HOME OWNER’S INFORMATION

Split System Heat Pump

THERMOSTAT

Your Heat Pump is controlled by the thermostat mounted on

your wall. The thermostat is a highly sensitive low voltage

device and is available in several different configurations from

different manufacturers. The details listed below are typical for

most installations. Ask your dealer for more specific

information regarding the model of thermostat installed.

Heating Mode

Set the system selector switch to HEAT. The heat pump will

run until the actual room temperature is raised to the point

you have selected.

NOTE:

you may see

steam

(looks like “

smoke

”) coming

from the outdoor unit during cold weather. This is normal as

frost is removed from the coil during the defrost cycle.

Cooling Mode

Set the system selector switch to COOL. The heat pump will

run (as an air conditioner) until the actual room temperature

is lowered to the point you have selected.

Temperature Control

Set the temperature selector to your desired room

temperature. For heating, the heat pump will run any time

the actual room temperature falls below the point you have

selected. For cooling, the heat pump will run (as an air

conditioner) any time the actual room temperature rises

above the point you have selected.

Fan Control

The fan selector switch allows you to run the fan

continuously or cycle it automatically with the heating or

cooling system. Set the selector switch to ON for continuous

operation or to AUTO for automatic cycling. For maximum

comfort satisfaction, continuous fan operation throughout

the year is recommended (selector switch set to ON).

WHAT TO DO IF YOUR SYSTEM DOES

NOT WORK

Before Requesting a Service Call:

1. Check thermostat settings. If you desire heat, make sure

to select a temperature above the actual room

temperature, and set the system selector switch to

HEAT. If you desire cooling, make sure to select a

temperature below the actual room temperature, and set

the system selector switch to COOL.

2. Inspect your return air filter. Replace a dirty filter or clean

a reusable type filter.

3. Check circuit breakers and/or fuses. Reset breakers or

replace fuses as necessary.

4. Inspect the coils and fins on the outdoor unit. Clean away

any obstructions (grass clippings, leaves, dirt, dust, or

lint). Check that branches, twigs, or other debris are not

obstructing the fan blade.

If your system still does not operate, contact

your servicing dealer.

Have the Model and Serial Numbers of the indoor and

outdoor units available and be sure to describe the problem.

REGULAR MAINTENANCE

REQUIREMENTS

Your system should be regularly inspected by a qualified

service technician. Between visits, there are some routine

maintenance procedures you can do to help keep your

system operating at peak performance.

WARNING

ELECTRICAL SHOCK HAZARD
Failure to turn off electrical power could result in per-

sonal injury or death.
Turn OFF all electrical power to both the indoor and

outdoor units before performing any maintenance or

removing any panels or doors. There may be more

than one electrical disconnect switch.

Air Filter

Inspect air filters at least monthly and replace or clean as

required. Disposable type filters should be replaced.

Reusable type filters may be cleaned by soaking in mild

detergent and rinsing with cold water. Install filters with the

arrows on the side pointing in the direction of air flow.

Dirty air filters are the most common cause of

inadequate heating or cooling performance, and of

compressor failures.

Condensate Drain

The indoor coil condenses water from the air, and this water

must be disposed through an appropriate drain system.

During the cooling season check at least monthly for free

flow of drainage and clean if necessary.

Outdoor Unit Coils

Grass clippings, leaves, dirt, dust, lint from clothes dryers,

and fall

−

off from trees can be drawn into coils by movement

of the air. Clogged outdoor coils will lower the efficiency of

your unit and could cause damage to the compressor. Clean

debris away from the outdoor coils.
Use a soft bristle brush with light pressure only. Do not

damage or bend coil fins. Damaged or bent fins may affect

unit operation.

Painted Surfaces

In geographical areas where the water has a high

concentration of minerals (calcium, iron, sulfur, etc.) it is

recommended that lawn sprinklers not be allowed to spray

on the unit. Spraying this type of water on the unit may result

in premature deterioration of the paint finish and metal

components.
Never use a weather cover over the outdoor unit unless it is

a ventilated type or made of breathable fabric that will allow

moisture to evaporate rapidly. A cover that holds moisture

in the unit will cause more rust build

−

up and damage than

normal exposure to weather.
