2. Changing the Pressure Filter Element

Fig. 7: Location of pressure filter

Fig. 7 shows lever for shut-off valve in operation mode (horisontal).

The shut off valve must be closed before changing the filter element.

Procedure for changing the pressure filter element:

1. Turn lever up ( vertical ) thereby closing

the valve and bypassing the filter.Fig. 8.

Remove element and replace.Fig. 10.

Check condition of O-ring. Replace, if

necessary.

Remount filterbowl. Turn counter-clockwise

(CCW).

3. Changing the Suction Filter Element

Fig. 12: Location of suction filters

The suction filters are duplicated.

The element can be replaced only when the suction filter is not in operation.

Procedure for replacement of the suction filter:

1. Make sure the suction filter you want toreplace is not in operation.

Unscrew filter top CCW. Key with: KW30.

4. Setting the Pressure

Fig. 15: Location of pressure relief valve

The pressure relief valve is preset to 45 bar.

Procedure for setting the pressure:

1. Remove plastic cap.Fig. 16.

Fig. 16: Plastic cap being removed

5.

Turn lock nut CCW, KW19, to loosen.

Fig. 17.

With screwdriver, turn screw CW to raise

pressure, CCW to lower pressure.

Turn lock nut CW to tighten.

Replace plastic cap.Fig. 17: Loosening the nut-screw

5. Changing the Pressure Transducer

While changing the transducer the signal is not active.

Fig. 18: Location of pressure transducer

with needle valve shown

Procedure for changing the pressure transducer:

1. Close the needle valve by turning CW,

thereby isolating the transmitter.

Fig. 19.2

Fig. 19: Needle valve being closed

2. Note: On newer systems, the needle valve (2)

shown in Fig. 19, does not exist on all blocks.

While changing the pressure gauge the signal is not active.

Procedure for changing the pressure gauge:

1.

4.

Close the needle valve by turning CW,

thereby isolating the pressure gauge.

The pressure gauge can now be replaced,KW18.Fig. 23.

After replacement, open the needle valve by

turning CCW.
