13.1. GENERAL CHECK
12 DRAIN PIPING
12.1. 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 H(V)RNM(1)E/HVRNS1E
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
 NOTE:
Do not use this drain boss set in a cold area, because the drain
water may freeze.This drain boss is not sufcient 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.
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 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:

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 specied capacity.
 WARNING:
Check to ensure that screws for terminal block are tightly
tightened.
 CAUTION:
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 specied capacity.
 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.
