required.

Page 13
Normal Sounds
When your air conditioner is operating normally, you may hear sounds such as:
•Droplets of water hit the condenser, causing a
pinging or clicking sound. The water droplets
help to cool the condenser.
•Air movement from the fan.
•Clicks from the thermostat cycle.
•Vibrations or noise due to poor wall or window
construction.
•A high-pitched hum or pulsating noise caused
by the modern high-efficiency compressor
cycling on and off.
Drain Cup Installation and Operation
Your air conditioner uses a system where the water removed from the indoor air is channeled to the outdoor side
of the unit. The outdoor fan blade has a “slinger” ring attached to it that dips into the water and slings the water
onto the outdoor coil surface. This is the sound of water you hear during normal operation. The water quickly
evaporates on this warm surface and improves the efficiency of your air conditioner. In normal conditions the unit
can evaporate the water as fast as it is removed from the indoor air.
When it is in very humid weather, excess amounts of water may drop off the unit chassis. You could install the
condensate drain cup provided with the unit if this becomes a problem. See below Installation Instructions.
•Remove the unit chassis from the outer case. Refer to Page 6.
•Insert the condensate drain cup through the recessed 1/2” hole on the back center of the outer case.
•Place a 1/2” diameter hose or tube (not provided) on the drain cup bottom spout. The hose allows you to
route where you want the excess water to go.
•Reinsert the unit chassis into the outer case. The unit basepan overflow hole will be positioned directly
above the drain cup and will collect any water that might run out.

AIR CONDITIONER CARE
Your new air conditioner is designed to give you many years of dependable service. This section tells you how to
clean and care for your air conditioner properly. Call your local authorized dealer for an annual checkup. Remember,
the cost of this service call is your responsibility.
__________________________________________
Cleaning the Air Filter
The air filter is removable for easy cleaning. A clean
filter helps remove dust, lint, and other particles from
the air and is important for best cooling and operating
efficiency. Check the filter every 2 weeks to see
whether it needs cleaning.
NOTE: Do not operate the air conditioner without the
filter in place.
1. Turn off the air conditioner.
2. Grasp filter handle and slide filter out of unit.
3. Use a vacuum cleaner to clean air filter. If air filter
is very dirty, wash it in warm water with a mild
detergent. Do not wash air filter in the dishwasher or
use any chemical cleaners. Air dry filter completely
before replacing to ensure maximum efficiency.
Cleaning the Front Panel
1. Turn off the air conditioner
2. Remove the air filter and clean it separately. See
Cleaning the Air Filter.
3. Wipe the front panel with a soft damp cloth.
4. Air dry front panel completely.
__________________________________________
Repairing Paint Damage of Outside
Case
Check once or twice a year for paint damage. This is
very important, especially in areas near oceans or
where rust is a problem. If needed, Touchup with a
good grade enamel paint.
NOTE: To reduce paint damage during the winter,
install a heavy duty cover over the air conditioner
cabinet.
__________________________________________
Annual Maintenance
Your air conditioner needs annual maintenance to help
ensure steady, top performance throughout the year.
Call your local authorized dealer to schedule an
annual checkup. The expense of an annual inspection
is your responsibility.
4. Replace air filter by sliding filter into filter door.

Page 15

Air conditioner runs too long
The current air conditioner replaced an older
model. The use of more efficient components may
cause the air conditioner to run longer than an older
model, but the total energy consumption will be less.
Newer air conditioners do not emit the blast of cold air
you may be accustomed to from older units, but this is
not an indication of lesser cooling capacity or
efficiency. Refer to the efficiency rating (EER) and
capacity rating (in BTU/hr.) marked on the air
conditioner.
The air conditioner is in a heavily occupied room,
or heat-producing appliances are in use in the
room. Use exhaust vent fans while cooking or bathing
and try not to use heat producing appliances during
the hottest part of the day. A higher capacity air
conditioner may be required, depending on the size of
the room and external heating/cooling.

There is excessive heat or moisture (open
container cooking, showers, etc.) in the room. Use
a fan to exhaust heat or moisture from the room. Try
not to use heat-producing appliances during the
hottest part of the day.
The louvers are blocked. Install the air conditioner in
a location where the louvers are free from curtains,
blinds, furniture, etc.
The outside temperature is below 65ºF (18ºC). Do
not try to operate your air conditioner in the cooling
mode when the outside temperature is below 65ºF
(18ºC).
The temperature of the room you are trying to cool
is extremely hot. Allow extra time for the air
conditioner to cool off a very hot room.
Windows or doors to the outside are open. Close
all windows and doors.
The temperature set point or
Thermostat control is not at a cool enough setting.
Adjust the temperature set point to a cooler setting by
pressing the minus button to reduce the temperature
or adjust the Thermostat control to a cooler setting by
turning the knob clockwise. Turn the Fan control to
HIGH or Turbo Cool.
Temperature on display does not match
room temperature
When the compressor and fan motor turn off
during Power Saver mode, or after you turn off the
unit, a lower temperature reading than the actual
room temperature may be displayed for a short
period of time. This lower temperature reading is
caused by the temperature sensor being located close
to the cold evaporator coil. The actual room
temperature will display within a few minutes.
Water drips from cabinet into your house
The air conditioner is not properly leveled. The air
conditioner should slope slightly downward toward the
outside. Level the air conditioner to provide a
downward slope toward the outside to ensure proper
drainage. See the Installation instructions.
NOTE: Do not drill a hole into the bottom of the metal base and condensate pan.
