WARNING

1) Install strictly in accordance with these instructions.
If installation is not done properly, water leakage, an
electric shock and a fi re may occur.

2) Only use the supplied accessories and authorised parts
for installation. Failure to do so may cause the unit to fail
and cause water leakage, electrical shock or fi re.

3) Install in a suitable location which can comfortably hold
the unit’s weight. If not installed properly, the set will fall
and cause damage or injury.

4) For all electrical work, follow the requisite national
wiring regulations and these installation instructions. An
independent circuit and single outlet must be used. If
electrical circuit capacity is insuffi cient or electrical work
is defective, it may cause an electric shock or fi re.

5) Use the specifi ed cable, connect tightly and clamp the
cable so that the terminal is not impacted by any force.
If the connection or fi xing is not adequate, it will cause
overheating or a fi re at the connection point.

6) Wiring routing must be properly arranged so that control
board cover is fi xed securely. If control board cover is not
fi xed perfectly, it will cause overheating at connection
point of terminal and result in fi re or electric shock.

7) When doing piping connections, take care not to let
gases other than the specifi ed refrigerant go into
the refrigeration cycle. Otherwise, it will cause lower
capacity, abnormally high pressure in the refrigeration
cycle and result in an explosion and personal injury.

8) Do not modify the length of the power supply cord or use
an extension cord. Do not share the single outlet with
other electrical appliances. Doing so will cause fi re or
electric shock.

CAUTION

1) This equipment must be earthed and installed with an
earth leakage current breaker. It may cause an electric
shock if grounding is not done correctly.

2) Do not install the unit in a place where leakage of a
fl ammable gas may occur. If gas leaks and accumulates
near the unit, it may cause a fi re.

3) Carry out drainage piping as specifi ed in these
installation instructions. If drainage is not done correctly,
water may enter the room and damage the furniture.
