WARNING
Pressurised system
Death or serious personal injury
‐
Design the system for the maximum
pump pressure plus 10 % to avoid pipe
burst.
We recommend that you install a pressure
relief valve designed for the maximum
pump pressure.
Minimum torque for fitting the first riser
pipe section to the pump is 55 Nm.
1. Fit the riser pipe to the pump. Grip the pump by
the outlet chamber. Take care not to damage the
cables.
a. If you use plastic pipes, use a compression
coupling between the pump and the first pipe
section.
Plastic pipes expand when they are
loaded. Consider this fact in relation
to the installation depth.
