7.0 COMMISSIONING

7.1 The electronic control system of the Supreme has a self

commissioning and calibration function.  Once the heater is
installed and all services have been connected the unit should
require no further adjustment before use.

7.2 Check that all electrical, water and vent pipe connections have

been made and are secure.

7.3 Replace the cover and secure with the fixing screws.  Ensure the

tank discharge tube is centrally located in the outlet spout.  Turn
on water and electrical supply.

7.4 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.

7.5 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.

7.6 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.

7.7 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.
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.

7.8 Check for leaks.
