Use
The controller can be used in its bag or out of its bag. The rear pocket allows the hose and the
various couplings to be stored.
Put the battery in position as indicated in the photograph, with the correct polarities.
Ensure that the gas supply to the pipe for testing is turned off.
Close all the end circuit valves (for domestic installations, these are valves of the gas
appliances).
Open all the secondary or intermediate valves.
Screw the appropriate coupling on to the circuit for testing, then connect the controller and its
hose by tightening the knurled parts by hand. (Do not forget to use the supplied joints).
Press the button until the service pressure of the pipe is obtained; the controller automatically
limits the max. pressure to approximately 45mbar*. A 20-litre volume installation is pressurised
in less than 2 minutes.
To refine the test pressure, slightly untighten one of the knurled parts of the hose. Leave to
stabilise for a time, according to the gas used (butane/propane: 10 minutes, network gas: not
recommended)
Place the moving red pointer over the needle of the manometer and wait for 10 minutes.
During this period the black needle must not move from its position at the start of the test. If
this is the case, the installation is considered to be sealed. If a drop in pressure is observed,
there is a leak in the pipe or the checker is improperly connected. Use VIRAX leak detector
Ref. 262630 to locate the leak and repeat the checking operation after repairing the defective
section.
