maximum heat and allow the system to reach steady state conditions. Insert two thermometers, one in the return air and one in the supply air. The temperature rise is the supply air temperature minus the room air temperature.

Use HKR specification sheets to determine the HKR available for a given air handler.

HKR INSTALLATION

Follow instructions listed in Installation and Operating Instructions shipped with the heat kit.

LOCATION

WARNING

THIS AIR HANDLER IS DESIGNED FOR INDOOR INSTALLATION ONLY. DO NOT INSTALL OUTDOORS.

When installing this air handler consideration to minimize the length of refrigerant tubing is to be given. Do not install the air handler in a location either above or below the condenser that violates the instructions provided with the condenser. The clearance from a combustible surface to the unit is 0". However, service clearance is to take precedence. Allow a minimum of 24" in front of the unit for service clearance. When installing in an area directly over a finished ceiling (such as an attic), an emergency drain pan is required directly under the unit. See local and state codes for additional requirements. When installing this unit in an area that may become wet, elevate the unit with a sturdy, non-porous material. In installations that may lead to physical damage (i.e. a garage) it is advised to install a protective barrier to prevent such damage.

DUCTWORK

This air handler is designed for a complete supply and return ductwork system.

CAUTION

DO NOT OPERATE THIS PRODUCT WITHOUT ALL DUCTWORK ATTACHED.

To ensure correct system performance, the ductwork is to be sized to accommodate 375-425 CFM per ton of cooling with the static pressure not to exceed .5" WC. Inadequate ductwork that restricts airflow can result in improper performance and compressor or heater failure. Ductwork is to be constructed in a manner that limits restrictions and maintains suitable air velocity. Ductwork is to be sealed to the unit in a manner that will prevent leakage.

Return Ductwork. DO NOT TERMINATE THE RETURN DUCTWORK IN AN AREA THAT CAN INTRODUCE TOXIC, OR OBJECTIONABLE FUMES/ODORS INTO THE DUCTWORK. The return ductwork is to be introduced into the air handler bottom (upflow configuration).

Return Air Filters. Each installation must include a return air filter. This filtering may be performed at the air handler or externally such as a return air filter grille. Air handlers mounted in the downflow orientation, including “B” series,

require external filtering. A washable filter is available as an accessory. To ensure optimum performance frequent filtercleaning is advised.RefertoTable 5 for the appropriate filter.

WARNING

TO AVOID THE RISK OF FIRE OR EQUIPMENT DAMAGE, USE ONLY COPPER CONDUCTORS. BEFORE SERVICING OR INSTALLING THIS EQUIPMENT, THE ELECTRICAL POWER TO THIS UNIT MUST BE IN THE “OFF” POSITION AND ALL POWER SUPPLIES DISCONNECTED.

CAUTION

MORE THAN ONE DISCONNECT MAY EXIST. FAILURE TO OBSERVE THIS WARNING MAY RESULT IN AN ELECTRICAL SHOCK THAT CAN CAUSE 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 AND CONTROL BOX WIRE TO THE BUILDING’S 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 OR DEATH.

Inspection of the Building Electrical Service

This unit is designed for single-phase electrical supply. DO NOT OPERATE ON A THREE-PHASE POWER SUPPLY. Measure the power supply to the unit. The supply voltage must be in agreement with the unit nameplate power requirements and within the range shown in Table 6.

Nominal Input	Minimum Voltage	Maximum Voltage
208/230	187	253
