Overview

Your combination gas heating/electric cooling unit is designed to provide comfort all year long with safe, efficient, trouble-free operation. It is important that you understand how to operate and maintain your unit to keep it operating safely and efficiently. This guide will acquaint you with these important 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 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 the gas supply line is turned off.

◆ Never remove any panel from the unit while it is operating.

◆ Never remove panels or parts from the unit that are not discussed in this guide.

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

◆ Never store anything flammable or combustible around or near the unit.

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

When a service technician 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 is your responsibility to select a

qualified service company that can provide a service technician of this caliber.

Thermostat

Room thermostats are delicate temperature-sensing controls. Their main function is to energize and de-energize the heating or cooling circuit to maintain the temperature setting you select.

Many thermostats contain a room thermometer to indicate the approximate room temperature, and a temperature scale to select the desired indoor air temperature. In addition, most thermostats have modes of HEAT, OFF and COOL, and fan modes of ON and AUTO.

When OFF is selected your unit will not operate in either heat or cool modes. If HEAT or COOL is selected, the unit will automatically cycle on and off to maintain the desired temperature settings.

When AUTO is selected, the fan will only operate as required during the heating or cooling cycles. The fan mode can be used to operate the indoor fan continuously by selecting ON. Con- tinuous fan mode during cooling operation may not be appropriate in humid climates. If the indoor air exceeds 60% relative humidity or simply feels uncomfortably humid, it is recommended that the fan only be used in the AUTO mode.

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.

Two Stage Cooling Models --For units with the feature of two staged cooling, the thermostat will determine whether to run the system at the full capacity or a lower capacity. This depends on the daily cooling load of the conditioned space. The system is more efficient when running at low capacity (1 will be sufficent to maintain indoor comfort.

With the thermostat set to COOL, the system will automatically cycle on and off as well as from low (1st stage) to high (2 point for indoor comfort.

To Start the Heating System

Heating Cycle Operation

Your unit's heating system has a solid-state electronic ignition control that lights the furnace 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 thermostat then 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 above the thermostat setting, the thermostat de-energizes the heating electrical circuit, which in turn, extinguishes the furnace burners. The indoor fan continues to circulate warm air until the remaining heat is removed from the unit's heat exchanger.

Safety Controls

Your unit is equipped with an automatic reset safety limit control to prevent overheating. When this control opens, it shuts down the heating electrical circuit until the unit cools down sufficiently. Inadequate airflow may cause the unit to cycle on and off as the limit control trips and automatically resets. If you suspect that the unit is cycling on its limit control, immediately contact a service technician for instructions.

If the unit is unable to exhaust combustion by-products properly, due to a blocked flue hood or other blockage, a pressure switch safety device will prohibit the unit from operating. The cause must be investigated by a qualified service technician.

If flames from the burner are not properly drawn into the heat exchanger, a Flame Rollout Protection Control will open causing the furnace to shut off. The cause must be investigated by a qualified service technician.

Heating System Start Up

CAUTION

▲

Never attempt to manually light the burner. This unit is equipped with an ignition device which automatically lights the burners.

3. Remove the access panel that is identified as CONTROL/ HEAT.

4. Turn gas control off by moving the toggle switch to OFF. See Figure 2 on page 5.

5. Wait five (5) minutes to clear any gas. If you then smell gas, STOP!, for your safety follow the “What To Do If You Smell Gas” instructions on the front page. If you do not smell gas, go to next step.

6. Turn gas on by moving the toggle switch to ON.

7. Replace the panel that you removed in Step 3 and make sure all other unit panels are securely in place.

8. Turn on all electrical power to the unit.

9. Set thermostat to desired temperature and the fan to ON. The unit will now operate automatically.

10.If the unit will not operate, perform the steps in the following section, "To Turn Off Gas To Unit" (under Heating System Shutdown) and call your service technician or gas supplier.

NOTE: The unit is to be adjusted to obtain a temp air rise that is specified on the nameplate.

Heating System Shutdown

To shut down the heating system for brief periods of time, simply adjust the thermostat selector switch to the OFF position.

If you need to turn the gas off to the unit, follow the steps below:

To Turn Off Gas To Unit

1. Set the thermostat to lowest setting.

2. Turn off all electric power to the unit if service is to be

performed.

3. Remove the access panel that is identified as CONTROL/

HEAT.

4. Turn gas control off by moving the toggle switch to OFF.

See Figure 2 on page 5.

5. Replace the panel you removed in Step 3.

Your unit has an automatic ignition system. This feature makes it 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 installed. Check to make sure that all the air openings are unobstructed. Likewise, insure that the spacing around the furnace itself is not blocked or obstructed.

1. Set the thermostat to lowest setting.

2. Turn off all electric power to the unit if service is to be performed.

CAUTION

▲

If you shutdown your heating system during the cold weather months, precautions must be taken to prevent freeze-up of all water pipes and water receptacles. When-

ever your home or building is to be vacant, arrange to have someone inspect your structure for proper temperature. This is very important in below freezing weather. If for any reason your furnace should fail to operate, damage such as frozen water pipes could result.

Regular Owner Maintenance

CAUTION

▲

Never use combustible cleaning fluids on any part of the furnace.

You can perform some of the periodic maintenance functions for the unit yourself; this includes replacing (disposable) or cleaning (permanent) the air filters, cleaning the cabinet, cleaning the condenser coil, and conducting a general unit inspection on a regular basis.

Air Filters

It is very important to keep the central duct system air filters clean. Be sure to inspect them at least once each month when the system is in constant operation (in new homes, check the filters weekly for the first 4 weeks).

If you have a disposable-type filter replace it with a new filter of the same type and size. DO NOT ATTEMPT TO CLEAN DISPOSABLE FILTERS.

Permanent-type filters can be cleaned by washing them with a mild detergent and water. Make sure that the filters are thoroughly dry before reinstalling them in the unit (or duct system).

Note: It may be necessary to replace permanent filters annually if washing fails to clean the filter, or if the filter shows signs of deterioration. Be sure to use the same type and size as was originally installed.

Unit Cabinet

Even though the unit cabinet is designed to withstand exposure to outdoor weather, you can extend the life of the cabinet panel by cleaning and waxing it twice each year. Application of a light coat of automobile wax is recommended.

Condenser Coil

Unfiltered air circulates through the units condenser coil and can cause the coil's surface to become clogged with dust and dirt. Have the coils checked by a service technician each cooling season.

Be sure to keep all vegetation away from the condenser coil area.

General Unit Inspection

Occasionally check over the unit; look and listen for unusual or abnormal operating characteristics. Do not remove any access panels. If you suspect your unit is not operating properly, contact a service technician for instructions.
