CARE AND MAINTENANCE
The following may be performed by the equipment owner.
Outdoor Units
CLEANING COILS Coil should be washed out with
water 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 sections. 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.
Indoor Units
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 damage fins.
LUBRICATION The indoor-fan, automatic air sweep, and
the outdoor-fan motors are factory lubricated and require no
oiling.
Air Filters for
Indoor Units
TO REMOVE AIR FILTERS
Open the unit's front panel by lifting the lower part and pulling
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.
SERVICE
The following should be performed by a qualified service
technician.
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.
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.
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 control 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 control
box.
Operating your system with dirty air filters may damage
the indoor unit and, in addition, can cause reduced perfor-
mance, intermittent system operation, frost build up on the
indoor coil, and blown fuses. Inspect and clean or replace
the air filters monthly.
it gently outward and upward.
Pull out the filters.
