40 CG, CS CARE AND MAINTENANCE
Step 1 – Maintenance (Outdoor Unit)
WARNING
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 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.
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.
Step 2 – Maintenance (Indoor Unit)
CAUTION
To avoid the possibility of electric shock, before
performing any cleaning and maintenance
operations, always turn off power to the system
by pressing the mode button on the remote
control unit until the display shows “OFF,” 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.
CAUTION
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.
CAUTION
Do not attempt to clean or service components in
control box.
LUBRICATION
The indoor-fan, automatic air sweep, and the outdoor-
fan motors are factory lubricated and require no oiling.
TO REMOVE AND CLEAN OR REPLACE AIR
FILTERS
CAUTION
Operating your system with dirty air filters may
damage the indoor unit and, in addition, can
cause reduced performance, intermittent 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
Remove filters by pulling them straight out.
To Clean Or Replace Filters
Filters can be vacuumed or washed in warm water.
Shake filter to remove any excess water, and replace
by sliding filter behind grille until filter snaps in place.
If the filter has begun to break down or is torn, replace
it. Replacement filters are available through your
Carrier distributor.
To Clean Indoor Unit Bottom/Front Panel
If the bottom/front panel of the unit becomes dirty or
smudged, wipe the outside of the panel with a soft dry
cloth. Use a mild liquid detergent and wipe off
carefully with a dry cloth.
To Clean Indoor Coil
To clean the coil, remove indoor unit bottom/front
panel and vacuum the coil fins, using care not to bend
or damage fins.
To 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.
To Clean Or Replace Drain Pan
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.
