After the wiring is completed following "How to wire the signal receiving unit" below
without slack of the wires, pull the black pad that covers the wire by approx. 20 mm
out of the rectangular hole on the indoor unit side, and then clamp the wires with the
supplied clamp tightened with the screw. Then return the packing removed from the
rectangular hole on the signal receiving unit to the original position. (Fig. 3)
* Securely position the black pad and fix the packing. Failure to do so may cause water
leakage or dew drop on the unit and wires.

Multiple remote controller installation
The control by two remote controllers is enabled by installing the wireless remote
controller with the wired remote controller for an indoor unit.
(Max. 2 remote controllers of wireless or wired are insatiable.)
"2-remote controllers" controlling means that one or multiple units are operated by the
multiple remote controllers.
Note:
1.
Upon confirmation of the terminal numbers of the indoor unit, connect the control
wire without miswiring. (If applied 220 - 240 V, damage the unit.)
2.
The multiple wireless remote controller kits cannot concurrently be used for an
indoor unit.
3.
When installing simultaneously the wireless remote controller with the wired remote
controller, set one of them as the follower remote controller.
• To use wired remote controller or Lite-vision plus remote controller as a follower,
settings must be changed. For the details, refer to the installation manual of each
controller.
• To use the wireless remote controller as a follower, set bit 4 (Follower side) of DIP
switch SW30 on the signal receiving unit P.C. board to ON.
2-remote controllers
The indoor unit is operated if either wireless or wired remote controller is set as header
or follower remote controller.

Remote controller address (A-B selection) setting
• When two or more signal receiving units are installed in a room, a unique address
can be set for each signal receiving unit to prevent interference.
• Address (A-B selection) must be changed on both signal receiving unit and wireless
remote controller.
• For the details of address change (A-B selection) on wireless remote controller, refer
to the owner's manual.
Turn off the indoor unit power supply. Turn on the bit 4 of DIP switch SW30 on the
signal receiving unit P.C. board.
The setting change is shown below.

Test run (Forced cooling operation)
Requirement:
• Finish the forced cooling operation in a short time because it applies excessive
strength to the air conditioner.
How to perform forced cooling operation
1.
When TEMPORARY button is pushed for 10 seconds or more, "Pi!" sound is heard
and the operation changes to a forced cooling operation. After approx. 3 minutes, a
cooling operation starts forcedly.
Check cool air starts blowing. If the operation does not start, check wiring again.
2.
To stop a test operation, push TEMPORARY button once again (Approx. 1 second).
• Check wiring / piping of the indoor and outdoor units in forced cooling operation.
