Important:
Service and maintenance:
Diaphragms loose seal compression
in the course of time. After valve
assembly / disassembly check that
the bolts and nuts on the body are
tight and retighten as necessary (at
the very latest after the fi rst sterilisa-
tion process). Bolt tightness / valve
sealing should be checked on a
regular basis and points 6-7 of
chapter 12.4 should be repeated.
13 Commissioning
WARNING
Corrosive chemicals!
Risk of caustic burns!
®
Check the tightness of the
G
media connections prior to
commissioning!
Use only the appropriate
G
protective gear when
performing the tightness
check.
WARNING
Protect against leakage!
Provide precautionary measures
G
against exceeding the maximum
permitted pressures caused by
pressure surges (water hammer).
Prior to cleaning or commissioning the
plant:
Check the tightness and the function of
G
the valve (close and reopen the valve).
If the plant is new and after repairs rinse
G
the piping system with a fully opened
valve (to remove any harmful foreign
matter).
Cleaning:
The plant operator is responsible for

selecting the cleaning material and
performing the procedure.
14 Inspection and servicing
The equipment is subject to pressure!
Risk of severe injury or death!
®
Only work on depressurized plant.
G
Hot plant components!
Risk of burns!
®
Only work on plant that has
G
cooled down.
Servicing and maintenance work
G
may only be performed by trained
specialised staff . Death or serious
injury can occur if untrained people
attempt to disassemble any GEMÜ part
or otherwise take measures respecting
the valve for which they lack training.
GEMÜ shall assume no liability
G
whatsoever for damages caused
by improper handling or third-party
actions.
In case of doubt, contact GEMÜ before
G
commissioning.
1. Use appropriate protective gear as
specifi ed in plant operator's guidelines.
2. Shut off plant or plant component.
3. Secure against re-commissioning.
4. Depressurize the plant or plant
component.
The operator must carry out regular visual
examination of the valves dependent on
the operating conditions and the potential
danger in order to prevent leakage and
damage. The valve also has to be dis-
assembled in the corresponding inter-
vals and checked for wear (see chapter 12
"Assembly / Disassembly of spare parts").
