Operation
Do not use the air conditioner in special
environments.
• Oil, steam, sulfuric smoke, etc. can significantly reduce
the performance of the air conditioner 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 outside
force of the cable is not applied to the terminals.
• Inadequate connection and fastening may generate
heat and cause a fire.
Be sure the installation area does not deteriorate
with age.
• If the base collapses, the air conditioner could fall with
it, causing property damage, product failure, and per-
sonal injury.
Be very careful about product transportation.
• Only one person should not carry the product if it weighs more than 20 kg.
• Some products use PP bands dor 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 Outdoor Unit, suspending it at the specified posi-
tions on the unit base. Also support the Outdoor Unit at four points so that
it cannot slip sideways.
Install and insulate the drain hose to ensure that
water is drained away properly based on the instal-
lation manual.
• A bad connection may cause water leakage.
