Drain Piping Work - Carrier 40TGF UP Series Installation Manual

REQUIREMENT
Before installation of the indoor unit, be sure to remove
the cushion for transportation between the fan and the
bell mouth. Running the unit without removing the
cushion may damage the fan motor.
Be sure to remove the cushion for
transportation between the fan and the bell
mouth.
Installation of ceiling panel
(Sold separately)
Install the ceiling panel according to installation manual
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.

Wireless remote controller
The standard distance for signal reception is
approximately 8 m vertically against the signal
receiving unit. 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, stereo, fluorescent, 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 work

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.
Piping / Heat insulating material
Require the following materials for piping and heat
insulating at site.
Hard vinyl chloride pipe VP25
Piping
(Outer diameter : Ø32 mm)
Foam polyethylene:
Heat insulator
Thickness 10 mm or more
Flexible hose
Use the attached flexible hose to adjust centre
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 heat insulation of the drain pipes of
the indoor unit.
Never forget to perform heat insulation of the
connecting part with the indoor unit.
An incomplete heat 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.

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 to 2 min order to prevent waving.

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.
