The drain hose can be connected at either side of the indoor unit.
The unit has been shipped with the drain hose connected at left (viewed from the back of
the unit) and the drain cap applied at right.
(1) Remove the both side panels.
(2) Remove the screw and remove the drain holder from drain pan.
(3) Pull out the drain cap.
(4) Connect the drain hose to the right, attach the screw and insert the drain cap to the
left.

Installation method of Drain cap
Use a hexagonal wrench (4 mm at opposite
side) to insert the drain cap, till the drain cap
contacts the tip of drain cook.
Insert the drain hose and drain cap into the drain port, making sure that it comes in con-
tact with the back of the drain port, and then mount it. If the drain hose is not connected
properly, leaking will occur.

5. 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.
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.
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. Improp-
erly connected or secured cables can cause serious accidents such as overheating the
terminals, 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 board numbers and connection cable colors with those of the out-
door 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.
Always fasten the outside covering of the connection cable with the cable clamp. (If the
insulator is chafed, electric discharge 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 fire through exposure to
dust or water.
Install sleeves into any holes made in the walls for wiring. Otherwise, a short circuit
could result.
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 cable 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 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.
5.1. Electrical requirement
Voltage rating
Operating range
• 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.
