Safety Precautions
Service Manual 7
After completing service work, make sure
that refrigerant gas is not leaking.
- If the refrigerant gas leaks and is exposed to a
fan heater, stove, oven, or other heat source, it
may generate noxious gases.
Do not reconstruct or change the settings of
the protection devices.
- If the pressure switch, thermal switch, or other
protection device is shorted and operated
forcibly, or parts other than those specified by
LG Electronics are used, fire or explosion may
result.
Do not install the unit where combustible gas
may leak.
- If the gas leaks and accumulates around the
unit, an explosion may result.
Do not use the air conditioner where food,
pets, plants, precision instruments, or art-
work are kept.
- The quality of the food, etc. may deteriorate.
Do not use the air conditioner in special envi-
ronments.
- Oil, steam, sulfuric smoke, etc. can significantly
reduce the performance of the air conditioner or
damage its parts.
Do not install the unit on a structure that may
cause leakage.
- When the room humidity exceeds 80% or when
the drain pipe is clogged, condensation may drip
from the indoor unit. Perform collective drainage
work together with the outdoor unit, as required.
Take measures to prevent children from
touching the unit.
- Injuries such as cuts could occur if a child
touches the surface of the fins on the heat
exchanger.
Cautions for electrical work and movement
Ground the unit.
- Do not connect the ground wire to gas or water
pipes, lightning rods, or telephone ground lines.
Improper grounding may result in electric shock.
Install the power cable so that tension is not
applied to the cable.
- Tension may cause the cable to break and gen-
erate heat and cause a fire.
Use power cables of sufficient current carry-
ing capacity and rating.
- Cables that are too small may leak, generate
heat, and cause a fire.
Use only a circuit breaker and fuse of the
specified capacity.
- A fuse or circuit breaker of a larger capacity or a
steel or copper wire may result in a general unit
failure or fire.
