Safety information
Check the followings before installation and repair/
maintenance service.
Before brazing, remove dangerous and/or
flammable things around workplace that may
cause an explosion and fire.
Before brazing, remove the refrigerant within
the pipe or the product.
If you perform welding while refrigerant is in
the pipe, it may increase the pressure of the
refrigerant and cause the pipe to burst. If the
pipe bursts or explodes, it may cause severe
injury to the installer.
Use the nitrogen gas to eliminate oxide inside
the pipe during brazing.
Electric work must be done by qualified people,
complying the national wiring regulations and
installed according to the instruction stated in the
installation manual and must comply regulated
electrical specification.
Capacity shortage on the power circuit or
improper installation may cause electric shock or
fire.
Wiring must be connected with the designated
wires and it must be fixed securely so that it does
not apply any external force to the connection part
of the terminals.
If connection or fixation is not properly done, it
may cause heat generation or fire.
Neatly arrange the wires in the electrical parts to
make sure that electrical cover is closed securely
without any gaps.
If the cover is not properly closed, heat may
generate on the terminal and cause electric
shock or fire.
Exclusive circuit breaker (MCCB, ELB) must be
installed to the power supply.
Use ELCB that has harmonic wave prevent
function since the product uses inverter
compressor.
If the auxiliary circuit breaker is not installed,
power will not be cutoff in case of overcurrent
or current leakage and cause electric shock or
fire.
Do not use damaged parts. Otherwise, a fire or
electric shock may occur.

You must cut-off the power before you work
on, or adjust any power supply part for product
installation, maintenance, repair or any other
services.
This may result in electric shock.
Even when the power is off, it is very dangerous
to touch the inverter PCB and the fan PCB since
high pressure DC voltage is charged for those
parts.
When replacing/repairing the PCB, cut-off
the power and wait until the DC voltage is
discharged before replacing/repairing them.
(Wait for more than 15 minutes to allow those
parts to be fully discharged.)
You must ventilate the room if the refrigerant gas
leaks during the installation.
Toxic gas can be generated when the refrigerant
gas gets in contact with flammable substance.
Use chilled/heating water which is appropriate
according to water maintenance standard.
(Refer to page 64 for water maintenance standard.)
Deterioration of water may cause water leakage.
Contact the merchandise or service center for
measures against the situation where leaked
refrigerent is accumulated.
When refrigerant leaks and exceed dangerous
concentration level, it may cause suffocation
accidents. When installing the unit in a small
area, take measure to keep the refrigerant
concentration from exceeding allowable safety
limits in case of refrigerant leakage.
Follow regulations for disposing brine, cleaner, and
refrigerant.
It is against the law to dispose illegally, and also
harmful for humans and environment.
