• FINISH
Check that there is no gap between the unit and the drain hose insulation.
• When drain pump is used.
Do not cover the
panel window.
NOTE: Check for drainage
Pour about 1 liter of water from the position
shown in the diagram or from the airflow outlet to
the dew tray. Check for any abnormalities such
as strange noises and whether the drain pump
functions normally.
Make sure the drain water is properly drained.
6. ELECTRICAL WIRING
Electrical work must be performed in accordance with this Manual by a person certified
under the national or regional regulations. Be sure to use a dedicated circuit for the unit.
An insufficient power supply circuit or improperly performed electrical work can cause
serious accidents such as electric shock or fire.
Before starting work, check that power is not being supplied to the all units.
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 overheat-
ing the terminals, electric shock, or fire.
Securely install the electrical box cover on the unit.
An improperly installed electrical box cover can cause serious accidents such as electric
shock or fire through exposure to dust or water.
Install sleeves into any holes made in the walls for wiring. Otherwise, a short circuit
could result.
Use the included connection cables and power cables or ones specified by the
manufacturer. Improper connections, insufficient insulation, or exceeding the allowable
current can cause electric shock or fire.
Do not modify the power cables, use extension cables, or use any branches in the wir-
ing. Improper connections, insufficient insulation, or exceeding the allowable current can
cause electric shock or fire.
Match the terminal block numbers and connection cable colors with those of the outdoor
unit (or RB 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 fire.

CAUTION
WARNING
Always fasten the outside covering of the connection cable with the cable clamp. (If the
insulator is chafed, electric discharge may occur.)
Install an earth leakage breaker. In addition, install the earth leakage breaker so that the
entire AC main power supply is cut off at the same time. Otherwise, electric shock or fire
could result.
Always connect the earth (ground) cable.
Improper earthing (grounding) work can cause electric shocks.
Install the remote controller 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 firmly to the terminal board. Imperfect installation may
cause a fire.
If the supply cable is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualified persons in order to avoid a hazard.
Earth (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 controller terminals,
as this will damage the product.
Never bundle the power supply cable and transmission cable, remote controller cable
together.
Separate these cable by 50 mm or more.
Bundling these cables together will cause miss operation or breakdown.
When handling PCB, static electricity charged in the body may cause malfunction of the
PCB. Follow the cautions below:
• Establish an earth (ground) for the indoor and outdoor units and peripheral devices.
• Cut power (breaker) off.
• Touch metal part of the indoor unit for more than 10 seconds to discharge static elec-
tricity charged in the body.
• Do not touch terminals of parts and patterns implemented on PCB.
6.1. Electrical requirement
• Select the power cable type and size
in accordance with relevant local and
national regulations.
• Specifications for local wiring power cord
and branch wiring are in compliance with
local code
• Max. wire length: Set a length so that the voltage drop is less than 2%. Increase the wire
diameter when the wire length is long.
Breaker should be installed at every refrigerant system. Do not use a breaker in a different
refrigerant system.
Refer to the table for the breaker specifications of each installation condition. Perform
the power crossover wiring within the range of the same refrigerant system. When the
crossover wiring is done, make a connection for indoor units to satisfy conditions A and B
below.

small groups of 44 units or less and provide a breaker with capacity of 30 mA for each
group.

When the power crossover wiring is done,
make it so that the total of the MCA of the
connected RB units and indoor units does not
exceed the 15 A. For RB unit MCA, refer to the
RB unit installation manual.
If the capacity of connected RB units and
indoor units exceeds the upper limit, either
add breakers or use a breaker with a greater
capacity.
