second pump head.
e.) Refitting the pump heads
At one pump head:
Press the lip on the edge of the
structured diaphragm into the
groove in the housing.
Place the intermediate plate ,
with the valve plates/sealings on
the adapter .
Place the head plate on the
intermediate plate in the posi-
tion indicated by the guide pin .
Place the top plate on the head
plate in the right position.
Gently tighten screws in diago-
nal order.
Screw in the three screws in
the centre of the pump top plate
until they are flush with the top
plate; then screw one final half
turn to tighten.
For orientation of disk springs
see fig. 2.
Carry out steps to for the
second pump head.
! Refit the pneumatic head connec-
tion:
Place tube onto the connecting
part of the angle fitting, turn angle
fitting to a straight position and
tighten the union nut.
f.) Final steps
Reconnect system tubing.
Reconnect the pump to the electri-
city supply.
If the pump does not reach the
desired vacuum after changing
diaphragms and valve plates/sea-
lings:
Check whether the spacers have
been replaced onto the diaphragm
screw thread.
Check the interconnecting pipe-
work connection between both
pump heads as well as the tubing
for leaks.
Possibly the screws on one of
the pump heads (or both heads)
are insufficiently tightened
(carefully tighten them again
crosswise).
If you have any questions about
servicing call our technical adviser
(see last page for contact tele-
phone number).
6. Troubleshooting
Sufficient vacuum is not reached
Possible reasons:
Tube connections are not tight
Condensate in the pump head
Switch the drying system on
or reduce the interval bet-
ween pump head ventilation
operations.
Diaphragms and/or valve plates/
sealings are worn out
Changing diaphragms and
valve plates/sealings: see
section 5.
If this problem occurs after chan-
ging of diaphragms or valve pla-
tes/sealings:
See information in section 5.
Pump is switched on, but does not
run, the on/off-switch on the pump
is not lit
Possible reasons:
Pump is not connected with the
power source.
No voltage in the power source.
Fuse in the pump is defective (only
authorized/qualified personnel
should investigate this problem):
Disconnect the pump from
the power source by pulling
out plug.
Placement of fuse:
The fuse is accessible after
opening the marked cover at
the bottom of the pump.
Dimension of the fuse:
see section 8.
Pump is switched on, but does not
run, the on/off-switch on the pump
is lit
Possible reason:
The thermal switch has opened
due to overheating
Disconnect the pump from
the power source, let the
pump cool down, investigate
the reason for the overhea-
ting and irradicate it.
