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 0845 6 005 005 or 0345 6 005 005.
What is the Zip HydroTap®G4 ?
This Zip HydroTap
®G4
is an electronically controlled, filtered, boiling and chilled water drinking system for
the industrial environment. 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 industrial applications. The
HydroTap®G4 utilises a conventional refrigerant compressor to chill the water and an immersion heating
element to boil the water. The boiling and chilled models will dispense boiling water (factory set to 98°C)
chilled water (factory set to 5-9°C). These units are NOT designed to be used as sanitary fixtures.
The Zip HydroTap
®G4
models which dispense boiling water (except those using the two button side touch tap)
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.
Legacy mode
The Industrial series of taps require the G4 Command-CentreTM to be set in legacy mode prior to initial
operation.(See section 5 for details).
Legacy mode is enabled / disabled in the service section of the main menu. Please note this is password
protected. Please call 0845 6 005 005 or 0345 6 005 005 for details.

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.
Refrigerant
The Zip HydroTap®G4 Command-CentreTM contains R134A refrigerant under pressure. Maintenance of the
refrigeration unit must be carried out by an accredited service provider or qualified refrigeration technician.
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 droplets may discharge through a vent outlet on the tap. If the tap
is not installed using the font, 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 2 'Ventilation', page 13, for correct installation to prevent overheating. The vent kit supplied must be
fitted.
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,
pages 23 - 25.

Before installation
Before installation ensure that the following have been
provided at the installation site
• Review of all the technical specifications.
• Ensure the under counter cupboard floor can support the product weight
when full of water (allow an extra 5-8kg when full).
• Sufficient space in the cupboard to install the Command-CentreTM and
other components in accordance with these installation instructions. See
technical specification, page 9 for dimensions. Make allowance for a
booster if required. See sections 3 to 4, pages 19 to 25 for installation
instructions.
• For Zip HydroTap®G4 models without booster, 1 x 220-240V AC 13A socket
will be required.
For Zip HydroTap®G4 models with booster, 2 x 220-240V AC 13A sockets will
be required.
(One socket is for the Command-CentreTM and the other for the booster).
• Both the Booster and Command-CentreTM must installed in accordance
with IEE regulations.
Note Check all cable and hose lengths against inlet /outlet positions before
proceeding (see sections 3 to 4, pages19 to 25 for general layout).
• A potable water supply connection with isolating valve inside the
cupboard within reach of the braided hoses and positioned so that the
connection point and the stop cock will not be obstructed when the
Command-CentreTM is installed.
• If an external filtration or water softening device is required, then it is
important to allow extra space for these items.
• A potable cold water supply with a minimum working pressure of:
(see page 9 min. / max. water supply pressure).
• If pressure is likely to exceed 0.7 MPa (7 bar), install a 0.35 MPa (3.5
bar) pressure limiting valve.
• The appliance must be placed with its base in a horizontal position.
IMPORTANT! Do not proceed with the installation if these requirements are
not met.

Industrial HydroTap®G4 - tap installation
Side touch (tapered base) taps
• Make sure the tap location will allow the nozzle to drain into
the sink. Note The top touch tap spout is 20mm shorter
than the side touch spout.
• For side touch taps, use the template supplied to correctly
locate the Ø35mm hole in the sink / worktop. After cutting
the Ø35mm hole, carefully align the template and drill the
3 x Ø6.5mm clearance holes, in the correct orientation
for either left or right hand operation. Refer to table of
recommended maximum and minimum thickness of
worktop, based on the length of the cap screws being used.
• A light smear of silicon sealant on the O-ring seal (side
touch), or on the black plastic spacer (top touch) will ensure
a watertight fit.
• Place the tap (and if applicable tapered base assembly)
into the Ø35mm hole so that all the seals are in place and
ensure the tubes and USB cable are not fouled.
Side touch taps (see diagram 1.1)
• Working from the underside of the bench, install the clamp
block (noting the position of the orientation marker). Feed
the three tubes and USB cable through each of their
respective holes. Slide the clamp block up and secure with
the M6 long series nut on the threaded rod.
• Fit the 3 x M6 cap screws and spring washers,through the
clamp block and bolt them into the tapered base. Check the
tap head position before securing it tightly against the work
top.
Top touch taps (see diagram 1.2)
• Install the stainless steel washer and spider, and secure
with the M6 nut as shown.
Note The tap assembly must not be positioned more than
900mm above the base of the Command-CentreTM. Failure to
do this may result in poor water delivery.
Note Under no circumstances should the top touch tap be
twisted after the installation is complete.
Note The M6 x 35 cap screws supplied with the side touch
tap are suitable for installation on worktops with a thickness
between 14 and 18mm. For worktops outside this range with a
thickness ‘T’, M6 cap screws with a length between 'T'+17 and
'T'+22mm should be used, as per the table below.
