The check is to be carried out as well if the valve is only stored but not used!
For order details of seal kits, refer to chapter 10.6 "Spare parts".
In order to ensure a long life cycle and functionality, include the following activities
in your maintenance schedule for the overall system:
1. De-energize the connection line.
2. Remove coarse dirt from the exterior.
CAUTION! Damage to property and personal injury caused by electrostatic charging!
▶ In order to prevent electrostatic charging, only clean the coil and the mating
connector using a damp cloth.
3. Check all external fittings for completeness and tight seat.
4. Check cable and line entries, plug screw, external earthing connection and
connection line for tight seat.

see chapter 10.6 "Spare parts".
6. Open the terminal box and replace any damaged sealing devices, if required.

leakage. In case of visible corrosion, remove the valve and have it repaired.

wires of the valve solenoid for visible damage. In case of visible damage, remove
the valve and have it repaired.
