7.11.2. Procedure to be followed when replacing a gas bottle
Caution
» Never drop a gas cylinder. During transport, the valves of the gas bottles must be pro-
tected by caps.
»
Use a special vehicle for transportation of these bottles. Always fasten and lock gas
bottles in place.
» Close the aft saloon sliding door tight when exchanging bottles, ensure good ventilati-
on.
Danger
» Be sure that all gas in the system has been burnt off before opening the valve at the
cylinders head.
»
Always wait until the flame has gone out completely, only then will the line be without
pressure.
» If gas does leak whilst the valve at the cylinder is closed and the pressure reducer is not
fitted, then the valve is probably damaged.
» If this is the case, replace the regulator immediately to stop leakage, then call a local
gas supplier. Never disconnect regulator if flame stays lit.
The procedure of changing a gas bottle in single steps:
» Turn off the gas consumers and the engine, turn the valve or switch located on the bottle/ cylinder itself.
»
Disconnect (turn) the pressure regulator from the bottle. Do only use appropriate tools in order not to damage the
fittings.
»
Fit the protective cap promptly on the empty bottle.
»
Remove the protective cap from the fitting of the new gas bottle.
» Loosen the empty bottle and take it out of the tray/box.
» Place the new bottle in the tray/box and fasten it securely.
» Check the connection thread for defects.
» Place the cap nut carefully and fasten hand-tight. Please observe that threads of gas installations often use
different thread types – directions!!
»
Fasten the cap nut with an appropriate tool and check for leaks.
» Check all components again, only then open the valve at the regulator.
» Check the tightness of the system by reading the manometer. The manometer shall not display any pressure drop
with consumers closed.
Inspection of the gas system
Test the LPG system for leakage regularly. Check all connections for leakage by:
1.
Routine checks with a leak detector (if fitted)
2. Manual leak testing
3.
Testing with soapy water or detergent solution (with appliance-burner valves closed and cylinder and system
valves open)
