Drain Pump Kit installation Manual
Please read this Installation Manual carefully before installing the Air Conditioner.
• This Manual describes the installation method of the DRAIN PUMP KIT.
• For installation of the outdoor unit, follow the Installation Manual attached to the outdoor unit.
Z_ WARNING
For this Drain Pump Kit, please use the Elbow Piping Kit (MODEL: TCB-KP12CUL, TCB-KP22CUL) sold separately.
If using a piping kit procured locally, it may cause a water leak or so on.
This Air Conditioner isa new type which adopts a new refrigerant HFC (R410A) instead of the conventional
refrigerant R22 in order to prevent destruction of the ozone layer.

1ECAUTION FOR SAFETY
•Ensure that all Local, National and International regulations are satisfied.
• Read this "PRECAUTIONS FOR SAFETY" carefully before Installation.
• The precautions described below include the important items regarding safety. Observe them without fail.
• After the installation work, perform a trial operation to check for any problem.
Follow the Owner's Manual to explain how to use and maintain the unit to the customer.
• Turn off the main power supply switch (or breaker) before the unit maintenance.
• Ask the customer to keep the Installation Manual together with the Owner's Manual.
\ WARNINGS
,Ask an authorized dealer or qualified installation professional to install/maintain the air
conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
,Turn off the main power supply switch or breaker before attempting any electrical work.
Make sure all power switches are off. Failure to do so may cause electric shock.
, Connect the connecting cable correctly.
If the connecting cable is connected in a wrong way, electric parts may be damaged.
, When moving the air conditioner for the installation into another place, be very careful not to
enter any gaseous matter other than the specified refrigerant into the refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration cycle becomes abnormally
high and it resultingly causes pipe burst and injuries on persons.
,Do not modify this unit by removing any of the safety guards or by by=passing any of the safety
interlock switches.
, Exposure of unit to water or other moisture before installation may cause a short=circuit of
electrical parts.
Do not store it in a wet basement or expose to rain or water.
, After unpacking the unit, examine it carefully if there are possible damage.
,To avoid personal injury (with sharp edges), be careful when handling parts.
,Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
, Electrical work must be performed by a qualified electrician in accordance with the Installation
Manual.
An insufficient power supply capacity or inappropriate installation may cause fire.

Tightening torque of flare pipe connections
Pressure of R410A is higher than that of R22.
(Approx. 1.6 times) Therefore, using a torque
wrench, tighten the flare pipe connecting sections
which connect the indoor and outdoor units of the
specified tightening torque.
Incorrect connections may cause not only a gas
leak, but also a trouble of the refrigeration cycle.

[] Thermal insulating process
Apply thermal insulation to pipes at liquid and gas
sides separately.
• Be sure to use thermal insulator with heat
resisting temperature 248°F (120°C) or more for
pipes at gas side.
• Using thermal insulators attached to the indoor
unit and Elbow Piping Kit, apply thermal
insulating process surely to pipe connecting
section without clearance.
When fixing insulator to the elbow type pipe
temporarily with the banding band attached to
the Elbow Piping Kit, wrap the insulator using
vinyl tape so that there is no clearance.
CAUTION
Apply thermal insulating process surely so that no
exposure cannot be found up to the end of the
pipe connecting section of the indoor unit.
(if a part of the pipe is exposed, leakage may be
caused.)

[] Connection of drain hose at
indoor unit side
1. Insert the drain hose attached to the indoor unit
intothe drain pipe connecting port of the indoor
unit's and into the drain pipe connecting port of
the Drain Pump Kit's drain pan.
In this time, insert the drain hose until it strikes
on the connecting port of the drain pipe.
2. Align the hose band attached to the indoor unit
with the end of pipe connecting port, and then
tighten itfirmly.
3. Cut off to 6.3" x 7.9" (160mm x 200mm) the
thermal insulator 7.9" x 7.9" (200mm x 200mm)
for drain hose attached to the indoor unit.
Using it, lap the connecting section of drain
pan and drain hose without clearance, and
then tighten it with two banding bands attached
to the indoor unit so that thermal insulator does
not open.

4DRAIN 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.
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.' O1.3" (O32mm))
Foam polyethylene '
Heat insulator Thickness 0,4" (10mm) or more
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 dewing.
• 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 65' 7" (20m) or less.
In case of a long pipe, provide support brackets
with interval of 4' 11" to 6' 7" (1.5m - 2m) in As/longaspossible3.9" (100ram)
order to prevent waving. __5.y__ VP25

• Set the collective piping as shown in the right figure.
• 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.
Adhesive inhibited :
Use the attached flexible hose and hose band for connecting the drain hose to the drain piping connecting part.
If applying the adhesive, socket will be damaged and cause water leakage.
