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.

The power point must be located within
reach of its cable (length 3m). The
appliance must be positioned so that the
power point is accessible.

This way up

Typical Zip Hydrotap undersink assembly.

NOTE: All appliances must be placed on a

horizontal surface in an upright position, as

shown above.

Children should be supervised to ensure they do not play with the appliance

Refrigerant

The 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. 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. Once this mode is
completed the system reverts back to normal operation.

Lifting

Take care when lifting the HydroTap undersink unit. Some units may
exceed safe lifting limits. 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.

Airflow

The ambient temperatures this unit should operate within are 5ºC - 35ºC.
Proper air circulation must be provided. The system will operate satisfactorily

HydroTap Installation and Operating Instructions - 89944UK - August 2011 v1.04 Page 5 of 20

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.

Read These Warnings First (continued)

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.
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 A models requre a minimum cold and hot water supply pressure of 0.7 bar
(70kpa) and a maximum working pressure of 7 bar (700 kPa).

Filter Control

The 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 changesis are needed, follow the instructions on page 18 or contact your
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.

Included in the installation pack are adhesive

Altitude

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

All-thread rod

1. Make sure that the tap location will allow the nozzle to drain into the sink.

NOTE 1: The tap assembly must not be positioned more than 900mm

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

2. Cut a 50mm hole in the bench / sink top.

3. Ensure the silicon O-Ring remains in place as this is the moisture
seal against the bench / sink top. A light smearing of silicon sealant

on the O-Ring will ensure a watertight fit.

4. Pass all hoses through the 50mm hole and carefully locate the Head
Assembly on the bench / sink top.

5. From the underside of the bench / sink, mount the ‘base block’ by feeding
each of the tubes and electrical cable evenly in between the legs of the
‘base block’. Slide it up to meet the ‘all thread rod’, and pass the ‘all
thread rod’ through the centre of the ‘base block’.

6. Hold the ‘all thread’ steady and fit the 10mm ‘fixing 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 2: Under no circumstances should the Tap be twisted after the

installation is complete.

Step B - Installing the undersink unit

NOTE :

New hose sets supplied with the
unit should be used. Do not use
old hose sets.

SPECIAL NOTE: The HydroTap undersink units are heavy, take note of the
weights listed in the table on page 7. 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 tee piece (see Pages 14-15). Flush the hose prior to
connecting to the cold water inlet at the rear of the unit.

Position the HydroTap undersink unit as close as possible to directly beneath
