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,
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
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.
