The feeder assembly consists of coiled capillary tubing with a probe, a weight, syringe and a clamp
Each Feeder is calibrated at the factory to assure accurate feeding
The distance that the weighted end of the capillary tubing is allowed to hang below the middle of the treatment bottle determines the feed rate
This distance is referred to as feeder head, (H) and should always be measured from the middle of the installed treatment bottle to the end of the capillary tubing
After the bottle of treatment has been hung at the proper height, the coil of tubing should be placed around the neck of the bottle
Feeders are shipped with "H" set at 40 in
To establish the proper feeder head, as specified in the application charts, simply uncoil the tubing to increase "H" or coil excess tubing to decrease "H"
