Flushing the
Membrane
Thermo Scientific
Normal Operation
Section 7
Below is a brief description of the normal automatic operation of the
Thermo Scientific RO system. If the unit does not operate as described
below, refer to the troubleshooting guide.
When the main power switch is activated, the following events will occur:
1. All LEDs will flash sequentially, to indicate that they work.
2. After approximately 5 seconds, the solenoid valves are energized. The
inlet valve opens, supplying the RO system with water. The flush valve
also opens, diverting the water to drain.
3. After 30 seconds, the flush solenoid valve closes and the RO system
begins making product water and sending it to the storage reservoir.
4. The microprocessor tracks operating time and at a pre-selected interval
illuminates the "replace carbon filter" light, signifying that the carbon
cartridge should be replaced.
5. When the reservoir is full and the RO system is in Standby mode, a
clock is activated, which energizes the RO system for 4 minutes every
3 hours and 56 minutes. This ensures that water will not stagnate on
the membrane surface. The majority of the water produced during this
4 minute cycle will divert to the drain.
Note The Reverse Osomosis System flushes automatically in Standby for 4
minutes, after 3 hours and 56 minutes in Standby (reservoir full). This
prevents stagnant water from damaging the membrane. A flush can also be
initiated manually.
