HIPPING

NSPECTION

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

may cause equipment damage. Shipping damage, and subsequent

investigation is the responsibility of the carrier. Verify the model

number, specifications, electrical characteristics, and accessories

are correct prior to installation. The distributor or manufacturer

will not accept claims from dealers for transportation damage or

installation of incorrectly shipped units.

ODES

& R

EGULATIONS

This product is designed and manufactured to comply with na-

tional codes. Installation in accordance with such codes and/or

prevailing local codes/regulations is the responsibility of the in-

staller. 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 specifica-

tion sheet for packaged and light commercial models. Specifica-

tion 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 con-

ditioners 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 introduction and dis-

posal of refrigerants. Failure to follow these regulations may

harm the environment and can lead to the imposition of sub-

stantial fines.

IOG-4009G

“IMPORTANT - This product has been designed and manufactured to meet ENERGY STAR

criteria for energy efficiency when matched with appropriate coil components. However,

proper refrigerant charge and proper air flow are critical to achieve rated capacity and

efficiency. Installation of this product should follow the manufacturer’s refrigerant charging

and air flow instructions. Failure to confirm proper charge and air flow may reduce

energy efficiency and shorten equipment life.”

Proper sizing and installation of equipment is critical to achieving optimal performance. Split system

air conditioners and heat pumps must be matched with appropriate coil components to meet ENERGY STAR®

criteria. Ask your contractor for details or visit www.energystar.gov.

NOTICE THIS UNIT IS EQUIPPED WITH A 24 VAC TRANSFORMER THAT POWERS THE HEAT PUMP CONTROL BOARD. WHEN INSTALLED AS A COMMUNICATING SYSTEM, ONLY 2 WIRES ARE NEEDED BETWEEN INDOOR AND OUTDOOR EQUIPMENT. HOWEVER, WHEN INSTALLED AS A NON-COMMUNICATING (LEGACY) SYSTEM, THE TRANSFORMER WIRING (LOW VOLTAGE AND LINE VOLTAGE) MUST BE DISCONNECTED. REFER TO THE LOW VOLTAGE WIRING SECTION FOR MORE DETAILS. NOT RECOMMENDED B Should you have any questions please contact the local office of the EPA.

2. “Sweep” the refrigerant line with nitrogen or inert gas during brazing to prevent the formation of copper-oxide inside the refrigerant lines. The POE oils used in R-410A applications will clean any copper-oxide present from the inside of the refrigerant lines and spread it throughout the system. This may cause a blockage or failure of the metering device. 3. After brazing, quench the joints with water or a wet cloth to prevent overheating of the service valve. 4.

CAUTION WARNING PROLONGED OPERATION AT SUCTION PRESSURES LESS THAN 20 PSIG FOR MORE THAN 5 SECONDS WILL RESULT IN OVERHEATING OF THE SCROLLS AND PERMANENT DAMAGE TO THE SCROLL TIPS , DRIVE BEARINGS AND INTERNAL SEAL . TO AVOID THE RISK OF FIRE OR EQUIPMENT DAMAGE , USE COPPER CONDUCTORS. 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.

Adequate refrigerant charge for the matching evaporator coil or air handler and 15 feet of lineset is supplied with the condensing unit. If using evaporator coils or air handlers other than HSVTC coil it maybe 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.

EXPANSION VALVE SYSTEM NOTICE VIOLATION OF EPA REGULATIONS MAY RESULT IN FINES OR OTHER PENALTIES. CAUTION TO PREVENT PERSONAL INJURY, CAREFULLY CONNECT AND DISCONNECT MANIFOLD GAUGE HOSES . ESCAPING LIQUID REFRIGERANT CAN CAUSE BURNS . DO NOT VENT REFRIGERANT INTO THE ATMOSPHERE. RECOVER CAUTION Damage to the unit caused by operating the compressor with the suction valve closed is not covered under the warranty and may cause serious compressor damage.

3. Check subcooling and superheat. Systems with TXV application should have a subcooling of 6°F +/- 1°F and superheat of 8°F +/- 1°F. a. 6. A forced defrost can be initiated by pressing “TEST” and “RECALL” push buttons simultaneously for more than 1 second with a valid call for heat. The forced defrost can be terminated by If subcooling and superheat are low, adjust TXV to 8°F +/- 1°F superheat, then check subcooling.

System Heat Pump + Air Handler Heat Pump + Furnace System Operating Mode Airflow Demand Source Cooling Heat Pump Typical 18 AWG thermostat wire may be used to wire the system components. However, communications reliability may be improved by using a high quality, shielded, twisted pair cable for the data transmission lines. In either case, 150 feet is the maximum length of wire between indoor unit and outdoor unit, or between indoor unit and thermostat.

• COMFORTNET™ SYSTEM ADVANCED FEATURES The ComfortNet system permits access to additional system information, advanced setup features, and advanced diagnostic/ troubleshooting features. These advanced features are organized into a menu structure. See thermostat installation manual for directions on how to access the ComfortNet User Menus. See following tables for menu layout. Profile B ramps up to full cooling demand airflow by first stepping up to 50% of the full demand for 30 seconds.

THERMOSTAT MENU SYSTEM TROUBLESHOOTING If this heat pump is installed with a CT compatible furnace, the system is recognized as a dual fuel system. The balance point temperature should be set via the indoor unit. See indoor unit instruction manual for details on how to set the balance point. NOTE: Refer to the instructions accompanying the CT compatible indoor air handler/furnace/modular blower unit for troubleshooting information regarding indoor unit diagnostics..

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. Clean Outside Coil (Qualified Servicer Only) Replace or Clean Filter 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.
