1. Safety Precautions
Before installing the unit, make sure you read all the
“Safety Precautions”.
The “Safety Precautions” provide very important
points regarding safety. Make sure you follow them.
Please report to or take consent by the supply
authority before connection to the system.
• Do not touch the upper air outlet vane or the lower air outlet
damper during operation. Otherwise, condensation may form and
the unit may stop operating.
Disposing of the unit
When you need to dispose of the unit, consult your dealer.
Caution:
• Do not use any sharp object to push the buttons, as this may
damage the remote controller.
• Never block or cover the indoor or outdoor unit’s air inlets or outlets.
• Never wipe the remote controller with benzene, thinner chemical
rags, etc.
• Do not operate the unit for a long time in high humidity, e.g.
leaving a door or window open. In the cool mode, if the unit is
operated in a room with high humidity (80% RH or more) for a
long time, water condensed in the air conditioner may drop and
wet or damage furniture, etc.
• Young children must be supervised to ensure that they do not
play with the air conditioner.
• If the refrigeration gas blows out or leaks, stop the operation of
the air conditioner, thoroughly ventilate the room, and contact
your dealer.
• This appliance is intended to be used by expert or trained users
in shops, in light industry and on farms, or for commercial use by
lay persons.
• This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental capabilities,
or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance
by a person responsible for their safety.
• When installing or relocating, or servicing the air conditioner, use
only the specified refrigerant (R410A) to charge the refrigerant
lines. Do not mix it with any other refrigerant and do not allow air
to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of
abnormal high pressure in the refrigerant line, and may result in
an explosion and other hazards. The use of any refrigerant other
than that specified for the system will cause mechanical failure
or system malfunction or unit breakdown. In the worst case, this
could lead to a serious impediment to securing product safety.
Warning:
• These appliances are not accessible to the general public.
• The unit must not be installed by the user. Ask the dealer or an
authorized company to install the unit. If the unit is installed
improperly, water leakage, electric shock or fire may result.
• Do not stand on, or place any items on the unit.
• Do not splash water over the unit and do not touch the unit with
wet hands. An electric shock may result.
• Do not spray combustible gas close to the unit. Fire may result.
• Do not place a gas heater or any other open-flame appliance
where it will be exposed to the air discharged from the unit.
Incomplete combustion may result.
• Do not remove the front panel or the fan guard from the outdoor
unit when it is running.
• Never repair the unit or transfer it to another site by yourself.
• When you notice exceptionally abnormal noise or vibration, stop
operation, turn off the power switch, and contact your dealer.
• Never insert fingers, sticks etc. into the air inlets or outlets.
• If you detect odd smells, stop using the unit, turn off the power
switch and consult your dealer. Otherwise, a breakdown, electric
shock or fire may result.

persons without supervision.
