Caution

Caution: switching of inductive loads (solenoid

coil)

Inductive loads may considerably reduce the

service life of or even destroy contacts.

Preferably a clamping diode should be connec-

ted in parallel to the solenoid coil. The polarity

should be chosen in such a way that the diode

blocks when normal operating voltage is avail-

able.

DANGER

DANGER: cleaning agents

Cleaning agents can be detrimental to

health and environment.

Adhere to the relevant regulations and

take the necessary precautions when

handling cleaning agents and disposing of

them. Consider possible reactions with the

product materials.

•Carefully clean the parts with a grease solving, non-

scouring cleaner.

•After cleaning, the parts should preferably be rinsed

with alcohol and subsequently heated to ≈50 °C in

an oven or with an industrial blower.

•Carefully clean the sealing surfaces with a lint-free

cloth moistened with alcohol. Allow them to dry.

•Wipe the seals with a lint-free cloth slightly

moistened with vacuum oil.

[Proceed in reverse order to reassemble the valve.

After reassembly, a few switching cycles should be

performed in order for the O-rings to perfectly adapt

to the sealing surfaces.
