Step B - Installing the undersink unit (all models)
Before positioning heater connect the braided water inlet hose (supplied) to
cold water inlet on unit. This is located on the left hand side.
Position the Zip HydroTap undersink unit as closely as possible to directly
beneath the Zip HydroTap tap head.
The connection tubes supplied with the tap head assembly CANNOT be
lengthened.
Leave at least a 50 mm air-gap without obstruction on each side of the
unit.
Fasten the fixing brackets (located behind the access door) to the cupboard
floor using screws provided.
Adjust both cupboard door hinges and attach the supplied rubber door
buffers to the doors to create a 4 mm air-gap between the doors and the
cupboard. This is the minimum ventilation requirement.
Caution:
Proper air circulation must be provided. The system will operate
correctly only if the recommended air gaps are achieved during installation.
If this is not possible, ventilation slots must be cut into the top AND bottom
of the cupboard door. Make sure that ventilation grilles are not obstructed.
Allow access to water inlet located on the left hand side of undersink unit.
Step C - Connecting the tap
Model ABC
Mount the External Chilled Water Expansion Chamber (ECWEC) into the cold
water outlet on the top of the undersink unit by pressing down firmly into
the John Guest fitting.
Measure and trim the blue tube and connect it to the top centre outlet of
the ECWEC.
Measure and trim the small tube and connect it to the offset outlet on the
top of the ECWEC.
Measure and trim the red marked tube and connect it to the hot water
outlet on the top of the undersink unit.
Measure and trim the unmarked tube and connect it to the vent outlet on
the top of the undersink unit
Connect the tap electrical connector to the cord attached to the undersink
unit. Align the pins carefully and do not force the plug. Clamp the cable to
the wall with clip provided so that the plug hangs vertically.
Note:
When trimming any silicon tubes trim to minimum length, do not
loop the excess or allow kink of the tubes. When connecting, slide
the tube over the pipe at least 25 mm.
