7.4.3 Leak test
The following components are required to check for leaks:
pressure gauge, shut-off valve, supply line and quick coupler.
• Check for leaks in the clamping system in the OPEN and CLOSED
positions.
1. Connect the components to the open CLOSED connection in the
following order:
pressure gauge – shut-off valve – quick coupler – supply line.
2. Pressurize the clamping force block.
3. Close the shut-off valve and remove the supply line.
4. Let the clamping force block sit clamped for 24 hours.
5. After 24 hours, the clamping force block is:
– sealed if the pressure gauge indicates a drop in pressure of
less than 0.5 bar.
– leaking if the pressure gauge indicates a drop in pressure of
more than 0.5 bar.
If the clamping system is leaking, check the screws first (e.g., with
Metaflux leak detection spray). Seal any leaking screws.
Once the fittings are sealed, check for leaks and replace if
necessary (see Disassembling and Assembling the Clamping Force
Block ).
