Air filter (optional)

The vacuum pump must be protected from particles and liquids by means of suitable filters or
a condenser. These elements must comply with Directive 2014/34/EU: marking II 2 G IIB T4
mini and II 2 D IIIC T135°C mini according to zones.
Depending on the degree of impurities sucked in, the suction filter cartridge will clog. We recommend a
replacement at least every 1000 hours. This frequency must be adapted to suit your pumping application.
Clean the inside of the filter.
For the CHA filter: the weight of the carbon filter gives information on its operating state.

Automatic drain

This drain reinjects the oil from the separating cartridges into the pump. It is located in the separating
cartridge compartment.
Operating check:
Stop the pump. Remove the plate giving access to the compartment of the separating cartridge(s). Add a
1/4 litre of oil to the drain: the float should rise. Start up the pump: the additional 1/4 litre of oil should be
sucked in, the level in the separating cartridge(s) compartment drops.
Maintenance for E65.R / E100.R:
If the operation is correct, no maintenance is necessary.
If the level does not drop after adding oil and restarting the vacuum pump, remove the float; remove the
peg and its seal, clean the hole (blowing), then reassemble the assembly.
Maintenance for E200.R / E300.R:
Remove screws [1] and take the drain assembly
