Safety
WARNING
Risk of burns from hot surfaces!
Pump housing and glandless motor can get hot and cause burns when touched.
• Only touch the electronic module during operation.
• Allow the pump to cool down before any work.
WARNING
Risk of scalding from hot fluids!
Hot fluids can cause scalding.
Before the installation or removal of the pump or the dismantling of the housing screws, ob-
serve the following:
• Allow the heating system to cool down completely.
• Close shut-off valves or drain the heating system.
DANGER
Danger of death from falling parts!
The pump itself and pump parts can have a very high net weight. Falling parts pose a risk of
cuts, crush injuries, bruises, or impacts which can be fatal.
• Always wear suitable protective equipment (e.g. helmet, gloves).
• Always use suitable lifting accessories and secure parts against falling.
• Never stand below a suspended load.
• During storage and transport, as well as before all installation and assembly work, ensure
that the pump is in a safe and secure position.

Preparing installation

Attach pipes to the floor, ceiling, or wall using appropriate fittings so that the pump does not bear the
weight of the piping.

Complete all welding and soldering work.
5.
Rinse the system.
6.
Provide shut-off devices before and after the pump.
7.
Comply with the inlet and outlet sections in front of and behind the pump.
8.
Ensure that the pump can be installed free of mechanical stresses.
9.
Allow a 0.33 ft distance around the electronic module so that it does not overheat.
