Ⅴ. Installation
1. Wastewater tank installation
1) Place the filtering equipment base in the desired location.
2) Install the wastewater tank as follows:
2-1) Place the wastewater tank on the filter base and fill it with water
up to the marker.
2-2) Assemble the Air deodorization equipment hose connector on
the filtration tank cover.
2-3) Assemble the filtering pump.
2-4) Assemble the rest of the parts as follows:
2-4-1) Secure the wastewater tank mesh filter to the
wastewater tank cover top panel. Do this by aligning
the bolts on the wastewater tank filter to the
corresponding holes on the wastewater tank cover
top panel. Secure using the provided nuts.
2-4-2) Bolt the wastewater inlet port onto the filtration
tank cover top panel.

2. Filtering equipment installation
1) Place the stainless-steel wire mesh filter at the bottom of the inside
of the filtering equipment.
2) Check the dimensions of the plastic mesh filter and place it inside
the filtering equipment as shown in the figure.
2-1) The plastic mesh filter is an isosceles trapezoid. The longer of the
two parallel sides should be the top side during insertion.
3) Place the filter (RFS-20F) inside the filtering equipment. See to it that
the filter closely conforms with the inside of the filtering equipment.
4) Lock the filter in place by inserting the locking ring inside the filter
as shown in figure 4.
5) When you insert the locking ring, do not block the wastewater inlet located
at the top of the filtering equipment. Fold the portion of the filter that is above the
locking ring downward into the inside of the filter.
6) When you insert the filter, the bottom of the filter should reach the
stainless-steel wire mesh filter that you placed in step 1 above.
7) Close the lid of filtering equipment and tighten the locking
mechanism clockwise.

Ⅵ. How to use the coagulant the and antifoaming agent
1. Coagulant (AP-20): The coagulant absorbs the remaining moisture in the
sludge, thus making the sludge easier to handle and dispose of.
To use the coagulant:
1) Turn off the filtering pump and loosen (turn counterclockwise) the
locking mechanism of the lid of the filtering equipment.
2) Remove the locking ring. See Chapter 2 for locking ring details.
3) Remove the filter from the filtering equipment and move it to a
prepared container.
4) Put 2~3 spoons of the coagulant (AP-20) into the container. Mix the
coagulant with the sludge and wastewater thoroughly in order to speed up
coagulation.
6) Dispose of the solidified sludge in a standard plastic garbage bag.
