OPERATOR INSTRUCTIONS
INITIAL START-UP OR START-UP WITH THE SYSTEM FULLY DRAINED
OPERATION UNDER USUAL CONDITIONS
PERFORMING PRE-OPERATIONAL DIAGNOSTIC SELF-TESTS
Perform the pre-operational diagnostic self-test procedure (built-in-tests or BIT) as described in WP 0013.
SODIUM BISULFITE CHEMICAL SYSTEM START-UP
CAUTION
If the raw water source is chlorinated water or well water, the sodium bisulfite chemical
system must be set up and started before raw water flow is established. Failure to provide
sodium bisulfite injection will result in the destruction of the MF and RO membranes.
NOTE
If the raw water source is NOT chlorinated water or well water, skip this procedure and
move on to ESTABLISHING RAW WATER FLOW WITH BOTH RAW WATER PUMPS or
ESTABLISHING RAW WATER FLOW WITH ONLY THE ELECTRIC RAW WATER PUMP,
depending on how you set up the raw water system.
If the raw water source is chlorinated water or well water, start-up the sodium bisulfite chemical system as
follows:
1. Make sure that the sodium bisulfite injection system has been deployed as described in the
procedures for SODIUM BISULFITE INJECTION SYSTEM DEPLOYMENT in WP 0010, Other
Set-Ups Operation Under Unusual Conditions.
2. Set the Bisulfite Pump switch on the OCP to ON.
3. Make sure that the speed dial on the sodium bisulfite chemical pump is set to OFF (fully
counterclockwise) (see Figure 3).
4. Fill the bucket with the blue cover with raw water to the 5-gallon level.
WARNING
Hazardous chemical dust and/or fumes. Wear the protective face shield, chemical gloves,
and a dust mask when handling sodium bisulfite. Avoid inhaling chemical dust or fumes.
Failure to observe this warning may result in irritation of the nose, throat, eyes, and skin.
5. Rinse the mixing paddle with raw water.
6. Pour one 12-ounce packet of sodium bisulfite into the bucket and mix with the water using the
mixing paddle.
7. Place the chemical injection pump suction tube and return line hose through the cover hole and
into the chemical bucket. Be sure the suction hose inlet rests near the bottom of the bucket, but
not flat on the bottom.
8. Turn the speed dial on the chemical pump to 80, note that the pump has started, and then rotate
the stroke dial to 80.
9. Rotate the black knob on the priming valve one-half turn.
10. Note that the chemical solution is drawing up the suction tube and entering the pump housing.
11. Rotate the black knob on the priming valve back to its original position when discharge is noted
back to the tank and air is not noted in the suction tube or the pump head. The pump is now
primed.
12. Set the speed dial to 70%.
