Inappropriate locations for the warm air exhaust includes unventilated laundry rooms, closet, bathrooms,
garages, crawl spaces, attics and humid basements.
F
Make sure that the warm air exterior grille can be properly attached to the unit (see Fig. 3).
F
Make a hole through the wall as illustrated in Fig. 2. This unit is to be installed above floor level, 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 additional noise and help reduce condensate
from forming on the underside of the unit.
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.
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 approximately 55 o Fahrenheit. Unless the temperature falls below that desired, do not
change the thermostat setting for at least 3 days.
During normal operation of the (optional) 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
