⚠
WARNING
:
You must not skip this section, we are not liable for any safety or performance issues as a result of
not following the step by step installation guide with due care, DO NOT TURN ON THE BOILER UNTIL FULLY FLUSHED.
1. Switch on mains power to the boiler but leave the display screen off (in standby mode / flashing
2. Place the Hotkey on the front of the tap, water will now begin to purge air from the entire system.
During the purging of air in the system it is normal for the tap to spit, continue until the stream from the
centre channel of the tap aerator is continuous. Depending on the incoming water pressure it will take apx. 4-5
minutes to fill the tank and purge the air.
⚠
After the air is purged from the system (this takes around 3 minutes) you must continue to run cold water
through the tank and tap for a further minimum of a 5 minutes to flush it fully.
During the flushing period check all connections made during the installation carefully for leaks.
3. After the flushing period is completed remove the Hotkey to stop the 98°C water.
4. Press and hold the
error "E" codes.
5. Press the
key on the boiler screen and set the target temperature to 98°C, the boiler will take approximately
"+"
9 minutes to reach its "READY" state. Use this time to complete the checklist items in this guide.
The few first times the boiler fills and heats from a "fully cold" state it is normal that the tap may drip
slightly from the spout centre channel during heating, this will self adjust with use.
6. After the boiler reaches its "READY" state repeat steps 1-2.
7. With all tap handles in the closed position again check the installation carefully again for any leaks.
Please complete the commissioning checklist, if any questions are answered as no or below the stated acceptable threshold then
you must rectify this before concluding:
