6.1 Installing the pump
Notes on installing the pump
1. Place the pump on a
flat, horizontal surface
.
2. Make sure that the pump is
stable and secure
, with no additional mechanical contact other than
the pump feet.
3. Make sure that the system to be evacuated and all hose connections are
mechanically stable
.
4.
Never install the pump on a soft surface (such as foam)
, as this impairs air supply to the fan.
5. Ensure
adequate air supply
if you install the pump in an enclosed housing or at a high ambient
temperature. Provide external forced ventilation if necessary.
–
Minimum 5 cm
between fan (on pump underside) and adjacent parts (for example housing,
walls, etc.)
6. If you install the pump at an
installation altitude of > 1000 m AMSL
, you must implement
meas-
ures in accordance with DIN VDE 0530
to ensure an adequate cooling air supply.
7.
Anchor
the pump to the supporting surface in the event of stationary installation.
8. Use
elastic hose pieces or bellows
for anchoring.
– This prevents mechanical forces resulting from rigid connection lines.
9. Maintain
ambient conditions
.
10. Before switching on, allow the pump to
acclimatize
.
– If the pump is brought into the operating area from a cold environment, condensation can
form.
6.2 Connecting the pumping stages
NOTICE
Pump damage caused by overpressure
Mixing up the connections causes overpressure overload. The pump can be started only against
max. 1 bar differential pressure between inlet and outlet, otherwise the motor jams and sustains dam-
age.
► Make sure that the distributor is installed correctly on the diaphragm heads, before connecting
the pump to the vacuum equipment.
► Before commissioning, make completely sure that the pressure side pressure is below the per-
missible limit.
The intake connections of the pumps are marked "
IN
" and the outlets "
EX
" on the individual diaphragm
heads.
