Safety Precautions
ENGLISH
• Do not use the product for special purposes,
such as preserving foods, works of art, etc. It
is a consumer air conditioner, not a precision
refrigeration system.
- There is risk of damage or loss of property.
• When installting the unit in a hospital, commu-
nication station, or similar place, provide suffi-
cient protection against noise.
- The inverter equipment, private power gener-
ator, high-frequency medical equipment, or
radio communication equipment may cause
the air conditioner to operate erroneously, or
fail to operate. On the other hand, the air
conditioner may affect such equipment by
creating noise that disturbs medical treat-
ment or image broadcasting.
Operation
• Do not use the air conditioner in special envi-
ronments.
- Oil, steam, sulfuric smoke, etc. can signifi-
cantly reduce the performance of the air con-
ditioner or damage its parts.
• Do not block the inlet or outlet.
- It may cause failure of appliance or accident.
• Make the connections securely so that the out-
side force of the cable may not be applied to
the terminals.
- Inadequate connection and fastening may
generate heat and cause a fire.
• Be sure the installation area does not deterio-
rate with age.
- If the base collapses, the air conditioner
could fall with it, causing property damage,
product failure, or personal injury.
• Install and insulate the drain hose to ensure
that water is drained away properly based on
the installation manual.
- A bad connection may cause water leakage.
• Be very careful about product transportation.
- Only one person should not carry the prod-
uct if it weighs more than 20 kg.
- Some products use PP bands for packaging.
Do not use any PP bands for a means of
transportation. It is dangerous.
- Do not touch the heat exchanger fins. Doing
so may cut your fingers.
- When transporting the outside unit , sus-
pending it at the specified positions on the
unit base. Also support the outside unit at
four points so that it cannot slip sideways.
• Safely dispose of the packing materials.
- Packing materials, such as nails and other
metal or wooden parts, may cause stabs or
other injuries.
- Tear apart and throw away plastic packaging
bags so that children may not play with
them. If children play with a plastic bag
which was not torn apart, they face the risk
of suffocation.
• Turn on the power at least 6 hours before
starting operation.
- Starting operation immediately after turning
on the main power switch can result in
severe damage to internal parts. Keep the
power switch turned on during the opera-
tional season.
• Do not touch any of the refrigerant piping dur-
ing and after operation.
- It can cause a burn or frostbite.
• Do not operate the air conditioner with the
panels or guards removed.
- Rotating, hot, or high-voltage parts can
cause injuries.
• Do not directly turn off the main power switch
after stopping operation.
- Wait at least 5 minutes before turning off the
main power switch. Otherwise it may result in
water leakage or other problems.
• Auto-addressing should be done in condition
of connecting the power of all indoor and out-
doour units. Auto-addressing should also be
done in case of changing the indoor unit PCB.
• Use a firm stool or ladder when cleaning or
maintaining the air conditioner.
- Be careful and avoid personal injury.
