Operation
● Do not insert ngers or objects into air inlet/outlet. Injury can result from rotating fan blades or energized
electrical components.
● Do not touch the wired or wireless controller with wet hands. It can result in failure of the wired or
wireless controller or an electrical shock.
● Hair spray, insecticides, lacquers, and other pressurized substances should not be used within 3.3ft (1m)
of any air conditioning unit. It can react with energized electrical components and cause re.
● Do not install the indoor unit anywhere discharge airow can pass directly toward nearby heating
equipment (space heaters). It may interfere with the combustion process in these units.
● Air circulation should be optimized to achieve the best distribution pattern and not settle into isolated
pockets that can make people uncomfortable.
● When the indoor unit is operating with heating equipment, ventilate a room sufciently. Any leaked
refrigerant gases that happen to come into contact with any heat source can become toxic on contact and
can cause suffocation in the immediate area.
● Shut down at the main power source if the Ground Fault Circuit Interrupter (GFCI) activates frequently.
Contact your distributor or contractor immediately. Failure to act accordingly can result in serious injury
and damage to the unit.
● If you smell anything burning, shut down the unit and turn OFF the power at the main power source.
Contact the re department and your installer or electrical contractor.
● Make sure that a test for leakage of refrigerant gases is performed. The refrigerant used for this unit (HFC
R410A), is a non-ammable, non-toxic, and odorless gas. However if refrigerant should leak and make
contact with sparks and re; then toxic gas is generated. Also, because the uorocarbon is heavier than
air, the oor surface will be lled with it, which can cause suffocation.
If uorocarbon gas should leak, turn OFF all heating equipment and ventilate the room immediately. Mop
down or vacuum oor areas of residual toxic particulate.
● Do not operate indoor units with the electrical box and switch panel open and exposed. Incidental contact
with energized components can prove fatal.
● When a wireless controller is used, put a distance of at least 3.3ft (1m) between the indoor unit and
electric lighting. If not, the receiver part of the unit may be difcult to receive operation commands due to
effect of the electric lighting.
