7.3 Earthing
The unit MUST be earthed and a facility is provided for this in the unit design. You must
have the unit fitted by a suitably qualified installer – ESP accepts no responsibility for units
that are not fitted by fully qualified engineers. Further, failure to have the unit fitted by a
suitably qualified installer will invalidate the warranty/guarantee of the unit and may be dangerous.
7.4 Unit and System Controls
The control panel allows the user to view and alter system operating parameters. Other controls will be
necessary to control zone valves for solar or other auxiliary requirements.
7.5 Immersion Heater
The unit is supplied with a 1.5kW immersion heater as standard. This can be used as an alternative and/or
complementary heat source (see below) and is used to raise the temperature of the stored water to a
temperature above 60°C once a week (automatically) for an hour to remove any risk from Legionella
bacteria in accordance with EN 806.
