Step B - Installing the undersink unit (all models)
SPECIAL NOTE: The HydroTap undersink units are heavy, take note of the
weights listed in the table on page 4. If you think you cannot lift the unit
safely, get help and avoid possible injury.
Before positioning the heater connect the braided water inlet hose (supplied) to the
cold water inlet on the unit. This is located at the rear of the unit.
Position the Zenith HydroTap undersink unit as close as possible to directly beneath
the Zenith 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.
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 for low usage installations.
Important Note: Proper air circulation must be provided for all Boiling and Chilled
models. The system will operate correctly only if the recommended air gaps are
achieved during installation. A ventilation hole measuring 100mm must be cut into
the top half of the cupboard door to accommodate the air vent provided. Make
sure that the undersink unit ventilation grilles are not obstructed in any way.
This instruction is critical!
Cupboard ventilation for Boiling only and Boiling Ambient models is recommended
but not essential.
