III.2 Filling Procedure
Remove the front compartment panel by turning the two black fasteners ½ turn
counterclockwise. Tilt the panel out from the top, then lift up to remove it. See
Figure 9
for valve locations. Including the filters, the total capacity is 55 liters
(14.5 gallons). Refer to one of the following sections depending on the type of
Vigon SC200 being used.
CAUTION
: When filling the machine, chemical protective gloves and eye
protection should be worn.
Filling with SC200 Concentrate
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 DI water. Carefully replace the filter housing,
making sure that the O-ring is fully seated in the groove. Thread 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. Hold the cartridge down while filling the filter housing up
to the O-ring groove with DI water. 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 tank valves
V1
and
V2
fully.
Measure out the proper amount of Vigon SC200 for the desired dilution. For a 25%
solution, this is about 14 liters (3.6 gal.). It is helpful to use the supplied siphon
pump to dispense the concentrate into the measuring vessel. Using a funnel, pour
the concentrate into the rear tank of the machine. With a hose, fill the machine with
DI water into the rear tank until it overflows into the front tank 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. See Section
III.3
for starting procedures. When starting the machine for the first time, it will take a
short time for the pumps to prime. Allow the pumps to run for about 10 minutes to
mix the solution thoroughly before use.
