Steps for setting into operation
The following procedures have to be done before setting into operation:
1.
Before setting into operation check the proper condition of the electric ca-
bles and connections of the control (Check the cable connections for fixed
fit).
2.
Check the compressed air adapters. The distribution of compressed air
must be supplied with 94 psi (6.5 kg/cm
2
) / Special 50.7
– 116 psi (3.5 – 8
kg/cm
2
), check with pressure gauge. Check before setting into operation
whether the distribution of compressed air, the solenoid valve and the
pneumatic cylinder (drive of the flushing disc) are properly supplied with
compressed air.
3.
Check the differential pressure connection (DDS/DDT). The differential
pressure hoses/pipes (Fig. 9-1 resp. Fig. 9-3 / 9) must be attached to the
intended pressure measuring points (Fig. 9-1 resp. Fig. 9-3 / 7a, 7b) in the
lower region of the filter (inlet), as well as to the appertained differential
pressure switch (Fig. 9-1 resp. Fig. 9-3 / 8a, 8b). The differential pressure
switch must be duly aired out by means of the vent screws (Fig. 9-1 resp.
Fig. 9-3 / 8c). The same applies at a special design with a differential pres-
sure transmitter for a differential pressure registration.
In case of ATEX-specification the deaeration of the measurement pipes
takes place by two separate valves, connected upstream of the differential
pressure switch.
No operation without control
In order to avoid damage to the filter, the strainer insert and the plant, never op-
erate the filter without the control!
The operation without liquid is not damaging the filter. At emptying from pipes
therefore it is not necessary to set the filter out of operation for its own protec-
tion.
