6.0 COMMISSIONING
6.1 The electronic control system of the unit has a self commissioning and
calibration function. Once the heater is installed and all services have been
connected the appliance should require no further adjustment before use.
6.2 Check that all electrical, water and vent pipe connections have been made
and are secure.
6.3 Replace the cover and secure with the fixing screws. Ensure the tank discharge
tube is centrally located in the outlet spout. Turn on water then electrical
supply.
6.4 The READY indicator will flash to indicate the unit is in its "self commissioning"
mode. The water in the unit will not be hot enough to use at this stage (do
not draw water off).
6.5 The READY indicator will continue to flash until the unit has reached boiling
and has "self-calibrated". At this point the READY indicator will remain
illuminated. If for any reason the calibration procedure is interrupted it will
restart after a short delay but may result in the calibrated temperature being
too low. If this occurs switch the electrical supply OFF for several seconds
and then switch ON. The calibration sequence will reset. Wait for the READY
indicator to remain illuminated.
6.6 The unit is now ready to use, however, it is recommended that the first few
fills be drawn off and discarded to ensure the freshness of the water.
6.7 The tap sealing washer pressure has been already set. If the tap drips after
commissioning adjust the spring tension so that the handle is just loose.
a) Remove the tap bezel after removing the two screws securing it. Note:
to remove the bezel the handle will have to be operated. This will cause
water to discharge from the outlet (see Page 13 item 10).
b) Tighten the tap headwork nut (turn clockwise) until the handle is just
loose. Replace bezel and securing screws. Note: excessive adjustment will
dismantle the tap, if heated this would result in the uncontrollable release
of boiling water (see page 13 item 7).
6.8 Check for leaks.
6.9 IMPORTANT NOTE: each time the unit is switched off then switched on it will
always go through the same cycle (6.4-6.5) Water should never be drawn
off the unit until commissioning is complete and green neon light remains
constant.
