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.

Use ESTER , ETHER or HAB as the lubricant to
coat flares and flange connection parts.

If large amount of mineral oil enter, 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.

[1] Cautions for service

Gravimeter

Unit

·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.

[2] 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.

[3] 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)

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

CAUTIONS RELATED TO NEW REFRIGERANT

Use new refrigerant pipes.

Make sure that the inside and outside of refrige­rant piping is clean and it has no contamination
such as sulfur hazardous for use, oxides, dirt,
shaving particles, etc.
In addition, use pipes with specified thickness.

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.

In case of using the existing pipes for R22, be careful with
the followings.

· For RP100, 125 and 140, be sure to perform replace­ ment operation before test run.

· Change flare nut to the one provided with this product.
Use a newly flared pipe.

· Avoid using thin pipes.

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 refrige­rant 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 enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of com­pressor.

Do not use a charging cylinder.

If a charging cylinder is used, the composition of refrigera­nt will change and the efficiency will be lowered.

Tools for R410A

Contamination inside refrigerant piping can cause deterio­ration of refrigerant oil etc.

If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of com­pressor.

If large amount of mineral oil enter, that can cause deterio­ration of refrigerant oil etc.

Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.

Cautions for units utilising refrigerant R410A

[1] Cautions for service

(1) Perform service after collecting 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.)
