GENERAL INFORMATION
A. Frost Formation On Cooling Coil
Frost on a small portion of the coil is not un usual. Under
certain conditions, ice may form on the evaporator coil. This
is indicated by very cold output at very low air speed and
the icing can be seen through the air inlet hole with the lter
removed. If this should occur, inspect the lter and clean
if dirty. Make sure air vents are open and not obstructed.
Units have a greater tendency to frost when the outside
temperature is relatively low. This may be prevented by
ad justing the thermostat control knob to a warmer setting
(counter clockwise). Should frosting con tinue, operate on
any FAN ONLY setting until the cooling coil is free of frost;
then resume nor mal operation. If frost condition persist,
contact your local service center for assistance.
B. Condensation
The manufacturer of this unit will not be responsible for
damage caused by condensation forming on ceilings,
windows, or other surfaces. Air contains water vapor which
condenses when temperature of a surface is below Dew
point. During normal operation this unit is designed to
remove a certain amount of moisture from the air, depend-
ing on the size of the space being conditioned. Keeping
doors and windows closed when this air conditioner is in
operation will greatly reduce the chance of condensation
forming on interior surfaces.
C. Air Distribution
Each A/C unit operating in cool mode, must have a mini-
mum of 2 distribution vents, or the quick cool vent and one
vent open, to avoid the risk of freezing coils and improper
function.
