2-10. OPERATING PROCEDURES (Contd).
Hypochlorite is caustic and can cause severe chemical burns To avoid injury
Wear required protective clothing any time you are handling calcium hypochlorite.
If hypochlorite solution comes in contact with skin or eyes, flush immediately with large
amounts of water, and seek medical attention
If hypochlorite solution spills on equipment, rinse with large amounts of water
Disconnect tubing (4) from discharge valve (5) by unscrewing tube nut (6)
As soon as liquid comes from discharge valve (5) and no air is trapped in pump head (7), shut outlet ball valve
Reconnect tubing (4) to discharge valve (5)
Open outlet ball valve (8) and allow hypochlorination unit to run for approximately 30 minutes, then perform
chlorine residual test, using test kit provided (refer to step d for details of procedure)
If residual reading is too high, turn stroke setting down to 3
(1) Allow unit to run for another 30 minutes and then repeat residual test (2) If reading remains high, lower
stroke setting again to 1.
(3) If reading remains high after another 30 minutes, double check estimate of flow rate and ensure that range
adjusting valve is in correct position (refer to step a. for correct position of range adjusting valve)
(4) If range adjusting valve is in correct position already and residual reading still remains high, dilute solution
at a 2 1 ratio, and start testing procedures over
(5) After desired chlorine levels are reached, go to Step r
