LEAK CHECK
Risk of burning or fire.
Serious burns to the skin or damage to property.
Do not use an open flame to check for function!
Leak check before start-up
Before start-up, check the product connections for leaks!
1. Close all shut-off fittings on the connected devices.
2. Slowly open the withdrawal valve or the gas cylinder valve(s).
3. If there is a safety device (e.g. EFV) between the tank and the connected device(s),
open this during the leak check.
4. Spray all connections with a foam producing substance according to EN 14291
(e.g. leak detector spray, Part no. 02 601 00).
5. Bubbles will form in the foam producing substance if there are any leaks.
If bubbles form, tighten the connections (see ASSEMBLY). If the leaks cannot be
repaired, the product must not be used.
For testing at the test connection, we recommend the leak and function tester type DFP25
(Part no. 02 617 05).
