3. Safety instructions
Installation, initial operation and maintenance of this appliance must only be conducted by an authorised professional, who will then be
responsible for adherence to applicable standards and installation regulations. We assume no liability for any damages caused by failure
to observe these instructions.
• Do not use the appliance until it has been correctly installed and unless it is in perfect working order.
• The appliance is suitable but not limited to domestic use and similar applications inside closed, frost-free rooms, and must only be
used to heat potable water from mains supply.
• The appliance must never be exposed to frost.
• The appliance must be earthed at all times.
• The minimal specific water resistance must not fall below the value stated on the label.
• The maximum water pressure must not exceed the value on the label.
• Before commissioning for the first time and each time the appliance is emptied (e.g. due to work on the plumbing system, if there is a
risk of freezing or in case of maintenance), the appliance must be vented correctly in accordance with the instructions in this manual.
• Do not remove the front cover under any circumstances before switching off the mains electrical supply to the unit.
• Never make technical modifications, either to the appliance itself or the electrical leads and water pipes.
• Pay attention to the fact that water temperatures in excess of approx. 43 °C are perceived as hot, especially by children, and may
cause a feeling of burning. Please note that the fittings and taps may be very hot when the appliance has been in use for some time.
• Water inlet temperature must not exceed 70 °C.
• In case of malfunction, disconnect the fuses immediately. In case of leaks, cut off the cold water supply instantly. Repairs must only be
carried out by the customer service department or an authorised professional.
• This appliance must not be used by any person (including children) with limited physical, sensorial or mental abilities or failing experience and/or knowledge unless they are supervised by a person responsible for their safety or received instructions about how to use
the appliance. Children should be supervised in order to make sure that they do not play with the appliance.

7. Description of applicance
The instantaneous water heater DSX is a microprocessor-controlled, pressure-resistant water heater for a decentralised water supply to
one or more tap connections.
Its electronic control regulates the power consumption depending on the selected outlet temperature, the respective inlet temperature
and the flow rate, thus reaching the set temperature exactly to the degree and keeping it constant in case of pressure fluctuations. The
required outlet temperature can be entered between 20 °C and 60 °C and is indicated on the digital display.
This appliance may be able to be used with a Thermostatic Mixing valve or where serving a fixture that does not require temperature limitation such as a commercial Kitchen sink or Cleaners sink. Refer to AS/NZS 3500.4.
8. Operation
As soon as you open the hot water tap, the instantaneous water
heater switches on auto ma ti cally. When the tap is closed, the appliance automatically switches off.
Temperature setting
The required hot water temperature can be increased or decreased
in increments of 1°C by briefl y pressing the up arrow and down
arrow function keys.
Depressing the function key for a longer time changes the temperature continuously.
The temperature can be adjusted between 20°C and 60°C.
Note. Reducing the temperature below 20°C displays ‘- -’ and the
heating function will not operate.
Note:
If temperature is set below 20 °C with arrow key
the display
shows “--“ and the appliance switches off the heating function.

• Press and hold the setup key
, the display now counts backwards
from “10” to “00” in second intervals.
• The appliance is reset at value “00”
Note:
To cancel the reset process, release the setup key
before the count-
down reaches “00”.
Energy saving
Set the required hot water temperature on the appliance.
If the water is too hot reduce the temperature on the appliance instead of
mixing with cold water.

Reset completed
Adding cold water wastes valuable energy that has been used producing
excessively hot water.
Also, any cold water added is not controlled by the electronic circuitry
meaning that precise temperature control can no longer be guaranteed
when supplying more than one outlet.
Power limit
If the maximum power available from the appliance is insuffi cient to heat
the volume of hot water being drawn off to the required temperature, the
control valve automatically reduces the fl ow rate so that the set temperature is reached.
Operating with solar systems
When operating with solar systems, the appliance should be used with
a thermostatic mixing vavle or a tempering valve to ensure that the inlet
temperature does not exceed 70 °C.
If the inlet temperature exceeds 70 °C, the display screen will show
“INLET TEMP TOO HIGH”.

9. Maintenance
N.B. Maintenance work must only be carried out by a qualifi ed tradesperson familiar with instantaneous water heaters.
Plastic surfaces and sanitary fi ttings should only be wiped with a damp cloth.
Never use abrasive or chloric cleaning agents or solvents.
Outlet fi ttings (tap nozzles and shower heads) should be unscrewed and cleaned at regular intervals.
The electrical and plumbing components should be inspected regularly by a competent person to ensure proper functioning and opera-
tional safety. Water quality should be considered when determining the frequency of inspection.
Each time the appliance is emptied (e.g. due to work on the plumbing system, if there is a risk of freezing or in case of maintenance), the
appliance must be vented by opening and closing the hot water tap until all air has been eliminated from the water heater and no more
air emerges before re-connecting to the electrical supply.
10. Fault finding
Repairs should only be carried out by qualifi ed tradespersons familiar with electric instantaneous water heaters.
All service work should be performed by an authorized Zip service technician – for details of the full range of services available call Zip
Service on 1800 460 222.
When calling for service, please always specify the appliance model and serial number.
