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 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 commercial 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 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. Each tap 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 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 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 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 Zip HydroTap®G4. The Command-CentreTM may exceed safe lifting limits. If
you feel this is beyond your personal capabilities, please seek assistance with the lift. The weight 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 19, 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 1, Tap installation, pages 11 - 18.

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 4-5kg 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 5, pages 20 to 31 for installation
instructions.
• For Zip HydroTap®G4 BC,AN, AV and BCH 100/75 models, 1 x 220-240V
AC, 13A fused spur will be required.
For Zip HydroTap®G4 BC,AN, AV and BCH 140/75 models, 2 x 220-240V AC,
13A fused spurs will be required.
(One spur is for the Zip HydroTap®G4 and the other for the booster).
• Fused spurs should provide all pole disconnection with a contact
separation of at least 3mm, installed in accordance with IEE regulations.
Note check all cable and hose lengths against inlet /outlet positions before
proceeding (see sections 3 to 4, pages 20 to 28 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.
• For the AN100(140)/75G4 All-in-One 'Mains', an external hot and cold
water supply will be required.
• 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.

Section 2
Ventilation
Ventilation for all models
• The clearance envelope dimensions stated in the specification sheets and installation instructions must
be observed.
• Adequate ventilation must be provided to ensure that the cupboard space temperature does not exceed
350C.
Preferred arrangement
• The vent kit supplied with the Command-CentreTM should be used to provide adequate ventilation by
convection in normal usage.
NoteThe vent kit has to be installed in a way that allows air to be drawn in from the bottom of the cupboard
and expelled through the top of the cupboard. The outlet vent Ashould be towards the top of the door (position
A1) or side of the cupboard (position A2). (Where possible
air inlet vent and the air outlet vent should be positioned at
opposite ends of the same cupboard space).

Alternative arrangement
In situations where the preferred arrangement does not
provide adequate ventilation by natural convection a Dual
exhaust fan kit* (SP93156) must be fitted to the cupboard
door or side (as shown in the illustration below) and
connected to the Command-CentreTM DIN socket.
* For dual exhaust fan cut-out dimensions see the instructions
provided with the kit.

3.1 Product description
The booster system is a compact electronically
controlled auxiliary water heater. It is intended to
provide pre-heating of water before it enters the Zip
HydroTap®G4 boiling tank. The booster is supplied
as standard with BC140/75G4, BCH140/75G4
AN140/75G4 and AV140/75G4 models. However,
it may be later installed, as an accessory for
BC100/75G4, BCH100/75G4 AN100/75G4 and
AV100/75G4 models, to increase their boiling water
output.
Note 1 Water connection
blue cap - water in
red cap - water out.
The braided hoses cannot be
lengthened.
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.
