2 SAFETY PRECAUTION
Cautions for devices that use R407C refrigerant.
· Do not use the existing refrigerant piping.
-The old refrigerant and refrigerator oil in the existing piping contains a large amount of chlorine which may cause the
refrigerator oil of the new unit to deteriorate.
· Use “low residual oil piping”.
-If there is a large amount of residual oil (hydraulic oil, etc.) inside the piping and joints, deterioration of the refrigerator oil
will result.
· Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before
brazing. (Store elbows and other joints in a plastic bag.)
-If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result.
· Use Suniso 4GS or 3GS (small amount) as the refrigerator oil to coat flares and flange connection parts.
-The refrigerator oil used with the air conditioner is highly hygroscopic. If it is used, water may be mixed in and deterioration
of the refrigerator oil may result.
· Use liquid refrigerant to seal the system.
-If gas refrigerant is used to seal the system, the composition of the refrigerant in the cylinder will change and performance
may drop.
· Do not use a refrigerant other than R407.
-If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the refrigerator oil to deteriorate.
· Use a vacuum pump with a reverse flow check valve.
-The vacuum pump oil may flow back into the refrigerant cycle and cause the refrigerator oil to deteriorate.

4
[1] Service tools
Use the below service tools as exclusive tools for R407C refrigerant.
No. Tool name Specifications
1 Gauge manifold ·Only for R407C.
·Use the existing fitting SPECIFICATIONS. (UNF7/16)

8 Refrigerant recovery equipment.
[2] Notice on repair service
·After recovering the all refrigerator in the unit, proceed to working.
·Do not release the refrigerant in the air.
·After complete the repair service, recharge the cycle with the specified amount of the
liquid refrigerant.

[3] Refrigerant recharging
(1) Refrigerant recharging process
1Direct enclosure from the bomb.
·Comfirm that R407C bomb on the market are syphon pipe.
·Leave the syphon pipe bomb raising and recharge it.
(By liquid refrigerant)
(2) Recharge in refrigerant leakage case
·After recovering the all refrigerator in the unit, proceed to working.
·Do not release the refrigerant in the air.
·After complete the repair service, recharge the cycle with the specified amount of the
liquid refrigerant.

NOTE : If the operation stops to function of the protection device, the check display flashes.
●
Connect the lead wires accordling to the color indication of sticker on the compressor terminal.
●
Since LD8 lights when normal power is turned “ON”, check the power supply with the “ON” or “OFF” LD8.
❈
Since the transformer (T) is connected with 240V power, if 220V or 230V power is used, change the wiring connection
in the following procedure.
●
Since the indoor and outdoor connecting wires has polarity, make sure to connect the same terminal numbers (1,2,3) for indoor and outdoor units.
How to use SW1 and 2
●
Pressing erases the past check contents loaded on the
microcomputer.
●
The output display (light) remains lit during operation but
pressing displays the past check contents in flashing

Main functions of LED
(
when both Nos.1 and 2 of are “OFF”
)
NOTE : If the operation stops to function of the protection device, the check display flashes.
●
Connect the lead wires accordling to the color indication of sticker on the compressor terminal.
●
Making wiring connection in anti-phase or missing phase “L2” or “L3” 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 “L1” 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
in the following procedure.
●
Since the indoor and outdoor connecting wires has polarity, make sure to connect the same terminal numbers (1,2,3) for indoor and outdoor units.
How to use SW1 and 2
●
Pressing erases the past check contents loaded on the
