Setup
Set up the gas cylinder change-over unit either as a standalone unit or mount it on the wall.
Free standing setup: The attached rubber feet must be stuck on the bottom of the unit.
Wall mounting: The attached fixing flaps must be mounted at the back. The unit
should be used as a stencil for drilling, and bored accordingly. Use
suitable mounting hardware such as dowels and screws.
Power connection
The unit is equipped with a flexible plug-in power cord. The plug disconnects the unit from the
power supply network . Compare the power voltage and nameplate data ( note the position of
voltage selection switch) and plug in the power cord. At delivery, the unit is set up for 230 V . If
required, it can be switched to 115 V operation. To change the input voltage, use a suitable tool
to alter the setting of the red selector switch on the side of the unit. So that the indicated setting,
230 , changes to 115 .
Gas supply connection
The gas supply connections of the gas cylinder change-over unit are designed for pressure hoses
with an inner diameter of 4 mm and a wall thickness of 1 mm. Attach the hose connections bet-
ween the gas cylinder, GM 2 gas cylinder change-over unit and the consumer as specified in the
connection drawing. Cut the supplied hose to appropriate lengths. Connect the supplied hose
nozzles to the pressure reducer and secure the connected hoses with ties.
Only two-stage devices should be employed as cylinder pressure reducers, as these will maintain
a constant output supply pressure.
