Installing The Drain Pipe - Sanyo Classic PACi Serie Instrucciones De Instalación

(3) Thread the 3 hexagonal nuts and 2 washers (field supply)
onto each of the 4 suspension bolts (Fig. 3-5). Use 1 nut
and 1 washer for the upper side, and 2 nuts and 1 washer
for the lower side, so that the unit will not fall off the
suspension lugs.

(4) Adjust so that the distance between the unit and the ceiling
bottom is 12 to 17 mm (X Type) or 13 to 18 mm (XM
Type). Tighten the nuts on the upper side and lower side of
the suspension lug.
(5) Remove the protective polyethylene used to protect the fan
parts during transport.

3-4. Installing the Drain Pipe

<X Type>
(1) Prepare a standard hard PVC pipe (O.D. 32 mm) for the
drain and use the supplied drain hose and hose band to
prevent water leaks.
The PVC pipe must be purchased separately. The unit's
transparent drain port allows you to check drainage. (Fig.
3-6)

Align the hose

of the pipe.

CAUTION
Insert the drain pipe until it contacts the socket as shown
in Fig. 3-6, then secure it tightly with the hose band.
● Do not use adhesive when connecting the supplied
hose.
Reasons: 1. It may cause water to leak from the connection.
Since the connection is slippery just after the
adhesive has been applied, the pipe easily slips
off.
2. The pipe cannot be removed when maintenance
is needed.
● Do not bend the supplied drain hose 90° or more. The
hose may slip off.

● Align the hose bands with the end of the hose. Tighten
the hose band firmly. Make sure that the bead is not
covered by the hose band.
(Fig. 3-6)
(2) After checking the drainage, wrap the supplied packing
and drain pipe insulator around the pipe. (Fig. 3-7)
CAUTION
Tighten the hose clamps so their locking nuts face upward.

NOT E
Make sure the drain pipe has a downward gradient (1/100 or
more) and that there are no water traps.
CAUTION
Do not install an air bleeder as this may cause water to spray
from the drain pipe outlet. (Fig. 3-8)
CAUTION
● If it is necessary to increase the height of the drain pipe,
the section directly after the connection port can be
raised a maximum of 64 cm. Do not raise it any higher
than 64 cm, as this could result in water leaks. (Fig. 3-9)
● Do not install the pipe with an upward gradient from the
connection port. This will cause the drain water to flow
backward and leak when the unit is not operating. (Fig.
3-10)
Fig. 3-6
● Do not apply force to the piping on the unit side when
connecting the drain pipe. The pipe should not be
allowed to hang unsupported from its connection to the
unit. Fasten the pipe to a wall, frame, or other support as
close to the unit as possible. (Fig. 3-11)
● Provide insulation for any pipes that are run indoors.
