Maintenance and Servicing
When maintaining these units and having such situations where
personnel could be hurt by moving parts or by live electrical parts
the pump must be isolated by totally disconnecting the electrical supply.
It is imperative that the unit cannot be re-started during the maintenance
operation.
Do not work a pump that is at its normal operating temperature as there
is a danger from hot parts or hot lubricant.
1. Air filtration
The capacity of the pump can become reduced if the air inlet filters
are not maintained correctly.
Filters on the suction side: Mesh Filter (f

be carried out by washing out or by blowing out with compressed air. Replace
filters if contaminated completely.

Filter Cartridge (Optional Extras): The filter cartridge of the vacuum tight
suction filter (ZVF) or dust separator (ZFP) must be cleaned regularly again
depending upon the amount of contamination. Cleaning can be achieved by
washing or by blowing out with compressed air. Replace the filter cartridge if
necessary. The cartridge can be removed completely by undoing the relevant
retaining clips.
2. Lubrication (picture
)
Check the oil level regularly depending upon the operating hours. First oil
change after 500 operating hours (see oil drain plug (K)). Further changes
every 500 - 2000 operating hours. The oil change times should be shortened if
the application is dusty. Drain the oil also from the oil cooler (R) (see oil drain
plug (K
)).

Only oils corresponding to DIN 51 506 group VC / VCL or a synthetic oil (ob-
tainable from Rietschle) should be used. The viscosity must correspond to
ISO-VG 100 according to DIN 51 519.
The recommended Rietschle Oil types are: MULTI-LUBE 100 (mineral oil);
SUPER-LUBE 100 (synthetic oil) (see oil type plate (M)).
When the oil is under a high thermal load, e.g. ambient or suction temperatures over 30°C, unfavourable cooling or operating with increased
speed etc., the oil change time can be extended by using the recommended synthetic oil.
Old and used oil must be disposed of corresponding with the relevant health, safety and environmental laws.
If the oil brand is changed, the old oil must be drained completely from oil separator housing and the oil cooler.
3. Oil separation (picture
)
Extremely blocked filter elements will result in an increased pump temperature and will cause discolouration of the lubricant.
The oil separator elements may become contaminated after a long period of operation which can result in high pump temperature and motor
overload. We therefore recommend to change the filter elements (L) every 2000 operating hours or when the filter back pressure is in excess of
0.7 bar (see back pressure gauge (Y)
To change filters: Remove oil separator covers (t
