7. System preparation
7.1. Start up of new system
In order to ensure a problem-free start up of a new
system the pipe system and pump must be flushed
and bled.
Bleeding the pipe system
1. Turn on the water supply to rinse and bleed the
entire system. If satellites are installed open the
tap furthest away until no air or dirt comes out.
Then rinse and bleed the next tap and continue
until the tap closest to you has been rinsed and
bled.
Bleeding the pump
1. Loosen the relief plug (A) (drawing 0627131)
1-2 revolutions until water and air begin to flow out.
Never loosen the relief plug while the pump
is running as this may damage the packing.
Tighten the relief plug again.
2. Start the pump so that all remaining air pockets
are forced up to the top of the pump.
3. Stop the pump
4. Loosen the relief plug 1-2 revolutions again and
bleed the system until only water flows out.
5. Tighten the relief plug once more.

into the water pipe - which means
that the system has to be bled
again.
