CO2 Reactor Set

Product Information: Colombo CO2 Reactor Set

The Colombo CO2 reactor set is designed to produce pure CO2 from a chemical reaction. The set includes a pressure regulator, pressure gauge, pressure relief valve, hose connector, bubble counter, bubble counter base, solenoid, adjustment knob, cable connector, stainless steel cylinder, moisture filter, diffuser, hose, hose clamp with suction cups, non-return valve, and cylinder base. The set is available in the UK and NL versions.

When the chemical reaction takes place in the cylinder, the CO2 gas is slowly and constantly released through a pressure regulator. The gas flow can be precisely adjusted with the adjustment knob and integrated bubble counter. The gas flow can be stopped at night with the solenoid which is included in the set.

Product Usage Instructions

Before using the Colombo CO2 reactor set, read the user manual carefully and make sure you have all the components listed in the content section.

First, connect the stainless steel cylinder to the pressure regulator using the hose connector.
Next, attach the pressure gauge and pressure relief valve to the pressure regulator.
Connect the bubble counter base to the pressure regulator using the hose connector.
Attach the bubble counter to the bubble counter base.
Connect the solenoid to the cable connector on the pressure regulator.
Attach the adjustment knob to the pressure regulator.
Connect the diffusor to the hose and attach it to the cylinder base using the hose clamp with suction cups.
Connect the non-return valve to the hose and attach it to the diffusor.
Attach the moisture filter to the non-return valve.
Connect the hose to the moisture filter and attach it to the bubble counter.
Place the cylinder on the cylinder base and secure it using the press ring.

Once all the components are connected, follow these steps to use the Colombo CO2 reactor set:

Fill the stainless steel cylinder with water and add the provided chemicals according to the instructions in the user manual.
Wait for the chemical reaction to take place in the cylinder.
Turn on the solenoid to start releasing CO2 gas through the pressure regulator.
Adjust the gas flow using the adjustment knob and bubble counter to achieve the desired CO2 level in your aquarium.
Turn off the solenoid at night to stop the gas flow.

Note: It is important to regularly check the pressure gauge and adjust the gas flow as needed. Also, make sure to replace the chemicals in the cylinder as instructed in the user manual.

CO2 reactor manual

The Colombo CO2 reactor set makes pure CO2 from a chemical reaction. After the chemical reaction has taken place in the cylinder the CO2 gas is slowly and constantly released through a pressure regulator. The gas flow can be adjusted precisely with the adjustment knob and integrated bubble counter. The gas flow can be stopped at night with the solenoid which is included in the set.

Warnings

Do not add more water or components as indicated in the instructions.
• Do not remove pressure regulator when cylinder is under pressure.
• Do not shake bottle or hold upside down. The bottle must be upright when in use.
• Always keep the thread of the cylinder clean and avoid the solenoid making contact with water.
• The chemical reaction in the reactor produces CO2. As CO2 is heavier than air and has a suffocating effect, prevent breathing in the gas.
• Keep out of the reach of children. This set is clearly not to be used by children (<18 years) or persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge. This set is not a toy, so unsuitable for children to use!
• Do not throw the bottle and do not expose to temperatures over 50°C!
• Store the container in a well-ventilated room, not in a cellar.
• Transport bottles always completely empty!
• Check every 90 days for corrosion by visual inspection of the interior. Upon signs of corrosion, stop the use of the product.

Intended Use:

• The Colombo CO2-reactor is intended to be used only by adults of 18 years or older.
• This set is only to be used with original Colombo parts. Applying other parts or chemicals can lead to potentially dangerous situations.
• It is important to add only one sachet of Colombo CO2 reactor refills component A and one sachet component B.
• This set is only to be used for supplying CO2 gas to ornamental freshwater tanks. Other applications are not allowed and safe usage cannot be guaranteed.
• This set in only intended for indoor use under ambient temperatures (15-35°C)
• This set in only intended for private use and not for commercial use.

Preparation

Remove the label from the regulator and mount the moisture filter in the pressure regulator.
Fit the hose to the bubble counter, the other side of the hose is connected to the diffusor. The hose can be fixed with the clamps using the suction cups included in the set.
Position the diffusor as deep as possible to maximize the contact time between the CO2 gas and the water which improves the absorption of CO2 gas in the water.

Add 200 gram of Component A, subsequently add 200 grams of component B. Use the paper funnel to keep the thread of the cylinder clean and free of remainders.
Keep the cylinder under an angle of 45 degrees and add 300 ml of water in one go. Immediately screw on the pressure regulator. Adding the water slowly can affect the chemical reaction and cause problems.
Mount the pressure regulator turning it clockwise, apply enough force by hand only to close it properly. It can be more convenient to hold the regulator and rotate the cylinder. Ensure the adjustment knob is fully closed.
Add water to the bubble counter and close the cap. Push the bubble counter in the fast-fit connector. By pressing the ring marked with a*, the bubble counter can be removed again.
The system is ready for use when the pressure gauge indicates at least 10 bar of pressure. The pressure will increase until app. 22 bar when the chemical reaction is complete. The solenoid can be activated to connect the cable connectors.
When the solenoid is connected to the mains it will open, a red lamp indicates the solenoid is opened. Use the bubble counter to determine the flow speed of the CO2 gas.

Refill the system

Check if the pressure in the system is zero, if needed release the remainder of the gas by fully opening the adjustment knob.
Switch off the solenoid by disconnecting the cable connectors.
Remove the solenoid. The solenoid is relatively fragile so disconnect with care. Disconnect the bubble counter by pressing the plastic ring on the fast-fit connector. Disconnecting the bubble counter without pressing the ring causes damage not covered by warranty.
Remove the pressure regulator by turning it anticlockwise. Prevent the accumulation of powder on the thread by cleaning the thread on the cylinder, Close the adjustment knob on the pressure regulator.
Continue with the instructions under commissioning.

Maintenance and spare parts

The filter media in the moisture filter can be dried. An additional filter is included in the set, you can use this while the other filter is drying.
A spare fast-fit connector for the bubble counter is included. When required the fast-fit connector can be replaced, screw it on or off with the Allen wrench included in the set.
The O-ring in the adjustment knob can be replaced. Turn the adjustment knob anticlockwise until it releases from the housing to access the O-ring.

Use the optional Colombo CO2 indicator to continuously monitor the CO2 concentration of the aquarium water. The supply of CO2 must be disconnected at night because plants do not absorb CO2 when it is dark. The supply of CO2 can be stopped automatically by connecting the solenoid to a domestic timer.

The green O-ring on the pressure regulator is included as a spare part, when required it can be replaced.

Only use the Colombo CO2 reactor refill for your CO2 reactor. The Colombo CO2 reactor refill contains the correct raw materials of premium quality, ensuring the correct results in a safe way.

When the safety valve has become active or when it is dirty, disassemble the valve and clean it properly. Assemble the valve and see to it that the plain of the nut and the valve body are levelled as indicated in the drawing.

Frequently asked questions

Why is the pressure lower than 22 bar after the chemical reaction has taken place?
Maximum pressure is achieved 24 hours after the chemical reaction has taken place. The pressure regulator is not fitted quickly enough after the water has been added.
The pressure is normal, why I don’t see bubbles in the bubble counter?
Check if the red lamp burns on the solenoid, when the lamp is on the solenoid is open. Check if the bubble counter is filled with water
The gas is still flowing after the solenoid is closed.
CO2 gas will still be released from the diffusor, this will stop after some time.
