,IJ Keep air intake filter clean. A dirty filter reduces the efficiency of the system and can cause erratic performance of
controls. It can also result in damage to the heating element and compressor. The unit is provided with a washable
filter that can be cleaned with soap and water. Inspect and clean the filter at least once a month or more often as
conditions dictate. Replace as necessary with a factory approved filter. To replace, slide it up and out through the
front cover immediately in front of the discharge grille opening.
,IJ Do NOT block off outside air flow. Efficient operation of the unit depends on free circulation of air over the indoor and
outdoor coils. Paper, leaves and other debris can reduce efficiency and cause serious damage to the compressor.
,IJ Coils should be inspected periodically for buildup of lint, dirt, leaves, other debris and bent fins. Clean coils with a soft
brush and compressed air or vacuum. Do NOT use sharp objects to clean coils.
,IJ Do NOT operate unit with front panel removed or without filter.
,IJ Ensure that objects such as drapes, furniture, or plants are not blocking free air flow of unit.
,IJ Keep doors and windows closed. Leaving them open will increase the work load on the unit and will result in higher
operating cost and excessive condensate.
,IJ Do NOT operate the unit during construction. Construction dust can clog filter and cause permanent damage to
other components.
,IJ Apply silicon based lubricant to the belt drive system as needed. DO NOT USE ANY SOLVENT BASED LUBRICANTS
SUCH AS WD-40 TM.
Apply silicon-based
lubricant to belt located
inside access door.
