  • 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
    Installation

    The appliance must be installed in an environment which is free from frost at all times. 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. 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.

    Plumbing

    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.

    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. 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.

    Please note that this unit too powerful for connection to a 13A ring main and must be wired to the electrical distribution unit.
