•
Then connect the charging hose (5) to the pressure regulator connection (11).
•
Connect the other end of the charging hose (45° bend) to the marking gauge (4).
•
In this process, ensure that the tap (12) is closed. The yellow handle must be
pointing towards you.
•
Then tighten the connection (13) on the respective refrigeration circuit (14).
•
Now open the gas cylinder valve slowly. The primary gauge (9) will be indicating
the cylinder pressure.
•
Then open the yellow tap (12) on the marking gauge. The tap must be pointing
in the direction of the charging hose.
•
Turn
the handwheel (8) to set the required pressure (10). For washing, set a pressure
between 4 and 7 bar.
•
The system will then be blown out at a constant pressure.

Notes on operation and maintenance
•
Always protect the pressure regulator against damage (visual inspection at regular
intervals).
•
It is not permitted to change the factory setting of the blow-off valve.
•
Make sure that the connection gaskets, sealing surfaces and gauges are in perfect
condition.
•
In the event of any faults, e.g. a rise in the backpressure on removal = 0, with leaks
into the atmosphere, faulty gauges or if the safety valve is triggered, decommission
the pressure regulator and close the cylinder valve immediately.
The test device is very sensitive. In the event of improper use or
impact
, it must be
re-tested by a specialist centre.
