Cooling Operation; Fan Operation; Heating Operation; "Off" Position - Dometic CARAVAN B3200 User Manual

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 2-3 minutes before turning on
the air conditioner. This allows the refrigerant pressures
in the air conditioner system to equalize so the compres-
sor may restart.
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
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.
)
)
(If so equipped)
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.
