SETTING UP YOUR SYSTEM

1. IMPORTANT! Before attaching the regulator to the CO

tank,

slowly open the tank valve wide for 3-5 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 washer is seated evenly in the regulator valve.

Insert one of the provided white plastic washers inside the large

brass nut. This will help prevent leaks. Replace the white plastic

washer with each tank change. This will ensure a tight fit, without

leaks, each time. Rubber replacement washers can be purchased

at your local indoor gardening store (item 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.

is heavier than air and will spread downward 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

. We also

recommend using the 12" Pivot Fan (item ACFV12HD) to blow air back

up towards the ceiling. This will help keep the CO

in circulation.

ADJUSTING THE REGULATOR

1. Before opening the valve on the CO

tank, slightly open (1/2 turn

counter-clockwise) the black flow rate 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.

2. Open the valve on your CO

tank 2 or 3 rotations. Check for CO

leaks at all connections by using soapy water.

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. WARNING: Opening the black

dial completely, where the ball moves past the top of the flow

scale, can allow the CO

to flow too fast. This can cause freezing

of the regulator and will void the warranty.

If the psi (pounds per square inch) gauge doesn't read between 20

and 30 psi when the regulator is securely attached and set up, and

the tank is full, adjustment will be necessary. Remove the green

"CO

" sticker on the front of the unit (if applicable). Adjust the bolt

found under the sticker until the gauge reads between 20 and 30

psi. You will need a 4mm (5/32") hex key or a flat head screwdriver,

depending on which model you have.

SETTING UP YOUR SYSTEM

1. IMPORTANT! Before attaching the regulator to the

CO2 tank, slowly open the tank valve wide open for 3-5

seconds to blow out any sediment that may be in the tank

valve. Reclose the valve tightly. Whenever you are open-

ing the tank valve, do it extremely slowly to avoid damag-

ing the inner seals in the regulator.

2. Make sure the washer is seated evenly in the regulator

valve. Then attach regulator assembly to tank.

DO NOT OPEN THE TANK VALVE YET.

3. Insert the shorter extension tube into the plastic fitting on

the back of the flowmeter.

4. Take the other end of the extension tube and insert it onto

the “T” fitting as shown.

DISTRIBUTION RING

The distribution ring is designed to be suspended above the

plants in a circular pattern.

1. First screw the eyelets in according to the diagram.

2. Then thread the tubing through them in a circular pattern

over your growing area.

3. Connect the return end to the other side of the “T” fitting.

CO2 is heavier than air and will spread downward from the distri-

bution points. Make sure the distribution tubing is secured and

does not interfere with your lighting or light movement systems.

ADJUSTING THE REGULATOR

Once the system is securely attached and set up, your regulator

can be adjusted.

1. Plug your solenoid cord into the timer and rotate the dial

until the tabs are in an “ON” position.

2. Very, very slowly open the tank valve until it is fully open.

3. Now, using a screwdriver and a crescent wrench adjust the

PSI gauge so it reads 30 PSI.

4. Tighten the locknut.

5. Unplug the solenoid valve.

SETTING THE PROGRAMMABLE TIMER Set your timer to go on continuously for 45 minutes each day when your lights turn on. This time period will bring your room level close to the desired range. After this period, set the timer to go off for 15 minutes, then on for 15 minutes. Repeat this on/off cycle throughout the lighted period until 1 hour before the lights turn off. DETERMINING A FLOW RATE This is the basic formula for determining flow meter settings: cubic ft. of growing area x .
