Request an authorized service personnel to perform installation work.
Do not install this unit by yourself. Improper installation will cause injury,
electric shock, fire, etc.
In the event of a malfunction (burning smell, etc.), immediately stop
operation, turn off the electrical breaker, and consult authorized service
personnel.
WARNING
Do not install the unit in the following areas:
Do not install the unit near a source of heat, steam, or flammable gas.
•
Area filled with mineral oil or containing a large amount of splashed oil
•
or steam, such as a kitchen. It will deteriorate plastic parts, causing the
parts to fall or the unit to leak water.
Area that generates substances that adversely affect the equipment,
•
such as sulfuric gas, chlorine gas, acid, or alkali. It will cause the cop-
per pipes and brazed joints to corrode, which can cause refrigerant
leakage.
Area containing equipment that generates electromagnetic interference.
•
It will cause the control system to malfunction, preventing the unit from
operating normally.
Area that can cause combustible gas to leak, contains suspended
•
carbon fibers or flammable dust, or volatile inflammables such as paint
thinner or gasoline. If gas leaks and settles around the unit, it can cause
a fire.
Install the unit in a well-ventilated place avoiding rains and direct
•
sunlight.
Do not operate this unit when your hands are wet.
Touching the unit with wet hands will cause an electric shock.
If children may approach the unit, take preventive measures so that they
cannot reach the unit.
CAUTION
When detecting the room temperature using the remote controller, please
set up the remote controller according to the following conditions. If the
remote controller is not well set, the correct room temperature will not
be detected, and thus the abnormal conditions like “not cooled” or “not
heated” will occur even if the air-conditioner is running normally.
Locate where is not be affected by inflow of
•
outside air such as caused by opening and clos-
ing a door.
Locate where an average temperature for the
•
room being air-conditioned will be sensed.
Do not locate directly exposed to the outlet air
•
from the air conditioner.
Locate out of direct sunlight.
•
Locate away from the influence of other heat
•
sources.
Temperature sensor
Do not touch the remote controller PC board and PC board parts directly
with your hands.
Do not wire the remote controller cable and the bus wire together with or
parallel to the connection cables, transmission cables, and power supply
cables of the indoor and outdoor units. It may cause erroneous operation.
When installing the bus wire near a source of electromagnetic waves, use
shielded wire.
Do not set the DIP switches, either on the air conditioner or the remote
controller, in any way other than indicated in this manual or the manual
that is supplied with the air conditioner. Doing so may result in an im-
proper operation.
Do not touch the switches with sharp objects. Doing so will cause injury,
trouble, or electric shock.
Do not expose this unit directly to water. Doing so will cause trouble,
electric shock, or heating.
Do not set vessels containing a liquid on this unit. Doing so will cause
heating, fire, or electric shock.
Dispose of the packing materials safely. Tear and dispose of the plastic
