(40-100 ppm per the test), you can then start backing the WR-6035 pump speed setting down until it is
in a range where the residual dosage is specified (40-100 ppm). You will probably find that you will
step the WR-6035 pump down a couple of times until the dosage comes in range. Typically the final
setting of the 6035 pump will be around 150. Once set up, the system should take care of itself until
the chemicals are consumed.
Once the system has been passivated, prior to disconnecting the chemical pumps, they should both be
flushed by pumping water through them for a couple of minutes. Also, if there is any chemical left in
the drums, it should be carefully poured into a drain with flushing water, and the drums should be
rinsed out a couple of times as well. Also, you must replace the bung hole caps. When done,
remember to take “after” pictures of the same locations as the “before” pictures.
Some helpful points:
1. Mark the chemical level in the drum by time every so often in order to gauge how much
material you are using on a daily basis. The process should take 3-5 days, so if you are over
feeding, you may run out of chemical too quickly.
2. It is okay to overdose with the 6035 (better to overdose than under dose). It is not okay to get
the pH much below 6 in the system.
3. Use standard precautions when handling the chemicals. You should be wearing safety glasses
and rubber gloves and be aware of where the nearest eye wash station is in case needed. Also,
you should have a source of water available so you can rinse your hands or the area in case acid
is spilled.
4. If the chemical injection points are to remain on the system, install pipe plugs into the female
bushings after removing the chemical feed lines.
5. Tubing for pumps is 3/8” OD ¼” ID Polyethylene. If needed, you can get a 25 ft roll at Home
Depot.
6. You need 1/2'” female bushings for the injection nozzles from the pumps.
