5. Installing the unit

5.1. Hanging the unit body

u Bring the indoor unit to an installation site as it is packed.
u To hang the indoor unit, use a lifting machine to lift and pass through
the hanging bolts.

6.3. Drain piping work

• Ensure that the drain piping is downward (pitch of more than 1/100) to the
outdoor (discharge) side. Do not provide any trap or irregularity on the way.
• Ensure that any cross-wise drain piping is less than 20 m (excluding the dif-
ference of elevation). If the drain piping is long, provide metal braces to pre-
vent it from waving. Never provide any air vent pipe. Otherwise drain may be
ejected.
• Use a hard vinyl chloride pipe VP-25 (with an external diameter of 32 mm)
for drain piping.
• Ensure that collected pipes are 10 cm lower than the unit body's drain port.
• Do not provide any odor trap at the drain discharge port.
• Put the end of the drain piping in a position where no odor is generated.
• Do not put the end of the drain piping in any drain where ionic gases are
generated.

Hanging structure
• Ceiling: The ceiling structure varies from building to one another. For detailed
information, consult your construction company.
• If necessary, reinforce the hanging bolts with anti-quake supporting members
as countermeasures against earthquakes.
* Use M10 for hanging bolts and anti-quake supporting members (field supply).

5.2. Confirming the unit's position and fix-
ing hanging bolts
u Ensure that the hanging bolt nuts are tightened to fix the hanging bolts.
u To ensure that drain is discharged, be sure to hang the unit at level us-
ing a level.
Caution:
Install the unit in horizontal position. If the side with drain port is installed
higher, water leakage may be caused.

1. Insert the drain hose (accessory) into the drain port (insertion margin: 32mm).
(The drain hose must not be bent more than 45° to prevent the hose from
breaking or clogging.)
(Attach the hose with glue, and fix it with the band (small, accessory).)
2. Attach the drain pipe (O.D. ø32 PVC TUBE PV-25, field supply).
(Attach the pipe with glue, and fix it with the band (small, accessory).)
3. Perform insulation work on the drain pipe (O.D. ø32 PVC TUBE PV-25) and
on the socket (including elbow).
4. Check the drainage. (Refer to [Fig. 6.4.1])
5. Attach the insulating material, and fix it with the band (large, accessory) to
insulate the drain port.
