CARE AND MAINTENANCE
Step 1—Maintenance (Outdoor Unit)
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 com-
pressed 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)
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 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.
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.
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
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 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.
