DRAIN PIPING
11. DRAIN PIPING
11.1. 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.
Model
DBS-26
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
12. ELECTRICAL WIRING
12.1. 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 elec-
trical 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
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.

NOTE:
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.

6 Check to ensure that the capacity of power supply is enough.
If not, the compressor will be not able to operate because of
abnormal voltage drop at starting.
7 Check to ensure that the ground wire is connected.
8 Connect a fuse of specified capacity.
CAUTION:
Check to ensure that screws for terminal block are tightly tightened.
Check to ensure that the indoor water pump 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.
Avoid the wiring from touching the refrigerant pipes, water pipes,
plate edges and electrical parts inside the unit. If not do, the wires
will be damaged and at worst, a fire will occur.
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

Electrical wiring must comply with national and local codes.
Contact your local authority in regards to standards, rules,
regulations, etc.

DANGER:
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.
NOTE:
Check and test to ensure that if there is more than one source of
power supply, that all are turned OFF.
