GENERAL INFORMATION,,

OVERVIEW

Your combination dual fuel heat pump unit is designed to

comfort condition all year long with safe, efficient, trouble-

free operation. It is important that you understand how to

efficiently. This manual will acquaint you with these impor-

tant procedures. Familiarize yourself with this manual and

store it in a convenient location for future reference.
Any additions, changes, or conversions required in order for

the unit to satisfactorily meet the application needs, should
be made by a qualified product distributor or local service
dealer, using factory specified and approved parts. See

figure 1 for component layout.

Remember these instructions at all times:

• Never perform any maintenance procedures until the

electrical power to the unit is turned off.

• Never perform any maintenance procedures until the gas
valve in gas supply line is turned off.

• Never remove any panel from the unit while itis ope rating.

• Never remove panels or parts from the unit that are not
discussed in this manual.

• Never cover the unit since it is designed to operate year
round.

Your unit is of complex design. To ensure that it performs
safely and give long-lasting service, some of the mainte-
nance work must be performed by a qualified serviceman.

When a serviceman is referred to in this manual, it is
describing a service technician that has had special

training or a number of years experience in servicing
this type of equipment. It isyour responsibility to select a

qualified service company that can provide a serviceman of

this caliber.

THERMOSTAT

Room thermostats are delicate temperature-sensing con-
trols. Their main function is to energize and de-energize the
heating orcooling circuit to maintain the temperature setting

you select.
Many thermostats contain a room thermometer to indicate

the approximate room temperature, and atemperature scale
at the adjustment indicator to select the desired indoor air
temperature. In addition, most thermostats have a selector
mode switch with Heat, Off and Cool positions, and a fan

switch with On and Auto positions.

GENERAL INFORMATION

Whenthe selector switch is positioned at Off your unit will not

operate in either heat or cool modes. Ifthe selector switch is
set at heat, the unit will automatically cycle on and off to

maintain the desired temperature settings. The unit will also
operate automatically when the selector switch is positioned

at Cool.

The fan selector switch can be used to operate the indoor fan
continuously by positioning it at On. When set at Auto, the

HEATING SYSTEM

HEATING CYCLE OPERATION

Your unit's heating system has a solid-state electronic
ignition control that lights thefurnace burners each time the
thermostat calls for heat. At the end of each heating cycle,
the furnace burners are extinguished. This type of system is
called Direct Spark Ignition (DSI).

A normal heating cycle begins when the air temperature in
your home drops below the thermostat setting. The thermo-

stat than energizes the heating electrical circuit that starts
and controls the furnace burners. Shortly after the burners

ignite, the indoor fan starts and circulates warm air through
your home.

When the air temperature rises to the thermostat setting, the

thermostatde-energizes the heating electrical circuit, which
in turn, extinguishes the furnace burners. The indoor fan

continues to circulate warm air until most of the heat is
removed from the unit's combustion chamber.

SAFETY CONTROLS

Your unit is equipped with an automatic reset safety limit
Controlto prevent overheating. When this control opens, it
shuts down the heating electrical circuit untilthe unit cools

downsufficiently.Inadequate airflow (i.e. caused by dirtyair
filters or defective fan motor), may cause the unit to cycle on
and off as the limitcontrol tripsand automatically resets. If

you suspect that the unit is cycling on its limit control,
immediately contact a serviceman for instructions.

Ifflames from the burner are notproperly drawn intothe heat
exchanger, a Flame Rollout Protection Control will open
causing the furnace to shut off. The cause must be investi-

gated by a qualifiedserviceman.

HEATING SYSTEM START-UP

Since your unit has an automatic ignition system, it is easy
to start the heating cycle at the beginning of the heating

season.
In order for this unit to operate properly and safely, the

furnace needs air for both combustion and ventilation.
Accordingly, observe the area in which the furnace is in-

stalled. Check to make sure that all the air openings are

unobstructed. Likewise, insure that the spacing around the

furnace it self is not blocked or obstructed.

fan will only operate when required during the heating or
cooling cycles.

To ensure that the thermostat operates properly, it must be

level and positioned to avoid the influence of such external
heat sources as lamps, televisions or other heat-producing
appliances.

1. Set the thermostat's heating adjustment lever at its
lowest setting; then move the selector switch to the Off
position.

2. Turn off all electric power to the unit.

3. This unit is equipped with an ignition device which
automatically lights the burners.

CAUTION: Never attempt to manually light the burner.
