• Choose a suitable location to mount the tap, this may be an existing hole in your sink
or countertop.
• If a new hole is required check that the reach of the spout will be appropriate for your
sink before drilling the tap hole in the sink or worktop. The required hole diameter is
32 mm - ts in a standard sink.
• If installing in a Zen Font with Drain use the template supplied with the Zen Font to
establish tap hole position.
• The tap can be installed onto sink/countertop up to 50 mm thick.
• Place tap into hole, ensure the black o-ring is above the worktop. See Diagram 2.
• Place the steel washer onto the threaded section of the tap under worktop/ sink.
• Lastly the brass locking nut will screw onto the same threaded section. This will
secure the tap in position.
Step 1 - Prepare and Site the Tap

Step 2 - Prepare Manifold Connections
• It is imperative that no ttings, other than those specied in the instructions, are
installed within the ‘expansion zone’. This is everything beyond the check valve,
located within the manifold. See Diagram 3.
• Use Diagram 1 to establish suitable locations for each component which forms part
of the full installation. If you are installing a chiller, please see Diagram 4 in Section 2.
• Note the boiling tank must be located as close to the tap as practicable as it is not
possible to extend hoses provided.
• Attach ½”M BSP to 15 mm compression tting to otake 1, see Diagram 3, of the
manifold and tighten with spanner.
• Connect to desired length of copper pipe then connect to relief valve. This is a safety
device which must be tted and piped to drain via air gap before commissioning.
• From otake 3 of the manifold attach hose labelled‘manifold to exp vessel’using 1
black washer.

Step 3 - Mount Manifold and Connect Expansion Vessel
• Orientation of the manifold is optional, but the direction of ow must follow the
arrow on the manifold. The red handle is a service valve (boiling water isolation
lever) for future maintenance.
• Position the boiling tank vertically beneath the tap so that the exible hoses and
tap connector (black lead, 3.5 mm jack) can comfortably reach the tap and water
supply.
• Remove red caps from inlet and outlet connections at the back of the boiling tank.
• Choose desired location for manifold and mount using pipe clips (not supplied).
• Select a suitable location for the expansion vessel, consider the reach of hose
labelled ‘manifold to exp vessel’ as well as the need to keep the vessel itself in an
upright orientation (tting at the bottom).
• When correct distance is established mount the expansion vessel bracket to the
required surface using screw pack.
• Attach the other end of hose labelled ‘manifold to exp vessel’ to expansion vessel
using 1 black washer.
• Secure expansion vessel in place against bracket using metal band.
Step 4 - Connect Boiling Tank and Spa Tap
• From otake 2 of the manifold attach hose labelled‘manifold to tank’ using 1 large
white washer. Connect remaining end to tank inlet using 1 small white washer.
• Connect hose labelled ‘tank to tap’ to the tank outlet using 1 small white washer.
Connect other end to threaded boiling tap connection using 1 small white washer.
• Connect the black lead tap connector which is attached to the tap to the back of
the tank. This is a 3.5 mm jack which connects just above the tank inlet and outlet.
Step 5 - Connect Mains Cold and Scale Filter
• Isolate mains supply and make a connection using the 1/2” BSP to 15 mm brass
tting supplied. We recommend tting a service valve (not supplied) close by to aid
any future maintenance.
• Connect ½ “ female to 3/8 “ PF (push t) connector to the brass tting.
11

• Ensure all tubing is pushed fully into PF connectors and that locking collars
are used to prevent inadvertant removal.
• Use a suitable length of 3/8” tubing (cut using sharp knife, ensuring a clean straight
cut) to connect from mains supply to t-piece supplied.
• Select a suitable location for the scale lter housing ensuring easy access for future
maintenance. The arrow represents the water ow direction and must be followed.
• Depending on installation you may need to remove the lter head from bracket
and rotate 180° to ensure ow arrow is followed.
• To do so rst remove lter cartridge. Now grip bracket in one hand and the top
t-section with the other, turn 90° anti clockwise to release.
• Rotate 180° and reinsert t-section, turning 90° in whichever direction is required
depending on installation, to secure.
• Do not locate the lter above an electrical socket or other electrical device.
• Secure the bracket to the wall using the xings supplied. Replace the scale lter
cartridge.
• Use a suitable length of 3/8” tubing to connect from t-piece to scale lter head
inlet, ensuring water ow arrow is followed.
• Use a suitable length of 3/8” tubing to connect from scale lter head outlet, en-
suring water ow arrow is followed, to manifold inlet using ½“ female to 3/8 “ PF
connector.

Step 6 - Connect Cold Drinking Water Filter
• If you are installing a chiller proceed to section 2.
• Select a suitable location for the drinking water lter housing ensuring easy access
for future maintenance.
• Do not locate the lter above an electrical socket or other electrical device.
• Remove drinking water lter cartridge from the lter head, secure the bracket to
the wall using the xings supplied. Replace the lter cartridge into lter head.
• Use suitable length of ¼” tubing to connect remaining outlet of t-piece to drinking
water lter inlet marked‘IN’.
• Use suitable length of ¼” tubing to connect drinking water lter outlet marked
‘OUT’ to cold inlet of spa tap using ¼”x ¼” PF connector.
13

• Refer to Diagram 4 . The chiller should be installed after the t-piece and drinking
water lter, before the ltered drinking water tap connection.
• Two identical connectors are provided to connect the ¼” tubing to the‘WATER IN’
inlet on the chiller and then to connect a new run of ¼” tubing from the ‘WATER OUT’
outlet of the chiller to the tap.
• Ensure all tubing is pushed fully into PF connectors and that locking collars are used
to prevent inadvertant removal.
• Select a suitable location for the drinking water lter housing ensuring easy access
for future maintenance.
• Do not locate the lter above an electrical socket or other electrical device.
• Remove drinking water lter from housing and secure the bracket to the wall using
xings supplied. Replace the lter cartridge by pushing up into the housing and
turn towards the‘close’position.
• Use a suitable length of ¼” tubing to connect from remaining outlet of t-piece to
drinking water lter inlet marked ‘IN’.
• Use a suitable length of ¼” tubing to connect drinking water lter outlet marked
‘OUT’, one of the identical connectors and a black washer (provided with the chiller)
to facilitate connection to‘WATER IN’.
• Use remaining identical connector and a black washer (provided with the chiller) to
facilitate connection from‘WATER OUT’.
• Use a suitable length of ¼” tubing to connect chiller outlet marked ‘OUT’ to cold inlet
of Spa tap using ¼” x ¼” PF connector.
• It is recommended that the lowest setting (1) is used for drinking water. A higher
setting will cause the unit to work harder and in turn increase the temperature of
the installation environment.
Ensure you read separate chiller instructions for all important safety points and
instructions before installation.
Before commencing installation, ensure the location is a at level surface that will
allow for adequate airow around all sides of the appliance.

3. Commission and Check Water Connections
• Before plugging the tank into the power socket, the system must be full of water
and tested for leaks. Open all water valves to allow water to ow to the boiling
water tank.
• Pull the tap handle out to release the safety lock (see Section 5) and turn towards
the red marker to ll the tank, this will take approx 1 minute. When the tank is full,
water will ow from the spout.
• Check water ows smoothly from the tap to ensure all air has been purged from
the system (this could take up to 1 minute).
• Repeat the process for the cold water side turning the handle towards the blue
marker. Safety lock release is not required to dispense cold water.
• Test the pressure relief valve by twisting the red cap until water ows from the
valve.
• If it is discharging whilst the heater is turned o this is a sign that the incoming
pressure exceeds the 4.2 bar rating of the pressure relief valve. A pressure reducing
valve is required (not supplied).
• When the air is purged, the tap is closed and the system is fully pressurised, inspect
all connections for leaks.
• Flush each lter through ensuring the water runs clear.
• Ensure there are no obstructions in the expansion zone between the manifold and
the tank.
4. Electrical Connection
• Ensure that the installation area is dry.
• The boiling water tank is supplied with a pre-wired (1m) BS plug.
• Insert the plug into a suitable socket and turn the power socket on at the switch.
• The boiling tank will take up to 13 minutes to heat up from cold, depending on
incoming water temperature.
16

Smart Technology
• The boiling water tank has smart technology algorithms that learn and predict
usage: on when you need it, o when you don’t.
• The status ring on the base of the tap will light up red or green depending on the
temperature of the water in the tank.
• The red status ring indicates the water is heating. The green status ring indicates
the water is up to temperature and ready for use.
• When the heater is in a predicted non-use period (sleep mode) the status ring will
be green and fade on and o slowly. To exit this mode, open the boiling side of the
tap and allow water to ow until the status ring ashes green. The heater will then
return to boiling shortly after.
• If the status light begins ashing red this indicates a fault has been detected. The
unit should be isolated from the power supply and the water supply shut o before
contacting Hyco for further advice.
Status Ring Summary
Red Water is heating
Green Water is up to temperature - ready to use
Fading in/ out green Predicted non - use period (sleep mode)
Flashing red Fault detected
5. Operation
• This appliance can be used by children aged 12 plus and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they
have been given supervision or instruction concerning the use of the appliance in
a safe way.
• Check for signs of discharge from the pressure relief valve.
IMPORTANT
• Following the rst boiling cycle it is imperative to check all connections on the
boiling side and tighten all the exible hoses to and from the tank as these
can loosen on the rst boiling cycle.
