CHECKING AND REFILLING THE ANTISCALANT CHEMICAL SYSTEM
WARNING
Irritant. Wear a protective face shield and chemical gloves when handling
antiscalant chemical. Avoid inhaling chemical fumes. Failure to observe this
warning may result in irritation of the nose, throat, eyes, and skin.
1. Check:
a. The chemical pump is set to pump 4.2 to 5 gallons during a 10-hour operating shift.
b. The chemical level in the bucket should be observed to make sure that it drops a little
less than 1/2 gallon per hour. If this is not observed, refer to troubleshooting in WP 0033.
2. Refill:
a. Refill when the remaining level is between the 1/2 and 1-gallon marks on the bucket.
b. Fill the AC-110 measuring cup with AC-110 antiscalant to the 650 milliliter level.
c. Using the product utility hose, open valve V-511 to slowly fill to the bucket to the 5-gallon
level. At the same time, slowly add the antiscalant.
d. Rinse the paddle with water from the product utility hose. Stir the water in the bucket with
the mixing paddle to thoroughly mix in the antiscalant. Be careful not to damage the
suction strainer. Rinse the paddle again when finished.
3. Pump Settings: The pump settings are the same for all conditions.
a. Speed 70
CAUTION
The stroke length should only be adjusted when the pump is running.
b. Stroke 60
4. Check the pump prime:
a. Check that the pump return line hose is directed into the tank.
b. Rotate the black knob on the priming valve counter-clockwise one half turn and check
that the chemical is discharging through the pump return line hose. If not observed, refer
to troubleshooting in WP 0033.
c. Return the black knob on the priming valve to its normal position.
CHECKING AND REFILLING THE HYPOCHLORITE CHEMICAL SYSTEM
WARNING
Hazardous chemical dust and/or fumes. Wear the protective face shield, chemical
gloves, and dust mask when handling calcium hypochlorite. Avoid inhaling
chemical dust or fumes. Hypochlorite will give off chlorine vapor, which will burn
your nose, throat and lungs if breathed directly. Keep your head away from top of
the bucket while filling. Inhalation of calcium hypochlorite dust may cause severe
chemical burns. Direct contact with the eyes may cause severe eye damage.
