INSTALLATION SITE INSTRUCTIONS
Indoor Unit
Select a site that allows for the following:
1. Ensure the installation complies with the installation minimum dimensions (defined below)
and meets the minimum and maximum connecting piping length and maximum change in
elevation as defined in the System Requirements section.
2. Air inlet and outlet will be clear of obstructions, ensuring proper airflow throughout the room.
3. Condensate can be easily and safely drained.
4. All connections can be easily made to outdoor unit.
5. Indoor unit is out of reach of children.
6. A mounting structure (i.e. wall, ceiling, floor,...) strong enough to withstand four times the full
weight and vibration of the unit.
7. Filter can be easily accessed for cleaning.
8. Leave enough free space to allow access for routine maintenance.
9. Install at least 10 ft. (3 m) away from the antenna of TV set or radio. Operation of the air
conditioner may interfere with radio or TV reception in areas where reception is weak.
An amplifier may be required for the affected device.
10. Do not install in a laundry room or by a swimming pool due to the corrosive environment.

TROUBLESHOOTING
PROBLEM
System does not restart.
Indoor unit emits unpleasant odor
when started.
You hear a"water flowing"sound.
A thin fog or vapor coming out
of the indoor unit when system is
running.
You hear a slight cracking sound
when the system stops or starts.
The system will not run.
The unit is not heating or cooling
adequately.
Water leakage from the
outdoor unit.

CAUSE/SOLUTION
Cause: The system has a built-in three-minute delay to prevent short and/or rapid
cycling of the compressor.
Solution: Wait three minutes for the protection delay to expire.
Cause: Typically unpleasant odors are the result of mold or mildew forming on
the coil surfaces or the air filter.
Solution: Wash indoor air filter in warm water with mild cleaner. If odors persist,
contact a qualified service professional to clean the coil surfaces.
Cause: It is normal for the system to make"water flowing"or"gurgling"sounds
from refrigerant pressures equalizing when the compressor starts and stops.
Solution: The noises should discontinue as the refrigerant system equalizes after
two or three minutes.
Cause: It is normal for the system to emit a slight fog or water vapor when
cooling extremely humid warm air.
Solution: The fog or water vapor will disappear as the system cools and
dehumidifies the room space.
Cause: It is normal for the system to make "slight cracking" sounds from parts
expanding and contracting during system starts and stops.
Solution: The noises will discontinue as temperature equalizes after 2 or 3 minutes.
Cause: There are a number of situations that will prevent the system from running.
Solution: Check for the following:
• Circuit breaker is "tripped" or "turned off."
• Power button of remote is not turned on.
• Batteries in the remote controller are low.
• Remote controller is in sleep mode or timer mode.
• Otherwise, contact a qualified service professional for assistance.
Cause: There are a number of reasons for inadequate cooling or heating.
Solution: Check the following:
• Remove obstructions blocking airflow into the room.
• Clean dirty or blocked air filter that is restricting airflow into the system.
• Seal around door or windows to prevent air infiltration into the room.
• Relocate or remove heat sources from the room.
Cause: It is normal for the outdoor unit to generate condensate
water in the reverse cycle heating and defrost mode.
Solution: This is normal. No action is required.
