DO NOT install the unit within 3 ft (1 m) of combustible materials if the unit is equipped
with an auxiliary electric heater.
DO NOT install the unit in a location where it could be exposed to combustible gases. If
combustible gas accumulates around the unit, it could cause fire.
DO NOT operate your air conditioner in a room where it could be exposed to excessive
amounts of water, such as a bathroom or laundry room. Too much exposure to water
could cause the 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 could deteriorate, adversely affecting the
integrity and functionality of the appliance.
• corrosive gas; as this could corrode copper piping and welds, adversely affecting the
integrity and functionality of the appliance.
DO NOT force-dry the filter using an open flame or a blower, as these could damage it.
This appliance must be properly grounded during installation, or electrical shock could occur.
Install drainage piping according to the instructions in this manual. Improper drainage could
cause water damage to your home and property.
This appliance must be stored in a well ventilated area that is equal in size to the area specified
for the operation of the unit.
Use proper measures to protect the unit from rodents and other small animals that could
damage the electrical components of the unit, which could cause it to malfunction.
If wired control (i.e. a wall-mount thermostat) is to be used, it should be connected before
powering up the unit, otherwise it may not function properly.
Only use a soft dry cloth or a slightly wet cloth with neutral detergent to clean the casing of this
appliance.
If the unit has been disconnected from its power source for an extended period of time, before
operating the unit, connect it to its power source for 8 hours. If it is to be deactivated for a
short time, for example, one night, do not cut off the power (this is to protect the compressor).
