3.9 De-aerating
De-aerating the gas line by closing the tap for the gas connection and
unscrewing the screw on the measuring nipple for the connection
pressure. Connect a plastic hose, open the tap and discharge the gas
to a safe place. When de-aerating is complete, do not forget to screw
the screw back into the measuring nipple.
3.10 Leakage control
When testing for leaks, the solenoid valve must be closed. Connect a
pressure gauge to the test nipple ”Pa”, see fi gure. The test pressure
in the system must not be higher than max. connection pressure, see
type plate. If leaks are found during measurement, locate the leaky
spot using soapy water or leak detection spray. After sealing, the
system is tested for leaks again.
