HOW TO RELOCATE OR DISPOSE OF THE UNIT

CONCERNING TERMINAL CONNECTION

FOR AN INTERFACE

CAUTION

In case of faulty wiring connection, the indoor unit

stops, and then the run lamp turns on and the timer

lamp blinks.

CAUTION

Incorrect installation may cause problems such as non-cooling,

non-warming, and condensation water leaking into the room.

CAUTION

 During installation, do not lean on the control box or the display, as they

may be damaged.

 Pass the connecting wire securely through the wiring holder. If it passes

on the sensor, it may not detect suction temperature and/or humidity.

Use cables for interconnection wiring to avoid

loosening of the wires.

How to fit the front panel

Close and attachment of the air inler panel

 In order to protect the environment, be sure to pump down

(recovery of refrigerant).

 Pump down is the method of recovering refrigerant from the

indoor unit to the outdoor unit when the pipes are removed

from the unit.

Connect charge hose to service port of outdoor unit.

2 Liquid side : Close the liquid valve with hexagon wrench key.

Gas side : Fully open the gas valve

Carry out cooling operation . (If indoor temperature is low,

operate forced cooling operation.)

3 After low pressure gauge become 0.01MPa, stop cooling

operation and close the gas valve.

1. Open the air inlet panel and remove the air filters.

2. Install the filter holders, with the air-cleaning filters installed in the holders.

In the air conditioner.

• Each air-cleaning filter can be installed in the upper or lower filter holder.

3. Install the air filters and close the inlet panel.

After installation

The power supply voltage is correct as the rating.

No gas leaks from the joints of the operational valve.

Power cables and crossover wires are securely fixed to the terminal board.

Operational valve is fully open.

The pipe joints for indoor and outdoor pipes have been insulated.

 Fitting

1 Do remove the air filter.

2 Cover the body with the front panel.

3 Fit the 6 latches in the lower section.

then 3 latches in the upper section.

4 Tighten the 5 set screws.

5 Fit the air filter.

6 Fit the air inlet panel.

 To close, attach the panel after pulling

the strings, hold the panel at both ends of

upper part to lower downward and push it

slightly until the latch works.

Preparation of indoor unit

Installing the air-cleaning filtersConcealed installation

1 Remove the fixing screw of clamp.

2 Connect the connecting wire securely to the terminal block.

1 ) Connect the connection wire securely to the terminal

block. If the wire is not affixed completely, contact will be

poor, and it is dangerous as the terminal block may heat

up and catch fire.

2 ) Take care not to confuse the terminal numbers for indoor

and outdoor connections.

3 Fix the connecting wire by wiring clamp.

4 Pass the connecting wire through the wiring holder.

Install the indoor unit according to the following instructions.

1 Secure the upper, right, and left spaces according to the right figure.

2 Do not let the horizontal bar obstruct wind from blowing out

upward/downward or reception from the remote controller.

3 The lattice size should be 70 % or greater of the open rate.

4 Cut the jumper cable (JP173) on the indoor circuit board to control

the blow-out angle.

Mounting of connecting wires

Conventionally, operate the remote control switch by

holding in your hand.

Avoid installing it on a clay wall etc.

INSTALLATION OF REMOTE CONTROL

Mounting method of battery

Fixing to pillar or wall

Do not use new and old batteries together.

Test run

Air conditioning operation is normal.

No abnormal noise.

Water drains smoothly.

Protective functions are not working.

The remote control is normal.

Operation of the unit has been explained to the customer.

(Three-minutes restart preventive timer)

When the air conditioner is restarted or when changing

the operation, the unit will not start operating for

approximately 3 minutes.

This is to protect the unit and it is not a malfunction.

Check the following points again after completion of the installation, and before turning on the power. Conduct a test run again and ensure that the unit operates properly.

At the same time, explain to the customer how to use the unit and how to take care of the unit following the user's manual.

Forced cooling operation

Turn on a power supply again after a while after turn off a power supply.

Then press continually the ON/OFF button 5 seconds or more.

1 Remove the front panel and lid of control.

2 There is a terminal (respectively marked with CNS) for the indoor control board.

In connecting an interface, connect to the respective terminal securely with the connection

harness supplied with an optional “Interface connection kit SC-BIKN-E” and fasten the

connection harness onto the indoor control box with the clamp supplied with the kit.

For more details, please refer to the user's manual of your “Interface connection kit

SC-BIKN-E”.
