For fresh waters with a turbidity of less than 8 NTU and color greater than 10, polyetectrolyte is not required. Proceed
to para. 2-17b, "Establishing Water Flow".
Empty the five gallon can of water into the polyelectrolyte tank.
Make certain hypochlorite and sequestrant pumps are OFF.
This action removes air from chemical system and allows polyelectrolyte to be pumped.
Push CHEMICAL PUMP START (2).
Set speed control knob (3) to 80 and record.
Set stroke control knob (4) to 100 and record.
Pull out and hold priming knobs (5) until solution is being pumped out though discharge tubing to drain.
Tip the polyelectrolyte jug to fill measuring chamber to 8 oz. (236 ml). Empty measuring chamber into the
Repeat to add one more 8 oz. (236 ml) measure and then a final 4 oz. (118 ml) measure for a total of 20 oz. (591 ml).
For mission start-up use 20 oz in 5 gallons water (4 oz. in one gallon).
Vigorously mix with mixing paddle for 2 minutes. By visual observation, make sure all polyelectrolyte is in solution. Use
caution while mixing to avoid hitting the fittings or switches in the bottom of the tank.
Reset the speed (3) and stroke control knobs (4) and record. See Table 2-17.
The settings provide an initial adjustment only. Further adjustment of polyelectrolyte
injection will be required after the sequestrant and hypochlorite systems are set-up and
