IMPORTANT
This appliance MUST NOT be connected via a
switchable or a solar (photovoltaic - PV) power
supply without manufacturer consultation.
The switching of the supplies will place the water
heater into a re-start cycle which reduces the
available heating time and may result in a lack
of hot water.
It is recommended this appliance is connected to
either a 24 hour continuous tari or an extended
o-peak power supply (minimum 16 hours per
day, noting that the minimum required running
time is governed by hot water demand and the
climate zone.
If this appliance is replacing an electric water
heater with a capacity of 250 litres (or greater),
then a connection to a 24 hour continuous tari
supply is recommended.
Disconnect all power prior to installation and commissioning.
This appliance is designed for single phase 240 Volts, AC
mains electrical operation.
