14 Commissioning
WARNING
Corrosive chemicals!
®
Risk of caustic burns!
G
Check the tightness of the
media connections prior to
commissioning!
G
Use only the appropriate
protective gear when
performing the tightness
check.
CAUTION
Protect against leakage!
G
Provide precautionary measures
against exceeding the maximum
permitted pressures caused by
pressure surges (water hammer).
Prior to cleaning or commissioning the
plant:
G
Check the tightness and the function of
the diaphragm valve (close and reopen
the diaphragm valve).
G
If the plant is new and after repairs rinse
the piping system with a fully opened
diaphragm valve (to remove any harmful
foreign matter).
Cleaning:
The plant operator is responsible for
selecting the cleaning material and
performing the procedure.
Important:
Service and maintenance:
Diaphragms degrade in the course
of time. After valve disassembly /
assembly check that the bolts and
nuts on the body are tight and
retighten as necessary (at the very
latest after the first sterilisation
process).
15 Inspection and servicing
WARNING
The equipment is subject to pressure!
®
Risk of severe injury or death!
G
Only work on depressurized plant.
CAUTION
Hot plant components!
®
Risk of burns!
G
Only work on plant that has
cooled down.
CAUTION
G
Servicing and maintenance work may
only be performed by trained personnel.
G
GEMÜ shall assume no liability
whatsoever for damages caused
by improper handling or third-party
actions.
G
In case of doubt, contact GEMÜ before
commissioning.
1. Use appropriate protective gear as
specified in plant operator's guidelines.
2. Shut off plant or plant component.
3. Secure against recommissioning.
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
disassembled in the corresponding intervals
and checked for wear (see chapter 12
"Assembly / disassembly of spare parts").
Important:
Service and maintenance:
Dependent on the operating
conditions, regrease the threaded
spindle.
GEMÜ recommends the grease
"TUNGREASE DAB" from TUNAP.
