035-19084-001-D-0504 INSTALLATION INSTALLATION SAFETY INFORMATION: Read these instructions before continuing this appliance installation. This is an outdoor combination heating and cooling unit. The installer must assure that these instructions are made available to the consumer and with instructions to retain them for future reference. 1. Refer to the furnace rating plate for the approved type of gas for this furnace. • Local gas utility requirements. In Canada: • Current Canadian Electrical Code C22.
035-19084-001-D-0504 6. Maintain level tolerance to 1/2 inch maximum across the entire length or width of the unit. Excessive exposure of this furnace to contaminated combustion air may result in equipment damage or personal injury. Typical contaminates include: permanent wave solutions, chlorinated waxes and cleaners, chlorine based swimming pool chemicals, water softening chemicals, carbon tetrachloride, Halogen type refrigerants, cleaning solvents (e.g.
035-19084-001-D-0504 DUCTWORK Ductwork should be designed and sized according to the methods in Manual Q of the Air Conditioning Contractors of America (ACCA). A closed return duct system shall be used. This shall not preclude use of economizers or outdoor fresh air intake. The supply and return air duct connections at the unit should be made with flexible joints to minimize noise. The supply and return air duct systems should be designed for the CFM and static requirements of the job.
035-19084-001-D-0504 COMPRESSORS Units are shipped with compressor mountings factoryadjusted and ready for operation. Do not loosen compressor mounting bolts. FILTERS FIGURE 3 - FIXED OUTDOOR AIR DAMPER CONDENSATE DRAIN Two-inch filters are supplied with each unit, but units can be converted easily to four-inch filters. Filters must always be installed ahead of the evaporator coil and must be kept clean or replaced with same size and type.

035-19084-001-D-0504 THERMOSTAT The room thermostat should be located on an inside wall approximately 56 inches above the floor where it will not be subject to drafts, sun exposure or heat from electrical fixtures or appliances. Follow the manufacturer’s instructions enclosed with the thermostat for general installation procedure. A minimum of seven color-coded insulated wires (#18 AWG) should be used to connect the thermostat to the unit.

035-19084-001-D-0504 Natural gas may contain some propane. Propane, being an excellent solvent, will quickly dissolve white lead or most standard commercial compounds. Therefore, a special pipe compound must be applied when wrought iron or steel pipe is used. Shellac base compounds such as Gaskolac or Stalastic, and compounds such as Rectorseal #5, Clyde’s or John Crane may be used. 7.

Knowing the pressure drop across a dry coil, the actual CFM through the unit can be determined from the curve in Pressure Drop vs. Supply Air CFM Figure 17. 3.

035-19084-001-D-0504 INTERMITTENT BLOWER With the room thermostat fan switch set to "AUTO" and the system switch set to either the "AUTO" or "HEAT" settings, the blower is energized whenever a cooling or heating operation is requested. The blower is energized after any specified delay associated with the operation. When energized, the indoor blower has a minimum run time of 30 seconds. Additionally, the indoor blower has a delay of 10 seconds between operations.
035-19084-001-D-0504 MOTORIZED OUTDOOR AIR DAMPERS - This system operation is the same as the units with no outdoor air options with one exception. When the "R" to "G" circuit is complete, the motorized damper drives open to a position set by the thumbwheel on the damper motor. When the "R" to "G" circuit is opened, the damper spring returns fully closed. COOLING OPERATION ERRORS Each cooling system is monitored for operation outside of the intended parameters. Errors are handled as described below.

A low-pressure switch to protect against loss of refrigerant charge, (opens at 7 ± 3 psig and resets at 22 ± 5 psig). The above pressure switches are hard-soldered to the unit.

Indoor blower operation is initiated upon a call for first stage cooling, second stage cooling or dehumidification. When the room thermostat calls for first stage cooling while there is still a call for dehumidification, no operational change is made. The unit continues to operate both stages of compression with system #1 in the reheat mode.

035-19084-001-D-0504 SHUT DOWN 1. Set the thermostat to highest temperature setting. 1. Check for gas leaks in the unit piping as well as the supply piping. 2. Turn off the electrical power to the unit. START-UP (GAS HEAT) PRE-START CHECK LIST Complete the following checks before starting the unit. 1. Check the type of gas being supplied. Be sure that it is the same as listed on the unit nameplate. 2. Make sure that the vent and combustion air hoods have been properly installed.
035-19084-001-D-0504 Adjust as follows: 3. Remove the gas piping closure panel. 1. Remove the cap on the regulator. It’s located next to the push-on electrical terminals. 4. Disconnect wiring to the gas valves and spark ignitors. Remove the manifold-burner gas valve assembly by lifting up and pulling back. 2. To decrease the gas pressure, turn the adjusting screw counterclockwise. 3. To increase the gas pressure, turn the adjusting screw clockwise.

If M3 is not pulled in, check for 24 volts at the M3 coil. If 24 volts are present at M3 but M3 is not pulled in, replace the contactor. 6. Failing the above, if there is line voltage supplied at M3, M3 is pulled in, and the supply air blower motor still does not operate, replace the motor. 7.
035-19084-001-D-0504 on the UCB. The UCB will flash the last five alarms on the LED. If the compressor is locked out, cancel any call for cooling. This will reset any compressor lock outs. NOTE: While the above step will reset any lockouts, compressor #1 may be held off for the ASCD. See the next step. 10. If 24 volts is present at the UCB Y1 terminal and none of the switches are open and the compressor is not locked out, the UCB may have the compressor in an ASCD.
035-19084-001-D-0504 6. If 24 volts is not present at M2, check for 24 volts at the UCB terminal, C2. If 24 volts are present, check for loose wiring between C2 and the compressor contactor. 7. If 24 volts is not present at the C2 terminal, check for 24 volts from the room thermostat at the UCB Y2 terminal. If 24 volts is not present from the room thermostat, check for the following: a. 24 volts at the thermostat Y2 terminal. b. Proper wiring between the room thermostat and the UCB, i.e.
035-19084-001-D-0504 8. If 24 volts are present at the UCB Y1 terminal, the compressor may be out due to an open high-pressure switch, low-pressure switch, or freezestat. Check for 24 volts at the HPS1, LPS1, and FS1 terminals of the UCB. If a switch has opened, there should be a voltage potential between the UCB terminals, e.g. if LPS1 has opened, there will be a 24volt potential between the LPS1 terminals. 9.
035-19084-001-D-0504 NOTE: To find the Btu input, multiply the number of cubic feet of gas consumed per hour by the Btu content of the gas in your particular locality (contact your gas company for this information - it varies widely from city to city.). The furnace may shut down on a high temperature condition during the procedure. If this occurs, the UCB energize the supply air blower motor until the high temperature limit has reset.
035-19084-001-D-0504 5. If the (RW1) relay is not pulled in, check for 24 volts at the (RW1) coil. If 24 volts is present, replace the (RW1) relay. If 24 volts is not present, check for a loose 24 volt connection back to the relay board and check the connections from the room thermostat to the relay board. If all connections are correct, replace the relay board. The draft motor runs but the furnace does not light and the sparker does not spark. 1.
035-19084-001-D-0504 1. Make the same checks and adjustment as described in “PILOT CHECKOUT” page 63. 2. Check the supply pressure as described in “POST START CHECK LIST” page 62. Make adjustments as necessary. 3. Make sure that the pilot burner is not bent or damaged. 4. Make sure that the ground connections at the pilot burner, gas valve and ignitor control are intact. Check the high tension wire for good electrical connection. If all are intact, replace the ignitor module.
