2SAFETY PRECAUTION
[1] Cautions for 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.
Cautions for units utilizing refrigerant R407C
CAUTIONS RELATED TO NEW REFRIGERANT
Do not use the existing refrigerant piping.
The old refrigerant and lubricant in the existing piping
contain 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.
Use ESTR , ETHER or HAB as the lubricant to
coat flares and flange connection parts.
If large amount of mineral oil enters, that can cause
deterioration of refrigerant oil etc.
Use liquid refrigerant to charge 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.
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. Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.

[3] Service tools
Use the below service tools as exclusive tools for R407C refrigerant.
[2] Refrigerant recharging
(1) Refrigerant recharging process
1Direct charging from the cylinder.
·R407C cylinder 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.

Cautions for units utilizing refrigerant R410A
Store the piping to be used during installation
indoors and keep both ends of the piping sealed
until just before brazing. (Leave elbow joints, etc.
in their packaging.)
Use ester oil, ether oil or alkylbenzene oil (small
amount) as the refrigerant oil applied to flares
and flange connections.
Charge refrigerant from liquid phase of gas
cylinder.
If the refrigerant is charged from gas phase, composition
change may occur in refrigerant and the efficiency will be
lowered.
Do not use refrigerant other than R410A.
If other refrigerant (R22 etc.) is used, chlorine in refrige-
rant can cause deterioration of refrigerant oil etc.
Use a vacuum pump with a reverse flow check
valve.
Vacuum pump oil may flow back into refrigerant cycle and
that can cause deterioration of refrigerant oil etc.
Use the following tools specifically designed for
use with R410A refrigerant.
The following tools are necessary to use R410A refrigerant.
Keep the tools with care.
If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of com-
pressor.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of refrigera-
nt will change and the efficiency will be lowered.

ration of refrigerant oil etc.
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.

[1] Cautions for service
(1) Perform service after recovering the refrigerant left in unit completely.
(2) Do not release refrigerant in the air.
(3) After completing service, charge the cycle with specified amount of refrigerant.
(4) When performing service, install a filter drier simultaneously.
Be sure to use a filter drier for new refrigerant.
[2] Additional refrigerant charge
When charging directly from cylinder
· Check that cylinder for R410A on the market is syphon type.
· Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)
