target subcooling values in table below are based on 70 to 80 F (21 27 C) indoor return air temperature; if necessary, operate heating to reach that temperature range; then set thermostat to cooling mode setpoint to 68ºF (20ºC). When pressures have stabilized, continue with step 6. Using heating modewhen the outdoor ambient temperature is below 60 F (15 C). Target subcooling values in table below are based on 65 75 F (18 24 C) indoor return air temperature; if necessary, operate cooling to reach that temperature range; then set thermostat to heating mode setpoint to 77ºF (25ºC). When pressures have stabilized, continue with step 6. 6 Read the liquid line temperature; record in the LIQº space. 7 Read the liquid line pressure; then find its corresponding temperature in the temperature/ pressure chart listed on page 18 and record it in the SATº space. 8 Subtract LIQº temp. from SATº temp. to determine subcooling; record it in SCº space. 9 Compare SCº results with table below, being sure to note any additional charge for line set and/or match up. 10 If subcooling value is greater than shown in table, remove refrigerant; if less than shown, add refrigerant. 11 If refrigerant is added or removed, repeat steps 5 through 10 to verify charge. 505244M 10/09 Page 16
