Heatrae Sadia Aquatap Installation & User's Instructions page 18

10.7 The "READY" indicators will continue to flash until the heater unit is full and has self -
calibrated to the correct boiling temperature. At this point, the "READY" indicators will
stop flashing and remain illuminated. If the calibration procedure is interrupted, it
will restart after a short delay but may result in the calibration temperature being too low.
Should this occur, the electrical supply should be switched off for several seconds. When
switched on again, the calibration sequence will re-commence and the "READY"
indicators will again flash. Wait until the ready indicators remain illuminated before use.
Do not draw any water off during the self - commissioning mode.
10.8 The AQUATAP heater unit and dispenser tap should now be flushed to remove any
installation residues and pasteurise the surfaces in contact with the water.
10.9 To dispense hot water press the button marked "SAFETY" on the dispenser tap
followed by the HOT water button (red). The hot water dispensing button must remain
pressed for the water to flow. If released, it will be necessary to press
the "SAFETY" button again before more water can be dispensed. To dispense
chilled/ambient water, press the CHILLED/AMBIENT button (blue). The safety button
does not have to be pressed for chilled/ambient water. If both the CHILLED/
AMBIENT and HOT water buttons are
depressed simultaneously the CHILLED/
AMBIENT button will always take preference.
10.10 Following flushing, it is recommended that the
power is switched off and the AQUATAP casing
removed to check for any internal leaks.
Always disconnect the electrical supply
before removing the cover.
If there are no leaks evident, replace and secure
the front casing. Switch on the electrical supply.
The "READY" indicator will illuminate on the AQUATAP unit and
dispenser tap. The "READY" indicators will flash for a short time as the unit re-calibrates
and checks the correct fill level. When the "READY" indicators stop flashing and remains
on, the AQUATAP unit will be ready for use.
10.11 Following commissioning, the following should be explained to the user:
• Correct operation of the AQUATAP water heater and dispensing tap.
• Advise the position of the water and electrical isolation points.
• How to identify if there is a malfunction of the unit. Explain that in the event of a
malfunction of the unit or dispenser tap, any maintenance or servicing must only
be carried out by a competent installer.
• Explain the necessity for regular maintenance of the system to ensure continued
safe and efficient operation.
• Draw the users attention to Section 11.0, page 19 of these instructions which
detail the correct use of the system.
