Description

The 755E6 Vacuum Machine designed for fabrication of thin-walled lamination casts with uniform wall thickness as
well as deep-draw work.
The electric connection consists of a 2-meter power cord with a Schuko plug.
The vacuum machine is comprised of two vacuum circuits, which are to be controlled individually. Each vacuum circuit
is provided with one contact pressure gauge and three connections. The connections are secured via input filters and
controlled by valves.
The operational range can be adjusted between 10 % and 78 % (220 mbar). The difference between the switching-
on and switching-off points of the switching automatics is 10 %. If the contact pressure gauge is adjusted to more
than 78 %, then the vacuum machine will remain in continuous operation. The maximum power output is 220 mbar.
Exhausted air is withdrawn via a connecting sleeve on the rear of the unit. Exhausted air can be withdrawn with con-
nected rubber hose into evacuation system.
The basic equipment includes 10 m PVC hose and 17-mm fork wrench for filter replacement.
6 Instructions for Initial Operation (Fig. 1)
Important: Please follow the instructions on the checklist prior to the first operation of this device! Make sure
the power mains and specified system voltage conform to each other !
The vacuum machine must be installed horizontally, otherwise the water trap can operate permanently or trigger the
alarm too late, causing the pump will take in the water and be damaged.
Do not expose the device to direct sunshine. It could also set off the failure alarm.
