Before placing into operation

Important: Before placing the machine into operation, please check

the oil level of the vacuum pump.

Connect and set the gas cylinder (GX only)

The machine features a facility for inert gas ushing allowing pressure-

sensitive products, such as grated cheese, pasta products and salad
etc., to be packed under vacuum.
You will require the following accessories in order to add inert gas to
the vacuum packaging:

1 gas cylinder with foodstuff gas (e.g. N2/CO2 mixture)
1 reducing valve (operating range 0-1.5 bar)
1 hose (table models: hose-Ø
(mobile models: hose-Ø

2 barbed hose ttings

These accessories are not included in the scope of delivery!

CAUTION!!!

Only gas mixtures with a pure oxygen (O2) content of less than 25 %

may be used for gas ushing.

Otherwise, the pump would be at risk of explosion!

Please contact your gas supplier should you have further questions!

Note: The procedures described below for setting the gas pressure
relate to reducing valves sold by us together with the machine.
Consequently, the setting instructions for valves made by other
manufacturers may differ from these instructions and you should
thus contact your sales agent.

Fit the reducing valve to the gas cylinder and open the cylinder’s main
valve. Then slowly set the regulating screw on the valve to approx.

0.5 bar until gas can be heard to escape.

Caution: If the pressure gauge with the regulating screw is turned
over 1.5 bar, this could damage the reducing valve and the machine1.

Connect the hose to the reducing valve and connect the other end

of the hose with the barbed hose tting to the rear of the machine.
Secure the hose with the barbed hose ttings to prevent it slipping.
