• Use polyurethane tubing to connect the regulator/iSOC® Distribution Header to the iSOC® making sure that the gas bottle has been cracked to avoid dirt or paint chips getting in the regulator or lines to the iSOC®. • Make sure that the tubing ends have been taped to prevent dirt in the lines as they are being installed.

Check pressure setting on regulator. Pressure should be set at 50 psi (3.4 bar) for water depths of less than 60 feet or 25 psi above the head of water for greater depths (33 feet of water = 14.7 psi and 10 m of water = 1 bar). Turn gas regulator knob clockwise to increase desired pressure.

Remove iSOC® unit from well. Check that unit produces a bubble at the rate of approximately one bubble per second when tested in a bucket of water. If it does, re-insert in well. If not, go to Step 2.
