Product Description

Hydrotap BH, 3-in-1 and BCH, 4-in-1 models employ the use of selected Hydrotap B and BC assemblies, which have
been factory modified to accept a secondary mixer tap. The mixer tap is connected so that it draws water directly from
the cold water mains as well as from the boiling water storage tank. In this way the combination of the two taps will
allow the user to select water at 4 different temperature ranges. (see estimates below)

For BCH, 4-in-1 models, the main Hydrotap outlet will deliver Boiling and Chilled water and the secondary mixer tap
outlet will deliver Hot and Cold water. Whereas the BH, 3-in-1 models will perform exactly the same, except there is no
chilled water option.

The estimated temperature ranges will be:

Boiling water: 68°C - 98°C

Mixed water: From ambient up to 20°C above ambient

Cold water: Ambient. (Approx. 15°C - 20°C)

Chilled water: 5°C - 10°C

NOTE:

Read all instructions and precautions before
proceeding. This unit must be installed in
accordance with water supply byelaws,
current IEC regulations and relevant local
authority byelaws.

Read These Warnings First

Safety

Do not allow young children, handicapped or infirm persons, to use the Zip
HydroTap without supervision. Children should be supervised to ensure that
they do not play with the appliance.

Refrigerant

The Zip 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 cable 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 cable and 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 tap 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.

Note:

Always ensure the tubes are
shortened so that any excess is
removed and their route is the
most direct line between the tap
assembly and the HydroTap unit.

Do not allow the tubes to sag or
droop so water is trapped within
the hoses. Always maintain a
constant fall

Positioning of the tap assembly
must be within the following
parameters:

The height between the base of
the Hydrotap unit and the base
of the Tap assembly cannot be
greater than 900mm.

Lifting

Take care when lifting the Zip 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 accessory exhaust 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.

Included in the installation

pack are adhesive backed silicon buffers. If air vents are not installed in the
cupboards housing the HydroTap, the buffers must be placed on the inside
edge of the cupboard door to create a slight gap ensuring a minimum airflow.
Failure to do this may cause the HydroTap to overheat and operate inefficiently.

Minimum Pressure warning:

All BH and BCH models require a minimum cold water supply pressure of 2 bar
dynamic and a maximum of 7 bar.

Filter Control

The Zip 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 capacity 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, follow the instructions on page 11 or contact
your Zip Service Provider.

2. Cut a 35mm hole in the bench / sink top.

3. 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.

4. Pass all three hoses through the 35mm hole and carefully locate the Head
Assembly and black spacer on the bench / sink area.

5. From the underside of the bench / sink area install 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 centre of the “Spider
Clamp”.

6. Hold the “All Thread” steady and 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.

(see P19 options)
The approved vented tapware, as supplied must be used. It is advisable to

fit the tap to the sink before installing the undersink unit. Do not dismantle
the assembled tap body during installation. Mixer taps are factory tested and
sealed to provide optimum performance.

Before connection, it is recommended to flush water supply pipes thoroughly
to remove any silt or fines.

1. Make sure the tap location will allow the nozzle to drain into the sink. (P19)

2. Cut a 35mm hole in the bench / sink top.

3. Screw the 2 Braided hoses to the underside of the mixer tap, ensure that

each are firmly attached and in the correct colour or marking sequence.
See the diagram below for correct orientation.

4. Fasten the mixer tap body to the sink using the bolt & plate system

provided.

5. After the tap has been secured in place, screw the 1/2” tube (15) into the

remaining position on the underside of the mixer tap. (see diagram P18).

6. Connect the braided hose with a WHITE band to the incoming cold water

the check valve (11) and connection pipe (15) (see diagram P18).

8. Connect the braided hose with a BLUE band to the elbow (24) on the lower

end of the venturi (1) (see diagram P18).

Step C - Installing the undersink unit

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)
from the cold water tee piece (see item 23 on P18) to the cold water inlet at
the rear of the unit.

Position the Zip HydroTap undersink unit as close 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
and 65mm at the rear

The following instruction is CRITICAL:

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.

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.

Cupboard ventilation for Boiling only models is recommended.

Font installation procedure

1. Position the Font template (provided) on the bench area. Ensure the
position you select is within the length of the supply tube and USB cable
fixed to the Tap Head Assembly. These cannot be extended.

2. Check again for correct positioning. The supply hoses must have constant
fall back to the tank assembly. Cut the holes as shown on the template.

3. Once holes are cut, locate the Font base in position, from the underside,
lightly tighten the securing rod with the nut and washer provided.

4. Apply a light smear of silicon sealant to the underside of the black base
ring, this will provide a water tight seal against the Font base when
clamped. * Ensure the plastic spacer is correctly located under the Font.

5. Now take the Tap Head Assembly. Feed the hoses and USB cable through
the Font base, then through the plastic spacer that sits under the font
base but on the bench top. This stops warping of the base plate. Ensure
the Tap spout is directly centred over the Font drain. Fit the “Spider
Clamp”, nut and washer onto the “All Thread”. Have all the supply tubes
and USB cable located evenly between the “Spider Clamp” legs. When
satisfied with the positioning, tighten the fixing nut with the Tube Spanner
provided in the kit.

6. Tighten the securing pin so the Font base is flush with the bench top.

NOTE: The fixing nut above the drain elbow can be loosened to correctly

position the direction of the elbow. Ensure when the re-positioning is
complete the nut is re-tightened to ensure a water tight seal.

7. Connect a drain hose (22mm ID) from the Font base outlet elbow to the
closest drain trap spigot available. If a spigot is not available use the snap
on spigot and worm drive clamps supplied in the kit. (Instructions and
diagrams are supplied in the kit ref:81496).

8. Ensure the positioning of the snap-on spigot is on the “sink” side of the
trap and not the “waste” side. Once positioned, a hole (13mm ID) will
need to be drilled to provide waste access to the drain line. The snap-on
unit will require suitable sealant to keep it water tight against the waste
pipe. Finish by fitting the worm drive clamps tightly on either side of the
spigot and fitting worm drive clamps to either end of the drain hose. The
drain hose from the Font must have constant fall

9. Connect the Tap head Assembly supply hoses and vent as per the

to remove heat from the cupboard space. This fan should be purchased and
connected to the HydroTap if the airfow characteristics of the cupboard space
are inadequate for the effective removal of hot air, thereby adversely affecting
the operation of the HydroTap.

The fan can be installed so that it extracts air from, or forces air into the
cupboard space, whichever is the most effective for your installation.

Application of the fan is of paramount importance in situations where the

Electrical
