Start-up
CLEARPOINT® L 205 – L295 V
35
Prior to delivery, the CLEARPOINT
®
V is operated dry in the factory. If the activated-carbon adsorber is
not installed immediately after having been delivered, and if it is installed downstream of an adsorption
dryer, it may be necessary to allow dry compressed air to flow through the activated-carbon adsorber for
approximately four to six hours to remove the residual moisture from the activated carbon.
If the activated-carbon adsorber is equipped with a
METPOINT
®
OCV,
the initial start-up should be
implemented without
METPOINT
®
OCV
. To prevent the risk of contaminations through dust, the
METPOINT
®
OCV
should only be installed after a trial run of several hours (for the installation of the
probe, the plant section again needs to be unpressurised).
Subsequent to the successful start-up, no other works are required. The CLEARPOINT
®
V is now ready
to operate. In the event that unexpected failures occur during the running operation, please inform the
service technician who is responsible for you.
14.4 Restart
If the CLEARPOINT
®
V is restarted after a longer down time, proceed as during the initial start-up.
Check, above all after completed maintenance or repair measures, whether the CLEARPOINT
®
V is
completely tubed. If not, carry out proper installation.
14.5 Removal from service
For safety reasons, short-term removal from service should always be implemented together with the
compressor.
For the removal from service during maintenance or repair measures, please proceed as follows:
Unpressurise the plant prior to any maintenance or repair measures!
Open the bypass line (not included in the scope of delivery).
Close the shut-off valves (not included in the scope of delivery) upstream and downstream of the
activated-carbon adsorber.
Unpressurise the activated-carbon adsorber.
Stagnation pressure may occur in pipe sections or in the container due to plugging. It
is imperative to observe the manometer at the container during the pressure
reduction! Ensure that there is no stagnation pressure in pipe sections or in the
container. This is particularly possible if the compressed-air distributor or the filter
element of the afterfilter (not included in the scope of delivery) are blocked as a result
of a large amount of wear debris.
