5. Sound Emissions.
The RainsaverMK4E is virtually silent but may emit noises associated with the flow of water through
the unit.
In any case, the pump, which is connected to the RainsaverMK4E, may emit sound levels, which
may inconvenience you or your neighbours, or may operate during normal sleeping hours, which may
be prohibited by local government regulations. If this is the case, your RainsaverMK3 can be
switched off during the night or may be operated from a time clock. Your RainsaverMK4E will
automatically supply your house with Mains water supply while the pump is inactive.
6. Maintenance.
Ensure that water flowing through the Rainsaver MK4E is as free from dirt and foreign matter as
conditions allow.
Ease of accessibility will aid any maintenance and reduce any servicing costs if required.
Periodically inspect the rainwater tank inlet strainer and the first flush device. Periodically inspect
filters downstream and strainers if fitted upstream from the Bianco Rainsaver MK4E every 6 months
depending on water quality and usage.
Operate the Rainsaver on mains regularly or at least once a month by turning the power off to the
RainsaverMK4E.
