COMMISSIONING
To Turn On and Fill the Boiling Water Unit
• Turn on the water supply and then the electrical supply at the isolating switch to the
boiling water unit.
• The unit should begin filling (check for external leaks)
• Set the timer. Refer to “Setting the Timer” on page 7
IMPORTANT:
On initial start up, this boiling water unit automatically runs through a set-up cycle
to detect the boiling point of water. During this cycle steam may discharge from the
vent pipe for a short time. This set-up cycle will take up to 18-30 minutes depending
on unit, and when completed (boiling point detected) the unit will commence
incremental filling. It is important NOT to operate the tap during the set-up cycle
because it may affect the operating temperature of the unit. Explain to the
householder or responsible officer the functions and operation of the boiling water
unit. Upon completion of the installation and commissioning of the boiling water unit,
leave this guide with the responsible officer.
The factory setting for the unit is programmed to automatically operate 24 hours a
day, 7 days a week. It is highly recommended for the user to program the timer, as
this will increase the life of the unit, and consume less power (see page 7 for Setting
the Timer). The electronic controller constantly monitors and controls the water level
and water temperature to optimise the boiling water delivery.
Operation based on an inlet water temperature of 18ºC
