and the capabilities to do so.
This water heater is not intended to be operated by persons with reduced physical, sensory or mental
capabilities i.e. the infirm, or by children. Children should be supervised to ensure they do not interfere
with the water heater.
This water heater uses 240 V AC power for the electrically operated components. The removal of the front
cover(s) will expose 240 V wiring. It must only be removed by a qualified person.
For continued safety of this water heater it must be installed, operated and maintained in accordance with
the Owner’s Guide and Installation Instructions.
TEMPERATURE SENSORS, TEMPERATURE ADJUSTMENT, THERMOSTATS
The temperature sensors control the maximum water temperature in conjunction with the control system.
Water is heated to either 60°C or 75°C depending on the mode of operation. These temperature settings are
fixed and cannot be adjusted.
Power is only used when heating is required. There is no need to switch the water heater off when it is not in
use, except when you are on an extended holiday.
The thermostats act as a backup safety device to control the electricity supply to the heating unit. Each
thermostat and its protective over temperature cut out is mounted inside the front covers of the water heater.
PRECAUTIONS
Where damage to property can occur in the event of the water heater leaking, the water heater must be
installed in a safe tray. Construction, installation and draining of a safe tray must comply with AS/NZS 3500.4
and all local codes and regulatory authority requirements.
The water heater must be maintained in accordance with the Owner’s Guide and Installation Instructions. Refer
to
on page 14 and to
“Anode Inspection and Replacement”
on page 17.
If this water heater is to be used where an uninterrupted hot water supply is necessary for your application or
business you should ensure that you have back-up redundancy within the hot water system design. This should
ensure the continuity of hot water supply in the event that this water heater were to become inoperable for any
reason. We recommend you seek advice from your plumber or specifier about your needs and building back-
up redundancy into your hot water supply system.

If you plan to be away from home for only a few nights, we suggest you leave the water heater switched on.
If it is necessary to turn off the water heater:
Switch off the electrical supply at the isolating switch to the water heater.
Close the cold water isolation valve at the inlet to the water heater.
TO TURN ON THE WATER HEATER
Open the cold water isolation valve fully on the cold water line to the water heater.
Switch on the electrical supply at the isolating switch to the water heater.
When the power is turned on, the water heater will enter the Initialisation mode.
The green, yellow and red LEDs will flash in an undefined sequence for up to sixty (60) seconds,
which will include different types of flashes and may include short periods where the LEDs remain
all on or all off.
The blue LED will extra fast flash.
The water heater will then enter either Maintenance mode if the water in the top of the tank is below
60°C or Standby mode or Variable Heating mode if the water in the top of the tank is above 60°C.
