Simplified leak check
Check for leaks every time you replace a cylinder or if the system has not been used for some
time.
1. Close the cylinder valve on the operating side.
2. Open the cylinder valve on the reserve side.
3. The visual indicator type AUV changes from
GREEN
to
RED
= reserve.
4. Close the open cylinder valve on the reserve side.
The indicator should not change within 15 minutes, otherwise the system has a leak.
The simplified leak testing process does not replace the pressure and leak testing of the LPG
system by a professional.
Test connection for leak tester
A leak tester can be connected to the test connection for pressure and leak testing of the
LPG system.
1. Close all shut-off fittings on the connected
consumption equipment.
2. Open the cylinder valves.
3. Unscrew the screw caps of the test connection
and test valve .
4. Connect the test pump to the test connection
using the test hose.
5. Turn the test valve downwards to the
“OPEN” position using a suitable SW6 tool.
6. Carry out leak testing at max. 150 mbar
.
7. Once the test is complete, turn the test valve
back to the “CLOSED” position.
8. Fasten the screw caps back on + .
9. Check the leak-tightness of the test
connection.
START-UP
After the product has been ASSEMBLED and LEAK TESTING has been carried out
successfully, it is immediately ready for operation.
The product can be damaged if the gas cylinder is moved!
Entrained liquid phase can cause the pressure to increase in the LPG system and damage
the product or the LPG system.
Do not move the gas cylinder while the system is in operation.
If LPG is withdrawn too quickly or is continuously withdrawn from the cylinder on
the operating side, the temperature of the gas falls and, as a result, the cylinder pressure
drops below the required inlet pressure of the regulator. LPG is then also withdrawn from the
reserve cylinder.
Proper operation of the system is no longer guaranteed.
The LPG cylinders on both sides may be emptied simultaneously or also at different
rates.
