The condenser cooling surface must be kept clean:
-
Remove the rear panel of the station (4 screws).
-
Clean the cooling surface with compressed air and perhaps a soft brush. Be
careful not to bend the fins since this would reduce the air flow and impair
condenser capacity.
-
Replace rear panel.
Check the oil level in the vacuum pump:
-
If the oil level is below the centre of the sight glass, replenish as follows:
-
Remove cap (pos. 32) to replenish vacuum pump.
-
Replenish (slowly) with vacuum oil to the correct level.
- Replace
cap.
For each 75 operating hours:
Replacement of filter drier (pos. 5)
-
Remove front panel (6 screws).
-
Remove filter by loosening the pressure control (two 3/8” flare nuts), and
then fit the replacement filter. Always use a new filter fitted with protective
caps on the connectors.
Replacement of filter drier (pos. 8)
-
Remove rear panel (6 screws).
-
Remove filter by loosening the union nuts and the solenoid valve (pos. 36)
at the filter end. Loosen the nuts slowly and take out the filter.
-
Fit a new filter in the station, making sure to retighten the union nuts.
-
Refit pressure control and solenoid valve.
On replacing filter driers a small quantity of refrigerant escapes - therefore
follow the appropriate safety precautions.
