NOTE: Under no circumstances should the roof be con-
structed to create a low spot where water will accumulate
when the air conditioner is installed. This may create a
water leak into the interior of the RV/caravan.

A. LOCATION
The proper location of the thermostat is very important to
insure that it will provide a comfortable RV/caravan tem-
perature. Observe the following general rules when select-
ing a location.
1. Locate the thermostat about 5'/1.4M above the
floor.
Install thermostat on a partition, not on an outside
2.
wall.
NEVER expose it to direct heat from lamps, sun or
3.
other heat producing items.
4.
Avoid locations close to doors that lead outside,
windows or adjoining outside walls.
Avoid locations close to supply registers and the
5.
air from these registers.
6.
Never locate thermostat in a room that is warmer
or cooler than the rest of the RV/caravan -such
as the kitchen.
7.
The major living area is normally a good location.
B. CABLE INSTALLATION
1. A four conductor cable 1 8-24AWG/.25-.75mm
is to be used for low voltage connections.
2. Choose the shortest, direct route from the 14"/
355mm opening to the thermostat location se-
lected.
3. Consider where screws, nails or staples might
contact the cable and avoid inadvertent contact
with cable.
