Filling with SC200 25% Premix
NOTE:
The SC200 Premix tends to separate during storage. It is essential that the
container be shaken or stirred with a mixing device
each time
before dispensing the
product to ensure uniformity.
Remove the short filter housing by turning to the left (counter-clockwise.) Use the
supplied filter wrench if necessary. Install a new O-ring. Next, fill the filter
housing up to the O-ring groove with the
stirred
SC200 premix. (Use the supplied
siphon pump for this task.) Carefully replace the filter housing, making sure that the
O-ring is fully seated in the groove. Thread the lower housing into the top housing
and tighten securely (hand tight.)
Remove one of the long filter housings by turning to the left (counter-clockwise.)
Use the supplied filter wrench if necessary. Install a new O-ring. Place a filter
cartridge in the housing. While holding the cartridge down, fill the filter housing up
to the O-ring groove with the
stirred
SC200 premix. The filter will tend to float
upward. Position the long housing under the top housing. Seat the filter on the boss
in the top housing, raise the filter housing, rotate to the right to thread it into the top
housing, and tighten securely (hand tight.) The filter will eventually seat itself on
the boss in the lower housing. Repeat for the other long filter. Open the tank valves
V1
and
V2
fully.
Again using the siphon pump, dispense the
stirred
SC200 premix into the rear tank
until it overflows into the front one and fills it to within three inches of the top.
The filters have bleed valves at each outlet (on the right sides of the long housings)
to help remove air when filling. (These are quarter-turn polypropylene ball valves.)
Open the left bleed valve fully. When fluid begins to flow from the bleed valve,
quickly close it. Open the right bleed valve. When fluid begins to flow from the
bleed valve, quickly close it. The machine is now ready to start.
When starting the machine for the first time, it may take a short time for the pumps
to prime.
Measuring Solution Concentration
The concentration of SC200 in the cleaning fluid may be determined by using a
handheld refractometer. The suggested range of the refractometer to use is 0 to 30
Brix. A Refractive Index chart is included in this manual to convert the Brix
reading to percent concentration. The solution concentration should be checked
periodically to ensure it is at least 25%. When checking the solution, allow the
pumps to run for at least ten minutes to ensure that the SC200 is thoroughly mixed
with the water. Draw the sample from several inches below the surface and drop it
immediately on the refractometer lens to get the reading.
