6. Functional Checks
After every change of cylinder it is essential to perform a functional check on the pressure
reducer.
If this functional check reveals any faults, you must not use the pressure reducer.
A full functional check comprises:
•
Visual inspection for mechanical damage;
•
"6.2 Checking the system for leaks" on page 22;
•
"6.3 Checking for leaks in the safety valve" on page 23.
We recommend you always have the following spare parts available:
•
Replacement seal set WM 1148;
•
Filter screw WM 30905
6.1 Intervals
