You are about to run a disinfection cycle of the blend circuit. Before you begin,
make sure there is an adequate supply of hot water for the cycle. You will also
require a reliable clock or stopwatch to monitor the duration of part of the cycle.
Make sure all warnings, cautions and responsibilities on page 28 are observed
during the cycle.
1. Click 'Off' under 'Valve Control' .

4. Start the stopwatch or note the time of day. Monitor the temperature and time
until a satisfactory disinfection of the blend circuit has been achieved.

'Cool Down'
.
6. Draw-off hot water from the blend circuit. Use either the last outlet on the circuit
or a dump valve fitted near to the end of the circuit.
