The first best choice to go for support of a new purchase is the place you bought it from to avoid any potential conflict between what is said here and what they may tell you. Someone there will be glad to walk you through it on the phone if needed I'm sure.That being said, here we go:
1) Get your controller set up:
a) Remove the rubber cap from the controller probe and thoroughly rinse the crud off with distilled water, connect it to the controller, when (not yet though) you put in your tank, try to keep the water line at or below the black collar on the probe, it's water resistant, not water proof at the point the cable goes into the probe.
b) Connect the AC adapter to the controller, and plug the controller into an outlet that is on24/7.
c) Plug the controlled outlet into an outlet that again is on 24/7
d) Turn the controller on and place the probe into the packet of 7.01 calibration solution, let it set for a mnute or so and turn the controller on.
e) Using the screwdriver included with the unit and the adjustment screw on the FRONT of the unit, adjust the pH reading on the controller to 7. Do not touch the adjustment screw on the back of the unit. Turn the unit off.
2)Connect your regulator to the CO2 cylinder:
a) Connect the regulator to the CO2 cylinder, making sure to use one of the included washers between the cyclinder and regulator, don't use teflon tape on the threads, just screw it onto the cylinder and CRANK DOWN AS TIGHT AS YOU CAN !
b) Plug the regulator solenoid valve into the controlled outlet of the controller.
c) Turn the gas valve on, opening it until it hits the stops, this is to ensure there is no leak at the valve itself. Use a soap solution to check the connection for leaks at the cylinder.
d) Unscrew the bubble counter cap and fill approx. 2/3 full of water (I use tap water, some use distilled, other's use a special fluid, the choice is yours really, water works fine for most) and replace the cap.
e) Unscrew the retaining collar on the compression fitting on top of the bubble counter and slip it over the end of your CO2 tubing, slip the tubing over the nipple and screw the collar back down snug. Connect the other end to whatever you're using to inject the CO2 into the tank.
a) Make sure the needle valve on the regulator is closed, place the probe into your tank, don't submerse it beyond the black collar (water resistant, not water proof), usually somewhere so it's in the out flow stream of your filter, I put mine about 2' from it.
b) Turn the controller on, and using the numbers on the control dial as a general reference, set the dial slightly above your desired pH level and set the bubble rate as desired with the needle valve, how fast depends on your water and injection method, I suggest a slow rate at first, maybe 1 every two seconds to avoid rapid dropping of the pH at first and tweak it from there as needed.
d) an alternate method is to turn the pH down until the controller kicks in and turn it back up a bit and let it set like that until it kicks off, and repeat until you hit your desired pH level.
Hope that helps, but like I said, don't hesitate to call AP, someone there will be glad to walk you through it I'm sure if this isn't clear enough or PM me and I'll be glad to give you my number and help you as well.
