Energy Saving Recommendations
The following recommendations will add greater efficiency to the
ductless system:
• Select a comfortable thermostat setting and leave it at chosen
setting. Avoid continually raising and lowering the setting.
• Keep the filter clean. Frequent cleaning may be necessary
depending on indoor air quality.
• Use drapes, curtains or shades to keep direct sunlight from heating
the room on very hot days.
• Limit the unit's run time by using the TIMER function.
• Do not obstruct the air intake on the front panel.
• Turn on the air conditioning unit before the indoor air becomes too
uncomfortable.
• DO NOT set the unit to excessive temperature levels.
• While cooling, close the curtains to avoid direct sunlight.
• Doors and windows should be kept closed to keep cool or warm air
in the room.
• DO NOT place objects near the air inlet and outlet of the unit.
• Clean the air filter every two weeks.

CARE AND MAINTENANCE
CLEANING YOUR INDOOR UNIT
CAUTION
ELECTRICAL SHOCK HAZARD
Failure to follow this caution may result in personal injury or
death. Always turn off power to the system before performing any
system cleaning or maintenance. Turn off the outdoor disconnect
switch located near outdoor unit. Be sure to disconnect the indoor
unit if on a separate switch.
CAUTION
BEFORE CLEANING OR MAINTAINING THE UNIT
Always turn the unit off and disconnect its power supply before
cleaning or maintaining the unit.
When removing filter, do not touch the metal parts in the unit. The
sharp metal edges can cut.
DO NOT use water to clean the inside of the indoor unit. This can
destroy insulation and cause an electrical shock.
DO NOT expose the filter to direct sunlight when drying. This can
shrink the filter.
CAUTION
Any maintenance and cleaning of outdoor unit should be
performed by an authorized dealer or a licensed service provider.
Any unit repairs should be performed by an authorized dealer or a
licensed service provider.
CAUTION
EQUIPMENT DAMAGE/OPERATION HAZARD
Failure to follow this caution may result in equipment damage or
improper unit operation. Operating the system with dirty air filters
may damage the indoor unit and could cause reduced cooling
performance, intermittent system operation, frost build-up on
indoor coil or blown fuses.
Contact an authorized service technician for repair or maintenance.
Improper repair and maintenance may cause water leakage, electrical
shock, or fire and may void your warranty.
DO NOT substitute a blown fuse with a higher or lower amperage
rating fuse, as this may cause circuit damage or an electrical fire.
Ensure the drain hose is set up according to the instructions. Failure to
do so could cause leakage and result in personal property damage, fire
and electric shock.
Ensure all wires are connected properly. Failure to connect wires
according to instructions can result in electrical shock or fire.
