Read These Warnings First
Safety
This appliance is not intended for use by persons (including children) with
reduced physical sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety. Children should
be supervised to ensure that they do not play with the appliance.
The power point must be located within
reach of its cable. The power lead is
supplied with the plug head removed to
facilitate ease of fitting to a 13 amp fused
spur. The appliance must be positioned so
that the power point is accessible.
This way up
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 the 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 45 - 90 secs. Once this mode
is completed the system reverts back to normal operation.
Lifting
Take care when lifting the Zip HydroTap undersink unit. Some units may
exceed safe lifting guidelines. If you feel this is beyond your personal
capabilities, please seek assistance with the lift. The weights of the units are
marked on the packaging and given in the table under the heading “Installation
Requirements”. Do not lift the unit by the doors.
Typical Zip Hydrotap undersink assembly.
NOTE: All appliances must be placed on a
horizontal surface in an upright position, as
shown above.
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. 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.
Altitude (DOMBC3 AND DOMBA1 only.)
The Zip HydroTap is equipped with a self-calibrating program which caters for
altitude adjustment.

Read These Warnings continued
Filter Control (DOMBC3 and DOMBA1 only.)
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 15 or contact
your Zip Service Provider.
Frost Protection
If this appliance is located where the ambient air temperature could fall below
5ºC when the heater is not in use, do not turn off the appliance electrically.
This safeguard does not offer the same protection to the connecting pipework
and fittings.
Installation Environment Considerations
This unit is intended for indoor use only and should never be installed outdoors
or exposed to the elements of nature. This unit must not be positioned in an
area that may be cleaned by a water jet. This unit must not be cleaned by a
water jet.
Warning:
Zip HydroTaps are designed to operate within 1ºC to 2ºC of set point for boiling
water and at 5°C to 15°C for chilled drinking water. For the Domestic Compact
model only, the chilled water set point can be adjusted in 2ºC increments as
follows: 5-9º ; 7-11º ; 9-13º or 11-15ºC.
All boiling water units are self calibrating to 98ºC, which is the recommended
setting. Adjustments to the 98ºC setting are not recommended however, under
certain circumstances adjustments may be made between 68º - 100ºC . The
100ºC setting is not recommended as units may discharge or boil over, more
frequently.
Adjustments to the set points can only be made within the Service Menu. For
details see Step F on page 11.
Caution must be observed when changing any settings within the
Service Menu as any changes may affect the normal operation of the unit.
Note:
Always ensure the silicone 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.

Step A - Installing the tap
1. Make sure that the tap location will allow the nozzle to drain into the sink.
2. Install the 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.
NOTE 1: The tap assembly must not be positioned more than 900mm
above the base of 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.

Step B - Installing the undersink unit
SPECIAL NOTE: The HydroTap undersink units are heavy, take note of the
weights listed in the table on page 6. If you think you cannot lift the unit
safely, get help and avoid possible injury.
Before positioning the heater connect the water inlet hose (supplied) to the
cold water inlet on the unit. This is located at the top of the DOMBC3 and
DOMBA1, and at the top rear of the DOMHB1.
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
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.
Note: Ventilation Buffers
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

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.

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. * Ensure the plastic spacer is
correctly located under the Font as 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.
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

Internal Filter Replacement
The Zip HydroTap notifies when filter replacement is due. The default setting
is 6000 Litres, but this can be set in increments of 1000Ltr from 1000Ltr to
10000Litres. When a filter change is due, the Change Filter light will flash
white once a minute and remain so until reset. A filter status light is located
between the Red and Blue Lights on the tap head assembly.
Depending on local water quality conditions and usage, the filter may require
changing anywhere from 1000 Litres to 10000 Litres. You may also need to
replace the filter if you notice unpleasant odours or tastes.
Some water may drip from the filter head (socket) during replacement. Keep a
bucket and towel handy to catch drips and mop up any spills.
To change the Filter:
1. Scroll through the screen menu to “Filter Flush Off” this isolates the water
supply.
2. On the compact model, remove the front cover by unscrewing the two
Phillips headed screws and lift off to expose the filter. Unravel the Blue
filter flush line and place the open end in the bucket.
3. Relieve system pressure via the filter flush stop cock, a quick open and
close will do. Use the bucket to catch the discharge.
4. Grasp filter cartridge and twist right to left one quarter turn until it stops.
