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 re away to prevent phosgene (highly
toxic substance) being generated.
④ Combustible gases (hydrocarbon system)
cannot be recovered.
If any combustible gases [ammonia,
hydrocarbon (propane, isobutene) and so
on] enter into the recovery machine, it may
catch re and may explode.
● Please note the following points before use.
① Check the type of refrigerant to be
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 lter or a lter 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
pressure at the discharge side and
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.
2）Transportation
CAUTION

ECOsaver V240SP
11
● Use our original recovery cylinders.
● Use cylinders on which the type of refrigerant to be recovered is mentioned.
● Empty cylinders should be evacuated before use.
● How to evacuate air (Vacuum pump is optional)
① Connect the suction port of the vacuum pump
to the vapor port of the cylinder with a hose.
② Switch on the vacuum pump.
③ Close the liquid port of the cylinder and open
the vapor port.
④ Close the vapor port of the cylinder when
the vacuum reaches -72cmHg/-28inHg to
-76cmHg/-30inHg.
⑤ Switch o󱐯 the vacuum pump.
⑥ Disconnect the hose between the vacuum pump
and the cylinder.

● How to shorten the recovery time
① After liquid recovery is completed, recover
from both the liquid and the vapor ports.
② Remove the valve cores of the service ports
of the system if they have.
③ Remove the core depressors of the charging
hoses.
④ Use large size 3/8” hoses.
⑤ Replace the gaskets of the hoses if they are
deformed.
⑥ Recover refrigerant while operating the
crank case heater of the system.
⑦ Heat up the accumulator by a heat gun or
give it vibration if it is frozen.
⑧ Recover from multiple systems in one time.
● How to avoid rise in temperature and
pressure in the cylinder
① Put the recovery machine in a well-
ventilated shady area.
② Do not put the recovery machine and the
cylinder directly on the floor but put them
away from the oor.
③ Cool down the cylinder with wet cloths.
④ Use Cooling Unit (optional accessory) (See
page 19).
⑤ Reduce the suction pressure of the recovery
machine (See page 19).
⑥ Replace the cylinder with an empty one.
⑦ Cool down the cylinder with the sub-cooling
procedure (See page 19).
⑧ Use a 120L cylinder.

● Recover from the high pressure side of the system in case of liquid recovery and recover from the
low pressure side in case of vapor recovery.
● Recover from the high pressure side (liquid refrigerant) when a large volume of refrigerant (5kg
or more) is recovered in one time.

HOW TO USE
Push/PullRecoveryProcedure
● This method is recommended for recovery from a system which has a large amount of refrigerant
(5kg or more).
● Recovery time can be reduced by recovering the liquid refrigerant in the system to the cylinder
and then recovering the remaining refrigerant in vapor.
● This method cannot be applied to the following systems.
・ Refrigeration and air-conditioning systems whose refrigerant volume is less than 5kg.
・ Systems which have a heat pump or a solenoid valve.
・ Systems which have an accumulator.
● There are some other cases to which this method cannot be applied.
Ask the manufacturer of the system if not clear.

RecoveryProcedureofR410AorWhenthePressureofRefrigerantisHigh
● Reduce the suction pressure when R410A is
recovered at high ambient temperature.
● The recovery machine may not stop
automatically if the suction pressure is
20.4kg/cm2 /290psi or more.
In that case, stop the recovery machine
manually after confirming that the low
pressure gauge indicates 0kg/cm2 /0psi or
less.
1）Regulatethesuctionpressure
● Follow the following procedure when R410A or refrigerant at high pressure by heat is recovered.
See “Liquid/Vapor Recovery Procedure” for the standard operation.
● The following procedure is to cool down (sub-cool) the refrigerant in the cylinder instead of
putting the cylinder in water.
2）Cooldownthecylinder(Sub-cooling)
① Connect the hoses as above and recover
refrigerant.
② Set the valve of the recovery machine to the
“⓪ START” position when the temperature and
the pressure in the cylinder rise.
③ Close both the high and the low pressure
side valves of the manifold.
④ Open the vapor valve of the cylinder.
⑤
Turn the valve slowly to the “②VAPOR RECOVERY”
position.
＊ Adjust suction pressure with valve to
3 ～ 5 kg/cm2／ 43.5 ～ 72.5psi.
⑥ Close the vapor valve of the cylinder when
the pressure in the cylinder drops (reduce
the discharge pressure by 2kg/cm2 /29psi a
or more).
⑦ Set the valve of the recovery machine to the
“⓪ START”.
⑧ Open the high pressure side valve or the
low pressure side valve of the manifold and
continue recovery.
◆ Noncondensablesubstance(air)mayexistinthecylinderwhenthetemperatureofthe
