A. Introduction

Heat Controller Air Handlers come in a variety of
models and sizes for upflow or horizontal use and
when combined with cooling coils, are ready for air
conditioning and heat pump applications.
These instructions are primarily to assist qualified
individuals trained and experienced in the proper
installation of this type of equipment. Refer to
authorities having jurisdiction for additional
guidance.

B. Rules for Safe Installation and Operation

1. Read these rules and the instructions carefully.
Failure to follow the rules and the instructions could
cause a malfunction of the unit, and a possible safety
hazard. Keep these instructions nearby the unit for
future reference.

2. This unit has been designed and manufactured
to comply with National Codes; however, it is the
installer’s responsibility to install this unit to comply
with prevailing codes and regulations. Heat
Controller, Inc assumes no responsibility for units
installed in violation of any code or regulation.

3. Before servicing, ALWAYS SHUT OFF
ELECTRICITY TO THE UNIT. This will prevent
any electrical shocks.

4. Ground the unit to prevent electric shock. All
electrical wiring should be in accordance with the
National Electrical Code.

5. Duct work must be installed in accordance
with the standards of the National Fire Protection
Association (NFPA) for the installation of Air
Conditioning, Warm Air Heating and Ventilating
Systems (NFPA 90A and 90B). The air distribution
duct system should be sized for 0.2 inches of static
pressure. See National Environmental Systems
Contractors Association Manual K for duct sizing
recommendations. Ductwork in non-conditioned
spaces must be insulated to prevent formation of
condensate and for maximum operating efficiency.

6. The safety testing agency label appearing on
the unit covers the unit and factory installed coil(s)
only. It does not cover any other equipment.

7. Exterior surface of cabinet may sweat when
unit is installed in non-conditioned space such as
attic or garage. Installer

must provide protection such

as full size auxiliary drain pan on all units installed in
non-conditioned space such as attic or garage type
installations to prevent damage from condensation. It
is recommended that units installed in non
conditioned space be insulated on the outside with 1”
thick fiberglass with the vapor barrier on the outside.

8. While designed to operate quietly when
properly installed, several steps should be taken to
insure this. Use of isolation pads when mounting
unit, flexible duct collars for discharge, and use of
acoustical duct liners are all good installation
practices that promote quiet operation.

9. Cabinet insulation is rated for R=4.2 (standard).
Some jurisdictions require R=6.0 on installations in
non-conditioned space. Add insulation 1” thick to
exterior of air handler to comply in these
jurisdictions, putting the vapor barrier on the outside.

C. Unpacking the Unit

The unit should be unpacked on receipt and if
damage is found, a claim should be made
immediately to the shipping carrier. This is the
responsibility of the entity receiving the equipment.
The air handler is completely assembled, as received.
Electric power, thermostat wiring, refrigerant piping
and duct connections are needed to complete an
installation. Additionally, a drain connection will be
needed.
Check the rating plate for unit size, voltage, phase
etc. to make sure unit meets your requirements.

D. Physical Installation
MINIMUM CLEARANCES

These units have a 0” minimum clearance to
combustible materials rating from all cabinet
surfaces. The unit should be installed with
serviceability clearance of 30” from the front of the
unit. The unit can be serviced entirely from the front,
including replacing the filter. Be sure and route

primary and secondary drain connections so as
not to obstruct filter replacement.
ARRANGEMENT

Unit is shipped from the factory arranged to be
installed in a vertical upflow or horizontal right to
left airflow position (standard) or field convertible to
a horizontal left to right airflow position.

Upflow Application

In an upflow installation the discharge outlet is at
the top. Care should be taken to ensure unit is level
to permit proper condensate drainage. Normal
upflow installation will be in a basement or closet. If
installed in a closet, the closet should have a platform
framed in, with an opening on top of the platform
centered in the closet. Connect the supply air outlet
to a discharge air plenum. Install return air grilles
from outside the closet to space below the platform.
Platform must be at least 10” above the floor. Run all
supply and return ductwork in accordance with local
codes.
Caution!! A “P” trap must be installed in the coil
drain line! Cap unused drain fittings.

Horizontal application

Horizontal application will normally be used in an
attic or crawl space. This type installation requires a
return air duct be attached to the air handler inlet.
The opposite end of the return air duct is attached to
a return air filter grill through the ceiling or wall.
Remove filter from unit if filter grill is used. The
unit is shipped in right to left configuration.

drains and refrigerant lines modification must be
