Electric Heat; Hkr Installation; Location - Goodman ARUF Series Installation & Operating Instructions Manual

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.

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 ( o F).

Note: For installations not indicated above the following
formula is to be used:
TR = (kW x 3412) x (Voltage Correction) x 1.08 / CFM
Where: TR

NOTE: The Temperature Rise Tables can also be used to
determine the air handler airflow delivery. When using these
tables for this purpose set the room thermostat to 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.

WARNING
AIR HANDLERS ARE DESIGNED FOR INDOOR
INSTALLATION ONLY. DO NOT INSTALL OUTDOORS.
Consideration to minimize the length of refrigerant tubing
must be given when installing Air Handlers. Do not install
21
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
59
precedence. Allow a minimum of 24" in front of the unit for
51
service clearance. When installing in an area directly over
44
a finished ceiling (such as an attic), an emergency drain
39
pan is required directly under the unit. See local and state
35
codes for additional requirements. When installing this unit
in an area that may become wet, elevate the unit with a
