Filters should be checked monthly especially since this unit may be used for both heating and cooling. CLEARANCES CONDENSATE DRAIN All units require certain clearances for proper operation and service. Refer to Figure 6 for the clearances required for combustion, construction, servicing and proper unit operation. A condensate trap is required to be installed in the condensate drain. The plumbing must conform to local codes. Use a sealing compound on male pipe threads. Install the condensate drain line (3⁄4“ NPTF) to spill into an open drain. WARNING: Do not permit overhanging structures or shrubs to obstruct the condenser air discharge outlet. DUCT WORK These units are adaptable to downflow use as well as rear supply and return air duct openings. To convert to downflow, use the following steps: 1. Remove the duct covers found in the bottom return and supply air duct openings. There are four (4) screws securing each duct cover (save these screws to use later). 2. Install the duct covers, removed in step one, to the rear supply and return air duct openings. Secure with the four (4) screws used in step one. 3. Seal the duct covers with silicone caulking. Downflow units must have an L-shaped supply duct without any outlets or registers located directly below the supply outlet of the unit. Duct work should be designed and sized according to the methods of the Air Conditioning Contractors of America (ACCA), as set forth in their Manual D. A closed return duct system shall be used. This shall not preclude use of economizers or ventilation air intake. Flexible joints may be used in the supply and return duct work to minimize the transmission of noise. CAUTION: When fastening duct work to the side duct flanges on the unit, insert the screws through the duct flanges only. DO NOT insert the screws through the casing. Outdoor duct work must be insulated and waterproofed. NOTE: Be sure to note supply and return openings. Refer to Figure 6 for information concerning rear and bottom supply and return air duct openings. FILTERS Single phase units are shipped without a filter and is the responsibility of the installer to secure a filter in the return air ductwork or install a Filter/Frame Kit (1FF0114). A filter rack and a filters are standard on three phase units. Filters must always be used and must be kept clean. When filters become dirt laden, insufficient air will be delivered by the blower, decreasing your units efficiency and increasing operating costs and wear-and-tear on the unit and controls. Unitary Products Group SERVICE ACCESS Access to all serviceable components is provided by the following removable panels: • Blower service access • Electrical/filter access • Compressor service access Refer to Figure 6 for location of these access panels and minimum clearance. THERMOSTAT The room thermostat should be located on an inside wall approximately 56" above the floor where it will not be subject to drafts, sun exposure or heat from electrical fixtures or appliances. Follow manufacturer’s instructions enclosed with the thermostat for general installation procedure. Four, five or six color coded insulated wires (minimum #18 AWG) should be used to connect thermostat to unit. See Figure 3. POWER AND CONTROL WIRING Field wiring to the unit must conform to provisions of the current N.E.C. ANSI/NFPA No. 70 or C.E.C. and/or local ordinances. The unit must be electrically grounded in accordance with local codes or, in their absence, with the N.E.C./C.E.C. Voltage tolerances which must be maintained at the compressor terminals during starting and running conditions are indicated on the unit Rating Plate and Table 1. The wiring entering the cabinet must be provided with mechanical strain relief. A fused or HACR breaker disconnect switch should be field provided for the unit. If any of the wire supplied with the unit must be replaced, replacement wire must be of the type shown on the wiring diagram. Electrical line must be sized properly to carry the load.

CAUTION: Do Not loosen compressor mounting bolts. Cooling The following sequences of operation are based on using a standard single-stage cooling thermostat. WITH POWER TO UNIT AND THERMOSTAT IN COOLING MODE. 1. If the fan switch on the thermostat is in the "ON" position, the 24 volts at "G" will energize the "K1" relay on the fan control board, close the "K1" relay contacts, and energize the indoor blower motor. If the fan switch is in the "AUTO" position, the blower will operate only when there is a call for cooling by the thermostat. 2. On a call for cooling, the thermostat will send 24 volts to "Y" on the fan control board. The 24 volt signal will energize contactor "M1", and power will be supplied to the compressor and outdoor fan motor. If the fan switch on the thermostat is on the "AUTO" position, the thermostat will also send a 24 volt signal to "G" on the fan control board and the indoor blower will operate as indicated in step 1. when the 24 volt "Y" signal is removed. If the fan switch on the thermostat is in the "ON" position, the indoor blower will continue to run. If the fan switch is in the "AUTO" position, the 24 volt "G" signal will be removed, and after a 60 second delay, the "K1" relay will open and de-energize the indoor blower motor.

The 24 volts signal will energize relay "K2" on the fan control board, and the first stage of electric heat will be energized. The indoor blower will operate as indicated in step 1. 3. On units with 2 (two) stages of electric heat, the second bank of heaters will be energized by a 24 volt signal to "W2" on the fan control board. After a 20 second delay, the third bank of heaters will be energized if the unit is so equiped. 4. When the heating demand is satisfied, the electric heat will be de-energized when the 24 volt "W1" and "W2" signals are removed. If the fan switch on the thermostat is in the "ON" position, the indoor blower will continue to run. If the fan switch is in the "AUTO" position, the indoor motor will shut off after the appropriate time delay. Please refer to Table 14 and 15 for more information.
