Condenser Fan Clearances

The top of the condenser fan should be 1−1/2 inches from
the bottom of the top grille. This dimension should be
checked and the fan should be adjusted accordingly any
time servicing of the outdoor fan system is required.

Maintenance

At the start of each cooling season, this equipment should
be serviced by a licensed professional technician (or
equivalent). Periodic inspection and maintenance normally
consists of changing or cleaning filters.

Filters

Not supplied. Inspect once a month. Replace disposable or
clean permanent type as necessary. DO NOT replace per-
manent type with disposable.

Motors

Indoor, outdoor fan and vent motors are permanently
lubricated and require no further lubrication. Motors should
be cleaned yearly to prevent the accumulation of dust and
dirt on the windings or motor exterior.

Coil

Dirt and debris should not be allowed to accumulate on the
coil surfaces or other parts in the air conditioning circuit.
Cleaning should be performed as often as necessary. Use
a brush, vacuum cleaner attachment, or other suitable
means. If water is used to clean the coil, be sure the power
to unit is shut off prior to cleaning.

NOTE − Care should be used when cleaning the coil so that
the coil fins are not damaged.

Do not permit the hot condenser air discharge to be ob-
structed by overhanging structures or shrubs.
