Connecting Duct To Indoor Unit - Panasonic Inverter R32 Series Technical Data & Service Manual

1
Installing the Drain Pipe
(1) Prepare standard hard PVC pipe (O.D. 32 mm) for the drain
and use the supplied hose band to prevent water leaks.
The PVC pipe must be purchased separately.
The transparent drain part on the unit allows you to check
drainage.
CAUTION
Do not use adhesive tape at the drain connection port on
the indoor unit.
Insert the drain pipe until it contacts the socket, and then
secure it tightly with the hose band.
Do not bend the supplied drain hose, please keep it
straight.
Tighten the hose clamps so their locking nuts face
upward. (Fig. 1-11-27)
Hose band (Supplied)
Drain insulator (Field supply)
(The thickness must be at
least 8 mm.)
Please do not glue.
Make sure that there is no clearance here.
(2) After connecting the drain pipe securely, wrap the supplied
packing and drain pipe insulator around the pipe, then secure
it with the vinyl clamps . (Fig. 1-11-28)
Drain insulator (Field supply)
NOTE
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. 1-11-29)
Prohibited
•
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 500 mm. Do not raise it any higher
than 500 mm, as this could result in water leaks.

Do not install the pipe with an upward gradient from the
connection port. This will cause the drain water to fl ow
backward and leak when the unit is not operating.
(Fig. 1-11-31)
Prohibited
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. 1-11-32)
Make sure all connecting PVC pipes are supported to the roof
structure, and the drain line is installed straight.

Connecting Duct to Indoor Unit

(1) Install the duct (Field supply) for the Dimension of the
installation hole.
Use M5 self-tapp Screws for installation see the Figure 1-11-21.
(2) The duct connection of the air outlet needs thermal insulation.
Air outlet
NOTE
•
Select an air-intake grille with a filter at a local shop.
•
To get clean air and to extend the service life of the
air conditioner, an air filter must be installed in the air
intake. For installation and cleaning the air filter, consult
your dealer or service center.
