Circulation pump for heating and solar
Warning
The pumped liquid can be very hot and under high
pressure. Therefore, drain the system or close the
isolating valves on either side of the pump before you
remove the screws.
After modifying the orientation of the pump motor, the
pump must only be started once the system has been
refilled with liquid or the isolating valves on either side
of the pump are open.
Limit the heat loss from the pump housing and pipe-
work. You can reduce the heat loss from the pump and
pipework by insulating the pump housing and the pipes
by means of insulating shells.
Do not insulate the pump motor or cover the control
panel.
Highly efficient. Simple. Good!
