Safety Instructions
Appropriate Use
 The change-over valve is exclusively designed for use in
centralized lubrication systems.
 Do not exceed the maximum ratings mentioned in the
Technical Data, particularly the maximum operating
pressure.
 Any other use will not be conform.
 The manuafacturer is not responsible for damage resulting
from incorrect use.
Maintenance and Repairs
 Before executing maintenance and repair work at the
change-over valve read the Owner s Manual and the
Safety Instructions.
 The Owner s Manual must be available at the place where
the unit is in operation.
 Alterations or modifications of the change-over valve are
only allowed if approved by the manufacturer.
 Use only original spare parts for repair work.
 If other parts are used, the manufacturer may be released
from his liability for the resulting damage.
Operation of the Change-over va ve
 The change-over valve should be used only if it is in a good
state.
 Defects which impair the function and the safety must be
remedied to immediately.
 The function of the change-over valve is only guaranteed if
clean hydraulic oil and lubricant are used.
 If you require more information than mentioned in this
Owner s Manual, Please contact us (see address at the
bottom of the page).
Structure and Mode of Operation
The change-over valve operates like a hydraulically operated
4/2-way valve which alternately discharges the lubricant fed
by the pump into one of both main lines, while the other main
line is connected to the return line connection of the pump.

Erection and Assembly
Requirements on the insta ation site:
 even, solid and vibration-free installation site
 protected from dust and dirt
 safe from atmospheric influences
 position of installation: any
E ectric connection
 Before connecting the unit, disconnect
the system from the power supply.
 The assembly and installation of electri-
cal devices should be carried out only by
an electrician!
 Observe the relevant rules of engineering
and the respective safety provisions
(rules, standards).
 Perform the electrical connection of the
solenoid in accordance with the
connection diagram.
CAUTION
Operating Instructions
Putting into operation
 After connection of the tube lines and the electric lines, the
change-over valve is ready for operation.
Maintenance and repairs
 Repair work should be carried out only by qualified person-
nel using original replacement parts. Provided that only
clean lubricant is used, the change-over valve does not
need any particular maintenance.
The reversing piston is subject to natural wear which de-
pends on the operating time and the adjusted operating
pressure. For repairs, the complete reversing block must
be replaced because the piston is fit to precise tolerances
in the factory.
Before carrying out e ectrica repair
work at the change-over va ve,
p ease observe the fo owing:
* Disconnect the system from the
power supply and take the necessary
measures to avoid it being switched
on again by accident.
* Reduce the system pressure to zero
* Risk of lubricant splashing off
