Important Safety Instructions

The following symbols and labels are used throughout this

manual to indicate immediate or potential safety hazards. It is

the owner’s and installer’s responsibility to read and comply

with all safety information and instructions accompanying these

symbols. Failure to heed safety information increases the risk

of personal injury, property damage, and/or product damage.

HIGH VOLTAGE!

Disconnect ALL power before servicing.

Multiple power sources may be present.

Failure to do so may cause property damage,

personal injury or death.

WARNING

Installation and repair of this unit should be performed

by individuals meeting the requirements of an

“entry level technician” as specified by the

Attempting to install or repair this unit without such

background may result in product damage, personal

injury or death.

ONLY

Air

Conditioning, Heating and Refrigeration Institute (AHRI)

Scroll equipped units should never be used to evacuate

the air conditioning system. Vacuums this low can cause

internal electrical arcing resulting in a damaged or failed

compressor.

CAUTION

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 72 hours of operation. Rated

performance is delivered at the specified airflow. See outdoor

unit specification sheet for split system models or product speci-

fication 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 in cooling mode requires the use

of an approved low ambient kit.

Operating the unit in a structure that is not complete (either as

part of new construction or renovation) will void the warranty.

Installation Clearances

Special consideration must be given to location of the con-

densing unit(s) in regard to structures, obstructions, other units,

and any/all other factors that may interfere with air circulation.

Where possible, the top of the unit should be completely unob-

structed; however, if vertical conditions require placement be-

neath an obstruction there should be a minimum of 60

inches between the top of the unit and the obstruction(s).

The specified dimensions meet requirements for air circulation

only. Consult all appropriate regulatory codes prior to deter-

mining final clearances.

In more severe weather locations, it is recommended that the unit be elevated to allow unobstructed drainage and air flow. The following elevation minimums are recommended: Another important consideration in selecting a location for the unit(s) is the angle to obstructions. Either side adjacent the valves can be placed toward the structure provided the side away from the structure maintains minimum service clearance. Corner installations are strongly discouraged.

Refrigerant Lines CAUTION The compressor POE oil for R-410A units is extremely susceptible to moisture absorption and could cause compressor failure. Do not leave system open to atmosphere any longer than necessary for installation. Use only refrigerant grade (dehydrated and sealed) copper tubing to connect the condensing unit with the indoor evaporator. After cutting the tubing, install plugs to keep refrigerant tubing clean and dry prior to and during installation.

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.

Adequate refrigerant charge for the matching HSVTC evaporator coil and 15 feet of lineset is supplied with the condensing unit. If using evaporator coils other than HSVTC coil, it may be necessary to add or remove refrigerant to attain proper charge. If line set exceeds 15 feet in length, refrigerant should be added at .6 ounces per foot of liquid line. NOTE: Charge should always be checked using superheat when using a piston and subcooling when using TXV equipped indoor coil to verify proper charge.

Final Charge Adjustment Charge Verification REFRIGERANT UNDER PRESSURE! 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. • Do not overcharge system with refrigerant. • Do not operate unit in a vacuum or at negative pressure. Failure to follow proper procedures may cause property damage, personal injury or death. Purge gauge lines. Connect service gauge manifold to basevalve service ports.

Fixed Orifice 1. 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. 2. Refer to the superheat table provided for proper system superheat. Add charge to lower superheat or recover charge to raise superheat. If subcooling is low and superheat is high, add charge to raise subcooling to 7 to 9 ºF then check superheat. c.

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.
