Disinfection Step by Step - 2 (running a routine cycle)
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'.
2. Click 'Arm'.
3. Click 'Trigger'.
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.
5. Click 'Cool Down'.
6. Draw-off hot water from the blend circuit. Use either the last outlet on the circuit
or a dump valve tted near to the end of the circuit.
7. When DRV40 temperature is within normal operation, stop the draw-off.
8. Allow the DRV40 to return to normal operation automatically.
MAKE SURE ALL OUTLETS ON BLEND CIRCUIT
ARE NOT IN USE UNTIL CYCLE IS COMPLETE!
No one should be allowed to approach within 3 metres of any affected outlets.
IMPORTANT! - CHANGES TO THE PLUMBING SYSTEM.
Any alteration to the plumbing system that may affect the blend circuit may, as
a consequence, also affect the Disinfection Timeout period. Repeat all steps
in 'Step by Step -1' to maintain a reliable disinfection cycle for the system.
