A/GPUM3 13.4 SEER2 “M” SERIES With R-410A Single Package Gas-Electric Ultra-Low Nox Heating & Cooling Unit WARNING Only personnel that have been trained to install, adjust, service, maintenance or repair (hereinafter, “service”) the equipment specified in this manual should service the equipment. The manufacturer will not be responsible for any injury or property damage arising from improper service or service procedures.

PAGE 3
HIGH ALTITUDE KIT Manifold pressure adjustments and ID plug change are required for all installations above 4500 ft. The conversion from “standard altitude” (as shipped from the factory) to “high altitude” requires: • Replacing ID plug • Adjusting manifold pressure Before proceeding, shut OFF gas supply at manual shut-off and turn off power to the unit.
PAGE 4
Safety Considerations IMPORTANT NOTE: This unit is designed to meet the NOX requirement of 14Ng/J maximum as required by the South Coast Air Quality Management District and the San Joaquin Valley Air Pollution Control District, both in the State of California, and is intended for installation in those districts only. WARNING Should overheating occur or the gas supply fail to shut off, turn off the manual gas shutoff valve external to the furnace before turning off the electrical supply.
PAGE 5
WARNING This unit must not be used as a “construction heater” during the finishing phases of construction on a new structure. This type of use may result in premature failure of the unit due to extremely low return air temperature and exposure to corrosive or very dirty atmospheres.

Obtain from: American National Standards Institute 25 West 43rd Street, 4th Floor New York, NY 10036 WARNING CARBON MONOXIDE POISONING HAZARD Failure to follow the steps outlined below for each appliance connected to the venting system being placed into operation could result in carbon monoxide poisoning or death. Transportation Damage Check the carton upon arrival for external damage. If damage is found, a request for inspection by carrier agent should be made in writing immediately.
PAGE 7
All Installations: • For proper flame pattern within the heat exchanger and proper condensate drainage, the unit must be mounted level. • The flue outlet hood must be at least 12 inches from any opening through which flue gases could enter a building,and at least three feet above any forced air inlet located within ten feet. The economizer/ manual fresh air intake/motorized fresh air intake and combustion air inlet mounted on the unit are not affected by this restriction.
PAGE 8
• • Close to the wall application assures free, unobstructed air to the other two sides. In more confined application spaces, such as corners provide a minimum 12” clearance on all air inlet sides. Allow 36” minimum for service access to the compressor compartment and controls. Unit should be located a minimum of 4” away from the wall with the connections facing the wall. • • The unit may be installed directly on wood floors or on Class A, Class B, or Class C roof covering material.
PAGE 9
Refer to the Roof Curb Installation Instructions for proper curb installation. Curbing must be installed in compliance with the National Roofing Contractors Association Manual. CAUTION To prevent unreliable operation or equipment damage, the inlet gas supply pressure must be as specified on the unit rating plate with all other household gas fired appliances operating. Lower unit carefully onto roof mounting curb.
PAGE 10
• • • • Rigid metallic pipe and fittings Semirigid metallic tubing and metallic fittings (Aluminum alloy tubing must not be used in exterior locations) Listed gas appliance connectors used in accordance with the terms of their listing that are completely in the same room as the equipment. In the prior two methods above the connector or tubing must be protected from physical and thermal damage.
PAGE 11
NOTE: Connect incoming power leads to terminals L1 & L2 on contactor in the electrical control section, using wire sizes specified in wiring table. codes, with the National Electrical Code, ANSI/NFPA No. 70, and/or the CSA C22.1 Electrical Code. Ensure low voltage connections are waterproof.
PAGE 12
Ductwork Duct systems and register sizes must be properly designed for the C.F.M. and external static pressure rating of the unit. Ductwork should be designed in accordance with the recommended methods of Air Conditioning Contractors of America Manual D (Residential) or Manual Q (Commercial). All ductwork exposed to the outdoors must include a weatherproof barrier and adequate insulation.
PAGE 13
CONDENSATE DRAIN Condensate Drain Connection A 3/4” NPT drain connection is supplied for condensate piping. An external trap must be installed for proper condensate drainage. DRAIN CONNECTION UNIT 2" MINIMUM FLEXIBLE TUBING-HOSE OR PIPE 3" MINIMUM A POSITIVE LIQUID SEAL IS REQUIRED Drain Connection NORMAL SEQUENCES OF OPERATION Heating This unit is equipped with an ignition control that automatically lights the main burner. DO NOT attempt to light the main burners by any other method. 1.
PAGE 14
STARTUP, ADJUSTMENTS, AND CHECKS Pre-Operation Checks 1. Close the manual gas valve external to the unit. 2. Turn off the electrical power supply to the unit. 3. Set the room thermostat to its lowest possible setting. 4. Remove the heat exchanger door on the side of the unit by removing screws. 5. This unit is equipped with an ignition device which automatically lights the main burner. DO NOT try to light burner by any other method. 6. Move the gas control valve switch to the OFF position. Do not force. 7.
PAGE 15
7. Turn OFF all electrical power and gas supply to the system. 8. Remove the manometer hose from the hose barb fitting or inlet pressure Tap. 9. Replace inlet pressure tap: a. White-Rodgers Valve: Turn inlet pressure test screw in to seal pressure port (clockwise, 7 in-lb minimum). 10. Retest for leaks. If bubbles form, shut down gas and repair leaks immediately. 11. If there are no leaks, turn ON electrical power and gas supply to the system. 12. Turn valve switch ON.
PAGE 16
1. Turn OFF gas to furnace at the manual gas shutoff valve external to the furnace. 2. Turn OFF all electrical power to the system. 3. Outlet pressure tap connections: a. White-Rodgers Valve: Back outlet pressure test screw (outlet pressure Tap) out one turn (counterclockwise, not more than one turn). 4. Connect manometer (or appropriate pressure gauge) at the gas valve outlet pressure tap. See WhiteRodgers 36J22Y-204 gas valve for location of outlet pressure tap. 5. Turn ON the gas supply. 6.

. Mode Total External Static 2. Measure the static pressure of the supply duct (Positive Pressure). 3. Add the two readings together. Checking Temperature Rise NOTE: Air temperature rise is the temperature difference between supply and return air. NOTE: Both readings may be taken simultaneously and read directly on the manometer is so desired.

To obtain the degrees temperature of superheat, subtract 50.0 from 59.0°F. The difference is 9° Superheat. The 9° Superheat would fall in the ± range of allowable superheat. b. If subcooling is low and superheat is high, add charge to raise subcooling then check superheat. c. If subcooling and superheat are high, adjust TXV valve superheat, then check subcooling. d. If subcooling is high and superheat is low, adjust TXV valve superheat and remove charge to lower the subcooling.

NOTE: Do not hold for longer than 5 seconds. Holding the button for 5 seconds or higher will erase the memory! Pressure Sensor The pressure sensor is mounted near induced draft blower. Its function is to regulate the induced draft blower’s speed in order to maintain proper air-fuel ratio for clean and reliable combustion.
PAGE 21
Low Flame Signal Under some conditions, the fuel or air supply can create a nearly invisible coating on the flame sensor. This coating acts as an insulator causing a drop in the flame signal. If the flame signal drops below a predetermined value, the ignition control will display an error code of (1) flash on the amber diagnostic LED. The unit will continue to operate until the control can no longer detect flame.
PAGE 22
Clean Outside Coil (Qualified Servicer Only) The coil with the outside air flowing over it should be inspected annually and cleaned as frequently as necessary to keep the finned areas free of lint, hair and debris. Burners Condenser, Evaporator, and Induced Draft Motors Bearings on the air circulating blower motor, condenser motor and the combustion fan motor are permanently lubricated. No additional oiling is required.
