10.0 COMMISSIONING

10.1 The AQUATAP heater incorporates an electronic controls system which has a self-
commissioning and calibration function. No installer or user adjustment is necessary
before use.
10.2 Check that all electrical, water and vent pipe connections have been correctly made and
are secure.
10.3 To remove the main cover, unscrew the fascia securing screw and remove the fascia.
Remove the two top cover securing screws and four cover securing screws. The cover
can now be pulled back from the heater assembly. Caution should be taken here as the
two LED's are attached to the main cover. Pull the cover back to allow enough access to
the LED wires and slide the LED's from the slots in the cover to allow main cover
removal. Refit the cover in reverse sequence. When replacing the two LED wires
make sure the LED with the orange wire is at the top and the LED with the blue wire is at
the bottom.
10.4 If the cover has been removed, this should be replaced and secured with the supplied
fixing screws (see FIG. 11, page 17). Turn on the water and electrical supplies to the
AQUATAP heater.
10.5 Once commissioned, it is advisable to insulate both hot and cold hoses.
