➨
Position new diaphragm between diaphragm clamping
disc with square head screw and diaphragm support disc.
☞
Attention: Position diaphragm with white PTFE side to dia
-
phragm clamping disc (to pump chamber).
☞
Make sure that the square head screw of the diaphragm
clamping disc is correctly seated in the guide hole of the
diaphragm support disc.
➨
Use a face wrench with torque indicator to assemble dia-
phragm clamping disc, diaphragm and diaphragm support
disc with safety diaphragm clamping disc (use a open-
ended wrench to fix the components).
☞
Make sure that the square head screw of the diaphragm
clamping disc is correctly seated in the guide hole of the
diaphragm support disc.
Optimum torque for the diaphragm support disc: 6 Nm.
☞
The optimum torque is reached when the pointer in the
handle of the VACUUBRAND face wrench points to posi-
tion 2 which is the long line between the two shorter lines.
Do not tighten over 6 Nm!
☞
Ensure conductance of the connection.
➨
Position diaphragm clamping disc, diaphragm and dia
-
phragm support disc with safety diaphragm clamping disc
in the intermediate flange from the side which has a deep
-
ening as guidance for the diaphragm. Position safety dia
-
phragm and safety diaphragm support disc from the other
side.
☞
Attention: Position diaphragm with the light side towards
the pump chamber.
Ensure correct position of the diaphragm support disc (see
also exploded drawing). Assemble the side with the small-
er bearing surface towards the diaphragm.
position 2: indicator should point here when the optimal torque is reached
position 1: resting position

➨
Use the metal face wrench to disassemble diaphragm
clamping disc, diaphragm and diaphragm support disc
(use a open-ended wrench to fix the components).
Before reassembling ensure that all parts are clean, dry
and lint free, especially the valve seat. Remove residual
adhesive.
