should service the equipment. The manufacturer will not be

responsible for any injury or property damage arising from improper

service or service procedures. If you service this unit, you assume

responsibility for any injury or property damage which may result. In

addition, in jurisdictions that require one or more licenses to service

the equipment specified in this manual, only licensed personnel

should service the equipment. Improper installation, adjustment,

servicing or repair of the equipment specified in this manual, or

attempting to install, adjust, service or repair the equipment specified

Shipping Inspection

Always keep the unit upright; laying the unit on its side or top

may cause equipment damage. Shipping damage, and subse-

quent investigation is the responsibility of the carrier. Verify

the model number, specifications, electrical characteristics,

and accessories are correct prior to installation. The distribu-

tor or manufacturer will not accept claims from dealers for trans-

portation damage or installation of incorrectly shipped units.

Codes & Regulations

This product is designed and manufactured to comply with

national codes. Installation in accordance with such codes and/

or prevailing local codes/regulations is the responsibility of the

installer. The manufacturer assumes no responsibility for equip-

ment installed in violation of any codes or regulations. Rated

performance is achieved after 20 hours of operation. Rated per-

formance is delivered at the specified airflow. See outdoor unit

specification sheet for split system models or product specifi-

cation sheet for packaged and light commercial models. Speci-

fication sheets can be found at www.goodmanmfg.com for

Goodman

brand products or www.amana-hac.com for Amana

brand products. Within either website, please select the resi-

dential or commercial products menu and then select the

submenu for the type of product to be installed, such as air

conditioners or heat pumps, to access a list of product pages

that each contain links to that model’s specification sheet.

The United States Environmental Protection Agency (EPA)

has issued various regulations regarding the introduc-

tion and disposal of refrigerants. Failure to follow these

regulations may harm the environment and can lead to

the imposition of substantial fines. Should you have any

questions please contact the local office of the EPA.

If replacing a condensing unit or air handler, the system must

be manufacturer approved and Air Conditioning, Heating and

Refrigeration Institute (AHRI) matched. NOTE: Installation of

unmatched systems is not allowed.

Outdoor units are approved for operation above 55°F in cooling

mode. Operation below 55°F requires the use of an approved

low ambient kit. Note: LAKT01 Low ambient kit cannot be used

with outdoor units containing ECM motors.

Damage to the unit caused by operating the unit in a structure

that is not complete (either as part of new construction or reno-

vation) is not covered under the warranty.

the unit can vibrate during operation, sound vibration transmission should be considered when installing the unit. Vibration absorbing pads or springs can be installed between the condensing unit legs or frame and the roof mounting assembly to reduce noise vibration. Installation Clearances Special consideration must be given to location of the condensing unit(s) in regard to structures, obstructions, other units, and any/all other factors that may interfere with air circulation.

To avoid possible explosion, use only returnable (not disposable) service cylinders when removing refrigerant from a system. • Ensure the cylinder is free of damage which could lead to a leak or explosion. • Ensure the hydrostatic test date does not exceed 5 years. • Ensure the pressure rating meets or exceeds 400 PSIG. When in doubt, do not use cylinder. Refrigerant Lines CAUTION The compressor POE oil for R-410A units is extremely susceptible to moisture absorption and could cause compressor failure.

Refrigerant Line Connections Leak Testing (Nitrogen or Nitrogen-Traced) IMPORTANT WARNING To avoid overheating the service valve, TXV valve, or filter drier while brazing, wrap the component with a wet rag, or use a thermal heat trap compound. Be sure to follow the manufacturer’s instruction when using the heat trap compound. Note: Remove Schrader valves from service valves before brazing tubes to the valves. Use a brazing alloy of 2% minimum silver content. Do not use flux.

The condensing unit rating plate lists pertinent electrical data necessary for proper electrical service and overcurrent protection. Wires should be sized to limit voltage drop to 2% (max.) from the main breaker or fuse panel to the condensing unit. Consult the NEC, CEC, and all local codes to determine the correct wire gauge and length. 5000 VACUUM IN MICRONS 4500 4000 LEAK(S) PRESENT 3500 Local codes often require a disconnect switch located near the unit; do not install the switch on the unit.

1. Break vacuum by fully opening liquid and suction base valves. Final Charge Adjustment The outdoor temperature must be 60°F or higher. Set the room thermostat to COOL, fan switch to AUTO, and set the temperature control well below room temperature. 2. Set thermostat to call for cooling. Check indoor and outdoor fan operation and allow system to stabilize for 10 minutes for fixed orifices and 20 minutes for expansion valves. Purge gauge lines. Connect service gauge manifold to basevalve service ports.

Temporarily install a thermometer 4-6" from the compressor on the suction line. Ensure the thermometer makes adequate contact and is insulated for best possible readings. Use vapor temperature to determine superheat. 3. TXV-based systems should have a Superheat value of 8°F +/- 1°F. 4.

SPLIT SYSTEMS AIR CONDITIONING AND HEAT PUMP HOMEOWNER’S ROUTINE MAINTENANCE RECOMMENDATIONS We strongly recommend a bi-annual maintenance checkup be performed before the heating and cooling seasons begin by a qualified servicer. Replace or Clean Filter Clean Outside Coil (Qualified Servicer Only) IMPORTANT NOTE: Never operate unit without a filter installed as dust and lint will build up on internal parts resulting in loss of efficiency, equipment damage and possible fire.
