Commissioning
On no account place the dryer into service or take the dryer out of service
without inerting it beforehand!
Together with air, gaseous natural gas can form an explosive gas mixture
and therefore poses a considerable danger. An explosive atmosphere can
build up especially during commissioning and when replacing the drying
agent. To avoid this, the dryer must be purged with inert gas both before
placing into service well as before taking out of service (e.g. before
maintenance).
Hazard caused by escaping gas!
Never remove any parts of the dryer, or manipulate the same in any way,
for as long as the plant is still running! Any sudden escape of gas can
lead to combustible atmospheres in the area surrounding the dryer.
Before carrying out any work on the dryer, first depressurise the plant.
Requirements for initial start-up
Attention!
The dryer must be taken into operation by trained personnel only!
Untrained personnel does not have the required knowledge. Such
personnel might cause serious faults.
Note:
You can order the initial commissioning and start-up from the
manufacturer and have your personnel trained by the manufacturer.
For the first start-up the following preconditions must have been met:
The line network must be kept free of contamination.
All shutoff valves and customer-installed natural gas inlet and outlet valves are
closed.
Carry out all prescribed tests and checks.
Before start-up, ensure that no tools or other foreign parts have been left lying
in a part of the dryer where they might pose a hazard to the dryer being started
up.
Do not modify the factory settings of the control system in any way without prior
consultation with the manufacturer.
The dryer is correctly sited and installed.
