4. Initial start-up 1. Flush inlet line before connecting the
pump, to remove possible impurities from
pipes, hoses etc.
2. Connect pump inlet to inlet line and flush
the pump for 5 min. by using an internal
flushing valve, to remove possible impuri-
ties from pipes, hoses etc.

using an Allen key (only plugs with internal
hexagan sockets). Retighten the plug,
when water appears from the bleeding
plug.

the electric motor corresponds to the
direction of rotation of the pump (see label

5. Now the pump is ready for start-up.
WARNING!
Make sure that the direction of rotation of the
electric motor corresponds to the direction of
rotation of the pump (see label on pump).
Otherwise the pump will be damaged if a
check valve is placed between pump and feed
pump.
