⑤Drain pipe

WARNING
• Do not insert the drain pipe directly in the drain ditch where toxic gases such as
sulffuric gas are produced.
Toxic gas may flow into the room.
CAUTION
• Install the drain pipe properly according to the installation manu And insulate it to
prevent from dew condensation.
Improper installation of drain pipe may cause damage of furniture drainage water
leaked or dew condensation.
Procedure
1. Connect the drain socket to the drain pipe (PV-20) provided at site and fix the joint with
adhesive tape, or the like.
2. When the pipe provided at site runs through a room, insulate the pipe with a commercial
insulator (Polyethylene foam: Specific gravity 0.03, thickness 15 mm or more) to prevent
dewing.
Decline the pipe lightly.
ATTENTION:
• Insulate the drain pipe to prevent dewing. (Especially in room and unit)
• Incline the drain pipe downward to the outlet (1/50 – 1/100). Upward bend or trap is
not allowed on the way.
• Use a commercial hard polyvinyl chloride pipe, PV-20, for the drain pipe.
<Use of adhesive agent is prohibited.>

⑥Wire extracting position and wire connecton

Control box position and power cable connection

●Electric work must be made by qualified electricians according to the "Engineering
standards concerning electric equipment", "Extension wiring regulations" and the
electric wiring work manual. Be sure to use dedicated electric circuits.
●Make sure to use specified wires for wiring, and connect them securely. Clamp the
wires to protect the terminal connection from external force.
●Make sure to protect the unit with the D-type grounding work.
●For details of wiring work, refer to the attached electric wiring work manual.
Control box
Open the air inlet grill by
holding the grips with
both hands and pulling to
this side.
Control box is located as
illustrated at left. Remove
the cover and make
connections.
Procedure
①Remove the control box cover (fixed with a screw).
②Introduce wires in the unit and connect securely on the terminals.
③Fix each wire with a clamp (for fixing).
④Install removed parts as they were.

⑦Check list after installation

●Check the following items after all installation work completed.
Check if;
The indoor and outdoor units are fixed securely?
Inspection for gas leakage is done?
Insulation work is properly done?
Water is drained properly?
Supply voltage is same as mentioned in the model name plate?
There is mis-wiring or mis-connection of piping?
Earth wiring is connected properly?
Cable size comply with specified size?
Any obstacle blocks airflow on air inlet and outlet?
