In some cases, improper placement or installation may cause the unit's performance to be degraded.
The condensing unit
must have a constant supply of fresh air, less than 90o F.
If the condensing unit is located in a confined area with poor
ventilation, the unit will not be able to reject the heat it is removing from the enclosure and a malfunctioning unit will be
suspected. Similar symptoms may be caused by an obstruction to the free flow of air into or out of the condensing unit. In
severe cases of reduced air flow, this unit may over heat and discharge exhaust heat into the fan/coil unit and then into the
enclosure.
Proper sealing of the enclosure through the use of a plastic 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. 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 can
pass through solid concrete, paint and wood.
Often a newly constructed room contains fresh wood, paint, concrete and other building materials. These materials contain
large amounts of moisture. When placed into operation in this type of environment, the system will work harder to remove
this extra moisture resulting in increased "on time".
In areas 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 only slow, natural evaporation from a small water container.
Do not use a humidifier.
