performance. Care must be taken during cleaning to prevent damage to the
coil fins.
Note: Even though the condenser coil is coated to resist deterioration, operation
of this air conditioning unit in areas containing airborne caustics or chemicals can
deteriorate filters and coils. Regular inspection is recommended when operating in
these atmospheres.
Priming of Drain Hose: Not required
Condenser Inlet Filter: Proper maintenance of the inlet filter is required to
assure normal operation of the air conditioner. If filter maintenance is
delayed or ignored, the maximum ambient temperatures under which the
unit is designed to operate will be decreased.
Filter Removal and Installation
Locate the air filter on the side of the air conditioner unit.
Some models require removal of the four screws retaining the filter frame.
A T25 torx driver is required. Other models have a slide-out filter.
Flush the filter with warm soapy water from the exhaust side to the intake
side. Do not use solvents. After flushing, allow filter to drain completely
before re-installing.
Re-install the filter and filter frame.
It is impossible to recommend a filter cleaning interval due to the variety of air
quality conditions. The amount and nature of airborne dust/dirt particles differ per
location. It is recommended that when a fine layer of dust or lint is visible on the
surface of the filter, it be removed and cleaned.
Do not run the air conditioner for extended periods of time with the inlet filter
removed, to minimize dirt buildup on the condenser coils.
