5. Wait until all drainage stops. Then close all the drain valves that were opened in the previous two
steps.
6. When water stops draining from the drain tubes, disconnect each tube from its valve and hold the
end up to drain the residual water from the tube. Then reconnect the tube to its valve. (It is not
necessary to perform this step for a drain tube that is secured to its valve with a hose clamp.)
Chemical System
1. If the Bisulfite pump CP-1 has not been used, these procedures apply only to the antiscalant and
hypochlorite pumps.
2. Rinse the chemical buckets with product water. Partially fill one bucket and set back in place in
the operator's station.
3. Place the chemical pump suction tubes into the bucket. Be sure the suction tube inlets rest near
the bottom of the bucket.
4. Direct the return tube so that it drains to the ground. Do not place it in the pitcher.
5. Make sure that the speed control dial is set to OFF on each pump (turned fully counterclockwise).
6. If used, set the Bisulfite Pump switch on the OCP to ON. Set the Antiscalant/Hypochlorite Pump
switch on the OCP to ON.
7. Prime each pump as follows:
a. Turn the speed dial to 80.
b. After the pump has started, turn the stroke dial to 80.
c. Rotate the black knob on the priming valve one-half turn. Note that the water is drawing
up the suction tube, entering the pump housing and flowing out the return tube.
d. When primed, turn the black priming knob to its original position.
8. Operate each pump for 10 minutes to flush the pumps and the chemical tubing with product
water.
9. After 10 minutes, turn the speed dial on each pump to the OFF position (turned fully
counterclockwise).
10. Drain each system as follows (see Figure 5):
