Removing and Inserting the Internal Demister

Simple maintenance on the side of the pump using Maintenance Kit 1
Required tools: Hex. socket screw key SW 4, SW 6 and SW 8, special
pliers for spring clip.
The internal demister (7/7) has been installed in a resiliant frame (7/8). When
it has clogged it will lift itself up periodically at high intake pressures in order
to equalise the resulting pressure difference.
The increased noise level at high intake pressure is thus a sign for a clogged
internal demister.
Depending on the operating conditions the internal demister will have to be
cleaned regularly or it must be exchanged. Cleaning must be performed
using a suitable solvent.
Switch the pump off and drain out the oil (in accordance with Section 5.4).
In order to collect the remaining oil in the oil box we recommend that you lift
the pump up slightly at the side of the motor.
Unscrew the four hex. socket screws (7/3) of the oil box.
Pull the oil box (7/2) out to the front.
Remove the gasket (7/9) of the oil box.
Use a pair of pliers to pull the spring (7/5) out to the front.
Detach the holding frame (7/8) and the internal demister (7/7).
Clean all parts and check them for perfect condition and replace them as
required.
Reassemble in the reverse order.
