In all cases, the equipment MUST be installed in accordance with

the installation instructions described in this manual.

Set the

thermostat to either HEAT or COOL as desired. Set the desired

temperature on your thermostat dial and set the fan switch to

“ON” (for continuous air circulation) or to “AUTOMATIC” (for air

circulation only when the air conditioning system is operating). If

you desire to vary the thermostat temperature setting during the

day for energy conservation (for example, while you are at work). 

IMPORTANT

Wait at least three (3) minutes after turning the

heat pump off before trying to restart. If an attempt is made to

start the compressor before the refrigerant pressures are

equalized, the compressor motor may trip on its overload. An

additional waiting period will be required before restarting.

1. Always install and keep filters clean. Check filters 2 weeks. Clean

or replace if necessary. The factory-installed filter is located

behind the center front access panel.

TO CHANGE SYSTEM FILTER:

A. Turn the power to the unit off at the unit disconnect. The

disconnect is located on the front of the H Series unit behind

a small access door.

B. Remove the front center access door from the unit.
C. Remove and replace the filters with the type and size

indicated in the table below.

D. Replace the access door and turn on the power to the unit.

NOTE:

If your system has a filter grille installed in the return air

opening, the unit filter should have been discarded during

installation. 

The filter installed into the return air grille assembly should be

replaced with the same size and type provided with the grille.
If your system is equipped with a fresh air intake, the filter for the

fresh air assembly is accessed through the front center panel. The

filter is a permanent washable type.

Your equipment is covered by a LIMITED WARRANTY against

defects in material and workmanship. 
This is a vertical wallmount unit designed for many different

applications in both residential and commercial settings. It is self-

contained and arrives completely assembled, factory-charged and

wired. The unit is 100% run-tested at the factory to ensure proper

operation. Your unit is supplied with high-quality copper tubing and

enhanced aluminum-finned coils for high heat transfer efficiency

and long life. The unit cabinet is constructed of G-90 galvanized

steel. All exterior surfaces are finished with a baked-on polyester

coating. This will provide excellent corrosion protection in most

applications. However, if the unit is installed in an area with a

corrosive atmosphere, such as near an industrial plant or on the

seacoast, additional coating should be considered to extend the life

of the coils and cabinet.

This unit was designed for up to 105ºF of ambient temperature for

cooling mode;  for heating mode, this unit was designed for up to 78 ºF

of room temperature, and minimum of 15ºF ambient temperature.

A thorough inspection of the shipping container should be made

immediately upon receiving your unit. Look for any punctures or

openings. If it appears as if damage has occurred, it should be noted

on the freight bill before signing. The delivering carrier should be

contacted immediately to inspect damage, and no installation work

should begin until this inspection is completed.

1. Installation and repair MUST be done by a qualified person.

The equipment should be inspected before use and at least

once annually by a professional service person.

2. AVOID ELECTRICAL SHOCK! Turn power OFF when

servicing. There may be more than one disconnect switch to

de-energize unit.

3.  Close cover(s) before returning breaker(s) to “ON” position.
4. Please observe good safety practices by wearing personal

protective equipment such as gloves and safety glasses to

avoid injury.

5. Installation MUST conform to local codes. In the absence of

local codes, refer to the National Electrical Code (NEC),

ANS/NFPA No. 70-1993 and recommendations made by the

National Board of Fire Underwriters.

In our continuing effort to improve our product, specifications may

change without notice. If there are any questions, please see the
