GENERAL iNFORMATiON OVERVIEW Your combination gas heating / electric cooling unit is designed to comfort condition 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 manual 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 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 electrical power to the unit is turned off. until the • Never perform any maintenance procedures until the gas valve in 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 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 maintenance 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 is your responsibility to select a qualified service company that can provide a serviceman 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 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. When the selector switch is positioned at Off your unit will not operate in either heat or cool modes. If the 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. HEAT EXCHANGER COIL DRAIr OUTDOOR COIL BLOWER UNIT CONTROL BOX FLUE BOX FURNACE COM BUSTION FAN BLOWER GAS VALVE PRESSURE SWITCH GENERAL INFORMATION The fan selector switch can be used to operate the indoor fan continuously by positioning it at On. When set at Auto, the 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. AiR FILTERS Filters are to be used with the YC*024-060F heating/cooling units. The basic unit does not have filters in it. However, a filter accessory is offered that will allow filters to be installed in the unit. Otherwise a filter rack must be installed by the installer in the duct work. Affix filter label supplied with the unit adjacent to the filter area.

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 than energizes the heating electrical circuit that starts and controls the furnace burners. Shortly after the burner ignite, the indoor fan starts and circulates warm air through your home. When the air temperature rises to 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 most of the heat is removed from the unit's combustion chamber. SAFETY 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: burner. 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 serviceman. 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 installed. Check to make sure that all the air openings are unobstructed. Never attempt to manually light the 4. Remove the access panel that contains the following label: REMOVE THiS PANEL GAiN j ACCESS TO THE GAS TO VALVE 5. Turn gas control "OFF" either by turning the knob 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 (i.e. caused by dirty air filters or defective fan motor), 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 serviceman for instructions. HEATING Likewise, insure that the spacing around the furnace it self is not blocked or obstructed. clockwise O to the "OFF" position or by moving the toggle switch to "OFF". See Figure 2.

Replace panel removed in Step 3 above. TO TURN OFF GAS TO UNIT CAUTION: If this is done during the cold weather months, provisions must be taken to prevent freeze-up of all water pipes and water receptacles. Whenever 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 failto operate, damage such as frozen water pipes could result. 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 contains the following label: COOLING COOLING SYSTEM OPERATION START-UP AND Once electrical power is supplied to the unit, cooling operation is controlled by the thermostat. With the thermostat selector switch set at COOL, move the cooling adjustment lever to its lowest setting to energizethe unit cooling system. Nowthat the unit is operating, cool air will begin to circulate through your building. Finally, reposition the cooling adjustment lever to the desired room temperature; your unit will continue to operate in the cooling mode automatically. SYSTEM COOLING SYSTEM SHUTDOWN If you wish to shut down the cooling system, the best method is to move the thermostat selector switch to the OFF position. To shut down the unit completely, turn off the main electrical power supply to the unit. Anytime you think the cooling system is not operating properly, shut down unit operation at the thermostat and contact a serviceman for instructions. ROUTINE MAINTENANCE You can do 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.

I 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 at least ever week for the first 4 weeks.) If you have disposable-type filters replace them with 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: Itmay be necessaryto replace permanent filter 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 then 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, dirt, etc. To clean the coil, vertically (i.e., with the fins) stroke the coil surface with a soft-bristled brush.
