Drain Piping - Toshiba Carrier MMU-UP0071HP-UL Manuel D'installation

 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.
• Make sure that the claws of the four adjust corner caps
are securely fit.
* Improper fitting of the claws may cause water
leakage.
 Installation of remote
controller (Soldseparately)
For installation of the wired remote controller, follow the
Installation Manual attached with the remote controller.
• Pull out the remote controller cord together with the
refrigerant pipe or drain pipe.
Be sure to pass the remote controller cord 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.
21-EN
 Wireless type
The sensor of indoor unit with wireless remote
controller can receive a signal by distance within
approx. 26'2" (8 m). Based upon it, determine a place
whe 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 3'3" (1 m) or more from the devices such as
television, stereo, etc.
(Disturbance of image or noise may generate.)
• To prevent a malfunction, select a place where is not
influenced by a fluorescent light or direct sunlight.
• Two or more (Up to 6 units) indoor units with wireless
type remote controller can be installed in the same
room.

Drain piping

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
dropping.
Inappropriate piping work may result in water
leakage in the room and wet of furniture.
 Pipe material, size and
insulation
Require the following materials for pipe and insulation
at site.
Hard vinyl chloride pipe VP25
Piping
(Outer diameter 1.3" (32 mm))
Foam polyethylene :
Insulation
Thickness 0.4" (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.
• Be sure to fix the soft end of the flexible hose with the
attached hose band.
• Use the flexible hose on a horizontal level.
REQUIREMENT
• Be sure to perform insulation of the drain pipes of
the indoor unit.
• Never forget to perform insulation of the
connecting part with the indoor unit.
An incomplete insulation causes dew dropping.
• 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.
4'11" to 6'7"
(1.5 to 2 m)

• For length of the traversing drain pipe, restrict to
65'7" (20 m) or less.
In case of a long pipe, provide support brackets with
interval of 4'11" to 6'7" (1.5 to 2 m) in order to prevent
waving.
Arched

Trap
• Set the collective piping as shown in the below figure.
As long as possible (3.9" (100 mm))
VP25 VP25 VP25
VP30 or more
Downward slope
1/100 or more
• Be sure not to 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
indoor unit.
For connection with the drain pipe connecting port, be
sure to use / fix the attached flexible hose with the
hose band, otherwise a damage or water leak is
caused on the drain pipe connecting port.
