Thank you for purchasing a Zip HydroTap. Please read and follow these instructions carefully to ensure safe
and trouble free service. If service is required, please contact your Zip Service Provider.
What is the Zip HydroTap ?
The Zip HydroTaps are electronically controlled, filtered, Boiling, Chilled and Sparkling water, drinking
systems for kitchens and tea rooms. The HydroTap units are under bench drinking water appliances with a
dispensing tap mounted on a sink or bench, which may be used for residential or commercial applications.
These units utilise a conventional refrigerant compressor to chill the water and (for BCS) an immersion
heating element to boil the water and all utilise a CO2gas cylinder to carbonate the chilled water. Depending
on the model, these units will dispense boiling water (factory set to 98°C) chilled water (factory set to 3-5°C)
These units are NOT designed to be used for sanitary fixtures.
The boiling water units are fitted with a tap mounted, child safety lock. In addition, there are various energy
saving options accessible via the main menu. Each boiling unit is equipped with a self-calibrating program
which caters for altitude adjustment. The 2.64kg CO2bottle is refillable and should be returned to your
nearest HydroTap agency for exchange, whereas the water filter is a disposable item. Both 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
the HydroTap can provide. Each unit can be ordered with the Tap Head Assembly for Disabled use. The
disabled levers are supplied with Braille caps for the visually impaired.

If the air flow, using the silicon door buffers, is insufficient, it will be necessary to fit a standard HydroTap vent
kit, which ensures heat dissipation through natural convection via installed vents.
For high use applications, where the cupboard space temperature is near 35°C, or higher, the inlet vent
(See Item B below) and silicon buffers, need to be fitted. If the airflow is still insufficient to maintain normal
operating temperatures then the inlet vent and door outlet vent (See item D below) will need to be fitted.
Alternatively a fan kit may be installed, using the AUX din plug of the right hand side of the appliance
(Contact your local service centre for availability).
Note: The 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. Therefore placement of the outlet vent should be towards the
top of the door or on the side of the cupboard.

STORAGE WARNING:
A CO2gas cylinder of 2.640kg must be installed in an open plan area or in an enclosed room, with a volume
no less than 50m3. If more than 1 gas cylinder containing CO2is present within the same location, the
recommended ventilated area should be in proportion to the number of gas cylinders stored in that location.
A ventilated area is a non-enclosed area which could include the kitchen, living room etc.
See gas bottle and MSDS sheet for a complete list of warnings (see: www.zipwater.com).
4.1 Secure the cylinder cradle
After marking out the cradle location, secure it to a suitable wall, within 1 metre of the unit. Make sure the gas
bottle, regulator and cradle assembly can comfortably fit, with sufficient clearances, before securing the cradle
inside the cupboard. Due to regulatory requirements the gas bottle must be stored securely and in an upright
position. Secure the bottle with the hook-and-loop straps provided.
4.2 Connect the regulator:
After removing all packing material, fit the regulator to the gas bottle as shown in the diagrams. Ensure the
plastic seal is fitted securely inside the large chrome nut, before attaching to the gas bottle. If the plastic seal
is not an easy fit over the spigot, soak it in hot water, before re-applying. Do not force the seal to fit.
Turn the regulator OFF by rotating the regulator knob, all the way out, in an anti-clockwise direction.
NOTE: Two plastic seals are supplied with a new regulator. Only one is required, the other is supplied as
a spare part.
4.3 Connect the gas hose:
Connect the braided gas hose to the top of the Command Centre via the John Guest fitting marked ‘Gas IN’
Then connect the threaded end to the regulator (Do not lose the small sealing olive). When commissioning,
first, turn the regulator, grey knob, all the way out (anticlockwise). Then turn the gas ON by rotating the black
knob on top of the cylinder, anti-clockwise. Finally, adjust the outlet pressure by rotating the grey regulator
knob in a clockwise direction, 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
sections.
4.4 Test for gas leaks:
When commissioning, use soapy water to 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.
Fit the gas bottle into the cradle and secure with the Hook-and-loop strap. Ensure the bottle is in an upright
position.
NOTE: Care must be taken when working with high pressure carbon dioxide, and in no cases should the
normal operating pressure of between 2.7- 3.0 bar be exceeded.

2. Remove any swarf or unwanted material.
3. Push the tube into the John Guest fitting making
sure all connections to the John Guest fittings are
pushed in past the “O”ring to full depth, at least
15-16 mm.
4. Check for a good joint by pulling back on the tube.
If the tube comes out of the fitting, repeat the
above step.
5. To remove the tube, press the collet into the fitting
and at the same time pull back on the tube.
1. Fit the carbonation valve to the white tube, as close
as possible to the Y-connector from the tap.
2. Use the white tube to connect the carbonation valve
to the sparkling outlet connection on top of the Com-
mand Centre.
3. The carbonation valve has an adjustable ow rate.
The optimum setting for the valve is between 1.2 -
1.6 litres per minute. Using a 6mm Allen key or a
large at blade screw driver, you can adjust the ow
on the valve. See Section 7.7 for carbonation valve
ow rate adjustment.
Warning - Take care NOT to use excessive
force during adjustment of the valve.
