TIMER MODE — Your Carrier Air Conditioner
unit can be programmed so that the unit will shut off
after a certain number of hours (if operating) or turn
on after a certain number of hours (if off).
Press the Timer button to start the Timer mode. The
number of hours will start at 0. The range is 0 to
24 hours.
If the unit is operating, the number of hours until the
unit will turn off will be displayed. If the unit is off,
the number of hours until the unit will turn on will be
displayed. Use the UP and DOWN ARROW buttons to
change the number of hours.
Press the Timer button again to cancel Timer mode.
EXHAUST AIR LEVER — The 73KCA081 units
are equipped with an exhaust air lever. When the
lever is pushed in, the air conditioner will circulate
room air only. When the lever is pulled out, the air
conditioner will exhaust some room air to the outside.

ENERGY SAVING TIPS

Your Carrier air conditioner is designed to operate
efficiently and save on energy costs. Follow these rec-
ommendations for even greater energy savings.
• Select the warmest thermostat setting that will suit
your comfort needs and leave the thermostat at that
setting.
• Keep the air filter clean (clean approximately every
30 days).
• Use drapes, curtains, or shades to keep direct sun-
light from heating the room.
• Do not obstruct the front panel air intake. Do not
obstruct the top air discharge. Allow air to circulate
freely around the air conditioner.
• Start your air conditioner before outdoor tempera-
ture, cooking heat, or groups of people make the
room hot and uncomfortable. This avoids an initial
period of discomfort while the air conditioner is cool-
ing the room.
• When outdoor temperature is cool enough, use the
Fan Only setting. This circulates indoor air, pro-
vides comfort, and utilizes less electricity than
when operating in cooling modes.

MAINTENANCE

When servicing the air conditioner, make sure the
mode is set to OFF and the unit is unplugged from the
electrical outlet.

CLEAN FILTER

Normally, the air filter should be cleaned every
30 days. The filter is highly efficient in removing
airborne particles. More frequent cleaning may be
required in areas with low outdoor and indoor air
quality.
To remove the filter, grasp the filter handle tabs on
the top center of the front inlet grille and slide the fil-
ter out to the top. The filter may be vacuumed or
washed by hand in warm water. Use of a mild deter-
gent is recommended. Dry the filter thoroughly after
washing. Replace the air filter by sliding it back into
the filter slot. Do not operate the unit without the
filter.

CLEAN FRONT PANEL

The front panel may be cleaned after it is removed
from the air conditioner. Wash the grille by hand with
warm water and a mild soap. Be sure to thoroughly
dry the grille before reinstalling. Never pour water
directly on the unit. Do not use gasoline, thinner, or
other chemicals to clean unit.

CLEAN BASEPAN

The basepan may need to be cleaned if there is a
build-up of mold, mildew or algae that could cause
unpleasant odors. When outdoor humidity is high, con-
densate may not fully evaporate from basepan during
normal operation. To clean the basepan, run the air
conditioner in Fan Only mode for 4 to 6 hours to
remove condensate. Remove the front panel. Use
bleach or other cleaner to remove mold, mildew, or
algae from basepan. Replace front panel.

CARE OF THE REMOTE CONTROL

The remote control should last indefinitely with proper
care. Do not expose the remote control to direct heat.
Do not spill liquids or place heavy objects on the
remote control. Make sure the signal from the remote
control to the air conditioner is unobstructed.

REMOTE CONTROL BATTERY

REPLACEMENT

If the remote control stops working, the battery should
be replaced. The battery used is a 3-volt lithium
CR2025. This battery or an equivalent should be avail-
able at a local electronics store or electronics section of
a department store.
To replace the battery, find the small tab on the back
of the remote control. With a fingernail or screwdriver,
slide out the battery drawer using the tab. Remove
and recycle the old battery. Insert the new battery into
the drawer with the numbers facing up. The battery
will only fit into the drawer one way. Gently slide the
battery drawer back into the remote control.
