2. Push up on the ADB at the locations indicated
by the paper labels to engage the snap locks.
There will be a quiet click heard when each latch
engages.
3. Hold the air distribution box to the ceiling with one
hand and install two coarse threaded 3.5 mm X 19
mm sharp pointed screws in the location shown
in FIG. 15. Do not use electric driver as you may
strip the holes in the plastic.
4. Auxiliary screws may be installed at the locations
shown. These are NOT required to secure the ADB
to the template, but may be desired for aesthetic
purposes in some ceiling geometries. See FIG. 15.
Again, do not use an electric driver as you may
over tighten the screws.
5. Filter installation. Slide fi lters into slots in air dis-
tribution box. The outward curved side of the fi lter
handle faces the ceiling. See FIG. 19.
6. Knob installation. Install the two knobs provided
on the ends of the thermostat and selector switch
shafts. Align slot in the knob with the alignment
post on shaft and push into position.
7. The power supply to the unit may now be turned
"ON".
8. Your unit is now installed and ready for operation.
Read the following operating instructions before
attempting to run the unit.
OPERATING INSTRUCTIONS
A. Controls
FIG. 16
Selector Switch
1. The selector switch has ten positions including
"OFF". This controls fan speed, heating mode,
and cooling modes. See FIG. 16.
2. The thermostat controls the compressor ON/OFF
operation for a temperature range from approx.
18.5° C to 32.5° C at the ADB inlet depending on
the knob position. See FIG. 16.
Important:
When the unit is turned on and the ther-
mostat calls for cooling, the compressor will start. After
shutting the unit down manually by either the selec-
tor switch or the thermostat, always wait 2-3 minutes
before turning on the unit. This allows the refrigerant
pressures in the unit system to equalize so the com-
pressor may restart.
Thermostat
B. Cooling Operation (Blue Graphic)
1. Set the thermostat at the desired temperature level.
See FIG. 17.

Cooling
2. Select the fan speed that best satisfi es your
needs:
a. HIGH COOL: Selected when maximum cool-
ing and dehumidifi cation required.
b. MED COOL: Selected when normal or average
cooling required.
c. LOW COOL: Select to maintain room at desired
comfort level. Normally this speed is used for
night time operation.
The compressor will cycle off when the thermostat is satis-
fi ed. The fan runs when the compressor is off to help keep
the temperature uniform throughout the Caravan.
C. Fan Only Operation (Gray Graphic)
1. This will circulate the air in your Caravan without
cooling or heating. There are three positions: HIGH
FAN, MED FAN or LOW FAN to select from, de-
pending upon personal choice. See FIG. 17.
D. Heating Operation (Red Graphic)
Note: The heat mode of operation 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 "HEAT". There are three
positions: HIGH FAN, MED FAN or LOW FAN to
select from , depending upon personal choice. See
FIG. 16.
Use low fan speed with the electric heat strips (use
of higher speeds will make the outlet air feel cool,
but all heating speeds deliver the same watts of
electric heat to the Caravan).
2. The blower will come on immediately. The heat func-
tion will start if the thermostat is not satisfi ed.
3. The element will "cycle off" when the thermostat
is satisfi ed. The fan will continue to run helping
keep the temperature throughout the Caravan
uniform.
E. "OFF" Position (Selector Switch
1. This is to turn unit off.
