1 Ensure that the eld-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.

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 specied capacity.
N O T E
Check and test to ensure that if there is more than one source of
power supply, that all are turned OFF.
C A U T I O N
• 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 re 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 specied capacity.

14.1 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 Applicable Model
DBS-26 All units
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 eld-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 sufcient 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.
