USUAL CONDITIONS
NOTE
Open one of the 12oz sodium bisulfite packets and pour it into the bottle provided in the
BII. The bisulfite powder will be used to neutralize the chlorine in the product water when
product water is required for flushing or cleaning.
c.
Fill the MF feed tank with product water from the product water distribution system by
connecting the end of a blue-banded product distribution hose to raw water Adapter A-05
and opening V-107.
d.
Using the bottle of bisulfite, fill the bottle cap with bisulfite twice and empty it into the MF
feed tank while it is filling with product water.
e.
When ready, set the SYSTEM MODE SWITCH to MF Fill/Hold.
f.
When the Standby Light comes on again, set the SYSTEM MODE SWITCH to Run.
g.
When the air compressor stops (or if already stopped), start the MF feed pump.
h.
Wait a few seconds and then push MF Backwash Start to manually initiate a backwash
using product water from the MF feed tank.
i.
When the back wash is complete, STOP the MF feed pump.
j.
Set the SYSTEM MODE SWITCH back to Standby.
NOTE
Make sure the RO Feed Tank level is at or below 50% before continuing. If it is not, open
RO feed tank main drain valve V-412 and drain water from the tank until the level drops to
50%. If you proceed to the second backwash with a high RO feed tank level, the RO tank
will overflow during the second backwash.
3. Backwash the MF with product water a second time and fill the RO feed tank as follows:
a. When the air compressor stops again, set the SYSTEM MODE SWITCH to MF Fill/Hold.
b. When the Standby Light comes on again, set the SYSTEM MODE SWITCH to Run
c. Start the MF Feed Pump, wait a few seconds and push MF Backwash Start to manually
initiate a second backwash.

automatically when the RO feed tank is filled.
4. Flush the RO with potable water as follows:
a. Reset any alarms and then start the RO feed pump
b. Turn the SYSTEM MODE SWITCH to STANDBY. The PLC automatically performs the
following actions:
1) The automatic valves are cycled to the standby position.
2) The RO feed pump remains ON to flush the membranes until the RO feed tank
empties. The low level alarm will sound when the tank is empty and the pump
will stop.
5. Complete the drain-down after the RO feed pump turns off as follows:
a. Set SYSTEM MODE SWITCH to MF DRAIN.
1) The PLC automatic control purges the water from the MF using air.
2) The automatic valves return to Standby position at completion.
b. After one minute return the SYSTEM MODE SWITCH to STANDBY.
c. Move the drain and vent valves the position listed in Table 2 (refer to Table 2 for valve
position and Figure 3 to locate the valves).
d. Continue with the draining of the Raw Water and Distribution Systems as required.
