OVERVIEW
Congratulations on your purchase of our carbon dioxide (CO
components make it the best CO
against the diagram and components listed below.
SETTING UP YOUR SYSTEM
1.
IMPORTANT! Before attaching the regulator to the
CO
tank, slowly open the tank valve wide for 3-5
2
seconds to blow out any sediment. Close the valve
tightly. Whenever you are opening the tank valve,
do it extremely slowly to avoid damaging the
inner seals in the regulator.
2.
Make sure the included black O-ring is present and
seated evenly in the regulator valve. It is there to
prevent leaks. Replace the O-ring with each tank
change. This will ensure a tight fit, without leaks,
each time. Replacement O-rings can be purchased
at your local indoor gardening store (item code:
CORING).
3.
Securely attach regulator assembly to tank. Use a
crescent wrench to make this connection. Do not
use pipe thread tape or lubricants when making
the connection to the tank. Do not use pliers or channel-locks to tighten the nut. Do not overtighten the nut.
DO NOT OPEN THE TANK VALVE YET.
NOTE: When attaching the regulator to the tank, do not hold on to the clear plastic meter. Putting pressure
on the clear plastic meter will break the seal at the base and permanently damage the unit. This will not be
covered under the warranty.
4. Insert the shorter extension tube into the plastic fitting on the back of the flow meter.
5. Insert the other end of the extension tube and insert it onto the "T" fitting.
6. Do not touch the solenoid during or for at least 5 minutes after operation, as it can reach temperatures of
80°C/176°F.
ATTACHING THE DISTRIBUTION RING
The distribution ring is designed to be suspended above the plants in a circular pattern.
1. Screw in the eyelets according to the diagram.
2. Thread the tubing through the eyelets in a circular pattern over your growing area.
3. Connect the return end to the other side of the "T" fitting. CO
from the distribution points. Make sure the distribution tubing is secured and does not interfere with your
lighting or light movement systems.
NOTE: If you opt not to use the distribution ring, connect a 1/4" tube to the regulator and run the tube into
the grow room, then zip tie the tube to the back of a wall mount fan to disburse the CO
using the 12" Pivot Fan (item ACFV12HD) to blow air back up towards the ceiling. This will help keep the CO
circulation.
ADJUSTING THE REGULATOR
1.
Before opening the valve on the CO
adjustment knob on the regulator to relieve the pressure from the gas being released. Failure to do this can
permanently damage the unit and void the warranty.

3.
To set the flow rate, turn the black flow rate adjustment knob. The ball will move up and down inside the
meter tube. Adjust the knob to your desired flow rate.
