Safety

Do not allow young children, handica pped or infirm persons, to use the Zenith
HydroTap without supervision.

Refrigerant

The Zenith HydroTap Chilling unit contains 134A refrigerant under pressure. No
part of the unit should be exposed to a naked flame. Maintenance of the
refrigeration unit must be carried out by an accredited service provider or
qualified refrigeration mechanic.

Qualifications

If any power cord or plug is damaged it must be repaired only by a qualified
technician.To avoid hazards,all installation procedures must be carried out by
a suitably qualified tradesperson.The power cord and general power outlet
must be in a safe visible position for connection.

Venting

Sometimes steam and / or boiling water may discharge through a vent outlet at
the mouth of the tap. If the ta p is not installed using the Font pedestal, ensure
the tap body is located so the tap outlet safely drains into the sink bowl area.

NOTE: On startup, the controls take the system through a calibration process
which causes the unit to over-boil for a period of 90 secs.This is normal
operation, once this mode is completed the system reverts back to normal
operation.

Zip Hydrotap undersink assembly.

The appliance must be placed in a

horizontal position, as shown above.

Lifting

Take care when lifting the Zenith HydroTap undersink unit.Some units may exceed
safe lifting limits. Do not lift without assistance. The weights of the units are
given in the table under the heading “Installation Requirements”.Do not lift the
unit by the doors.

Airflow

The ambient temperatures this unit should operate within are 5ºC - 35ºC. Proper
air circulation must be provided.The system will operate satisfactorily only if
the recommended air gaps are provided, these are 65mm min rear clearance
and 50mm side clearance.An air vent is provided with each unit for high usage
applications, this must be installed in the top half of the cupboard door as a
matter of course.An optional fan kit is available and should be used to ensure
adequate ventilation. Make sure that the ventilation grilles of the undersink unit
are not obstructed.

Altitude (not HT boiling only series)

The Zenith HydroTap is equipped with a self-calibrating program which caters for
altitude adjustment.

Filter For models : BC, BD, BF

The Zenith HydroTap filter control is preset to 6000 Litres to provide trouble-free
flow and operation in most installations. Local water quality conditions may
require an alteration to this capacity.In areas where the water has a high
concentration of sediment, the preset litre ca pacity may be shortened to avoid
poor flow,taste or odour situations. In areas where the water quality is above
average, lengthening the preset capacity may be desirable, but not essential. If
any of these changes is needed, follo w the instructions on page 11 or contact
your Zenith Service Provider.

Installation Requirements continued

• This switch must provide all-pole disconnection and a contact separation
of at least 3mm installed in accordance with wiring rules.

• Cold water supply with a minimum working pressure of 175 kPa and a
maximum working pressure of 700 kPa connected via an isolation valve.If
pressure is likely to exceed 700 kPa,install a 500 kPa Pressure Limiting
Valve.

• The fitting of an air flow vent cut into the top half of the cupboard door
concealing the HydroTap requiring a cut size of approximately 100mm
circular, to provide adequate warm air displacement. In installations where
high volume draw-off will occur,the fitting of the accessory exhaust fan is
essential.

Important: Do not proceed with the installation if these requirements are
not met.

Special tools required

In addition to normal tools, the following will be required:

• 38mm diameter sheet metal hole punch for sink tops.(not supplied)

• 38mm diameter hole saw for timber bench tops.(not supplied)

• Nut runner tube spanner (supplied) for fixing tap assembly.

Note: A stainless steel washer is

When installing a Font unit:

• 108mm diameter sheet metal or hole saw to suit surface being cut.

Installation procedure

Step A - Installing the tap (all models)

1. Make sure that the ta p location will allo w the nozzle to drain into the sink.

2. Install the 38mm hole in the bench / sink top.

3. Remove the “Spider Clamp” and S/S washer by undoing the 6mm nut
located on the “All Thread” at the base of the Tap Head Assembly.
A tube spanner is supplied in your installation kit for this job.

4. Ensure the black plastic spacer remains in place as this is the moisture
seal against the bench / sink top.A light smearing of silicon sealant on the
underside of the spacer will ensure a watertight fit.

5. Pass all three hoses through the 38mm hole and carefully locate the Head
Assembly and black spacer on the bench / sink area.

6. From the underside of the bench / sink area re-locate the S/S washer and
“Spider Clamp” by feeding each of the three tubes and electrical cable
evenly in between the legs of the “Spider Clamp”. Slide it up to meet the
“All Thread”,and pass the “All Thread”through the center of the “Spider
Clamp”.

7. Hold the “All Thread”steady and re-fit the 6mm nut to the “All Thread”
using the tube spanner supplied in the kit. Check the Tap Head position
before securing it tightly against the bench / sink top.

NOTE 1: The tap assembly must not be positioned more than 1m above

the HydroTap unit. Failure to do this may result in poor water delivery.

NOTE 2: Under no circumstances should the Tap be twisted after the

installation is complete.

Installation procedure continued

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.

Step C - Connecting the tap
