Refrigerant Recycle Equipment

The new unit is filled 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 off 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.

HOW TO USE

Preparation Before Operation

◆  Brand-new cylinders have nitrogen inside.
  Evacuation should be done after discharging nitrogen by opening the vapor valve.
◆  Do not evacuate cylinders which contain refrigerant.
  The refrigerant will be discharged to the air and the vacuum pump oil will blow out.

CAUTION

Install the unit according to the following.

① Flat space indoors.

② Lock Casters properly.

③  Keep 1 m or more around the unit for safe operation.

2）Installation of the unit
