WARNING

DUCT LEAKS CAN CREATE AN
UNBALANCED SYSTEM AND DRAW
POLLUTANTS SUCH AS DIRT, DUST,
FUMES AND ODORS INTO THE
HOME CAUSING PROPERTY
DAMAGE. FUMES AND ODORS
FROM TOXIC, VOLATILE OR
FLAMMABLE CHEMICALS, AS WELL
AS AUTOMOBILE EXHAUST AND
CARBON MONOXIDE (CO), CAN BE
DRAWN INTO THE LIVING SPACE
THROUGH LEAKING DUCTS AND
UNBALANCED DUCT SYSTEMS
CAUSING PERSONAL INJURY OR
DEATH (SEE FIGURE 1).

• IF AIR-MOVING EQUIPMENT OR
DUCTWORK IS LOCATED IN
GARAGES OR OFF-GARAGE
STORAGE AREAS, ALL JOINTS,
SEAMS, AND OPENINGS IN THE
EQUIPMENT AND DUCT MUST BE
SEALED TO LIMIT THE TOXIC
FUMES AND ODORS, INCLUDING
CARBON MONOXIDE, FROM
MIGRATING INTO THE LIVING
SPACE.

• IF AIR-MOVING EQUIPMENT OR
DUCTWORK IS LOCATED IN
SPACES CONTAINING FUEL
BURNING APPLIANCES, SUCH AS
WATER HEATERS OR BOILERS,
ALL JOINTS, SEAMS, AND
OPENINGS IN THE EQUIPMENT
AND DUCT MUST ALSO BE
SEALED TO PREVENT
DEPRESSURIZATION OF THE
SPACE AND POSSIBLE

With regular maintenance, this hydronic
air handler will operate satisfactorily
year after year. Please read this
manual to familiarize yourself with
operation, routine maintenance
schedule, and safety procedures.

NOTICE

IN COMPLIANCE WITH RECOGNIZED
CODES, IT IS RECOMMENDED THAT
AN AUXILIARY DRAIN PAN BE
INSTALLED UNDER ALL
EVAPORATOR COILS OR UNITS

WARNING

DISCONNECT MAIN ELECTRICAL
POWER TO THE UNIT BEFORE
ATTEMPTING ANY MAINTENANCE.
FAILURE TO DO SO CAN RESULT IN

Do not use this hydronic air handler if
any part has been under water.
Immediately call a qualified installer or
service agency to inspect the hydronic
air handler and to replace any part of
the control system which has been
under water.

ELECTRICAL SHOCK, SEVERE
PERSONAL INJURY OR DEATH.

The blower compartment and motor
should be inspected and cleaned
periodically by your qualified installer,
service agency, or gas supplier to
prevent the possibility of overheating
due to an accumulation of dust and dirt
on the windings or on the motor
exterior. As suggested elsewhere in
these instructions, the air filters should
be kept clean because dirty filters can
restrict airflow and the motor depends
upon sufficient air flowing across and
through it to keep from overheating.

IMPORTANT INFORMATION
ABOUT EFFICIENCY AND
INDOOR AIR QUALITY

Central cooling and heating equipment
is only as efficient as the duct system
that carries the cooled or heated air. To
maintain efficiency, comfort and good
indoor air quality, it is important to have
the proper balance between the air
being supplied to each room and the air
returning to the cooling and heating
equipment.

Proper balance and sealing of the duct
system improves the efficiency of the
heating and air conditioning system and
improves the indoor air quality of the
home by reducing the amount of
airborne pollutants that enter homes
from spaces where the ductwork and or
equipment is located. The manufacturer
and the U.S. Environmental Protection

DO NOT DESTROY. PLEASE READ CAREFULLY AND KEEP IN A SAFE PLACE FOR FUTURE REFERENCE.

Agency’s ENERGY STAR®Program
recommend that central duct systems
be checked by a qualified contractor for
proper balance and sealing.

RECEIVING

Immediately upon receipt, all cartons
and contents should be inspected for
transit damage. Units with damaged
cartons should be opened immediately.
If damage is found, it should be noted
on the delivery papers, and a damage
claim filed with the last carrier.

• After unit has been delivered to job

site, remove carton taking care not to
damage unit.

• Check the unit rating plate for unit
size, voltage, phase, etc. to be sure
equipment matches what is required
for the job specification.

• Read the entire instructions before
starting the installation.

• Some building codes require extra
cabinet insulation and gasketing when
unit is installed in attic applications.

• If installed in an unconditioned space,
apply caulking around the power
wires, control wires, refrigerant tubing
and condensate line where they enter
the cabinet. Seal the power wires on
the inside where they exit conduit
opening. Caulking is required to

prevent air leakage into and
condensate from forming inside the
unit, control box, and on electrical
controls.

Install the unit in such a way as to

•
allow necessary access to the

oil/filter rack and blower/control

c
compartment.

• Install the unit in a level position to
ensure proper condensate drainage.
Make sure unit is level in both

irections within 1/8”.

d

• Install the unit in accordance with any
local code which may apply and the
national codes. Latest editions are
available from: “National Fire

rotection Association, Inc.,

P
Batterymarch Park, Quincy, MA

02269.” These publications are:

• ANSI/NFPA No. 70-(Latest Edition)
National Electrical Code.

• NFPA90A Installation of Air
Conditioning and Ventilating
Systems.

• NFPA90B Installation of warm air
heating and air conditioning systems.

• The equipment has been evaluated in
accordance with the Code of Federal
Regulations, Chapter XX, Part 3280.

SYSTEM OPERATION INFORMATION

1. Keep the air filters clean. Your
heating system will operate more
efficiently, economically and
provide better heating.

2. Arrange your furniture and drapes
so that the supply air registers and
return air grilles are unobstructed.

3. Close doors and windows. This will
reduce the heating load on your
system.

4. Avoid excessive use of exhaust
fans.

5. Do not permit the heat generated
by television, lamps, or radios to
influence the thermostat operation.

6. If you desire to operate your system
with constant air circulation, consult
your thermostat manual or please
ask advice from a qualified installer,
service agency or gas supplier.

During the heating season, the
operation of the hydronic air handler is
automatic. Your qualified installer or
service agency has provided a wall­mounted thermostat which is sensitive
to the change in temperature of the air
moving around the thermostat. Your
thermostat will have switches to select
some or all of the following functions:

HEAT - Turns heating on when
temperature drops below the desired
temperature.

COOL - Turns cooling on when
temperature rises above the desired
temperature.

AUTO - Turns cooling or heating
system on as required to maintain the
desired temperature.

OFF - Turns heating and cooling modes
off. (The blower may still circulate air in
the FAN-ON position.)

FAN-ON - Turns the blower on for
continuous operation.

FAN-AUTO - The blower cycles on and
off with cooling or heating operation.
