Improper installation, adjustment, alteration, service

or maintenance can cause property damage, personal

injury or loss of life. Installation and service must be

performed by a licensed professional HVAC installer or

equivalent, service agency, or the gas supplier.

WARNING

The Clean Air Act of 1990 bans the intentional venting

of refrigerant (CFCs, HCFCs and HFCs) as of July

1, 1992. Approved methods of recovery, recycling or

reclaiming must be followed. Fines and/or incarceration

may be levied for noncompliance.

IMPORTANT

As with any mechanical equipment, contact with sharp

sheet metal edges can result in personal injury. Take

care while handling this equipment and wear gloves

and protective clothing.

Shipping and Packing List Package 1 of 1 contains: 1 – Assembled air handler unit factory-equipped for upflow or horizontal air discharge application (includes upflow and horizontal drain pans and pre-installed air filter) Check the air handler for shipping damage; if found, immediately contact the last carrier. Check the unit rating plate to confirm that delivered unit matches order. General The NAMP1 series air handler with aluminum coil is designed for indoor installation only.
PAGE 4
• The air handler evaporator coil, supply fan assembly and duct system must be thoroughly cleaned following final construction clean-up. • All air handler operating conditions must be verified according to these installation instructions. IMPORTANT Excessive condensation may occur if the unit is installed in a warm, humid place. When the unit is installed in an unconditioned space, apply sealant around electrical wires, refrigerant piping and condensate lines at the point where they enter the cabinet.
PAGE 5
For ease in installation, it is best to make any necessary coil configuration changes before setting air handler in place. Refrigerant Metering Device NAMP1 units are equipped with a factory-installed check/ expansion valve or an RFC device. Upflow Application 1. The air handler must be supported on the bottom only and set on solid floor or field-supplied support frame. Securely attach the air handler to the floor or support frame.
PAGE 6
Left-Hand Air Discharge 6. Rotate drip shield 180° front-to-back. For horizontal left-hand air discharge, the following field modifications are required. 7. Remove plastic plug from left hole on coil front end seal and reinstall plug in back hole. Reinstall drip shield screw in front coil end seal. Drip shield should drain downward into horizontal drain pan inside coil. 8. Rotate top cap 180º front-to-back and align with unused screw holes.

13. Set unit so that it is sloped 1/4ʺ toward the drain pan end of the unit. Connect return and supply air plenums as required using sheet metal screws. 14. If suspending the unit, it must be supported along the entire length of the cabinet. If using chain or strap, use a piece of angle iron or sheet metal attached to the unit (either above or below) so that the full length of the cabinet is supported. Use securing screws no longer than 1/2ʺ to avoid damage to coil or filter, as illustrated in Figure 3.
PAGE 8
2. Install properly sized, field-provided connection fittings and connect primary drain line to the main drain pan connection. NOTE: When installing drain line connection fittings to the drain pan, hand tighten the fitting and use a thread sealant. Over-tightening the fittings can split connections on the drain pan. 3. If the secondary drain line is to be used, remove the plug or the knockout and route the drain line so that water draining from the outlet will be easily noticed by the homeowner.

Duct System and Filters Field-Fabricated Return Air Duct Flange for Horizontal Applications Duct System A return air duct system is recommended, but not factoryprovided. If the unit is installed in a confined space or closet, run a full-size return connection to a location outside the closet. The air handler is provided with flanges for the connection of the supply plenum. Supply and return duct system must be adequately sized to meet the system’s air requirements and static pressure capabilities.

PLEASE READ IMPORTANT ISSUES CONCERNING BRAZING OPERATIONS IN THE BRAZING REFRIGERANT LINES SECTION BEFORE PROCEEDING. NOTE - Refer to outdoor unit installation instructions for refrigerant piping size requirements. NOTE - Use silver alloy brazing rods with five or six percent minimum silver alloy for copper-to-copper brazing; 45 percent alloy for copper-to-brass and copper-to-steel brazing. Do not use soft solder.
PAGE 11
Sealing the Unit 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. Seal the unit so that warm air is not allowed into the cabinet. Warm air introduces moisture, which results in water blowoff problems. This is especially important when the unit is installed in an unconditioned area.
PAGE 12
WARNING • This unit is provided with holes for conduit. Use provided caps to seal holes not used. • Typical unit wiring (as well as wiring of optional fieldinstalled electric heat) is given in Figure 16. Refer to the instructions provided with the electric heat section for proper installation. Electric Shock Hazard. Can cause injury or death. Unit must be properly grounded in accordance with national and local codes.

Change Blower Speed Air Flow – Cooling Blower Speed The cooling blower speed is factory configured to provide correct air flow for an outdoor unit that matches the cooling capacity rating of the air handler. If the outdoor unit is smaller than the maximum cooling capacity rating for the air handler, the cooling blower speed may need to be changed. Refer to blower performance chart in Table 4. 1. Disconnect all power supplies. 2. Remove the air handler access panel. 3.

Check Electric Heat (If Used) Checkout Procedures NOTE: Refer to outdoor unit installation instructions for system start-up instructions and refrigerant charging instructions. 1. Set thermostat to call for auxiliary heat (approximately 5°F above ambient temperature). The indoor blower and auxiliary heat should come on together. Allow a minimum of 3 minutes for all sequencers to cycle on. 2. Set the thermostat so that it does not call for heat. Allow up to 5 minutes for all sequencers to cycle off.
PAGE 19
Heating (Heat Pump) When the thermostat calls for heating, 24 volts is applied to the blower time-delay relay coil. Then, normally open contacts close, causing the indoor blower motor to operate. The circuit between R and Y is completed, closing the circuit to the contactor in the outdoor unit, starting the compressor and outdoor fan motor. If the room temperature continues to decrease, the circuit between R and W1 is completed by the second-stage heat room thermostat.

Professional Maintenance Homeowner Maintenance NOTICE IMPORTANT Failure to follow instructions will cause damage to the unit. This unit is equipped with an aluminum coil. Aluminum coils may be damaged by exposure to solutions with a pH below 5 or above 9. The aluminum coil should be cleaned using potable water at a moderate pressure (less than 50psi). If the coil cannot be cleaned using water alone, it is recommended to use a coil cleaner with a pH in the range of 5 to 9.
