TIMER OPERATION
About the PROGRAM timer
The PROGRAM timer allows you to integrate OFF timer and ON timer operations in a single sequence. The se­quence can involve one transition from OFF timer to ON timer, or from ON timer to OFF timer, within a twenty­four hour period.
The first timer function to operate will be the one set near­est to the current time. The order of operation is indi­cated by the arrow in the remote control unit’s display (OFF ON, or OFF ON).
One example of PROGRAM timer use might be to have the air conditioner automatically stop (OFF timer) after you go to sleep, then start (ON timer) automatically in the morning before you rise.
About the ON timer
The timer function is designed to bring your room to a comfortable temperature by the set time; as a result, the unit automatically begins operation before the set time so that the room reaches the desired temperature by the time set on the timer.
The hotter it is in summer, or the colder it is in winter, the earlier that operation will begin.
* During Heating Operation ....... from 45 to 10 minutes be-
fore set time.
During Cooling/Dry Operation ... from 20 to 10 minutes be-
fore set time.
During Fan Operation .............. at the set time.
SLEEP TIMER OPERATION
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
Unlike other timer functions, the SLEEP timer is designed to set the duration of time in which the unit does not operate.

Dust can be cleaned from the air filter either with a vacuum
cleaner, or by washing the filter in a solution of mild de­tergent and warm water. If you wash the filter, be sure to allow it to dry thoroughly in a shady place before rein­stalling.
If dirt is allowed to accumulate on the air filter, air flow
will be reduced, lowering operating efficiency and increas­ing noise.
During periods of normal use, the air filters should be
cleaned every two weeks.
Hooks (two places)
When using the optional Air Cleaning Filter
Install the optional air cleaning filter set as instructed (installation instructions are furnished with the air cleaning filter set).
When used for extended periods, the unit may accumulate dirt inside, reducing its performance. We recommend that the
unit be inspected regularly, in addition to your own cleaning and care. For more information, consult authorized service personnel.
When cleaning the unit’s body, do not use water hotter than 100 °F, harsh abrasive cleansers, or volatile agents like benzene or thinner.
Do not expose the unit body to liquid insecticides or hairsprays.
When shutting down the unit for one month or more, first allow the fan mode to operate continuously for about one-half
day to allow internal parts to dry thoroughly.

TROUBLESHOOTING
Instructions relating to heating (*) are applicable only to “HEAT & COOL MODEL” (Reverse Cycle).
WARNING!
Before requesting service, perform the following checks:
In the event of a malfunction (burning smell, etc.), immediately stop operation, turn off the cir­cuit breaker, and consult authorized service personnel. Merely turning off the unit’s power switch will not completely disconnect the unit from the power source. Always be sure to turn off your circuit breaker to ensure that power is completely off.
NORMAL
FUNCTION
Symptom
Doesn’t operate immedi­ately:
Noise is heard:
Odor:
Mist or steam are emitted:
Problem
If the unit is stopped and then immediately started again, the com­pressor will not operate for about 3 minutes, in order to prevent fuse blowouts.
Whenever the power switch is turned off then on again, the pro­tection circuit will operate for about 3 minutes, preventing unit operation during that period.
During operation and immediately after stopping the unit, the sound of water flowing in the air conditioner’s piping may be heard. Also, noise may be particularly noticeable for about 2 to 3 minutes after starting operation (sound of coolant flowing).
During operation, a slight squeaking sound may be heard. This is the result of minute expansion and contraction of the front cover due to temperature changes.
*During Heating operation, a swoosh sound may be heard occa-
sionally. This sound is produced by the Automatic Defrosting op­eration.
Occasionally an odor may be emitted from the indoor unit. This may be the result of room odors (furniture, tobacco, etc.) which have been taken into the air conditioner.
During Cooling or Dry operation, a thin mist may be seen emitted from the indoor unit. This results from the sudden Cooling of room air by the air emitted from the air conditioner, resulting in condensation and misting.

Airflow is weak or stops:
Water is produced from the outdoor unit:
*During Heating operation, the outdoor unit’s fan may stop, and
steam may be seen rising from the unit. This is due to Automatic Defrosting operation.
*When Heating operation is started, fan speed is temporarily very
low, to allow internal parts to warm up.
*During Heating operation, if the room temperature rises above
the thermostat setting, the outdoor unit will stop, and the indoor unit will operate at very low fan speed. If you wish to warm the room further, set the thermostat for a higher setting.
*During Heating operation, the unit will temporarily stop opera-
tion (between 7 and 15 minutes) as the Automatic Defrosting mode operates. During Automatic Defrosting operation, the OPERATION indicator light will flash.
The fan may operate at very low speed during Dry operation or when the unit is monitoring the room’s temperature.
In the monitor AUTO operation, the fan will operate at very low speed.
*During Heating operation, water may be produced by the out-
door unit due to Automatic Defrosting operation.
