Please read this manual and the air conditioner manual carefully before use.
Safety Precautions
Please read these”Safety Precautions”carefully before performing installation
work.
The precautions shown here are divided into” Warning”and” Caution”,but those
that are likely to lead to serious consequences such as death or serious
injury if installation is performed incorrectly are noted collectively in the
” Warning”area. However,even the items described in the” Caution”area may lead
to serious consequences depending on the situation.Observe all of the
following,as each contains important information regarding safety.
After the installation work is complete,perform a test run and check that
there are no abnormalities. In addition,please ask the customer to keep this
manual.

The drain up kit can be installed on the left or right of the air conditioner. The figure below shows the case of installation on the left.
Warning
For drainage of air conditioners. Do not use for any other application.If the
usage application is incorrect,fire/water leakage,etc.may result.
Regarding installation,ask your dealer or a specialist. If you perform
installation yourself and there are imperfections in the installation,water
leakage/ electrocution/fire may result.
For installation parts,be sure to use accessories and parts with the
designated specifications. If parts with the designated specifications are not
used,water leakage/electrocution/fire may result.
Be sure to turn off the power supply before performing installation work.If
electrical parts are touched while the power supply is turned on,electrocution
may result.
Make sure to perform installation work properly

Caution
For drainage work,install the pipes according to this installation manual to
ensure proper drainage,and insulate it to prevent condensation. If there are
imperfections in the pipe work,water may leak and cause household goods to get
wet.
Do not install in locations such as the following. Locations where flammable
gas may leak,locations where carbon fibre and flammable dust float,or
locations where volatile flammable materials such as thinner and gasoline are
handled. If gas leaks and collects around the drain up kit,ignition of fire
may result. Locations where there are machines that generates electromagnetic
waves. It may cause abnormalities to occur in the control system,making normal
operation impossible.

Preparation of the indoor unit
For things such as the construction procedure of the indoor unit,refer to the installation manual attached to the indoor unit.
Caution
Be sure to work with the power supply turned off
When connecting terminals to the inter-unit wiring terminal block,
attach them correctly as shown in the figure below. If the crimp terminals are
both installed in the same orientation accidentally,the terminal contact area
will decrease and there will be a risk of overheating and burning.

Precautions for power supply wire/earth wire
Use round type crimp terminals for connecting the inter-unit wiring terminal block and
the earth wire. If you for some reason cannot use round type crimp terminals,
be sure to observe the following items.
Do not connect 2 wires with different diameters to the inter-unit wiring terminal block.
(There is a risk of abnormal heat generation due to loose wires, etc.)
Connect the wire securely using the specified power wire, and secure it so that
external force is not applied to the terminal part. Use an appropriate screwdriver to tighten the terminal

screws. A screwdriver with a head that is too small will
damage the screw heads and make proper tightening impossible.
If the terminal screws are tightened too much, the screws may be damaged.

kit,and perform the following steps.
1.Take out the drain hose attached to the indoor unit. If installing the drain
up kit on the left,move the indoor unit drain cap to the right side and re-
attach it. For how to move and re-attach,check the indoor unit installation
manual.

(6)When installing the drain up kit right next to the indoor unit, cut the
drain hose with a something such as a cutter to dimension A and dimension B
below(in that order).
Dimension B may not be as specified depending on the size of the indoor unit
pipe outlet,so use dimension B as a guide only.
If you want to install the drain up kit at a distance from the indoor
unit,adjust the distance using hard PVC pipe(VP13)and the soft socket.

When connecting the relay harness, remove either the CN15 or X15A short
circuit connector. NOTE 1) Be sure to turn on the drain up kit power supply.
If the power supply is not turned
on, the air conditioner will stop abnormally and operation will not be
possible. NOTE 2) The relay harness cannot be extended. (It may malfunction
due to noise) NOTE 3) When the power supply is turned on, the K2R contact
closes and becomes a
non-voltage constant B contact.

to the mounting plate.
(2)Tighten the hose clamp around the drain hose. (3)Wrap the thermal
insulation around the hose clamp to insulate it.

Caution
Local pipe such as PVC pipe cannot be directly connected to the drain
socket.Be sure to use the attached drain hose.
Tighten the hose clamp with a torque of 1.0 to 1.2 Nm.
(4)Connect the outlet pipe. Connect the soft drain pipe to the soft drain pipe
connection port. Tighten the connection between the drain up kit and the soft
socket
with a hose clamp and wrap it with thermal insulation. Be sure to use adhesive
to connect the soft drain pipe and the
local drain pipe in the ceiling.
Caution
Outlet pipe parts are locally procured. Be sure to thermally insulate the
drain pipe. Be sure to make a downward slope (1/100 or more) for the
horizontal
section of the drain pipe so that there will be no trapped air. If the
horizontal section is long, install a support bracket in the middle to prevent
the pipe from sagging. Local pipe such as PVC pipe cannot be directly
connected to the soft drain pipe connection port.Be sure to use the attached
soft drain pipe . Tighten the hose clamp with a torque of 1.0 to 1.2 Nm.

Test run
Caution Work with the circuit board cover attached.
Using something such as a tester, check whether single-phase 220-240V/220V,
(50/60Hz) power supply voltage is supplied to the drain up kit. Do not splash
water onto the drain up motor.
Drainage check
Check that the pump operates and drains. When draining, check that there is no
water
leakage from the pipe.
(1)Remove the front cover of the drain up kit and pour water into the drain
pan until the drain pan is about half-full of water.
(2)Turn on the drain up kit power supply and check that the drain up process
works normally and the drain water flow is smooth.

Installation of casing
Cut out and remove the covering of the casing pipe outlet with something such
as a cutter.
Install the casing as shown in the figure below and secure it with the fixing
screws and washers.Use the 1 accessory screw and washer when securing the

Are the indoor unit and drain up kit level?
Is the drain pipe pointing downward? (1/50 to 1/100)
Is the drain pipe securely connected? Is there any risk of water leakage?
Is the drain hose insulated properly? Is all the wiring correct?
After the air conditioner test run, perform cooling operation and check the operating sound coming from the drain up kit.
Precautions when operating
The pump will repeatedly stop and start operating due to the action of the
cooling operation float switch.
After cooling operation is stopped, remaining water needs to be discharged, so
do not turn off the power supply immediately.
If turning off the power supply, be sure to wait at least 5 minutes after
stopping operation.If the power supply is not turned off, the drain pump will
stop after about 20 minutes of residual operation.If the safety circuit is
activated, the operation of the air conditioner will stop.
If water leaks from the inside of the air conditioner or the drain up kit
during cooling operation, stop operation immediately.The drain outlet may be
clogged or the safety circuit may not be working properly, so contact your
dealer.
