CO2 Generation (Propane) - Step by Step Instructions

Want to add CO2 using liquid propane? Here's how you do it using a Pro-Leaf CO2 Generator and Controller.

Before starting, make sure you've got:

• 4kW: 90m2 coverage
• 10kW: 220m2 coverage

Use the Pro-Leaf Controller to control your CO2 output (from 400ppm - 2000ppm).

Propane is available in most petrol stations or garages. You normally get a hose and regulator with your propane bottle. You'll need:

• 1/2 bar regulator (4kW Pro-Leaf Generator)
• 1 bar regulator (10kW Pro-Leaf Generator)

To connect everything together, you're also going to need:

• Pipe cutters
• Spanner
• Snub-nose pliers
• Leak detection fluid
• Hose clamp / gas hose clip
• 2 Pin to 3 Pin Plug Adaptor

Here's how to put everything together.

Find the correct threaded end of the hose

Tighten it to the generator, using a spanner.

Cut the opposite end of the hose to remove the euro thread.

Soften the hose in warm water.

Thread a pipe grip onto the hose, then push the pipe over the barb of the regulator.

Close the pipe grip using the snub-nose pliers - make sure the clamp sits between the two barbs.

Remove the safety cap on the propane bottle and locate the thread on the regulator.

Insert the regulator into the propane bottle and tighten with a spanner.

Spray the propane bottle connection with leak detection fluid.

Spray the generator connection with leak detection fluid.

Open the brass valve on the top of the propane bottle to check for leaks.

Plug one end of your controller's power lead into the Plug Adaptor then plug the adaptor into your mains supply.

Spray the generator connection with leak detection fluid.

Plug your generator's power pack into the controller

Connect the other end of the generator's power pack into the generator.
