HOW TO USE
HOW TO USE
Preparation before Operation
● “Transportation” and “Evacuation of the air
in the cylinder” should be done in view of
the following environment of usage.
① Do not use the machine in rain or in areas
where water may enter into the machine.
A fan is built into the machine for cooling
and it may suck water.
② The recovery machine should be used in a
well-ventilated area.
When the machine is used in a poor
ventilated area, you may be choked from
lack of oxygen in case of refrigerant leak.
③ Keep fire away to prevent phosgene (highly
toxic substance) being generated.
④ Combustible gases (hydrocarbon system)
cannot be recovered.
I f a n y c o m b u s t i b l e g a s e s [ a m m o n i a ,
hydrocarbon (propane, isobutene) and so
on] enter into the recovery machine, it may
catch fire and may explode.
● Please note the following points before use.
① C h e c k t h e t y p e o f r e f r i g e r a n t t o b e
recovered.
② Evacuate the air from the refrigerant
recovery machine, charging hoses and
recovery cylinder (hereinafter called
recovery machine, hoses and cylinder).
③ Install a filter or a filter dryer at the suction
port of the recovery machine.
④ Set the valve to the “⓪ START” position before
starting the recovery machine.
⑤ Abnormal noise may be heard when a large
amount of damp refrigerant enters into the
compressor during liquid recovery.
Throttle the valve on the manifold until the
noise cannot be heard.
⑥ Do not close the valve of the hose or the
valve of the cylinder before stopping the
recovery machine during operation.
The gauge may be damaged.
Close the system side valve of manifold,
turn “OFF” the machine after set the valve
to “⓪ START”.
⑦ The temperature of the cylinder may rise
when the ambient temperature is high or
R410A is recovered.
Lower the temperature and pressure of the
cylinder according to “page 11 4) Helpful
Information” and “page 19 Recovery
Procedure of R410A or When the Pressure
of Refrigerant is High”.
⑧ Do not enter the air into the hoses and the
cylinder.
When the cylinder contains air, evacuate
the air from the vapor valve referring to
the chart of saturation temperature and
pressure.
The air can be evacuated before discharging
the refrigerant.
⑨ Use an oil separator when refrigerant with a
large amount of oil is recovered.
The compressor may be damaged when a
large amount of oil is recovered.
⑩ Do not recover virgin refrigerant.
The compressor may be damaged if virgin
refrigerant is recovered for a long time.
If you need to recover virgin refrigerant, put
some additional oil in the compressor.
⑪ Do not recover from air conditioners in
which any sealant has ever been charged.
The sealant may clog the valves or the
compressor and the recovery machine may
be damaged.
⑫ Do not evacuate the air from the cylinder by
using the recovery machine.
The compressor may be damaged if it is run
for a long time under vacuum.
⑬ When starting the machine, it may not start
unless the pressure in the compressor is
equalized.
Start the machine after equalizing the
p r e s s u r e a t t h e d i s c h a r g e s i d e a n d
the pressure at the suction side of the
compressor according to “page 20 How to
Restart the Recovery Machine”.
1）Environment of Usage
● All connections between the recovery machine and the cylinder should be disconnected during
transportation.
◆ All connections between the recovery machine and the cylinder should be disconnected
during transportation.
◆ Steer clear of injuries when you carry a heavy cylinder.
