STEP 1
Unpack the CO2 valve, you will notice a small bag that contains a small and large
seal. The large seal goes between the valve connection and the CO2 bottle. The
small seal is just a spare in case you lose the O ring between the bubble counter and
the valve.
STEP 2
Attach the CO2 valve to the bottle using the larger seal between the connection
and the bottle. Do not over tighten! I normally use an adjustable wrench with a
paper towel on the connection not to prevent scratches. Tighten in till the
connection is snug.

STEP 3
Unscrew the top of the bubble counter, fill the bubble counter approximately halfway
with either distilled/DI water or glycerin. You can find glycerin at a local drugstore. I
normally use water. The bubble counter also acts as a check valve to prevent water
from entering the main portion of the valve.
STEP 4
Connect the front portion of the valve,
screwing it into position,
Do not torque down this valve.

STEP 5
Close the needle valve underneath the square portion of
the valve.
STEP 6
Attach the solenoid, the small washer should be
positioned so that the center of the washer is pointing
down, hand tightened the small black nut. The warped
washer helps keep the solenoid from vibrating.
STEP 7
The solenoid can be plugged into a timer or pH controller, I always recommend a
pH controller if possible. The solenoid will allow CO2 to flow only when plugged in.
STEP 8
Double check that the fine adjustment knob underneath the square portion of the
valve is closed, open the valve on the CO2 bottle.
If the solenoid makes noise for any reason
just tighten up the black nut. Don’t be afraid
to tighten, but only by hand.

STEP 9
Adjust the front large knob on the CO2 valve to the desired output pressure. I normally
set the pressure around 40 or below.
STEP 10
Use the fine adjustment/ needle valve underneath the square portion of the valve
to adjust the output, you will notice that CO2 will start to bubble through the bubble
counter. The needle valve will allow you to make very fine adjustments. Set your
bubbles per minute.
If you suspect a leak use some soapy water in a small spray bottle to
quickly check the source of the leak.
