Zip CEX-U Undersink Instantaneous Water Heater 6.6 - 8.8kW (Adjustable)

• 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

Minimum flow rate 2.0 litres/min. 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.

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. 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. The appliance must be installed in accordance with current IEE regulations.
