General product features
CS Command-CentreTM
Thank you for purchasing a Zip HydroTap®G4 Celsius. Please read and follow these instructions carefully to
ensure safe and trouble free service. If service is required, please call 0845 6 005 005 or 0345 6 005 005
What is the Zip HydroTap®G4 Celsius?
The Zip HydroTap®G4 Celsius is an electronically controlled drinking water system for the home, all systems
dispense mixed hot and cold water, and different options can be purchased to dispense filtered boiling,
filtered chilled and filtered chilled and sparkling water as standard.
The Command-CentreTM is an under counter drinking water appliance with a Celsius tap mounted on the
sink or worktop, which has been designed for residential applications. These utilise a conventional refrigerant
compressor to chill the water (for chilled models) and an immersion heating element to boil the water (for
boiling models). Chilled sparkling models utilise a CO2gas cylinder to carbonate the chilled water. Boiling
water systems will dispense boiling water (factory set to 98°C). Chilled water systems will dispense chilled
water (factory set to 6 - 10°C) and chilled and sparkling water (factory set to 3-5°C) all models also dispense
mixed hot and cold water.
The boiling water models are fitted with a tap mounted safety lock. In addition, there are various energy
saving options accessible via the main menu. Each boiling model is equipped with a self-calibrating program
which caters for altitude adjustment. The water filter and CO2cylinder are disposable items which will require
periodic replacement and are covered by a limited OEM warranty.
It is important that the installation be done safely, correctly and completely, in order to utilise all the benefits
that the HydroTap®G4 can provide.
Usage
The Zip HydroTap®G4 Celsius is intended for use in residential kitchens and not for commercial use.

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 model must be installed in accordance with water supply
byelaws, current IEE regulations and relevant local authority bylaws.
Safety
This HydroTap®G4 is not intended for use by children under 8 years old or 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 HydroTap®G4 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 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 trades-person. 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 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 which 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 connections at the top
rear of the Command-CentreTM. Refer to the table on page 9 ‘Technical specification’ for the weight of the
Command-CentreTM.
Airflow
The ambient temperatures this unit should operate within are 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’ for correct installation to prevent overheating. The door buffers 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 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 electrical power. This safeguard does not offer the same protection to the connecting
pipework and fittings.
Positioning
It is important to ensure that the Command-CentreTM is positioned in an accessible area close to the floor
level. It’s base must be mounted in a horizontal position with all inlets and outlets facing up. The tap must be
located above the Command-CentreTM see section 5 ‘Command-CentreTM installation’ for details.
Note As with all refrigeration products the Command-CentreTM must not be turned on its side during
transport, installation or use.

4.3 Connect the gas hose
Connect the threaded end of the braided gas hose to the regulator, then connect to the John Guest fitting on
the top of the Command-CentreTM via the connection marked ‘CO2IN’
To turn the gas on, rotate the black knob on top of the cylinder clockwise. Then adjust the outlet pressure, by
rotating the regulator knob clockwise to between 2.7- 3.0 bar (green zone).
Note The arrow should sit in the green zone of the regulator gauge; it should not fall in the red or yellow
zones.
4.4 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 velcro strap. Ensure the cylinder is in an upright position.
Note Care must be taken when working with high pressure CO2, and in no cases should the normal
operating pressure of between 2.7- 3.0 bar be exceeded.
