MAINTENANCE
It is recommended to periodically check and clean the non-return valves and to keep the SCALA2 pump
clean, including keeping the ventilation holes free of dust.
The pump has a debris filter to protect the pump. The filter is placed on the bottom and can easily be
removed and cleaned with a stiff brush. Clean the debris filter once a year or as needed.
To remove the inlet or outlet non-return valve, follow the steps below:
1. Turn off the power supply and disconnect the power plug.
2. Shut off the water source.
3. Open a tap to release the pressure in the pipe system.
4. Close the isolating valves and/or drain the pipes.
5. Gradually open and remove the priming plug.
6. Remove the drain plug and drain the pump.
7. Unscrew the union nut holding the inlet connection. Depending on
the installation type, it may be necessary to remove the pipes from
both the inlet and outlet connections.
8. Pull out the inlet connection.
9. Pull out the inlet and outlet non-return valve.
10. Clean the non-return valve with warm water and a soft brush.
11. Assemble the components in reverse order.
TAKING PUMP OUT OF OPERATION
If the pump is taken out of operation for a period of time, for
example during the winter, it must be disconnected from the power
supply and placed in a dry location. Proceed as follows:
1. Stop the pump by means of the on/off button.
2. Disconnect the power supply.
3. Open a tap to release the pressure in the pipe system.
4. Close the isolating valves and/or drain the pipes.
5. Gradually loosen the priming plug to release the pressure in the
pump.
6. Remove the drain plug to drain the pump.
7. It is recommend to store the pump indoors in a dry location. Due
to humidity, the disconnected pump must not be left outside for a
longer period of time.
START-UP AFTER A LONG TIME OF INACTIVITY
If the pump has been drained, it must be filled with liquid before
start-up. See section 3 for start-up instructions.
