DRAIN PIPING
9 DRAIN PIPING
9.1 DRAIN DISCHARGING BOSS
When the base of the outdoor unit is temporarily utilized as a
drain receiver and the drain water in it is discharged, this drain
boss is utilized to connect the drain piping.

Connecting procedure
1 Insert the rubber cap into the drain boss up to the extruded
portions.
2 Insert the boss into the unit base and turn approximately 40
degree counterclockwise.
3 Size of the drain boss is 32 mm (O.D.).
4 A drain pipe should be field-supplied.
?
N O T E
Do not use this drain boss set in a cold area, because the drain water
may freeze.This drain boss is not sufficient to collect all the drain water.
If collecting drain water is completely required, provide a drain-pan that is
bigger than the unit base and install it under the unit with drainage.
10 ELECTRICAL WIRING
10.1 GENERAL CHECK
1 Ensure that the field-supplied electrical components (mains
power switches, circuit breakers, wires, connectors and wire
terminals) have been properly selected according to the
electrical data indicated. Make sure that they comply with
national and regional electrical codes.
2 Following the Council Directive 2004/108/EC(89/336/EEC),
relating to electromagnetic compatibility, next table indicates:
Maximum permissible system impedance Z
interface point of the user's supply, in accordance with
EN61000-3-11.

4 Check to ensure that the power supply voltage is within
+/-10% of the rated voltage.
5 Check to ensure that power supply has an impedance low
enough to warranty not reduce the starting voltage more
than 85% of the rated voltage.
6 Check to ensure that the ground wire is connected.
7 Connect a fuse of specified capacity.

Check to ensure that screws for terminal block are tightly tightened.
Check to ensure that the indoor fan and the outdoor fan have stopped
before electrical wiring work or periodical check is performed.
Protect the wires, drain pipe, electrical parts, from rats or other small
animals. If not protected, rats may damage unprotected parts, and at
the worst, a fire will occur.
Wrap the accessory packing around the wires, and plug the wiring
connection hole with the seal material to protect the product from any
condensed water and insects.
Tightly secure the wires with the cord clamp inside the indoor unit.
Lead the wires through the knockout hole in the side cover when
using conduit.
Secure the cable of the remote control switch with the cord clamp
inside the electrical box.
Electrical wiring must comply with national and local codes. Contact
your local authority in regards to standards, rules, regulations, etc.
Check that the ground wire is securely connected.
Connect a fuse of specified capacity.
D A N G E R
Do not connect of adjust any wiring or connections unless the
main power switch is OFF.
Check that the earth wire is securely connected, tagged and
locked in accordance with national and local codes.
