Quick Start Manual

A. Introduction
Heat Controller, Inc., Air Handlers come in a variety of models and
sizes for upow or horizontal use and when combined with cool-
ing coils, are ready for air conditioning and heat pump applications.
These instructions are primarily to assist qualied individuals trained
and experienced in the proper installation of this type of equipment.
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 efciency.
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 berglass 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, exible 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, ther-
mostat 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 materi-
als 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
lter. Be sure and route primary and secondary drain connections
so as not to obstruct lter replacement.
ARRANGEMENT
Unit is shipped from the factory arranged to be installed in a verti-
cal upow or horizontal right to left airow position (standard) or
eld convertible to a horizontal left to right airow position.
Upow Application
In an upow installation the discharge outlet is at the top. Care
should be taken to ensure unit is level to permit proper condensate
drainage. Normal upow installation will be in a basement or clos-
et. 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 re-
turn air grilles from outside the closet to space below the platform.
Platform must be at least 10” above the oor. Run all supply and
return ductwork in accordance with local codes.
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 lter grille through the ceiling or wall.
Remove lter from unit if lter grill is used. The unit is shipped in
right to left conguration.
FOR LEFT TO RIGHT APPLICATIONS.
1. Remove and set aside front panels.
2. Remove the coil support bracket (4-screws).
CAUTION
A “P” trap must be installed in the coil
drain line! Cap unused drain ttings.
WARNING
To ensure unit will not interfere with drains and
refrigerant lines, modication must be made
prior to installing these lines..
