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
construction and
contents.
The thermostat is factory set to approximately 55°Fahrenheit. Unless the temperature falls below that which is desired, do
not change the thermostat setting for at least 3 days.
During normal operation the (optional) Sentry III thermostat's 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 can be adjusted no lower than 48°F or higher than 63°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)
Adjustment of mechanical thermostat (WK Model) only requires a small clockwise turn of screw to lower the enclosure
temperature. This screw is located on the front of unit. (See Fig. 1)
(CAUTION) If the operation of the unit is stopped,
either by unplugging it or by turning the thermostat, do not restart it for at lease 10 minutes.
The Sentry III set point (WKL Model), desired enclosure temperature, may be changed by pressing and holding the "SET"
button while momentarily pressing the "COOLER" or "WARMER" button. When the "SET" button is pressed the readout
will automatically change and display the current set point temperature
Should the operation of the cooling unit be interrupted by a power outage or by raising the set point temperature while the
unit is running the Sentry III's internal delay will be activated and the unit will not restart for approximately three (3)
minutes. NOTE: This delay may also occur on initial power-up.
MAINTENANCE
The
BREEZAIRE
cooling unit requires very little maintenance. To maintain optimal performance, the condenser coil
should be inspected and cleaned every 3 months. Remove the exhaust condenser grille located outside the enclosure and
use a vacuum (with brush attachment) to remove dirt and lint from the fins of the condenser coil.
If the condenser coil becomes blocked preventing proper air flow the unit will over heat causing a loss in cooling
efficiency and will result in a failure of the unit not covered under warranty.
ENCLOSURE PROBLEMS
BREEZAIRE
is extremely proud of the quality and reliability of its products. Experience has shown that of the small
number of problems encountered, the large majority are due to improper unit selection or enclosure construction. Should
the cooling system be suspected of malfunctioning, check the temperature of the air being exhausted from the upper part of
the warm air exhaust condenser grille . If it is warm, the unit is working. A further check may be made by comparing the air
temperature entering the lower grille on the cold side (Evaporator side) with that leaving the upper cold side grille. (see Fig.
1) If the air leaving the unit is 6°F or more degrees colder than the temperature entering, the unit is working properly. In
some cases, improper placement or installation may cause the unit's performance to be compromised.
