Owner manual

 The pumps must not start against
pressure. This also applies when
the pump restarts after the power
has been cut off for a short period.
The components to be connected
to the pump must be designed to
withstand the pneumatic data of
the pumps (see Section 8).
The maximum permissible opera-
ting pressure (1 bar g) must not be
exceeded.
 To prevent the maximum permis-
sible operating pressure being
exceeded, restriction or control of
the air or gas flow should only be
carried out in the suction line.
 If restriction or control of the air or
gas flow is made on the pressure
side ensure that the maximum per-
missible operating pressure is not
exceeded.
 When the pump is at a standstill
the inlet and the outlet must be at
normal atmospheric pressure.
Ensure the pump outlet is not clo-
sed or restricted.
 Diaphragm and valve plates are the
only parts subject to wear. Wear is
usually indicated by a drastic
reduction in the pneumatic perfor-
mance. When replacing parts pro-
ceed as described in section 5.
 Ambient conditions: see chapter
1.3.
4.2 Operation
Taking the pump into operation
 Plug the mains plug of the pump
into a properly installed safety
socket.
 Switch the pump on at the pump
mains switch (see fig. 1).
 If cyclic drying of the pump heads
is required in the current evacu-
ation process, switch the drying
system on at the mains switch of
the control (not included in
scope of delivery).
 The drying system should only
be switched on if a container
has been attached to the pres-
sure line of the pump which will
catch the condensate; other-
wise the condensate will flow
out uncontrolled.
Check:
 Tubing for correct tubing.
 Electrical connections for correct
connection.
After the evacuation/process has been
completed, take the pump out of ope-
ration:
 Purge the pump including the
connecting hoses with air at full
flow rate for about 5 minutes.
 If the drying system is switched
on:
Switch the drying system off at the
mains switch of control system
(not included in scope of delivery).
 Switch the pump off at the mains
switch of the pump.
 Pull the mains plug of the pump out
of the socket.
5. Servicing:
Changing Diaphragms and Valve
Plates/Sealings
The structured diaphragms in both
pump heads should be changed at the
same time. When diaphragms are
changed, valve plates/sealings should
also be replaced. If the diaphragms are
not changed in both heads at the same
time or diaphragms and valve plates/
sealings are not changed at the same
time the nominal performance of the
pump is not guaranteed after the servi-
ce.
If a pump has been used for
aggressive or toxic substances or
other types of substances which
are hazardous, hazardous to health,
or injurious, the following points
must be observed:
1.) Clean the pump and its compo-
