DO NOT
install the unit within 3 feet (1 meter) of combustible materials if the unit is equipped
with an auxiliary electric heater.
DO NOT
install the unit in a location that may 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 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. Ensure the unit is turned off 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 an open flame or blowers, as this could damage it.
This appliance must be properly grounded during installation, or electrical shock may occur.
Install the 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
operation.
Use proper measures to protect the unit from rodents and other small animals that may damage
electrical components, and cause the unit 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 in low temperature, connect it to power 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).
