2. The thermostat controls the compressor On/
OFF operation within a temperature range of
approximately 65° F and 90° F measured at the
ADB inlet.
B. "OFF" Position ( )
1. This is to turn unit off.
C. Cooling Operation (Blue Graphic)
1. Turn selector switch to cooling (blue graphic).
2. Set the thermostat at the desired temperature
level.
3.
Select the fan speed that best satisfies your
needs:
a. HIGH COOL: Selected when maximum cool-
ing and dehumidification required.
b. MEDIUM COOL: Selected when normal or
average cooling required.
c. LOW COOL: Selected when room is at de-
sired comfort level and needs to be main-
tained. Normally this speed used for night
time operation.
The compressor will cycle on and off as
cooling is required to maintain the select-
ed temperature level. The fan runs when
the compressor is off to help keep the
temperature uniform throughout the boat.
Wait at least 2 minutes before
restarting the compressor when it has been
manually cycled off with either the selector
switch or the temperature set lever. Other-
wise, compressor will quick-cycle and could
result in compressor or supply circuit over-
load.
D. Heating Operation (With Electric Heater
Option Installed).
The heat mode of operation will
NOT
replace
a furnace for heating your boat in cold weath-
er. The intent is to remove the chill on cool
days or mornings.
1. Turn the selector switch to
"OPT HEAT"
.
2. The heat strip will come on and begin heating.
3. When desired temperature level in boat is
reached, move the selector switch to
"OFF"
po-
sition or
"FAN"
position.
Thermostat does
NOT
control the fan/heater
ON/OFF cycle.
