7.7 Assembling the valve

7.7.1 Installing the valve in the system
Faulty assembly of plug screws and lines!
Improperly fastened plug screws and lines may become loose during subsequent
operation and may be ejected due to the pressure. This may cause severe injuries!
▶ Only pressurize your system after all plug screws and lines have been completely
and properly mounted according to the specification.
Faulty mounting!
Mounting of the valve with valve mounting screws of reduced
stability, insufficient mounting or fastening at blocks and plates with
insufficient stability may lead to the valve becoming loose and falling down.
Consequently, hydraulic fluid may leak and lead to personal injuries and/or
damage to property. Particular caution applies to valves with suspended
installation.
▶ Completely assemble the valve according to the assembly specifications
by means of suitable assembly aids.
▶ Only assemble the valve at blocks or plates suitable for the weight of the valve.
▶ Observe the tightening torques, screw stability and the minimum length of the
valve mounting screws.
Insufficient installation space!
Insufficient installation space may lead to jamming or abrasions in case of actuation
and adjustment work at the valve.
▶ Provide for sufficient installation space.
▶ Ensure that actuation, adjustment elements and plug-in connectors are easily
accessible.
Leaking hydraulic fluid!
Hydraulic fluid may leak during assembly and disassembly of the valve. This might
cause persons to slip or fall.
▶ Do not remove the protective caps of the valve until assembly.
▶ After disassembly, seal the hydraulic fluid bores with suitable cap elements.
▶ Immediately remove hydraulic fluid that has leaked out.
