Mounting cover
Attention!
Equipment may leak if the gasket is
damaged.
It is therefore essential that you
always insert a new gasket before re-
attaching the cover.
Make sure that the cover is not tilted
or skewed when refitted.
Fix cover to equipment body.
Fasten screws / nuts and bolts with the
following tightening torque:
DN15 to DN25: 35 Nm
DN40: 45 Nm
Purging pipes
Attention!
Equipment may be damaged by unsuitable
cleaning fluid.
Rinse the pipe with the same fluid that
is used during normal operation.
Make sure that the cleaning fluid does
not come into contact with the fluid
used during normal operation.
Make sure that the cleaning fluid does
not damage the equipment material if
you use a different fluid for cleaning
than the normal operating fluid.
Switch on the installation and rinse the pipes.
Check connections for leaks.
After rinsing keep the installation switched on
until the pipes are completely empty.
Switch the installation off and protect it against
unauthorised or unintended re-activation.
