5.2 DRAIN PIPE CONNECTION

1 The position of the drain pipe connection is shown below.
Common drain piping
2 Prepare a polyvinyl chloride pipe with a 32mm outer diameter.
3 Fasten the tubing to the drain hose with an adhesive and the
factory-supplied clamp. The drain piping must be performed
with a down-slope pitch of 1/25 to 1/100.
4 Do not apply excessive force to the drain pipe connection. It
could cause a damage.
5 Do not use a bent or twisted drain hose. It will cause water
leakage.

6.1 GENERAL
D A N G E R
• Turn off the main power switch to the indoor unit and the
outdoor unit before electrical wiring work or a periodical
check is performed.
• Check to ensure that the indoor fan and the outdoor fan
have stopped before electrical wiring work or a periodical
check is performed.
• Protect the wires, drain pipe, electrical parts, etc. from
rats or other small animals. If not protected, rats may
gnaw at unprotected parts and at the worst, a fire will oc-
cur.
C A U T I O N
• Use twisted shielded pair cable or shield pair cable for trans-
mission wires between the indoor and the outdoor units, and
connect the shielded part to the earth screw in the electrical
box of the indoor unit as shown below.
• Wrap the field supplied insulation around the wires, and plug
the wiring connection hole with the seal material to protect the
product from any condensate water or 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 using the cord
clamp inside the electrical box.
