7.0 COMMISSIONING
7.1 Check that all electrical, water, and vent pipe connections have been
made and are secure.
7.2 Turn on the water supply and then switch on the electrical supply.
Ensure that the On/Off switch is in the On position. (Located at the
rear).
7.3 The Wait/Ready light will flash yellow (indicating below temperature)
and the unit will slowly fill with water (1.2 L/Min). When water passes
the low level sensor (just below tap level) the element will also be
energised. When the normal operating water level is reached the
solenoid will be disabled and the element will continue to heat the
unit until the full operating temperature has been reached. At this
point the Wait/Ready light will show solid orange indicating that the
unit is full and up to temperature.
7.4 Check for leaks.
Subsequent Use
7.5 After the unit has finished the commissioning cycle, and water is
drawn from the tap, water will be replaced in short cycles (small
amount of water and then heat). The solenoid and element will never
be on at the same time unless the unit is switched off and on again
(re-setting commission mode). In normal use the unit will always be
at operating temperature indicated by the Wait/Ready light showing
a solid (not flashing) colour. When the unit is full and ready, the light
will be orange and when the unit is only part full the light will be
yellow.
