OVERVIEW
Warning
- Ensure the power source meets the requirements listed in the product specifications.
- Do not operate the unit if the power cord or plug becomes damaged.
- Regulate CO2 levels within a safe range. CO2 levels above 2,500 parts per million (ppm) can cause symptoms of illness, and levels above 5,000 ppm are toxic.
- Follow local regulations for the transportation and storage of CO2. Improper handling of highly pressurized gases can lead to personal injury or property damage.
- While the regulator is operating, open or close the flow adjustment knob so the flowmeter’s ball is within the marked section of the meter. Excessive CO2 flow rates can freeze the regulator, causing permanent damage.
- Cover the regulator when using sprays or foggers to avoid damaging it. Do not expose the unit to water.
- Only use the CO2 regulator indoors.
Installation
For regulator installation, follow instructions for both connected CO2 tank
- Before connecting the regulator to the CO2 tank, install the tank on a flat surface and secure it so it cannot fall or tip over.
- Ensure the tank valve is free of debris by opening the tank valve for three to five seconds. Reclose the valve securely.
- Position the regulator so the flowmeter is fully upright. Do not hold the flowmeter when connecting the regulator. This could damage the seal at the base of the flowmeter.
- Place an O-ring washer between the valve connection and the CO2 tank valve to create a seal.
- Hand-tighten the nut on the valve connection, then use a crescent wrench to ensure the connection is secure. Do not overtighten the nut.
- Attach the provided tubing to the hose barb.
- Slowly open the tank valve to allow CO2 to flow to the regulator. Spray a soap solution on the connections to check for leaks. If bubbles appear, resecure the connections.
- Rotate the flow adjustment knob on the regulator one-half turn counterclockwise. (Skipping this step could result in damage to the unit caused by excessive pressure.)
- Plug the regulator into a timer or controller supplying 220-volt power.
- Rotate the flow adjustment knob to adjust the flow rate of CO2 through the tubing and into the growing area. The height of the ball in the flowmeter will indicate the flow rate setting in cubic feet per hour.
Timed Operation
Using a timer or controller to activate the regulator is the safest and most
efficient way to ensure the CO2 level in the growing area stays around the
recommended 1,500 ppm. The average ambient CO2 level is 400 ppm. The regulator
will typically need to add about 1,100 ppm to the air every three hours to
maintain a CO2 level of 1,500 ppm.
Use the following formula to estimate how long the regulator should be
activated to attain the desired CO2 level. The actual time required will vary
depending on environmental conditions in the growing area.
- Divide the desired increase in CO2 ppm by 1,000,000.
- Multiply the result by the dimensions of the growing space in cubic feet (length by width by height).
- Divide the result by the flow rate setting.
- Multiply the result by 60 to find the time in minutes the regulator will need to be activated.
Example: Increase the CO2 level by 1,200 ppm in a 500-cubic foot space using a flow rate of 10 cubic feet per hour.
- 1,100 + 1,000,000 = 0.0011
- 0.0011 X 500 = 0.55
- 0.55 + 10 = 0.055
- 0.055 X 60 = 3.3
The regulator should be activated for about 3.5 minutes to increase the CO2 ppm by 1,100.
