Installing and commissioning
The screw vacuum pump S-VSI 100 (51) with water / water heat exchanger must be connected by a
qualified specialist.
For operating and installation follow any relevant national standards that are in operation.
Please read first the operating instructions BA 832-42-EN and pay attention to the sections “Instal-
lation, Commissioning and Maintenance”.
With any work observe the safety instructions described in section “Safety notes for installation,
commissioning and maintenance.
1. Fill surge tank (W
3
) with air to 0.5 bar (g).
2. remove the de-aeration screw (W
6
) on the cooling water circulation.
3. Fill cooling circulation with a water-glysantine mixture in a ratio of (70:30) at the ball cock (W
4
).
4. Fill cooling circulation until the cooling medium discharge at the opening (W
6
), afterwards close this opening
with the de-aeration screw.
5. after that fill the cooling circulation up to a pressure of 1.2 bar (g) (check by means of manometer (W
2
)).
6. Connect circulation pump (W
1
) an let run at the highest level (level I) - (use the included plug, see enclosed
connection diagram).
Voltage: 1 ~ 230 V (50 Hz / 60 Hz)
7. Please check the water pressure at the manometer (W
2
) and if necessary refill cooling medium.
The water pressure must not exceed 1 bar (g) and underrun 0.6 bar (g).
The water pressure should be checked weekly.
9. Connect the plate heat exchanger (PHE) to the cooling water circulation (see connection diagram).
When connecting the plate heat exchanger (PWT), pay attention to the following items:
Lay the piping in a way that no vibrations, impacts, or pulsations can impact the connections and
the whole PWT.
Shut-off valves should be installed in the pipes to be able to put the PWT out of operation without di-
sturbing the connected systems. It is also required to install vent valves in the pipes to ensure the proper
venting of the PWT.
Wash out the pipe systems before putting the PWT into operation.
Design the piping and the arrangement of valves in a way that the PWT cannot run empty if it is swit-
ched off for a short time (operational) to avoid pressure blows when it is started again.
To prevent pollution we recommend installing appropriate filters (mesh size max. 0.1 mm) in the media
inlets.
Caution! Pollutions in the PWT can cause corrosion and, in some applications, also freezing of the
device can occur.
Danger of death if the electrical installation has not been done professionally!
The electrical installation may only be done by a specialist electrician observing En 60204. The opera-
ting company has to provide the main switch.
While operating the screw vacuum pump S-VSI 100 (51) it must be guaranteed, that the circulation
pump (W
1
) is also enabled.
When power-down of the machine it must be guaranteed, that the circulation pump (W
1
) is also
switched off.
