SAFETY PRECAUTION
CAUTIONS RELATED TO NEW REFRIGERANT
Cautions for units utilizing refrigerant R407C
Do not use the existing refrigerant piping.
Do not use a refrigerant other than R407C.
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.
If another refrigerant (R22, etc.) is used, the chlorine in the
refrigerant may cause the lubricant deterioration.
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 indoors, and both ends of the
piping sealed until just before brazing.
(Leave elbow joints, etc. in their packaging.)
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.
If large amount of mineral oil enters, that can cause
deterioration of refrigerant oil etc.
Use liquid refrigerant to charge the system.
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.
Use the specified refrigerant only.
Never use any refrigerant other than that specified.
Doing so may cause a burst, an explosion, or fire when the
unit is being used, serviced, or disposed of.
Correct refrigerant is specified in the manuals and on the
spec labels provided with our products.
We will not be held responsible for mechanical failure,
system malfunction, unit breakdown or accidents caused
by failure to follow the instructions.
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
If gas refrigerant is used to seal the system, the composition
of the refrigerant in the cylinder will change and performance
may drop.

[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.
[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)
Unit
Gravimeter
(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
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 the following tools specifically designed for
use with R410A refrigerant.
The following tools are necessary to use R410A refrigerant.
Gauge manifold
Charge hose
Gas leak detector
Torque wrench
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.
Tools for R410A
Flare tool
Size adjustment gauge
Vacuum pump adaptor
Electronic refrigerant
charging scale
Handle tools with care.
Store the piping indoors, and both ends of the
piping sealed until just before brazing.
(Leave elbow joints, etc. in their packaging.)
If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
If dirt, dust or moisture enters into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
Do not use a charging cylinder.
The refrigerant oil applied to flare and flange
connections must be ester oil, ether oil or
alkylbenzene oil in a small amount.
If large amount of mineral oil enters, that can cause deterioration of refrigerant oil etc.
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.
If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered.
Use the specified refrigerant only.
Never use any refrigerant other than that specified.
Doing so may cause a burst, an explosion, or fire when the
unit is being used, serviced, or disposed of.
Correct refrigerant is specified in the manuals and on the
spec labels provided with our products.
We will not be held responsible for mechanical failure,
system malfunction, unit breakdown or accidents caused
by failure to follow the instructions.
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
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.

[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.)

1 Operation summary of the linear expansion valve
• Linear expansion valve opens/closes through stepping motor after receiving the pulse signal from the indoor controller board.
• Valve position can be changed in proportion to the number of pulse signal.

The output pulse shifts in above order.
• When linear expansion valve operation stops, all output phase
become OFF.
• At phase interruption or when phase does not shift in order, motor
does not rotate smoothly and motor will lock and vibrate.
• When the switch is turned on, 2200 pulse closing valve signal will
be sent till it goes to point A in order to define the valve position.
• When the valve moves smoothly, there is no noise or vibration
occurring from the linear expansion valves : however, when the
pulse number moves from E to A or when the valve is locked,
more noise can be heard than in a normal situation.
• Noise can be detected by placing the ear against the screw driver
handle while putting the screw driver tip to the linear expansion
valve.
