Refrigerant Recycle Equipment
The new unit is lled with nitrogen gas to prevent damage during transit.
① Connect the unit to proper power supply.
② Connect Filter to Suction Port.
(Refer to page 8 ③ )
③ Connect Sight Glass to Discharge Port.
④ Open Suction Valve and Discharge Valve.
1）Dischargenitrogengasfromtheunit
3）PreparationofCylinder
Evacuate a cylinder by using a vacuum pump (optional accessories).
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 － 0.095MPa（ － 13.8psi） ～
－ 0.1MPa（－ 14.5psi）.
⑤ Switch o󱐯 the vacuum pump.
⑥ Disconnect the hose between the vacuum pump and the cylinder.
① In case ambient temperature is under 10℃ , the unit needs warming up before operation. Refer to
the page 16, Warm Up Operation. Do not operate at temperature under 5℃ and over 35℃ .
② Filter provided as standard accessory must be installed on Suction Port when operating the unit.
③ Do not recycle following refrigerant with the unit :
・The purity of recycled refrigerant is low and, it may cause damage to the unit.
・Refrigerant charged in a system which the compressor has been burned out.
・Refrigerant which may be mixed with other type of refrigerant.
・Refrigerant which contains sealant.
