Minimum Unit Clearances 4 √ The cooling load of the area to be conditioned must be calculated and a system of the proper capacity selected. It is recommended that the area to be conditioned be completely insulated and vapor sealed. √ Check the electrical supply and verify the power supply is adequate for unit operation. If there is any question concerning the power supply, contact the local power company. √ All units are securely packed at the time of shipment and upon arrival should be carefully inspected for damage prior to installing the equipment at the job site. Verify coil fins are straight. If necessary, comb fins to remove flattened or bent fins. Claims for damage should be filed immediately with the carrier. √ Please consult your dealer for maintenance information and availability of maintenance contracts. Please read all instructions before installing the unit. Locating the Heat Pump 12" 24" Before You Install this Unit • Survey the job site to determine the best location for mounting the outdoor unit. Select a solid, level position, preferably on a concrete slab, slightly above the grade level, and parallel to the home. If possible, select a site for the unit that is as close as possible to the proposed return grille location. DO NOT PLACE UNIT UNDER THE HOME. • The unit should be located with consideration of minimizing the length of the supply and return ducts with no sharp radius bends. If practical, place the heat pump and its ducts in an area where they will be shaded from the afternoon sun, when the heat load is greatest. • Consideration should also be given to availability of electric power, service access, noise, and shade. • Overhead obstructions, poorly ventilated areas, and areas subject to accumulation of debris should be avoided. The hot condenser air must be discharged up and away from the home, and if possible, in a direction with the prevailing wind. Do not place the unit in a confined space. See Figure 8 (page 13) for unit dimensions. • Sufficient clearance for unobstructed airflow through the outdoor coil must be maintained in order to achieve rated performance. For minimum clearances to obstructions, see Figure 1. Minimum Clearances Minimum clearances MUST be maintained from adjacent structures to provide room for proper servicing and air circulation. DO NOT install unit in a confined or recessed area that will allow discharge air from the unit to re-circulate into the condenser air inlet, through the coil. See Figure 1.

NFPA publications are available by writing to: National Fire Protection Association, Batterymarch Park, Quincy, ME 02269 or visit www.NFPA.org on the web. • Design the duct work according to methods described by the Air Conditioning Contractors of America (ACCA). • The supply duct system, including the number and type of registers, will have much more effect on the performance of the system than any other factor. The duct must be sufficiently large to conduct an adequate amount of air to each register. See Figure 3 (page 6). • Duct work should be attached directly to the unit flanges for horizontal applications. • For highly resistive duct systems it may be necessary to add an additional return air duct and or supply to achieve maximum performance and prevent coil icing and refrigerant flood back. • The heat pump system will not cool or heat the home if air is lost to the outside through leaks in the duct system. Ducts that are collapsed or restricted by foreign objects will also prevent adequate air flow. • All duct work passing through unconditioned space must be properly insulated to minimize duct losses and prevent condensation. Use insulation with an outer vapor barrier. Refer to local codes for insulation material requirements. Unconditioned Spaces The heat pump system will not cool or heat the home if air is lost to the outside through leaks in the duct system. Ducts that are collapsed or restricted by foreign objects will also prevent adequate air flow. HEAT PUMP INSTALLATION Unpacking the Unit It is recommended that the unit be unpacked at the installation site to minimize damage due to handling. CAUTION: Do not tip the unit on its side. Oil may enter the compressor cylinders and cause starting trouble. If unit has been set on its side, restore to upright position and do not run for several hours. Then run unit for a few seconds. Do this three or four times with five minutes between runs. 1.Remove the bands from around the unit. 2.Unfold the top and bottom cap flanges. 3.Carefully remove the top cap and tube. Installing Return & Supply Air Collars If the supply and return collars are supplied with the unit, they will be located in the supply duct. They can be easily positioned over the unit openings and secured with sheet metal screws. See Figure 2. • The diameter of the return duct collar is 14”. NOTE: 2 ton units are designed with 12” returns. • The diameter of the supply duct collar is 12”. • Before permanently installing the collars, it is recommended you pre-fit them over the openings first to determine best fit and alignment. Duct Dimples Transition ws Duct Scre ir Supply A ir Return A Figure 2.

Typical Duct Applications Supply Duct 1.Assemble the collar by overlapping the two ends. NOTE: One end of the collar is slotted and the opposite end has two small holes. Position the end with small screw holes underneath the slotted end. 2.Fasten the collar ends with two self drilling sheet metal screws. 3.Position the collar over the opening and align the 4 holes in the collar with the 4 holes (or dimples depending on model) in the rear panel. 4.Using self-drilling screws (10-16x.5), secure the collar to the rear panel. Return Duct 1.Assemble the collar by overlapping the two ends. NOTE: One end of the collar is slotted and the opposite end has two small holes. Position the end with small screw holes underneath the slotted end. 2.Fasten the collar ends with two self drilling sheet metal screws. 3.Position the collar over the opening. Align the four holes in the collar with the four dimples or holes (depending on unit model) in the panel. 4.Secure the collar to the rear panel using self tapping screws (10-16x.5). Connecting Return & Supply Air Flexible Ducts • Flexible ducts may be cut to the required length and spliced with sheet metal sleeves and clamps. Keep all ducts as short and straight as possible. Avoid sharp bends. Please follow all instructions packed with duct. • Flexible ducts can be secured to the corresponding collars with the provided clamps. After the inner duct is connected to the collar, pull the insulation and plastic sleeve over the connection and clamp. NOTE: To prevent a loss in cooling capacity, make sure all connections are tight. 6 • Homes with multiple supply ducts (or special applications), a Y fitting is available for dividing the supply air to different areas of the home for more efficient cooling. NOTE: For maximum performance, insulate the Y fitting. Locating & Installing the Return Air Assembly To simplify installation, locate and install the return air assembly first. See Figure 4 (page 7). If desired, the return opening can be located inside a closet with louvered doors that has an open area equal to or greater than a 12” x 20” grille. The return air grille can be placed in the wall of a closet and the ducted into the filter box through a boxed-in area at the closet floor level. Make sure the filter is readily accessible. NOTE: The return air box with grille and filter should not be located in heavy traffic areas like hallways or center of rooms. A good spot is in a corner or under a table, if a minimum two inch clearance is available. 1.Start the installation from under the home by cutting a small hole in the sub-floor. Determine how the floor joist location will affect cutting the opening needed for the return air box. NOTE: Floor joists are generally located on 16” centers, leaving 14-3/8” between joists. 2.After measuring the return air box (approximately 121/4” x 20-1/4”), cut the hole through the floor so that the box will fit between the floor joists. Care should be taken when cutting through carpeting to avoid snags. NOTE: In most installations it will be necessary to cut a similar hole in the fiberboard directly under the hole in the floor. However, if the floor is more than ten inches deep, it will only be necessary to cut a hole for the collar on the return air box or for the insulated duct. 3.Set the box into the opening and fasten with screws or nails. 4.Install the filter and return air grille in place. Locating & Installing the Supply Damper(s) When locating the supply damper(s), carefully check floor joists and frame members that could interfere with the installation of the damper or flexible duct. Ideally, the damper (Figure 5) should be located in the bottom of the main duct, forward of center of the home, at least three feet from the nearest register. The round supply opening in the slanted side of the damper should face the side of the home where the heat pump is located. Figure 4. Return Air Assembly 1.Locate the center of the heat duct by cutting a small hole in the fiberboard below the duct at the desired location. 2.Cut a hole approximately 3/4” larger than the damper opening in the fiberboard. 3.Cut a 9-1/8” x 13-1/8” hole in the duct and bend over all tabs flat on the inside of the heat duct. 4.Insert the damper into the duct and bend over all tabs flat on the inside of the heat duct. 5.Seal the opening between the fiberboard and damper or flexible duct. Condensate Drainage AUTOMATIC DAMPER IS CLOSED WHEN HEAT PUMP IS OFF Figure 5. Supply Damper A 3/4” condensate fitting extends out of the side of the unit as shown in Figure 6. The drain trap, shipped in the electrical compartment, must be installed to prevent water from collecting inside the unit. 1.Thread the elbow provided with the unit into the drain connection until hand tight. 2.Connect the condensate tubing onto the fitting, forming a trap (Figure 6) near the drain connection. 3.Route the condensate tube from the trap to a suitable drain. NOTE: For proper drainage, make sure the trap is level to the ground and tubing outlet is below trap level. Elbow P-Trap Figure 6.

Verify that the indoor blower, outdoor fan, and compressor energize and the cooling function starts. 5.Verify the discharge air grilles are adjusted and the system air is balanced. 6.Verify the duct work has no air leaks. 7.Verify the condensate drain is installed correctly and functions properly. 8.Set the temperature mode above room temperature. The unit should stop. 9.Instruct the homeowner on unit and thermostat operation and filter servicing. Air Circulation Leave the thermostat system mode on OFF, and set the fan mode to ON. Blower should run continuously. Check the air delivery at the supply registers and adjust register openings for balanced air distribution. Examine ducts for leaks or obstruction if insufficient air is detected. Set the thermostat fan mode to AUTO. The blower should stop running. System Heating Set the thermostat system mode to HEAT and the fan mode to AUTO. Change the thermostat temperature selector above the existing room temperature and check for the discharge of warm air at the supply registers. System Cooling Set the thermostat’s system mode to COOL and the fan mode to AUTO. Change the thermostat temperature selector below the existing room temperature. Allow the cooling system to operate for several minutes and check for the discharge of cool air at the supply registers. Short Cycle Protection The control circuit is equipped with a time-delay feature for protection against short cycling. With the system operating in the cooling mode, gradually raise the thermostat temperature setting until the whole system deenergizes. Immediately lower the thermostat temperature to the original setting and verify that the indoor blower is energized. After approximately 5 minutes the compressor and the outdoor fan will energize. Emergency Heat (Available only when Electric heat is supplied) Set the thermostat’s system mode to EM HT and the fan mode to either AUTO (intermittent air) or to ON (continuous air). Change the thermostat’s temperature selector above the existing room temperature and check the following: 1.The thermostat auxiliary heat light (RED) should be on. 2.The heat pump compressor and the fan should not run; low voltage circuit remains energized. 3.The blower will run according to the thermostat’s fan mode setting. Anti Short Cycle Timer Test The 5 minute time delay feature can be bypassed by shorting the TEST pins together. Heating Mode When the TEST pins are shorted together for more than 1 second, the control will switch between defrost mode and heating mode. Cooling Mode When the TEST pins are shorted together for more than 1 second, the Anti Short Cycle Timer will be bypassed. Unit MAINTENANCE WARNING: To prevent electrical shock, personal injury, or death, disconnect all electrical power to the unit before performing any maintenance or service. The unit may have more than one electrical supply. Proper maintenance is important to achieve optimum performance from the heat pump. The ability to properly perform maintenance on this equipment requires certain mechanical skills and tools. If you do not possess these skills, contact your dealer for maintenance. Consult your local dealer about the availability of maintenance contracts. Routine maintenance should include the following: 11 • Inspect and clean or replace air filters at the beginning of each heating and cooling season, or more frequently if required. • Inspect the condensate drain and outdoor coil at the beginning of each cooling season. Remove any debris. Clean the outdoor coil and louvers as necessary using a mild detergent and water. Rinse thoroughly with water. • Inspect the electrical connections for tightness at the beginning of each heating and cooling season. Service as necessary. CAUTION: The unit should never be operated without a filter in the return air system. Replace disposable filters with the same type and size. • Do not attempt to add additional oil to motors unequipped with oil tubes. The compressor is hermetically sealed at the factory and does not require lubrication. Adjustment of Refrigerant Charge CAUTION: This heat pump contains liquid and gaseous refrigerant under pressure. Adjustment of refrigerant charge should only be attempted by qualified, trained personnel thoroughly familiar with the equipment and safe responsible refrigerant handling procedures. Under no circumstances should the homeowner attempt to install and/or service this equipment. Failure to comply with this warning could result in equipment damage, personal injury, or death. Charging the Unit in AC Mode (with Outdoor Temperatures Above 65° F) 1.With the system operating at steady-state, measure the suction and liquid refrigerant pressures (in psig) at the service valves. 2.Measure the compressor discharge temperature (° F). 3.Use Table 4 (page 14), Table 5 (page 14), Table 6 (page 15), Table 7 (page 15), Table 8 (page 16), or Table 9 (page 16) to verify system conditions (during cooling mode) for proper charge amount. Charging the Unit in Heating Mode 1.Evacuate the refrigerant system. 2.Use Table 10 (page 17), Table 11 (page 17), Table 12 (page 17), Table 13 (page 18), Table 14 (page 18), or Table 15 (page 18), as a guide and weigh in the proper charge as shown on the unit rating plate (during heating mode operation). NOTE: Unit charge MUST be verified in cooling season. 3.Verify the unit is operating properly according to the System Heating section on page 11. Safety Switches • The low pressure switch (if equipped) is factory installed and located in the suction line internal to the unit. The switch is designed to protect the compressor if a loss of charge occurs. Under normal conditions, the switch is closed. If the suction pressure falls below 5 psig, then the switch will open and de-energize the unit. The switch will close again once the suction pressure increases above 20 psig. The low pressure switch interrupts the thermostat inputs to the unit. NOTE: When the switch opens and then closes, there will be a 5 minute short cycling delay before the unit can energize. • The high pressure switch is factory installed and located in the compressor discharge line internal to the unit. The switch is designed to de-energize the system when very high pressures occur during abnormal conditions. Under normal conditions, the switch is closed. If the discharge pressure rises above 650 psig, the switch will open and de-energize the unit. The switch will close again once the discharge pressure decreases to 460 psig. The high pressure switch interrupts the thermostat inputs to the unit. NOTE: When the switch opens and then closes, there will be a 5 minute short cycling delay before the unit can energize. 12 figures & tables W Top View 1.75 Ø Electric Heater Power Supply L 1.125 Ø Power Supply 0.875 Ø Low Voltage Supply Side View H Control Access Panel 17.86 15.36 Blower Access Panel 10.10 5.5 3.2 B 18.01 12.13 Opening for 14" Diameter Return Duct Opening for 12" Diameter Supply Duct 3/4" NPT Drain Connection 1.38 A 3” 1" 3.2 5.29 Rear View 10.15 9.15 3.15 9.0 17.50 1” Model Number Length (L) Width (W) Height (H) A B 024K 49 35 30.2 35.02 2.48 030K 49 35 30.2 35.02 2.48 036K 49 35 30.2 35.02 2.48 042K 49 35 30.2 35.02 2.48 048K 63 35 38.2 35.02 2.48 060K 63 35 38.2 35.02 2.48 Figure 8.
