ings. It should be able to handle pressures a minimum of
50 mbar with an accuracy of 0.01 mbar minimum.
z
Disconnect the system from the power supply.
z
Check all sections of gas pipework and connections for
signs of leaks before starting up the system for the first
time. If a leak is detected during tightness testing, use an
approved leak detector to check all connections for
possible escapes.
The product must be certified as a gas leak-testing agent.
DO NOT allow the product to come into contact with elec-
trical wiring.
The test pressure of the gas pipe when the gas shutoff valve is
open may not exceed 150 mbar.
