4. OPERATION
PURELAB flex 3 & 4 provides high purity water typically where daily usage does not
exceed 10 liters/day.
To provide the ultimate purity, water is re-circulated through a range of treatment
technologies and stored in an internal reservoir.
The reservoir is filled automatically from either a potable water or pre-treated supply.
Please refer to Section 9. Technical Specifications for details.
During periods of non-use the unit will automatically operate in intermittent (10 minutes
every 2 hours) re-circulation mode to maintain water purity with maximum efficiency.
Refilling of the reservoir is determined by usage and achieved in the following ways;
1. AUTOMATIC REFILL. When the water level in the reservoir reaches <4 liters the
PURELAB flex will begin to refill. An option in main menu allows ‘Refill set point’ to
be adjusted. Follow instructions on the Dispense handset.
2. INITIATING A RESERVOIR REFILL. Pressing the Initiate Reservoir Refill button on
the display handset for 2 seconds.
3. MANUAL REFILL. Water added directly into the reservoir by removing the
Composite Vent Filter.
4. TIMED AUTO REFILL. The timed auto refill is a feature downloadable from the
website (only available when the clock feature is selected). The timed auto refill
allows the user to set a time at which the system will automatically enter a refill
cycle. With Auto Refill set to 16:00 the unit will enter refill cycle at 4pm everyday.
The Quick Reference Guide shows you how to perform day to day functions in order to
get the most from your PURELAB flex without having to refer to this Operators Manual.
