B.Cooling Operation
1.Set the thermostat at the desired temperature level.
2.Select the fan speed that best satisfies your needs:
a.HIGH COOL: Selected when maximum cooling and dehumidification required. (3 
)
b.MED COOL: Selected when normal or average cooling required. (2 
)
c.LOW COOL: Selected when room at desired comfort level and needs to be maintained. Normally this speed used for night time opera- tion. (1 
)
Important: When the air conditioner is turned on and the thermostat calls for cooling, the fan and compressor start at the same time. After shutting the air conditioner down manually by either the selector switch or the thermostat, always wait
Note: The blower runs continuously to circulate air and maintain an even temperature. The compressor will come on as cooling is required to maintain the selected temperature level.
C.Fan Operation
1.This will circulate the air in your Caravan without cooling or heating. There are three positions: HIGH FAN (3 
), MED FAN (2 
) or LOW FAN (1 
) to select from, depending upon personal choice. See FIG.15.
D.Heating Operation (If so equipped)
Note: This electric heater will not replace a furnace for heating your Caravan in cold weather. The intent is to remove the chill on cool days or mornings.
1.Turn the selector switch to "OPT HEAT" (
). See FIG. 15.
2.The Heater will come on and begin heating.
3.When desired temperature level in Caravan is reached, move the selector switch to "OFF" or "FAN" position.
Note: Thermostat does not control heater ON/OFF cycle. If the optional heater is not installed and selected, the fan will run as "LOW FAN" operation.
E."OFF" Position
1.This is to turn Unit off.
F.Customer Maintenance
1.Periodically remove the return air filters located above the removable panels in the air box. Wash the filters with soap and warm water, let dry and then reinstall.
Note: Never run the air conditioner without return air filter in place. This may plug the unit evaporator coil with dirt and may substantially affect the performance of the unit.
2.Clean air box housing and control panel with a soft cloth dampened with a mild detergent. Never use furniture polish or scouring powders.
3.The blower motor is factory lubricated and requires no service under normal use.
4.Under certain conditions, frost may form on the evaporator coil. If this should occur, inspect the filter and clean if dirty. Make sure air louvers are not obstructed. Air conditioners have a greater ten- dency to frost when the outside temperature is relatively low. This may be prevented by adjusting the thermostat control knob to a warmer setting (counter clockwise). Should frosting continue, oper- ate on LOW, MED, or HIGH FAN only setting until the cooling coil is free of frost.
5.If your unit fails to operate or operated improperly, check the following before calling your service center.
a.If Caravan connected to motor generator, check to be sure motor generator is running and producing power.
b.If Caravan connected to power supply by a land line, check to be sure line is sized properly to run air conditioner load and it is plugged into power supply.
c.Check your fuse or circuit breaker to see if it is open.
d.After the above checks, call your local service center for further help. This unit must be ser- viced by qualified service personnel only.
6.If any wiring or supply cord is damaged and needs to be replaced, it must be replaced by the manufacturer or its service agent or a similarly qualified person.
7.When calling for service, always give the following:
a.Air Conditioner Model and Serial Number found on rating plate located on base pan of air conditioner bottom.
b.Air Distribution Box Kit Part and Serial Number found on rating plate located on ceiling tem- plate. Observe this rating plate through the air box filter grill opening.
