SAFETY PRECAUTION

Cautions for using with the outdoor unit which adopts R407C refrigerant.

· Do not use the existing refrigerant piping.

-The old refrigerant and lubricant in the existing piping contains a large amount of chlorine which may cause the lubricant deterioration of the new unit.

· 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 lubricant will result.

· Store the piping to be used during installation indoors with keep both ends 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 ESTR , ETHER or HAB as the lubricant to coat flares and flange connection parts.

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 R407C.

-If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the lubricant deterioration.

· Use a vacuum pump with a reverse flow check valve.

-The vacuum pump oil may flow back into the refrigerant cycle and cause the lubricant deterioration.

[1] Service tools

·Use high-tension side pressure of 3.43MPa·G or over.

2 Charge hose ·Only for R407C.

·Use pressure performance of 5.10MPa·G or over.

3 Electronic scale 4 Gas leak detector ·Use the detector for R134a or R407C. 5 Adapter for reverse flow check. ·Attach on vacuum pump. 6 Refrigerant charge base. 7 Refrigerant cylinder. ·For R407C ·Top of cylinder (Brown)

·Cylinder with syphon

8 Refrigerant recovery equipment.

[2] Notice on repair service

·After recovering the all refrigerant in the unit, proceed to working.

·Do not release refrigerant in the air.

·After completing the repair service, recharge the cycle with the specified amount of liquid refrigerant.

[3] Refrigerant recharging

(1) Refrigerant recharging process

1Direct charging from the cylinder.

·R407C cylinder are available on the market has a syphon pipe.

·Leave the syphon pipe cylinder standing and recharge it. (By liquid refrigerant)

(2) Recharge in refrigerant leakage case

·After recovering the all refrigerant in the unit, proceed to working.

·Do not release the refrigerant in the air.

·After completing the repair service, recharge the cycle with the specified amount of liquid refrigerant.

This indicates when the defrost oper-

ation is performed.

CLOCK display

The current time , start time and stop

time can be displayed in ten second intervals by pressing the time switch button. The start time or stop time is always displayed during the timer operation.

In this display example on the bottom left, a condition where all display lamps light is shown for explanation purposes although this differs from actual operation.
