MAINTENANCE
The
BREEZAIRE
cooling unit requires very little maintenance. To maintain optimal performance,
the condenser coil should be inspected and cleaned every three months use a vacuum (with
brush atachment) to remove dirt and lint from the inlet 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 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, that the large majority are due to improper unit
selection or enclosure construction. In some cases, improper placement or installation may cause
the unit's performance to be compromised. Should the cooling system be suspected of
malfunctioning, check the temperature of the air being exhausted from the upper part of the
exterior condenser's grille. If it is warm, the unit is working. A further check may be made by
comparing the air temperature entering the lower grill on the cold side (fan/coil unit) with that
leaving the upper smaller grille. If the air leaving the unit is at least 6oF ore colder than the
temperature entering, the unit is working properly.
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 use
slow, natural evaporation from a small unglazed clay water container. Do not use a humidifier.
Improper placement or installation may cause the unit's performance to be degraded. If the
condensing unit is located in a confined area with poor ventilation or duct work, 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 the flow of fresh air to or from the exterior condensing unit is stopped or restricted for
any reason the unit could heat rather than cool the enclosure.
Proper sealing of the enclosure through the use of a vapor barrier and weather stripping cannot be
over emphasized. The cooling system 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 seal, it means air and moisture are also entering into your enclosure.
Because of the temperature difference between the inside and outside, very small cracks can
allow large amounts of outside air into the enclosure. Please beware that moisture will pass
through solid concrete, brick, paint, paper and wood. A newly constructed room may contain fresh
wood, paint, concrete and other building materials containing large amounts of moisture. This
condition can cause symptoms similar to a poorly sealed enclosure, but will gradually go away.
