OPERATOR INSTRUCTIONS
INITIAL START-UP OR START-UP WITH THE SYSTEM FULLY DRAINED
OPERATION UNDER USUAL CONDITIONS
a. With the product utility hose, fill the Hypochlorite bucket with product water to the 4-gallon
level.
b. Rinse the mixing paddle with product water from the product utility hose.
c. Pour the required quantity of hypochlorite into the hypochlorite bucket and mix using the
mixing paddle. Mix until the hypochlorite is dissolved.
d. 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.
e. Turn the speed dial on the chemical pump to 80, note that the pump has started, and
then rotate the stroke dial to 80.
f. Rotate the black knob on the priming valve one-half turn.
g. Note that the chemical solution is drawing up the suction tube and entering the pump
housing.
h. 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.
i. Set the stroke and speed as listed in Table 3 through Table 5 for the expected product
flow rate and the free chlorine concentration required.
j. Turn the Antiscale/Chlorine switch on the OCP to AUTO.
COMPLETING START-UP
1. If the product flow is less than the normal 20.5 to 21 gpm or 25.5 to 26 gpm and cannot be
adjusted to the normal product flow rate, refer to Table 3 through Table 5 and change the
hypochlorite pump speed (strokes/min) and stroke length settings as listed for the flow rate and
required free chlorine concentration. If the flow is between two listed flows, use the higher flow
setting.
2. Before connecting the product hose to the distribution tank, refer to WATER QUALITY
Portable Chlorine Test Meter (MC-TWPS) or the WQAS-P chlorine test kit (A-TWPS).
3. Connect the product water hose (from the TWPS product water discharge) to the distribution
tank.
4. Check the MF feed tank. Just before a backwash it should be approximately 3/4 full. If low,
slightly open raw water flow Valve V-107.
5. Refer to WP 0016, Maintaining Normal Operation; complete the Operator's Data Log and check
that all readings are within normal values.
