Assemble the cable guide on the opposite side of
the terminal box:
CAUTION
The adapter 1/2" NPT may only be modified when the
solenoid coil is disassembled.
1. Disassemble the solenoid coil, see "6.2 Turning the sole-
noid coil by ±90°".
2. Open the terminal box (internal hexagon, wrench size 3).
3. Remove the blind plug (hexagon, wrench size 22).
4. Disassemble the adapter (hexagon, wrench size 27).
5. Install the adapter at the opposite side, tightening
torque 13...15 Nm.
6. Mount the blind plug, tightening torque 7...9 Nm.

Initial commissioning, re-commissioning

6.5.1 Checking electrical connections /
replacing seals
Electrical connections must be checked for proper condi-
tion by or under the guidance and supervision of a special-
ized electrician before initial commissioning or any recom-
missioning.
Seals are subject to a natural aging process and for this rea-
son, check seals for damages every time the terminal box is
opened and replace them if required. This check has to be
carried out every 3 years from the date of manufacture of
the valve.
For ordering details for seal kits, please refer to "11.3 Avail-
able spare parts" .

6.5.2 Bleeding the hydraulic system
IMPORTANT
Observe the operating instructions of the device and/or sys-
tem into which the valve is installed.
1. Switch the valve several times under operating pres-
sure before placing it into full operation. This will press
out any remaining air from the valve. Thus, mechanical
damage being caused by inadmissibly high acceleration
of the fluid and the control spool is avoided and the life
cycle of the valve is extended.
IMPORTANT
You can also achieve the switching movement of the
control spool necessary for the bleeding procedure by
manual actuation of the manual override. For further
information, see "8.1 Operating the optional manual
override" .
6.5.3 Performing a leak test
Check whether during operation, hydraulic fluid leaks at the
valve or at the connections.

Disassembly

DANGER
Ensure before disassembly that the hydraulic system is
depressurized and the electrical control de-energized.
1. Loosen the electrical connections professionally.
2. Prepare a container for collecting the escaping hydrau-
lic fluid.
3. Only loosen the valve mounting screws using a suit-
able tool.
4. Remove the valve mounting screws and loosen the valve
from the valve contact surface.
5. Collect the escaping hydraulic fluid in the provided con-
tainer and dispose of it properly.
6. If the valve is to be returned to the manufacturer for
repair, close the valve connection surface using the pro-
tective plate supplied or protect it using equivalent pack-
aging in order to avoid contamination and damage.
7. Seal the subplate in order to avoid contamination.
