Removal and inspection
Check and repair
The performance of the air condi-
■
tioner decreases due to long-term
service and internal dirt.
Odor may result from using condition,
■
or poor drainage of condensed water
may result from dust deposit.
The check and repair are different
■
from common ones. You'd better
ask for special technical service.
Please contact the specialty shop
or technical service center for help.
Safety precautions for Installation
1. For the sake of safety, please pay attention to the following safety precautions
Warning
Users are not allowed to install the machine by
themselves.
Improper installation may cause fire, electric shock, water
·
leakage or injury from machine falling.
Please contact the specialty shop or technical service center
for help.
The machine should be installed in a place which
can support its weight.
If the machine is installed in a place which is not solid
·
enough, there will be a risk of injury from machine falling.
Cables between indoor and outdoor unit shall be
connected properly as specified, and connecting
terminals for the cables be fixed firmly without being
affected by external force.
Poor connection or fixture may cause fire.
·
Installation shall be implemented properly based on
installation instructions
Improper installation may cause fire, electric shock, water
·
leakage or injury from machine falling.
Please ventilate room in the event of refrigerant
leakage during installation.
Exposure of refrigerant to open flame can produce toxic gas.
·
When installing or servicing the unit,use appropriate
protective equipment and tools for safety.
Failure to do so could cause injury.
·
Operation noise should be
also considered.
Don't place articles at the outlets of
■
outdoor unit. For the placement will
reduce the efficiency and increase
noise in operation.
If there is abnormity in operation,
■
please contact the specialty shop
or technical service center for help.
In the event of installation or removing, any
substance other than refrigerant shouldn't be mixed
into the refrigerant circuit.
If air is mixed in the circuit, system pressure will increase to
·
cause breakage.
Don't fill other refrigerant than specified while
installing or moving the unit.
If so, it may become the cause of problems such as malfunc-
·
tion, false action and mechanical fault and possibly leads to
major safety accidents in some cases.
When pumping down the refrigerant, stop the
compressor before disconnecting the refrigerant
pipes.
If the refrigerant pipes are disconnected while the compressor
·
is running and the stop valve is open, air could be drawn in and
the pressure in the refrigeration cycle could become abnor-
mally high. This could cause the pipes to burst or injury.
When installing the unit, securely connect the
refrigerant pipes before starting the compressor.
If the compressor is started before the refrigerant pipes are
·
connected and when the stop valve is open, air could be
drawn in and the pressure in the refrigeration cycle could
become abnormally high. This could cause the pipes to
burst or injury.
Electrical work should be performed according to
installation instructions. Be sure to use special
power supply of circuit.
Fire or electric shock may result from insufficient capacity or
·
incomplete construction for the power supply circuit.

When you want to remove
the machine
When removing and reinstalling
■
the air conditioner due to room
enlargement or relocation, please
ask for special technical service.
Warining
Don't reapair or remove the air
conditioner by yourself.
Maloperation may cause fire, electric
shock, injury by unit drop and water
leakage. If the air is mixed in the
refrigerant, pressure may increase to
lead to breakage. Thus, please contact
the specialty shop or technical service
center for help.
