6) MEASUREMENT OF CONCENTRATION & GUIDE TO TIP SELECTION
The water-to-product ratio is calculated using the number of ozs. of chemical concentrate drawn by the
proportioner to produce a measured volume of mixed solution. Select a metering tip, using the chart
above as a guide. Place the foot valve in calibrated container Afilled with chemical concentrate. Prime
the proportioner by operating such that the suction tube is filled completely; then discard the discharge.
Refill container A, noting volume in ozs. Operate unit and collect mixed solution in large container B.
Record final volumes in ozs. of both containers. Determine the number of ozs. of concentrate drawn
from A. Calculate Xwhere X is equal to:
(Total ozs. mixed solution in B) - (Total ozs. concentrate drawn from A)
(Total ozs. concentrate drawn from A)
The water-to-product ratio is then X:1 or Xparts water to one part concentrate. If the desired ratio was
not obtained, select a different tip and repeat the procedure.
Alternate methods to the above are pH test or titration test. Consult your supplier for further information
on these methods.
7. OPERATION
Open the water supply and shut-off valve (MM3). When the solution in the reservoir reaches the level
set by the float, the valve will close. This will stop the water flow and siphoning of concentrate. When
withdrawal of solution from the reservoir causes the level of solution to drop more than 11/2!inches the
valve will open and the reservoir will be refilled to the previous level. This cycle will be repeated
automatically until the supply of concentrate is depleted. The shut-off valve should be fully closed when
changing metering tips or chemical concentrate, when the reservoir is drained, or when the unit is not in
use.
Your MAGIKMINDER can be used with water soluble powders and granulated materials by filling a
reservoir with warm to hot water and dissolving as much powder as possible until precipitate
(undissolved chemical) forms on the bottom. This mixture can then be proportioned. However, it is very
important to keep the suction strainer off of the bottom of the reservoir so that solid chemical does not
plug up the suction strainer, especially when the solution cools off after mixing. "
