Appendix G: Connecting AutoFill to Plant Water
The AutoFill Accessory Kit is provided to facilitate connecting plant DI water to the AutoFill hardware of your system. The accessory
kit includes a 5 micron particulate filter, an adjustable pressure regulator, 10 feet of 6 mm OD polyethylene tubing, and the fittings
necessary to connect the components.
Determine the most convenient locations for the pressure regulator and particulate filter. The regulator assembly is connected directly
to plant water, with the particulate filter between the regulator and the AutoFill port on the side of your system.
Based on the filter and regulator locations, cut three pieces of the provided poly tubing to appropriate lengths. One piece connects
the plant water to the regulator, the second piece connects the outlet of the regulator to the inlet of the particulate filter, and the third
piece connects the outlet of the particulate filter to the AutoFill inlet on the side of your system.
Assemble a male quick-disconnect fitting to one end of the tube from the filter to your system and to one end of the tube from the
regulator to the filter. Refer to image below.
Install the tube from the regulator to the filter by sliding the open tube end into the push-to-connect fitting at the outlet of the
regulator and clicking the other end of the tube into the inlet of the particulate filter.
Repeat the step above for the tube from the filter to the inlet port on your system.
Remove the red plug from the AutoFill inlet port on the side of your system and insert the line from the outlet of the filter.
Fully turn the regulator adjusting knob counter-clockwise and connect plant water to the AutoFill. Adjust the regulator to obtain a
maximum of 30 psi water pressure. Verify that there are no leaks.
