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.

2. Antifoaming Agent (AF-20) The antifoaming agent inhibits the formation of
bubbles and deodorizes the wastewater. The antifoaming agent, in addition
to using the Air deodorization equipment (RDS-20), enhances the
deodorization effectiveness of the lens dust filtering system.
- Before or during lens processing, put 2 cups of AF-20 into the Lens edger
and wastewater tank to reduce bubble generation.

RDUM-100, Rev.1Rodek Co., Ltd.
before using the antifoaming agent after using the antifoaming agent
▶If you use AF-20 : The sludge will settle at the bottom of the
wastewater tank and will be transferred to the filtering equipment by the
filtering pump.
If you don’t use AF-20, the microplastics will stick to the bubbles in
the wastewater and will not settle at the bottom of the wastewater tank.
※To reduce wastewater odor, put 2 cups of the antifoaming agent into the
wastewater tank.

Ⅹ. Precautions
Please check one more time before using this
product.
To maintain the performance of this product, please take note of the
following.
PrecautionsIf you fail to follow the precautions:
Be sure to install the A.V filter and
HEPA filter.
Without the A.V. and HEPA filters, the RDS-20
cannot remove odors, and the lifespan of the
activated carbon could be substantially shortened.
R
eplace the Activated carbon
cartridge annually or after edging
approximately 10,000 lenses.
If the Activated carbon is blocked, the
deodorization performance could be substantially
reduced.
The activated carbon cartridge replacement time
could vary depending on the type of lens
processed.
Be sure to connect the air
deodorization equipment hose
properly.
If there is
a breach in the connection between the
wastewater tank and the air deodorization
equipment, odor may leak out of the system.

18
RDUM-100, Rev.1Rodek Co., Ltd.
Don’t damage the deodorization
hose.
A damaged hose will cause odor leaks.
Use only the antifoaming agent
supplied by Rodek.
If you use anything other than the specified anti
foaming agent, excessive bubbles may form which
may cause device problems.
Please do not put coagulant into
this dust filtering system.
If coagulant is put into the system
, it may cause
pump or filter failure.
Please maintain the temperature
around this product over 0℃.
If the temperature around the product in winter is
below 0℃, the water in the product may freeze and
it may cause device failure.
Please check the water level in the
wastewater tank.
If the water level in the wastewater
tank is too
high, bubbles can be circulated in the system in
large quantities, blocking the wastewater f
ilter and
activated carbon air filter.
If the water level of the wastewater tank is too low,
the wastewater temperature can rise, causing water
vapor generation and blockage in the wastewater
filter and activated carbon air filter.
