Take the red high-pressure hose HP; remove the rapid coupling at its end,
connect the hose to an external cylinder containing refrigerant and carry out
the recovery procedure (see the section Manual operation “RECOVERY”).
If the external cylinder is not equipped with an internal pick-up
tube, it should be turned upside down so that the gas flows out in
a liquid state. We would recommend that the pressure value be
maintained at approximately 3 bar at this stage of recovery visible
on the HP pressure gauge by partially opening the valve on the
external cylinder . When the desired quantity has been reached, close the
valve of the external bottle and wait for the end of recovery operation. Then
disconnect the hose and re-screw the rapid coupling.
To carry out emptying of the cylinder the operator should:
- Switch on the machine, connect a service hose with the
Ref. Service valve and the other
end of the hose with a bottle or another external container; open the valves.
- Once the transfer has come to an end, close the valves and carry out the recovery
operation of the gas left in the hose.
- Check the oil level in the vacuum pump every three months.
- Change the oil in the vacuum pump every six months even when the unit is not used regularly.
- Check the calibration of the scale.
To top up or change oil in the vacuum pump, the operator should use oils that are designed
for use in vacuum pumps.
To top up , the operator should unscrew the cap of the vent (see
illustration) and top up with sufficient oil to the level of the screw of
the indicator light. Finally, replace the cap on the vent.
To do a complete oil change it is necessary to:
- run the pump for 10 minutes;
- disconnect the machine from the power supply;
- disassemble the drainage cap positioned on the underside of the
pump; wait until all the oil has drained out, and replace the cap;
- unscrew the vent cap and fill up with new oil until the level is
halfway up the spyglass;
- replace the vent cap.

15.1 Topping up or changing oil in the vacuum pump
Periodically:
The station is equipped with a recovery cycle counter; when the filters
are saturated, every time the unit is switched on, a display with the
word “FILT” will indicate that they need to be changed shortly.
