Heat Controller AHG Hydronic Quick Start Manual

Installation, Operation and

Maintenance Manual

A. Introduction

1

Heat Controller, Inc., 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 in the proper installation of this equipment
Refer to local codes

and regulations 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 prevai

ling codes and regulations.
Heat Controller, Inc., assumes no responsibility
fo

r 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. Ductwork 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

ibution duct system should be sized for 0.2

distr

hes of static pressure. See National

inc
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

terior of air handler to comply in these

ex
jurisdictions, putting the vapor barrier on the outside.

HOT WATER CAN SCALD: WATER HEATED

TO A TEMPERATURE WHICH WILL SATISFY

SPACE HEATING, CLOTHES WASHING, DISH

WASHING, AND OTHER SANITIZING NEED

S

CAN SCALD AND PERMANENTLY INJURE A

PERSON UPON CONTACT.

10. Some people are more likely to be permanently
injured by hot water. These include the elderly,
children, the infirm, or physically handicapped. If

yone using hot water in a home fits into one of

an
these groups, or if there is a local code or state law
requiring certain maximum temperature water at the
hot water tap, then special precautio

ns must be taken
in addition to using the lowest possible temperature
setting that satisfies hot water needs, some type of
tempering device, such as a mixing valve, must be
used to ensure that people who might be adversely

fected are not subjected to harmful water

af
temperatures..

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 shipping carrier. This
is the responsibility of the entity receiving the equipment. The
air handler is completely assembled, as received. Electric
power, thermostat wiring, water piping, refrigerant piping and
duct connections are needed to c

omplete an installation.
Additionally, drain connections will be needed.
Ch

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