DO NOT CHANGE CYLINDERS IN THE PRESENCE OF NAKED LIGHTS.

NEVER USE A MATCH OR NAKED FLAME TO SEARCH FOR LEAKS.

ALEAK WILL SMELL

With no flame on, remove the seal cap on the automatic valve, place the Quick-on onto

the automatic valve and push down firmly and vertically. You will hear a “click” sound

which means the regulator is securely latched (fig. 4).

Note: Quick-on is so designed as to prevent it from being fitted to the valve, unless the

regulator handle is in the closed position; therefore, never attempt to mount or dismount

it, if the handle is not in this position.

the regulator handle upwards (counterclockwise).

To shut off the gas supply, reverse above procedure; an arrow engraved on the handle

indicates the closing direction (fig.3).

Symbols engraved on the bonnet show how to operate the regulator handle.

CAUTION: if you are unable, to open the regulator handle, this means that your Quik-

on is not correctly connected to the valve. Do not force the handle to open, instead start

again the operations described above in 3.

-all taps on the consuming appliance are in the closed position.

-the Quick-on regulator handle is in the closed position.

Then, dismount the Quick-on by pressing horizzontally on the handle ond pulling
