Thank you for purchasing a Zip HydroTap®G4. Please read and follow these instructions carefully to ensure
safe and trouble free operation. If help and advice is required, please call 0345 6 005 005.
What is the Zip HydroTap®G4 ?
This Zip HydroTap
®G4
is an electronically controlled, filtered, boiling and ambient water drinking system for
the kitchen. The HydroTap®G4 systems are under counter drinking water appliances with a dispensing tap
mounted on a sink or worktop, which has been designed for residential applications. The HydroTap®G4
utilises an immersion heating element to boil the water. The boiling models will dispense boiling water (factory
set to 98°C). These units are NOT designed to be used as sanitary fixtures.
The Zip HydroTap
®G4
models which dispense boiling water are fitted with a tap mounted safety lock. In
addition, there are various energy saving options accessible via the main menu. The system is equipped with
a self-calibrating program which caters for altitude adjustment. The water filter is a disposable item which will
require periodic replacement and is covered by a limited OEM warranty.
It is important that the installation be undertaken safely, correctly and completely in order to utilise all the
benefits that the HydroTap
®G4
can provide. HydroTap
®G4
Classic taps can be ordered with the tap head
assembly for disabled use. The disabled levers are supplied with Braille caps for the visually impaired.

Important safety instructions
This manual contains important safety and installation instructions for the Zip HydroTap®G4.
Please read all warnings, installation requirements and installation instructions before installing any Zip
HydroTap®G4. This system must be installed in accordance with water supply byelaws,
current IEE regulations and relevant local authority byelaws.
Safety
This appliance is not intended for use by children under 8 years or persons (including
children under 8 years) with reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given supervision or instruction concerning the 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. Cleaning and user maintenance shall not be made by children without supervision.
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 on the tap. If the tap is not
installed using the font pedestal, ensure the tap body is located so the tap outlet safely dispenses into the
sink bowl area.
Lifting
Take care when lifting. The Command-CentreTM may exceed safe lifting limits. If you feel this is beyond your
personal capabilities, please seek assistance with the lift. The weights of the Command-CentreTM is marked
on the packaging. Do not lift the Command-CentreTM by the front cover or any of its connections. Refer to the
technical specification, see page 9, for the weight of the product.
Airflow
The Zip HydroTap®G4 operates within the ambient temperature range 5ºC - 35ºC. Proper air circulation
must be provided. The system will operate satisfactorily only if the recommended air gaps are provided. See
Section 1 'Ventilation', page 11, for correct installation to prevent overheating.
Altitude
Water boils at varying temperatures at different altitudes. The HydroTap®G4 adjusts for this during startup
calibration and will recalibrate itself on a regular basis.
Frost protection
If the HydroTap®G4 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.o
Positioning
It is important to ensure the Command-CentreTM is positioned in an accessible area close to the floor level.
The Command-CentreTM must have it’s base mounted in a horizontal position with all inlets and outlets facing
up. The tap must be located above the Command-CentreTM. See Section 4, Command-CentreTM installation.

•
Before proceeding, read the installation and user instructions
•
Check all the components are present and correct.
•
Check that you have all the necessary tools
• Ensure the underbench can support the product weight when full of water,
(Check the specifications in the main book and allow an extra 5-8kg when full. )
Before installing ensure the following have been provided at
the installation site:
•
Sufficient space in the cupboard to install all of the undersink units in accordance
with these Installation Instructions. Refer to technical specification for dimensions. If
required, make allowance for a booster heater. (Refer to the main book, for detailed

•
A potable water supply connection with isolating valve inside the cupboard within
reach of the flexible braided hose and positioned so that the connection point and the
stop cock will not be obstructed when all the undersink units are installed.
•
For Zip HydroTap 160/125 &160/175 models, a 220-240Vac, 10A GPO will be
required. For Zip HydroTap 240/175 models, two 220-240Vac, 10A GPOs will be
required. (One GPO is for the Zip HydroTap and the other for the Booster heater).
NOTE: Check the cable lengths and outlet positions before proceeding.
•
A potable cold water supply with a minimum working pressure of 172kPa and a
maximum working pressure of 700kPa connected via an isolation valve.
•
For the mains pressure All-IN-ONE, both a hot and cold water supply will be required.
•
The undersink appliances must be mounted in upright positions as shown in the
diagrams.
IMPORTANT! Do not proceed with the installation if these
requirements are not met.
STEP 1- Prepare and fit the Taps
Hole positioning: Position the tap such that it dispenses into
the sink bowl with ample clearance for a cup or tea pot. Alternatively,
the tap could be mounted away from the sink using a Zip Font, avail-
able as an accessory.
Apply a light smearing of silicon sealant
on the underside of the upper spacer to
ensure a watertight fi t.

Note 2 The electrical cable
length is 0.6m.
Note 3 Position the booster
within reach of the fixed hose
lengths, keeping the booster
as close as possible to the
Command-CentreTM inlet /
outlet connections.
Note 4 Ensure the booster
is mounted in an
upright position (as shown)
with a horizontal base.

2.4 Braided hose connection s
• The cold water inlet (blue cap) and hot water outlet (red cap) are marked on the rating plate. Connect
the braided hoses from the ‘BYPASS OUT’ fitting on the Command-CentreTM to the water inlet of
the booster (blue cap) and from the outlet of the booster (red cap) to the ‘BYPASS IN’ fitting on the
Command-CentreTM. Avoid exerting mechanical force on the booster. This can be achieved by using a
spanner on the flats of the inlet and outlet connections when tightening the braided hose connectors.
Do not over-tighten ! Tighten the braided hoses by hand, then turn a further 90O to 180Owith a spanner.
• Once the water connections have been made, check for any leaks and rectify as necessary.
