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 sym-

bols. Failure to heed safety information increases the risk of

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

HIPPING

NSPECTION

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 ac-

cessories are correct prior to installation. The distributor or manu-

facturer will not accept claims from dealers for transportation

damage or installation of incorrectly shipped units.

& 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 72 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

residential 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 introduction

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 strongly discouraged.

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.

EATURES

This heat pump is a part of the ComfortNet™ family of products. It may be installed as part of a “legacy” system using a

standard 24 VAC thermostat. However, with the CTK0* ComfortNet™ thermostat kit, this heat pump may be installed as part of

a digitally communicating system. The ComfortNet system provides automatic airflow configuration, enhanced setup features,

and enhanced diagnostics. It also reduces the number of thermostat wires to a maximum of four and a minimum of two.

CONDENSING UNIT HEAT PUMP INSTALLATION & SERVICE REFERENCE © 2009-2014 Goodman Manufacturing Company, L.P. 5151 San Felipe, Suite 500, Houston, TX 77056 www.goodmanmfg.com -or- www.amana-hac.com P/N: IO-348M Date: September 2014 IMPORTANT SAFETY INSTRUCTIONS The following symbols and labels are used throughout this manual to indicate immediate or potential safety hazards.
PAGE 2
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. Where possible, the top of the unit should be completely unobstructed; however, if vertical conditions require placement beneath an obstruction there should be a minimum of 60 inches between the top of the unit and the obstruction(s).
PAGE 3
WARNING WARNING REFRIGERANTS ARE HEAVIER THAN AIR. THEY CAN “PUSH OUT” THE OXYGEN IN YOUR LUNGS OR IN ANY ENCLOSED SPACE . TO AVOID POSSIBLE DIFFICULTY IN BREATHING OR DEATH : • NEVER PURGE REFRIGERANT INTO AN ENCLOSED ROOM OR SPACE. BY LAW , ALL REFRIGERANTS MUST BE RECLAIMED . • IF AN INDOOR LEAK IS SUSPECTED , THOROUGHLY VENTILATE THE AREA BEFORE BEGINNING WORK . • LIQUID REFRIGERANT CAN BE VERY COLD. TO AVOID POSSIBLE FROST BITE OR BLINDNESS, AVOID CONTACT AND WEAR GLOVES AND GOGGLES.
PAGE 4
BURYING REFRIGERANT LINES If burying refrigerant lines can not be avoided, use the following checklist. 1. Insulate liquid and suction lines separately. 2. Enclose all underground portions of the refrigerant lines in waterproof material (conduit or pipe) sealing the ends where tubing enters/exits the enclosure. 3. If the lines must pass under or through a concrete slab, ensure lines are adequately protected and sealed.
PAGE 5
SYSTEM EVACUATION WARNING NOTE: Scroll compressors should never be used to evacuate or pump down a heat pump or air conditioning system. 1. Connect the vacuum pump with 250 micron capability to the service valves. 2. Evacuate the system to 250 microns or less using suction and liquid service valves. Using both valves is necessary as some compressors create a mechanical seal separating the sides of the system. 3. Close pump valve and hold vacuum for 10 minutes.
PAGE 6
LOW VOLTAGE CONNECTIONS Condensing unit control wiring requires a nominal 24 VAC (+/- 6 VAC), 60 Hz, minimum 25 VA service from either the indoor or an optional outdoor transformer. Low voltage wiring for the condensing units depends on the thermostat used. The unit is designed to work as part of a fully communicating HVAC system utilizing the ComfortNet™ CTK0* thermostat, ComfortNet™ compatible indoor unit, and up to four wires.
PAGE 7
Do not introduce liquid refrigerant from the cylinder into the crankcase of the compressor as this may damage the compressor. 1. Break vacuum by fully opening liquid and suction base valves. 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. CHARGE VERIFICATION WARNING CAUTION REFRIGERANT UNDER PRESSURE! USE REFRIGERANT CERTIFIED TO AHRI STANDARDS.
PAGE 8
EXPANSION VALVE SYSTEM CAUTION NOTE: Units matched with indoor coils equipped with non-adjustable TXV should be charged by subcooling only. 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 ALL REFRIGERANT DURING SYSTEM REPAIR AND BEFORE FINAL UNIT Run the unit on low stage cooling for 10 minutes until refrigerDISPOSAL. ant pressures stabilize.

COMFORTNET™ SYSTEM OVERVIEW CT compatible Air Handler/Furnace/Modular Blower CT compatible Air Handler/Furnace/Modular Blower The ComfortNet system (or CT system) is a system that includes a ComfortNet compatible air handler/furnace/modular blower and air conditioner or heat pump with a CTK0* thermostat. Any other system configurations are considered invalid ComfortNet systems and must be connected as a traditional (or legacy) system. The following table compares the valid CT systems.
PAGE 10
CTK0* WIRING NOTE: Refer to section Electrical Connections - High Voltage Connections for 208/230 volt line connections to the air conditioner or heat pump. NOTE: A removable plug connector is provided with the control to make thermostat wire connections. This plug may be removed, wire connections made to the plug, and replaced. It is strongly recommended that you do not connect multiple wires into a single terminal. Wire nuts are recommended to ensure one wire is used for each terminal.

IDENTIFICATION Model Number, Serial Number and Software Version are displayed within this menu. A model number check will help determine if the equipment shared data is correct for the unit. If the model number is not correct, even though very rare, a memory card is available to load the proper data. SENSORS The outdoor ambient temperature and coil temperature are displayed in the Sensor Menu. This information can be used for troubleshooting purposes.

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 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. An indoor air filter must be used with your comfort system.
