5.0 EXPLANATION TO USER 

The Multipoint SS unvented heater stores water at the temperature set on 

1. 

the adjustable control knob. This can be set to give temperatures in the 

range 10°C to 70°C. In hard water areas it is advised that the maximum 

temperature is restricted to prevent build up of scale. To avoid risk of 

freezing when the heater is not in use for long periods during the winter 

months, do not switch off the electrical supply and set the thermostat to 

its minimum position. N.B. This will not protect other system pipework.

The indicator lights will be illuminated when the unit is heating.

2. 

To ensure the heater continues to operate at its optimum performance 

3. 

it should be periodically maintained in accordance with the instructions 

given under the section headed MAINTENANCE.
