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. 
 
(Warning! To ensure unit will not interfere with 
drains and refrigerant lines modification must be
