Drain Piping - Toshiba MMU-UP0151SH-E Installation Manual

 Installation of ceiling panel
(Sold separately)
Install the ceiling panel according to Installation
Manual attached with it after piping / wiring work has
completed.
Check that installation of indoor unit and ceiling
opening part is correct, and then install it.
REQUIREMENT
• Joint the connecting sections of ceiling panel, ceiling
surface, ceiling panel and indoor unit closely.
Any gap between them will cause air leakage and the
generate condensation or water leakage.
• Remove the adjust corner caps at the four corners of
the ceiling panel, and then install the ceiling panel
onto the indoor unit.
Also, check that the claws are securely fit when
returning the adjust corner caps to its original position.
* Improper fitting of the claws may cause water leakage.
 Installation of wired remote
controller (Sold separately)
For installation of the wired remote controller, follow the
Installation Manual attached with the remote controller.
• Pull out the remote controller wire together with the
refrigerant pipe or drain pipe.
Pass the remote controller wire through upper side of
the refrigerant pipe and drain pipe.
• Do not leave the remote controller at a place
exposed to the direct sunlight and near a stove.
207-EN
 Installation of wireless
remote controller
(Sold separately)
The signal receiving unit of indoor unit can receive a
signal by distance within approx. 7 m. Based upon it,
determine a place where the remote controller is
operated and the installation place.
• Operate the remote controller, confirm that the
indoor unit receives a signal surely, and then install
it.
• Keep 1 m or more from the devices such as
television.
(Disturbance of image or noise may generate.)
• To prevent a malfunction and reception failure of the
remote controller, select a place where it is not
influenced by a fluorescent light, equipment
(Electronic whiteboard etc.) emitting infrared rays, or
direct sunlight.
• Switching the setting (A-B selection) of the wireless
remote controllers and the signal receiving unit
enables two indoor units installed in a room to be
respectively operated using two wireless remote
controllers.

Drain piping

CAUTION CAUTION
Following the Installation Manual, perform the drain
piping work so that water is properly drained, and
apply a heat insulation so as not to cause a dew
drop.
Inappropriate piping work may result in water
leakage in the room and wet of furniture.
 Piping / heat insulating
material
Require the following materials for piping and heat
insulating at site.
Hard vinyl chloride pipe VP25
Piping
(Outer dia.: 32 mm)
Foam polyethylene:
Heat insulator
Thickness 10 mm or more
 Flexible hose
Use the attached flexible hose to adjust center
discrepancy of the hard vinyl chloride pipe or to adjust
the angle.
• Do not use the flexible hose as stretched, or do not
deform it more extent than that in the following figure.
• Fix the soft end of the flexible hose with the attached
hose band.
• Use the flexible hose on a horizontal level.

REQUIREMENT
• Perform heat insulation of the drain pipes of the indoor
unit.
• Perform heat insulation of the connecting part with the
indoor unit.
An incomplete heat insulation causes dew drop.
• Set the drain pipe with downward slope (1/100 or
more), and do not make swelling or trap on the piping.
It may cause an abnormal sound.
• For length of the traversing drain pipe, restrict to 20 m
or less.
In case of a long pipe, provide support brackets with
interval of 1.5 - 2 m in order to prevent waving.

• Do not apply force to the connecting part of the drain
pipe.
• The hard vinyl-chloride pipe cannot be directly
connected to the drain pipe connecting port of the
Riser (Trap)
indoor unit.
For connection with the drain pipe connecting port, fix
the attached flexible hose with the hose band,
otherwise a damage or water leak is caused on the
90° Bend
drain pipe connecting port.
