Mounting the pump head
Assemble the intermediate plate (
4
), connecting plate (
3
) and head plate
(
2
)
Push the assembled components onto the pump housing with finger
pressure
Secure the pump head to the housing using the 4 head screws (
1
)
Re-adjust overflow using Allen wrench and open-ended spanner. (Use
pressure gauge, see also Chapter 7.3)
The maximum tightening torque for the head screws is 1 Nm.
Head screws that have been undone before should be carefully
screwed in by hand so that the screws engage in the existing
threads.
WARNING
It must be ensured that the overflow pressure can be
accurately set again after dismantling!
Too much pressure can cause leaks or make the
system rupture!
Not enough pressure can adversely affect the
operation of your system.
8.5. Replacing diaphragm, valves and seals
The components of the pump head are available as spare parts (Chapter 10
Spare parts and accessories)
Avoid damage to the diaphragm surface when replacing the diaphragm.
Ensure that the support and the spacers beneath the diaphragm are correctly
arranged and all present.
Tighten the diaphragm finger-tight.
