INSTALL THE DRAIN PIPE•
Use general hard polyvinyl chloride pipe (VP25) and connect it with adhesive (polyvinyl
chloride) so that there is no leakage. Do not perform air bleeding.
Main drain pipe (1)
Provide one trap on the
main drain pipe near the
indoor unit.

If the safety drain pipe is
connected to the main drain pipe,
make the connection below the

ELECTRICAL WIRING6.
WARNING
Electrical work must be performed in accordance with this Manual by a person
certied under the national or regional regulations. Be sure to use a dedicated circuit
for the unit.
An insufcient power supply circuit or improperly performed electrical work can cause
serious accidents such as electric shock or re.
Before starting work, check that power is not being supplied to the indoor unit and
outdoor unit.
Use the included connection cables and power cables or ones specied by the
manufacturer. Improper connections, insufcient insulation, or exceeding the allowable
current can cause electric shock or re.
For wiring, use the prescribed type of cables, connect them securely, making sure
that there are no external forces of the cables applied to the terminal connections.
Improperly connected or secured cables can cause serious accidents such as
overheating the terminals, electric shock, or re.
Do not modify the power cables, use extension cables, or use any branches in the
wiring. Improper connections, insufcient insulation, or exceeding the allowable
current can cause electric shock or re.
Match the terminal board numbers and connection cable colors with those of the
outdoor unit. Erroneous wiring may cause burning of the electric parts.
Securely connect the connection cables to the terminal board. In addition, secure the
cables with wiring holders. Improper connections, either in the wiring or at the ends of
the wiring, can cause a malfunction, electric shock, or re.
Always fasten the outside covering of the connection cable with the cable clamp. (If
the insulator is chafed, electric leakage may occur.)
Securely install the electrical box cover on the unit. An improperly installed electrical
box cover can cause serious accidents such as electric shock or re through exposure
to dust or water.
Install sleeves into any holes made in the walls for wiring. Otherwise, a short circuit
could result.
Install a ground leakage breaker. In addition, install the ground leakage breaker so
that the entire AC main power supply is cut off at the same time. Otherwise, electric
shock or re could result.
Install a ground leakage breaker.
If a ground leakage breaker is not installed, it may cause electric shock or re.
Always connect the earth (ground) cable.
Improper earthing (grounding) work can cause electric shocks.
Install the remote control cables so as not to be direct touched with your hand.
Perform wiring work in accordance with standards so that the air conditioner can be
operated safely and positively.
Connect the connection cable rmly to the terminal board. Imperfect installation may
cause a re.
Ground the unit.
Do not connect the earth (ground) cable to a gas pipe, water pipe, lightning rod, or a
telephone earth (ground) cable.
Improper earthing (grounding) may cause electric shock.
Do not connect power supply cables to the transmission or remote control terminals,
as this will damage the product.
Never bundle the power supply cable and transmission cable together. Bundling these
cables together will cause miss operation.
When handling PCB, static electricity charged in the body may cause malfunction of
the PCB. Follow the cautions below:
Establish a ground for the indoor and outdoor units and peripheral devices.•
Cut power (breaker) off.•
Touch metal part of the indoor and outdoor units for more than 10 seconds to •
discharge static electricity charged in the body.
Do not touch terminals of parts and patterns implemented on PCB.•

near the indoor unit and outdoor unit.
CAUTION
Be sure to execute the electrical work according to the Laws of each country and the
Installation Instructions. In addition, be sure to set as exclusive line and use the rated
voltage and circuit breaker.
