pump is cut off for over 5 minutes.
Do not remove the pump bonnet unless the water in
pump chamber is completely drained.
Rotate the fan with a screwdriver to check if the pump rotates
flexibly before startup. Remove the filling plug and prime the
pump chamber fully with clean water, then tighten the filling
plug.

Keep the valve narrow opened during startup. When the pump
runs normally, adjust the valve to the required flow.
When not using the pump and the ambient temperature is
below 4, empty the pump completely for frost and freeze
protection. The priming procedure must be repeated to restart
the pump.
Attention! If the appliance or the supply cord is
damaged, it must be repaired by manufacturer, its
service agent or qualified person.
