Air Cooled Units
The models 150 and 152 require a minimum of 6” (152
mm) of clearance around both sides. Install the skirt
provided on the right side of the unit and place the back
of the unit against a wall to prevent recirculation of
warm air. The model 162 requires 6” (152 mm) on all
sides and the skirt installed on the rear of the unit. The
model 168 requires 3” (76 mm) on all sides and the
skirt installed on the rear of the unit. Minimum air
clearances must be met to assure adequate air flow for
optimum performance.
These units are designed for indoor use only.
DO NOT
install the units in an area where a
water jet could be used. Failure to follow this
instruction may result in serious electrical shock.
