6.5. Drainage Piping Work
1. Connect the flexible tube (supplied with the unit) to the drain port.
(Must not be bent more than 45 degrees.)
(Affix the tube using PVC adhesive then secure it with a band.)
2. Install a locally purchased drain pipe (PVC pipe, VP-25).
(Affix the pipe using PVC adhesive then secure it with a band.)
3. Insulate the tube and pipe. (PVC pipe, VP-25 and socket)
4. Check that drain flows smoothly.
5. Insulate the drain port with insulating material, then secure the mate-
rial with a band. (Both insulating material and band are supplied with
the unit.)

7. Electrical work
7.1. Precautions
s
Supply power from independently branched circuit.
s
Wiring should conform to applicable standards.
s
Route wires connecting indoor and outdoor units and power sup-
ply wires separately so that they do not contact each other out-
side of the unit.
s
The primary side of the control circuit transformer is wired for
use with 240 V power supply. Wiring must be modified for use
with a 220 or 230 V power supply. Refer to the circuit diagram for
details.
s
Never connect the power supply directly to the control wiring ter-
minals, as this will cause a unit failure.
s
Be sure to wire together the control wiring terminals, otherwise
the unit will fail.
s
The compressor will not operate unless the power supply phase
connection is correct.
