4. Fixing hanging bolts
4.1. Fixing hanging bolts
[Fig. 4.1.1] (P.2)
(Give site of suspension strong structure.)
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. Installing the unit
5.1. Hanging the unit body
`
Bring the indoor unit to an installation site as it is packed.
`
To hang the indoor unit, use a lifting machine to lift and pass through the
hanging bolts.
[Fig. 5.1.1] (P.2)
[Fig. 5.1.2] (P.2)
5.2. Confirming the unit’s position and fixing
hanging bolts
`
Use the gage supplied with the panel to confirm that the unit body and
hanging bolts are positioned in place. If they are not positioned in place, it
may result in dew drops due to wind leak. Be sure to check the positional
relationship.
`
Use a level to check that the surface indicated by
A
is at level. Ensure that
the hanging bolt nuts are tightened to fix the hanging bolts.
`
To ensure that drain is discharged, be sure to hang the unit at level using a
level.
[Fig. 5.2.1] (P.2)
Caution:
Install the unit in horizontal position. If the side with drain port is installed
higher, water leakage may be caused.
6. Connecting drain pipe
To avoid dew drops, provide sufficient antisweating and insulating work to the drain
pipes.
6.1. Drain pipe specifications
6.2. Drain pipe
[Fig. 6.2.1] (P.2)
6.3. Drain piping work
•
Ensure that the drain piping is downward (pitch of more than 1/100) to the out-
door (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 differ-
ence of elevation). If the drain piping is long, provide metal braces to prevent 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 gener-
ated.
[Fig. 6.3.1] (P.3)
Grouped piping
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 break-
ing 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 insu-
late the drain port.
