The following may be performed by the equipment owner.

Before performing recommended maintenance, be sure unit main
power switch is turned off. Failure to do so may result in electric
shock or injury from rotating fan blade.

CLEANING COILS — Coil should be washed out with wa-

ter or blown out with compressed air. Clean coil annually or as
required by location and outdoor air conditions. Inspect coil monthly
and clean as required. Fins are not continuous through coil sec-
tions. Dirt and debris may pass through first section, become trapped
between the row of fins and restrict outdoor unit airflow. Use a
flashlight to determine if dirt or debris has collected between coil
sections. Clean coil as follows:

1. Turn off unit power and install lockout tag.

2. Using a garden hose or other suitable equipment, flush coil

from the outside to remove dirt. Be sure to flush all dirt and
debris from drain holes in base of unit. Fan motors are
waterproof.

To avoid the possibility of electric shock, before performing any
cleaning and maintenance operations, always turn off power to
the system by pressing the ON/OFF button on the remote con-
trol and turn off the separate disconnect switch located near the
unit.
If the indoor unit is on a separate switch, be sure to turn this
disconnect off as well.

Do not wash filter in water over 120

°

F (to avoid shrinkage). Do

not expose filter to fire (to avoid fire damage). Do not expose
filter to direct sunlight. Clean filter more frequently when air is
extremely dirty.

Do not attempt to clean or service components in controlbox.

To Clean the Indoor Unit Front Panel — if the front panel of the
unit becomes dirty or smudged, wipe the out-side of the panel with
a soft dry cloth. Use a mild liquid deter-gent and wipe off carefully
with a dry cloth.

To Clean Indoor Coil — To clean the coil, remove indoor unit
front panel and vacuum the coil fins, using care not to bend or dam-
age fins.

LUBRICATION — The indoor-fan, automatic air sweep, and the
outdoor-fan motors are factory lubricated and require no oiling.

Operating your system with dirty air filters may damage the in-
door unit and, in addition, can cause reduced perfor-mance, in-
termittent system operation, frost build up on the indoor coil,
and blown fuses. Inspect and clean or replace the air filters
monthly.

TO REMOVE AIR FILTERS — Open the unit's front panel by
lifting the lower part and pulling it gently outward and upward.

Pull out the filters.

TO CLEAN OR REPLACE FILTERS — Filters can be vac-uumed
or washed in warm water. Shake filter to remove any excess water,
and replace it back. If the filter has begun to break down or is torn,
replace it. Replacement filters are available through a local dealer.

The following should be performed by a qualified service techni-
cian.

Clean Condensate Drains — Clean all drains and drain pans at
the start of each cooling season. Check the flow by pouring water
into the drain.

Clean or Replace Drain Pan — The drain pan should only be
cleaned or replaced by a qualified service technician.

1. Place a plastic sheet on the floor to catch any water that may

spill from the drain pan.

2. Remove the intake grille and distribution assembly.

3. Remove the condensate water in the drain pan by letting

water drain into a 3-gallon bucket.
