warm air exhaust includes unventilated small rooms, closets, bathrooms, hot garages, unventilated crawl
spaces, attics and humid basements.
Make sure that the warm air exterior grille can be properly attached to the unit (see Fig. 3).
Make a hole through the wall as illustrated in Fig. 2. Construct a shelf as shown in Fig. 3. This shelf
must be capable of supporting the weight indicated in the specifications. NOTE: Insulation placed
between the unit and the shelf will reduce noise and help reduce condensate from forming on the
underside of the unit.
If your installation cannot be performed in accordance with these instructions contact your
dealer.
Place the unit through the opening with the exhaust side flush to the outside wall. Attach the warm side
exterior grille (Fig. 1&3) to unit and wall with screws supplied. Please remember that in
all
cases the exterior
grille must be directly attached to the warm side of the unit.
Do not
leave an air gap between the unit's
surface and the exterior grille.
The unit will
not
work properly without this grille.
The warm side exterior
grille has only a white primer coat. If the grille is installed on an outside wall it should be coated with an
appropriate paint to prevent rust.
OPERATION
On initial start-up the cooling unit will reduce the temperature of the enclosure slowly. The unit may run
constantly or cycle off for short periods. The time required to reach the desired temperature will vary,
depending on the enclosure's construction and contents.
The thermostat is factory set to 55o Fahrenheit. Unless the temperature falls below that desired, do not
change the thermostat setting for at least 3 days.
During normal operation of the Sentry III thermostat the LED readout will display the temperature of the air
entering the intake of the cooling unit. If the optional bottle probe is installed the intake air sensor will be
disconnected and the temperature of the probe will be displayed. The temperature being displayed is also the
temperature used by the control system to turn the cooling unit on and off.
After initial cool down, the "on-off" cycle should be relatively constant. The percentage of "off " time will
depend on enclosure's construction, placement of unit, contents, and surrounding outside temperatures. If it
is necessary to adjust the temperature of the enclosure; adjust the thermostat to a colder temperature while
the unit is running and to a warmer temperature while the unit is off. The set point may be set no lower than
48°F or higher than 62°F. NOTE: If the enclosure is not cooling to the current set point, lowering the set point
temperature further will not help. (See ENCLOSURE PROBLEMS section)
The Sentry III set point (desired enclosure temperature) may be changed by pressing and holding the "SET"
button while pressing the "COOLER" or "WARMER" button. When the "SET" button is pressed the readout
will automatically change and display the current set point temperature
