BREEZAIRE WKCE1060 - Manual (Page 5)

WKCE 05/11 PG 5
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 internal delay will be activated and the unit will not restart
for two (2) to three (3) minutes. NOTE: This delay may also occur on initial power-up.
MAINTENANCE
The BREEZAIRE cooling unit requires very little maintenance. To keep the system operating at its top
performance, at least once every three months the condenser coil should be inspected and vacuumed to
prevent air blockage. Remove the large warm air exhaust grille located outside the enclosure where the warm
air is discharged. Use a vacuum with a brush attachment to remove the lint or dirt that may reside between
the aluminum fins. If the condenser coil becomes blocked 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 warm air exterior grille. If it is warm, the unit is working. A further check may be
made by comparing the temperature entering the front grille on the cold side (Evaporator Intake) with that
leaving from the bottom left side (Cold Air Outlet)(see Fig.1). If the air leaving the unit is 6°F or more 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.
In situations where the ambient relative humidity is very low, the desired enclosure relative humidity may not
be achieved without adding moisture. To add moisture to the enclosure only use slow, natural evaporation
from a small porous water container. Do not use a humidifier.
In some cases, improper placement or installation may cause the unit's performance to be degraded. The
warm air exterior side of the unit must have a constant supply of fresh air. If the unit is exhausted into a
confined area with poor ventilation, it will not be able to reject the heat and moisture it is removing from the
enclosure and a malfunctioning unit will be suspected. If an obstruction to the flow of fresh air into or from the
cooling unit (see Fig. 3) is stopped or restricted for any reason the unit could heat rather than cool the
enclosure.
NOTE: Should this condition develop when using the Sentry III, the unit will turn off when the enclosure
temperature rises to approximately 75°F, the unit will not restart until the enclosure temperature is lowered to
approximately 65°F or the unit is disconnected and then re-connected to the power supply. This feature is
disabled for approximately 45 minutes after the unit is connected or re-connected to a power supply.
Proper sealing of the enclosure through the use of a vapor barrier and weather stripping cannot be over
emphasized. The unit will not be able to maintain the proper conditions if fresh, moisture-laden air is
constantly being introduced into an improperly sealed enclosure. Symptoms of this condition are; unit runs all
the time with only a slight reduction in enclosure temperature and/or water overflows from the unit. One way
of discovering gross air leaks is to stand inside the enclosure with the lights off, allow your eyes to adapt to the
dark and look for light showing through cracks in the walls or around the door. Also close the door on a piece
of paper, if you can pull the paper through the door, that means air and moisture are also entering into your
wine cellar. Because of the temperature difference between the inside and outside, very small cracks can
allow large amounts of outside air into the enclosure. Please be aware that moisture will pass through solid
concrete, brick, paint, paper and wood.
