For units that have an auxiliary electric heater, DO NOT install the unit within 3 feet (1 meter) of
combustible materials.
DO NOT install the unit in a location that may be exposed to combustible gases. If combustible
gas accumulates around the unit, it may cause fire.
DO NOT operate your air conditioner in a wet room such as a bathroom or laundry room. Too
much exposure to water may cause electrical components to short circuit.
DO NOT put appendages or other objects into the air inlet or return grills.
DO NOT stop the appliance by directly cutting off the power. Turn off the unit first.
DO NOT install the appliance in areas with:
• oil, smoke, or volatile liquid; as plastic parts may deteriorate, adversely affecting the integrity
and functionality of the appliance.
• corrosive gas; as this may corrode copper piping and welds, adversely affecting the integrity
and functionality of the appliance.
DO NOT force-dry the filter using open flame or blowers, as this could damage it.
This appliance must be properly grounded during installation, or electrical shock may occur.
Install drainage piping according to the instructions in this manual. Improper drainage may
cause water damage to your home and property.
This appliance must be stored in a well ventilated area equal in size to the area specified for
operation.
Use proper measures to protect the unit from rodents and other small animals that may
damage electrical components, causing the unit to malfunction.
If wired control (i.e. a wall-mount thermostat) is to be used, it should be connected first before
powering up the unit, otherwise it may not funciton properly.
Only use a soft dry cloth or, as necessary, a slightly wet cloth with neutral detergent to clean
the casing of this appliance.
Before operating the unit under low temperature, connect it to power for 8 hours. If it is
deactivated for a short time, for example, one night, do not cut off the power (this is to protect
the compressor).
