1SAFETY 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.

[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.
[1] Service tools
Use the below service tools as exclusive tools for R407C refrigerant.
No. Tool name Specifications
1Gauge manifold ·Only for R407C.
·Use the existing fitting SPECIFICATIONS. (UNF7/16)
·Use high-tension side pressure of 3.43MPa·G or over.
2Charge hose ·Only for R407C.
·Use pressure performance of 5.10MPa·G or over.
3Electronic scale
4Gas leak detector ·Use the detector for R134a or R407C.
5Adapter for reverse flow check. ·Attach on vacuum pump.
6Refrigerant charge base.
7Refrigerant cylinder. ·For R407C ·Top of cylinder (Brown)
·Cylinder with syphon
8Refrigerant 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.
