CHARGELESS SYSTEM
PRE-CHARGED REFRIGERANT IS SUPPLIED FOR UP TO 30m PIPING LENGTH AT SHIPMENT.
The unique refrigerant circuit and a large accumulator always control the optimal refrigerant level regardless of the length
(50m max. and 5m min.) of piping. The additional refrigerant charging work during installation often causes problems.
Therefore, it is completely eliminated. This unique system improves the quality and reliability of the work done. It also helps
to speed up the installation work.

CAUTIONS FOR SERVICING
●
Connect the lead wires according to the colo indication of sticker on the compressor terminal.
CAUTIONS FOR POWER SUPPLY WIRING
●
Making wiring connection in anti-phase or missing phase “A2” or “A3” causes the protection device incorporated in the
microcomputer to function resulting in LD1 or LD2 shown in the table above to flash and prevents the compressor
operation. If phase “A1” or “N” is missing it causes all displays to go out. Under normal condition LD8 light when power
is turned “ON”. If anti-phase connection is to be used, change connections of 2 out of 3 power lines (field wiring side)
contained in the power supply terminal block (TB1) of the outdoor unit as shown at the right upper.

Since the transformer (T) is connected with 240V power, if 220V or 230V power is used, change the wiring connection

CAUTIONS FOR POWER SUPPLY WIRING
●
Making wiring connection in anti-phase or missing phase “A2” or “A3” causes the protection device incorporated in the
microcomputer to function resulting in LD1 or LD2 shown in the table above to flash and prevents the compressor
operation. If phase “A1” or “N” is missing it causes all displays to go out. Under normal condition LD8 light when power
is turned “ON”. If anti-phase connection is to be used, change connections of 2 out of 3 power lines (field wiring side)
contained in the power supply terminal block (TB1) of the outdoor unit as shown at the right upper.
