IMPORTANT SAFETY INSTRUCTIONS Recognize Safety Symbols, Words, and Labels

The following symbols and labels are used throughout this manual to indicate immediate or potential hazards. It is the owner’s responsibility to read and comply with all safety information and instructions accompanying these symbols. Failure to heed safety information increases the risk of serious personal injury or death, property damage and/or product damage.

DANGER

IMMEDIATE HAZARDS WHICH WILL RESULT IN PROPERTY DAMAGE, PRODUCT DAMAGE, SEVERE PERSONAL INJURY OR DEATH.

WARNING

HAZARDS OR UNSAFE PRACTICES COULD RESULT IN PROPERTY DAMAGE, PRODUCT DAMAGE, SEVERE PERSONAL INJURY OR DEATH.

CAUTION

HAZARDS OR UNSAFE PRACTICES WHICH MAY RESULT IN PROPERTY DAMAGE, PRODUCT DAMAGE, PERSONAL INJURY OR DEATH.

WARNING

THE UNIT MUST HAVE AN UNINTERRUPTED, UNBROKEN ELECTRICAL GROUND TO MINIMIZE THE POSSIBILITY OF PERSONAL INJURY IF AN ELECTRICAL FAULT SHOULD OCCUR. THE ELECTRICAL GROUND CIRCUIT MAY CONSIST OF AN APPROPRIATELY SIZED ELECTRICAL WIRE CONNECTING THE GROUND LUG IN THE UNIT CONTROL BOX TO THE BUILDING ELECTRICAL SERVICE PANEL. OTHER METHODS OF GROUNDING ARE PERMITTED IF PERFORMED IN ACCORDANCE WITH THE “NATIONAL ELECTRIC CODE” (NEC)/”AMERICAN NATIONAL STANDARDS INSTITUTE” (ANSI)/”NATIONAL FIRE PROTECTION ASSOCIATION” (NFPA) 70 AND LOCAL/STATE CODES. IN CANADA, ELECTRICAL GROUNDING IS TO BE IN ACCORDANCE WITH THE CANADIAN ELECTRIC CODE CSA C22.1. FAILURE TO OBSERVE THIS WARNING CAN RESULT IN ELECTRICAL SHOCK THAT CAN CAUSE PERSONAL INJURY.

WARNING

BEFORE SERVICING OR INSTALLING THIS EQUIPMENT, THE ELECTRICAL POWER TO THIS UNIT MUST BE IN THE “OFF” POSITION. CAUTION, MORE THAN ONE DISCONNECT MAY EXIST. FAILURE TO OBSERVE THIS WARNING MAY RESULT IN AN ELECTRICAL SHOCK THAT CAN CAUSE PERSONAL INJURY.

WARNING

DUE TO HIGH SYSTEM PRESSURE AND ELECTRICAL SHOCK POTENTIAL, INSTALLING AND THE SERVICING AIR CONDITIONING SYSTEMS CAN BE HAZARDOUS. ONLY TRAINED AND QUALIFIED PERSONNEL ARE PERMITTED TO INSTALL OR SERVICE THIS EQUIPMENT. OBSERVE ALL WARNINGS CONTAINED IN THIS MANUAL AND LABELS/TAGS ATTACHED TO THE EQUIPMENT.

WARNING

THIS PRODUCT IS FACTORY SHIPPED FOR USE WITH A 208-230/1/60 ELECTRICAL POWER SUPPLY. THIS AIR HANDLER MUST NOT BE RECONFIGURED TO OPERATE WITH ANY OTHER POWER SUPPLY.

WARNING

WHEN INSTALLING OR SERVICING THIS EQUIPMENT, SAFETY CLOTHING, INCLUDING HAND AND EYE PROTECTION, IS STRONGLY ADVISED. IF INSTALLING THIS EQUIPMENT IN AN AREA THAT HAS SPECIAL SAFETY REQUIREMENTS (HARD HATS ETC.), OBSERVE THESE REQUIREMENTS. TO PROTECT THE UNIT WHEN WELDING CLOSE TO THE PAINTED SURFACES, THE USE OF A QUENCHING CLOTH IS STRONGLY ADVISED TO PREVENT SCORCHING OR MARRING OF THE EQUIPMENT FINISH.

WARNING

THE UNITED STATES ENVIRONMENTAL PROTECTION AGENCY (“EPA”) HAS ISSUED VARIOUS REGULATIONS REGARDING THE INTRODUCTION AND DISPOSAL OF REFRIGERANTS INTRODUCED INTO THIS UNIT. FAILURE TO FOLLOW THESE REGULATIONS MAY HARM THE ENVIRONMENT AND CAN LEAD TO THE IMPOSITION OF SUBSTANTIAL FINES. THESE REGULATIONS MAY VARY DUE TO THE PASSAGE OF LAWS. A CERTIFIED TECHNICIAN MUST PERFORM THE INSTALLATION AND SERVICE OF THIS PRODUCT. SHOULD QUESTIONS ARISE, CONTACT YOUR LOCAL EPA OFFICE.

CARBON MONOXIDE POISONING HAZARD

Special Warning for Installation of Furnace or Air Handling Units in Enclosed Areas such as Garages, Utility Rooms or Parking Areas

Carbon monoxide producing devices (such as an automobile, space heater, gas water heater, etc.) should not be operated in enclosed areas such as unventilated garages, utility rooms or parking areas because of the danger of carbon monoxide (CO) poisoning resulting from the exhaust

emissions. If a furnace or air handler is installed in an enclosed area such as a garage, utility room or parking area and a carbon monoxide producing device is operated therein, there must be adequate, direct outside ventilation.

This ventilation is necessary to avoid the danger of CO poisoning which can occur if a carbon monoxide producing device continues to operate in the enclosed area. Carbon monoxide emissions can be (re)circulated

throughout the structure if the furnace or air handler is operating in any mode.

CO can cause serious illness including permanent brain damage or death.

PRODUCT DESCRIPTION

With the exception of the ARPF024-00B-1, ARPF036-00B- 1, ARPF048-00B-1 and the ARPF060-00B-1 (refered to in this manual as the “B” series), these air handlers are designed to be installed in the upflow, downflow, and horizontal orientations.

The “B” series air handlers are factory configured to be installed in the downflow orientation. DO NOT INSTALL THE “B” SERIES IN THE UPFLOW OR HORIZONTAL POSITION.

The “C” series airhandler is designed for low leak applications. These air handlers are designed for indoor use only and must only be installed in a weatherized area. DO NOT INSTALL OUTDOORS. Typical residential installations for this product include alcoves, basements, attics, crawl spaces, and closets. Other nonresidential applications are acceptable provided they comply with this manual and local/state codes.

When matched with a Goodman or Amana brand condenser or heat pump, an ARI certified rating is available for many combinations.

The AEPT models are equipped with an ECMTM motor. An ECMTM motor is more efficient than a standard PSC motor and offers features such as soft-start, controlled off-delays, and constant CFM. Additional features and the associated controls are discussed later in this manual.

Electric heat is available for all models. This is an accessory and is not provided with the equipment. Use only the electric heat kits identified in the “Electric Heat” section of this manual.

These air handlers are intended for use with a room thermostat. This thermostat is not supplied with this equipment. Only thermostats that use 24 VAC operating voltage can be used.

UNIT INSPECTION

Upon delivery, inspect the unit for damage. Any damage must be reported immediately to the carrier. Do not install this equipment if it is determined that the integrity or safety has been compromised by freight damage.

Using the table “Model Identification” section, check the equipment model number to ensure the unit is appropriately sized for the condenser unit.

If an incorrect unit is supplied, it must not be installed and it is to be returned to the supplier. The manufacturer assumes no responsibility for the installation of incorrectly delivered units.

The evaporator coil contains a high-pressure inert gas holding charge.

ELECTRIC HEAT

WARNING

REFER TO THE “INSTALLING ELECTRIC HEAT” SECTION OF THIS MANUAL AND THE INSTRUCTIONS PROVIDED WITH THE HEAT KIT FOR THE CORRECT INSTALLATION PROCEDURE.

WARNING

THE ELECTRICAL CHARACTERISTICS OF THE AIR HANDLER, THE ELECTRIC HEAT KIT, AND THE SUPPLY POWER MUST AGREE, UNLESS USING HKR3 (3 PHASE) SERIES HEAT KIT. THIS AIR HANDLER DOES NOT HAVE FACTORY INSTALLED ELECTRIC HEAT. ELECTRIC HEAT IS AVAILABLE AS AN ACCESSORY. IF INSTALLING THIS OPTION, THE ONLY HEAT KITS THAT CAN BE USED ARE THE HKR SERIES AS INDICATED BELOW: NOTE: THE AMANA BRAND EHK, ECB, EDB, AND EDK KITS ARE NOT APPROVED FOR USE WITH THESE AIR HANDLERS.

The heating mode temperature rise is dependent upon the system airflow, the supply voltage, and the heat kit size (kW) selected. Use Tables 1-3 to determine the temperature rise (oF).
