With the control set as above, the solution in the holding tank can be brought to the required strength by recirculating for
the hours indicated in the General Specifications (Page 3) (IF THE DC AMMETER IS NOT READING 950 TO 1000,
INCREASE THE SALT LEVEL. IF THE DC AMMETER IS PEGGING TO THE FAR RIGHT, DILUTE AS NECESSARY.)
An alternate approach to the above is to add a predetermined amount of Commercial hypochlorite to the tank in addition
to the salt. This will eliminate the initial build-up time. For example: 20 gal. of a 5 1/4% Commercial Hypochlorite
(bleach) added to 180gal. of 12 salometer brine will provide initial stock solution containing 6000 ppm C12.
Optimum operating conditions exist when the holding tank solution temperature is in the 75
95 F. range. This
can be accomplished by proper adjustment of the heat exchanger.
To place the exchanger in operation proceed as follows:
Connect a suitable length of tubing to the fitting marked "Drain", on the right side of unit near center of heat
exchanger flange. Place other end down into the closest drain. Adjust flowmeter so that approximately 80 gph water @
10 PSI is flowing through the cooling chamber; however, local climatic conditions will determine the final flowrate. For
example, a seasonal rise of thirty or more degrees Fahrenheit is not uncommon in locations where the Plant water is
from a river source. THEREFORE, TO STABILIZE THE SOLUTION TEMPERATURE, A BI-YEARLY ADJUSTMENT
SHOULD BE MADE, I.E., A HIGHER FLOWRATE IN THE SUMMER, LOWER IN THE WINTER.
