Product Specifications
All specifications, stated operational flow rates and output water temperatures are valid within the range of
water conductivity:
• 80µS/cm to 800µS/cm + 15% at 20°C (µS–microSiemens)
• 1.25k
Ω
-cm to 12.5k
Ω
-cm +15% at 20°C
NOTE: Water conductivity may be less than 80µS/cm. Reduce flow rate to achieve comfortable water temperature.
Water conductivity greater than 800µS/cm + 15% will generate an error condition. In this circumstance, the
appliance will shut down safely and without damage.
Reference
Preparation for Use
After installation, this two step procedure must be followed.
The unit must be primed – this is required only once – nominally at installation.
(Priming is
only required when the electricity supply to the unit has been turned off/removed from the unit – for
example, after a power failure or an isolation switch OFF condition).
Priming is required to set the unit up environmentally to ensure that the heating ramp-up time from start during
normal operation will be as short as possible, without incurring power overshoot.
Once primed, the unit will ramp-up to the optimised power required at the time without overshoot.
Note: Power overshoot typically results from the maximum power input required to get a heat exchanger up to
working temperature as quickly as possible.
However, as the unit does not incorporate a heat exchanger,
this initial power ‘kick’ is not required at start up.
STEP 1: Flush
• Flushing is required to clear the unit of plumbing debris that may have collected in the piping during
installation. Remove the Inlet Filter (13) whilst doing this and replace after flushing.
• This is done with the electric power supply turned off.
• Flushing should be allowed to continue for 1 to 2 minutes.
STEP 2: Prime
• Turn the electricity supply on – check for the LED (16) slow flashing
gREEN
. The unit is now in stand-by mode.
• Turn on the hot water faucet to a flow rate greater than 1.5ltr/min (the unit will start heating – check for LED
(16) fast flashing
gREEN
), and allow the unit to run for about 3 minutes.
The unit is now primed and ready for use.
