BREAK TANK TEMPERATURE HIGH LIMIT set-points. When these set-points are
reached the water to drain period will begin and the RO will dump water to
drain. During times of low water usage in the RO distribution loop, the feed
water quality in the break tank will remain close to incoming water quality. See
Section 6.4.1 for more information.

Water to Drain:
Reject water is dumped to the drain until the
permeate quality reaches the HI RECOVERY QUALITY
LOW LIMIT or BREAK TANK TEMPERATURE LOW
LIMIT set-point. Valve position will remain the same
for Loop Return and Product to Loop Valves. The
Concentrate to Drain Valve will rotate as shown in
Figure 7.

Standard Recovery Mode
Standard Recovery Mode is also comprised of Flush, Rinse, and Supply mode.
Flush and Rinse operations remain the same, see Figures 1 through 3. However,
when operating in Standard Recovery Mode, there is no Reject to Tank step of
Supply. There will be more water usage due to less water being recovered during
this period. See Figures 4-6 for valve positioning.

Heatsan Fill Procedure
The MediQA can be called on to provide water to the Heatsan. Be sure that MINT
cable is connected between MediQA and Heatsan for fill procedure to function.
