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?
The Zip HydroTap®G4 is an electronically controlled, filtered, chilled and sparkling water, drinking system
for kitchens and tea rooms. The Zip HydroTap®G4 Command-CentreTM is an under counter drinking water
appliance with a dispensing tap mounted on a sink or worktop, which has been designed for commercial
applications. The Zip HydroTap®G4 Command-CentreTM utilises a conventional refrigerant compressor to
chill the water and utilises a CO2gas cylinder to carbonate the chilled water. The Command-CentreTM will
dispense chilled and sparkling water (factory set to 3-5°C). The HydroTap®G4 is NOT designed to be used for
sanitary fixtures.
There are various energy saving options accessible via the main menu. The water filter and CO2cylinder
are disposable items which will require periodic replacement and are covered by a limited OEM (original
equipment manufacturer) 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. Classic models can be ordered with the tap head assembly for
disabled use. The disabled levers are supplied with Braille caps for the visually impaired.

A vent grille, supplied should be used as an inlet vent and fitted to the cabinet side (adjacent to the
Command-Centre air inlet) as shown below. It must take in air from the room or another ventilated space.
This space could be an adjacent cupboard, (via a communicating port) on condition that it does not contain

Section 2
CO2Cylinder
STORAGE WARNING
WARNING! The cylinder ( containing 1kg of CO2) should be installed in a well ventilated area
of area no less than 38m3.
If more than 1 gas cylinder containing 1kg of CO2is present within the same location, the recommended
ventilation area should be in proportion to the number of gas cylinders stored in that location.
A ventilated area in a non-enclosed area which could include the kitchen, living room etc.
See gas cylinder and MSDS sheet for complete list of warnings.
2.1 Secure the cylinder
Secure the gas cylinder supplied to a suitable wall, within 1 metre of the Command-CentreTM, in an upright
position. This is undertaken by screwing the metal bar holding the hook-and-loop strap to a cupboard wall,
200mm above the floor or base of the cupboard. Make sure the gas cylinder can stand in place before
securing to the wall. Due to regulatory requirements the gas cylinder must be stored securely and in an
upright position.
2.2 Connect the regulator
Remove the gas cylinder from the strap. Make sure the regulator
knob is turned fully clockwise to the end-stop before fitting.
Screw the regulator (clockwise) onto the cylinder. Be aware that
some CO2may be discharged from the connection between the
cylinder and the regulator when assembled together. Any CO2
released will be cold. Screw on the regulator to stop this leakage.
Note The leaking CO2will be cold.
2.3 Connect the gas hose
Connect the threaded end of the braided gas hose to the
regulator. Then connect the push fit fitting to the top of the
Command-CentreTM via connection marked ‘CO2IN’.
To turn the gas on, rotate the regulator knob anti - clockwise to
the end stop.
2.4 Test for gas leaks
Using soapy water perform a leak test. Apply the soapy water
to the gas connections using a sponge or brush. If any bubbles
appear and grow, there is a gas leak at the connection. Clean away the soapy residue and tighten or refit the
leaking connection. Make sure the gas is turned off when tightening or refitting the leaking connection.
Refit the gas cylinder to the hook-and-loop strap. Ensure the cylinder is in an upright position.
Turn the knob fully
clockwise before fitting

Closed
Open

Page 14 of 20 804050UK G4 Commercial chilled and sparkling installation instructions - Sept. 2016 - v3.02
After replacing a cylinder or after making a
gas connection, perform a leak test to check for
gas leaks between regulator and cylinder, and between regulator
and braided hose.
Stage 1
1. Turn the gas off.
2. Using soapy water applied with a sponge, or with a
brush, cover all of the gas joints with a liberal
amount of suds.
Stage 2
1. Turn the gas on.
2. Inspect the joints for leaks.
3. If any bubbles appear to grow, the joint will need to be
resealed and tested again.

Warranty
Certain warranties may be implied by law into your contract with Zip. The warranty provided below is
additional to these implied warranties and nothing set out below shall limit your statutory rights or rights at law.
Zip Heaters (UK) warrants that, should the hot tank (boiling models only) fail within five years of installation
subject to satisfactory maintenance and registration of the product, or any part fail within two years of
installation, the part will be repaired or replaced free of charge by Zip, its distributor or service provider, (except
as set out below), provided the appliance is installed and used strictly in accordance with the instructions
supplied, and that failure is not due to accident, misuse, abuse, unsuitable water conditions, or to any
alteration, modification or repair by any party not expressly nominated by Zip.
No costs are payable by the customer other than any mileage or travelling-time charges incurred by a Zip
service provider or the cost of removal, cartage and re-installation of any component of the appliance if it
needs to be returned for repair to Zip or its distributor.
This warranty does not cover damage resulting from non-operation of the appliance, the use of non authorised
parts or consequential damage to any other goods, furnishings or property.
No warranty applies to the life of any filtration cartridge installed with the appliance as cartridge life may vary
according to water quality and the rate of water consumption.
Zip does not exclude, restrict or modify any liability that cannot be excluded, restricted or modified or which
cannot, except to a limited extent, be excluded, restricted or modified as between the owner or user and Zip
under the laws applicable.
Furthermore this warranty does not displace any statutory warranty, but, to the extent to which Zip is entitled
to do so, the liability of Zip under any statutory warranty will be limited at Zip’s option to the replacement of the
appliance or supply of equivalent appliance, the payment of the cost of replacing the appliance or acquiring an
equivalent appliance, or the payment of the cost of having the appliance repaired or the repair of the
appliance.
HydroTap®G4 residential models are designed specifically for use in a domestic environment and
inappropriate installations such as in a commercial location will invalidate the warranty.
