Installation & Operating Instructions
Birko DownUnder Under-Sink Boiling Water
Page 3
Electrical
This appliance is equipped with 1.8 metre power cord and plug to connect to a 10 amp
220-240 volt power outlet. For fixed wiring use a licensed electrician.
Note: this appliance is electronically controlled and will not operate with a portable generator
power supply or a split system transformer.
Drainage
A vent hose is located inside the under-sink unit to allow for the discharge of any excess water
and steam in the unlikely event of a system failure.
The vent hose is intended to drain into the base of the unit whilst maintaining an air break so
as to eliminate the risk of cross contamination of the water should the base become filled.
Water held in the base of the unit may then flow into the safety tray. To avoid the risk of
damage to cupboards and flooring, the safety tray must be drained as per AS/NZS3500.4.
Commissioning
When the installation is complete, turn on the water and check for leaks.
To avoid damage to the system, water must be turned on before power.
When the power is turned on the system will automatically prime as below.
Priming Mode
When the power is turned on for the first time, the system will prime itself automatically,
covering heating the element. The element will switch ON and boil that amount of water. This
will take 10 to 15 minutes and will start the heat-and-refill process until the boiling chamber is
filled. The system then goes into standby mode, keeping the stored water close to boiling point.
Operation
To dispense boiling water press and hold down the round button on the tap base.
After a two second delay boiling water will flow from the spout for 20 seconds or until the
button is released.
If more water is needed, press the round button again.
If, after much use, the system fails to respond, it should be left to replenish itself.
If continuous operation is required for 30 minutes or more a rest period of 60 seconds every
ten minutes will be necessary.
If the taste of the water deteriorates, it may be time to replace the water filter.
Always ensure that water AND POWER are turned off before replacing filter.
For safety’s sake, filters should be replaced at least once each 12 months.
Safety
Take care when using the system otherwise scalding may occur.
The system is fitted with a manual-reset safety device for boil-dry protection.
The system is also fitted with an auto-reset thermostat to detect excessive steam in the event
of any failure of the electronic controls or water solenoid valve.
If either safety feature is actuated, the heater must be serviced by a Birko Service Provider or a
suitably qualified technician. It is not user-serviceable.
If for any reason the water supply must be turned off, it is most important that the power be
turned off to prevent any damage to the system.
