o
If the pump or its piping on the exhaust side is to be replaced or
removed, after the replacement a tightness test must be carried
out on the fitted pump with 10 bar pressure, in order to ensure the
tightness of the exhaust in the housing. Note the special operating
manual for this purpose.
o
If the installation is to be removed or dismantled, this is only per-
mitted in the gas-free state. After refitting, the earthing / equipo-
tential bonding must be re-established.
7.3 Functional check
Checking of the functional and operational safety and reliability must
be performed:
o
After every start-up,
o
In accordance with the time intervals specified in section 7.2 10 ,
o
Whenever a fault has been rectified.
2 people may be required to perform a functional check, depending
on the design of the pipe or tank. The following content must be noted
or complied with:
- Agreement of work with the responsible operative officer
- Observe the safety information regarding handling of the materials
being stored or conveyed
- Checking and if necessary, emptying condensate traps (7.3.1)
- Continuity test of the interstitial space (7.3.2)
- Testing of the switching values with interstitial space (7.3.3)
or testing of the switching values with test device (7.3.4)
- Testing of the conveying height of the pump (7.3.5)
- Tightness test of the system (section 7.3.6)
- Leak tightness check in the course of the annual functional check
(7.3.7)
- Setting up of the operating state (section 7.3.8)
- Completion of a test report with the confirmation of functional and
operation safety. (Test reports are available for downloading on
the SGB website.)
7.3.1 Checking and if necessary, emptying condensate traps
IMPORTANT: Condensate traps may contain the product being
stored/transported. Take suitable protective measures.
(1) If there are shut-off cocks on the interstitial space side, close
them.
(2) Turn the three-way valves each 180°, so that the connection lines
are ventilated.
(3) Open and empty condensate traps.
