INSTALLATION
BOILING/CHILLED WATER TAP
Connect the silicone tube to the boiling water tap pipe, (the hot pipe is on the hot
lever side of the tap) then cut the silicone tube to length so that it slides onto the
boiling water outlet on the boiling water unit without kinking or creating low points.
Repeat the above step for the tap vent pipe to the boiling water unit vent.
Fit the quick connect fitting to the cold pipe. Connect the ¼" chilled water outlet pipe
to the ¼" quick connect fitting on the outlet line of the chiller, and cut so the chilled
water outlet tube inserts into the ¼"quick connect fitting on the Tap without kinking
(Ensure that the chilled water outlet pipe is able to also be connected to the
filtered outlet connector on the boiling water unit as this will facilitate flushing
the filter when a filter change is required).
Connect the tap communications cable to the tap/chiller comms plug from the boiling
water unit (8 Pin). If a Rheem chiller is fitted in the installation, the other comms cable
is to be plugged into the chiller comms plug (4 pin, connectors can only be inserted
one way onto the plugs).
WARNING: ENSURE THAT ALL TUBES ARE CUT TO LENGTH, INSTALLED
WITHOUT KINKS OR TIGHT BENDS, AND HAVE CONTINUOUS FALL. FAILURE
TO DO SO WILL CAUSE A DETRIMENTAL EFFECT ON THE PERFORMANCE
OF THE UNIT AND RENDER THE WARRANTY VOID.
Once the Tap is installed you can open the cold water isolation valve and turn
the unit on electrically.
AFTER POWERING THE UNIT UP FOR THE FIRST TIME
When the unit has been turned on for the first time, the battery pull tab located on the
timer must be removed by grasping firmly and pulling vertically up. This activates the
backup power for the timer to maintain your settings in the event of a power failure.
