OPERATION
CENTRA
has the following modes of operation:
•
Continuous Recirculation (24/7).
•
Night service/Operational day.
•
Sanitization Cycle (See Section 10 - Sanitization
Procedures).
7.1
Night service/Operational day
Refer to Section 5.2 - Step14 and 15.
CENTRA
can be programmed to operate on specific days between
selected times. This feature is designed to optimize the efficiency
of the product as well as minimizing rise in water temperature.
During the ‘sleep’ period the unit will display the STANDBY icon.
It is possible to override this mode by PRESSING the PROCESS
button.
CENTRA
will continue to operate until the next ‘sleep’
period is reached.
During the ‘sleep’ period the unit will run in intermittent recirculation
(10 minutes every two hours) to maintain water purity around the
distribution loop.
7.2
Continuous Recirculation (24/7)
Refer to Section 5.2 - Step 13.
If the unit is set to continuous recirculation, it will constantly
recirculate the water and fill the reservoir as required.
It is recommended that the system be run in continuous mode only
when the demand for water is sporadic and overall usage is high,
>50l/hr.
During the recirculation the water temperature will rise slowly. The
rate of rise will depend on the length of the ringmain and local
factors.
To control the rise in water temperature it is recommended that the
system be operated in night service/operational day mode which
will stop recirculation occurring during periods, such as overnight
or at weekends when water may not be required.
CENTRA RDS/RDS US (HF)
include a temperature flush
sequence to assist with water temperature reduction.
