• Easy place to connect drain hose to outside of room
• Easy place to connect copper tube with outdoor unit
•Secure enough distance from neighboring objects as
shown below.
•Secure enough distance from neighboring objects as
shown below.
• A place no reach of direct ray of sun (if necessary, shield the
light)
• No obstacles in front of air in/out grille
• A place having a drain out-let
• Easy place to connect copper tube with indoor unit
• Secure enough distance from neighboring objects as shown
below.
(Indoor unit) (Outdoor unit)
CAUTION : Do not hang the outdoor unit on the wall of building, in case of falling, it may cause a serious trouble and damage.
2 SPACE TO INSTALL
3 INSTALLATION OF INDOOR UNIT

REFRIGERANT TUBE CONNECTION
1) Cushion rubbers absorb vibration of
outdoor unit
2) The unit must be grounded for safety in
accordance with local electrical codes.
(Grounding resistance should be under
100 ohms
■ Specification and method of copper tube
• Connection method of copper tube is to make connection with flare nut at the end of the copper tube with a flare tool.

CAUTION
• Use designated diameter and thickness of tube.
• Connect all tube as short as possible and fix firmly.
• Less than 3M of the difference of height between indoor and outdoor unit is desirable.
• Fill up more refrigerant if the connection tube is longer than 5M (130g/M).
(The refrigerant volume filled from the factory is suitable for 5M connection)
• Be careful not to let in any dust or motes into the tube when the tube passes the wall.
• When insulating the connection, use foam rubber or equivalent.

ELECTRICAL WIRING
CAUTION
•Be sure to use designated wires and make it as short as possible
•Use an exclusive power supply for the air conditioner
•Use an electricity leakage interrupter having suitable capacity.
•Grounding resistance should be under 100 ohms and the grounding wire should be connected firmly to the
terminal of out door unit.
■ Wire connection of indoor and outdoor unit
•When connecting wires of indoor and outdoor unit, the numbers of terminal block and terminals of connecting wires should
match exactly as shown below.
•Terminals of connecting wires should be fixed firmly using wire fixing tool to the same direction of terminal board.
