Electronic instantaneous water heaters
Description
• Can provide a constant supply of hot water to
one or more outlets.
The heating element switches on automatically
when the minimum flow rate is exceeded and
switches off when flow rate reduces below the
minimum.
• Regulates power consumption electronically
depending on supply water temperature and
flow rate to achieve the required outlet
temperature.
• Also regulates power consumption based on
outlet temperature to ensure precise
temperature control irrespective of fluctuations
in voltage and water pressure.
• Power rating can be selected at the time of
installation.
• Bare wire heating system ensures fast
response for immediate, energy efficient
delivery of hot water.
• The required outlet temperature can be set via
two touch sensitive membrane keys within the
range 30°C to 55°C with digital display of the
selected temperature.
• Enables selection of two pre-programmed
temperature settings.
• Provides visible indication when the heating
power available is unable to achieve the
required temperature at the selected flow rate.
• Maximum inlet temperature of 70°C is suitable
for use with pre-heated water from solar
heating systems.
• Optional wireless control (ZL016) for
convenience and concealed installations.

The hot water pipes must be thermally
insulated.
Maintenance
Contact Zip HydroCare on 0845 6 005 005.
Minimum flow rate 2.0 litres/min.
Warranty
One-year on site parts and labour.
For full details of the Zip Warranty Scheme visit:

A minimum water pressure of 2 bar is
recommended for optimum performance.
Maximum flow rate will be achieved at a water
pressure of 6 bar.
Typical Installation
Should be installed by a suitably qualified
installer of electric instantaneous water heaters.
The appliance complies with protection class
IP25 for over-sink installation, protection class
IP24 for under-sink installation and may be
installed in zone 1.
Electrical
The appliance must be earthed and connected
to the supply by means of permanent wiring
through an isolation switch having a contact
separation of at least 3mm on all poles and
protected by a suitably rated circuit breaker.
In order to minimise thermal losses, the distance
between the appliance and the outlet fitting
should be as short as possible. Recommended
maximum distance 2 metres.
The cross sectional area of the connection cable
must be in accordance with the power rating of
the appliance and the specific requirements of
the installation site.
CEX-U enables installation under-sink, close to
the outlet fitting, keeping thermal losses to a
minimum.
The appliance must be installed in accordance
with current IEE regulations.
Mains supply
Plumbing
The appliance is intended for connection to a
potable mains water supply. The specific water
resistance of the supply must not fall below the
minimum specified on the rating plate.
Hot and cold connecting pipes should be
WRAS approved and of copper or steel
construction. Plastic pipes may only be used if
conforming to DIN 16893 Series 2.
IP Rating
CEX-O IP25 / CEX-U IP24.
Suitable for installation in Zone 1.
Approvals
• WRAS approved
• VDE approved to the LVD and EMC directives
• CE endorsed
N.B. Instantaneous water heating is the most
energy efficient way of directly heating water
electrically, however, the delivered water
temperature will be dependant upon the
incoming water temperature, supply voltage
and selected flow rate.
