The perfect entry-level CO2 release kit for those using bottled gas. The UNIS has be designed for the ultimate in ease of use and is probably the simplest gas regulator system to set up in the world! The control panel has a total of 16 settings for a range of different room sizes, plus the regulator is pre-set so theres no need to alter the flow rate. It's ultra reliable, very competitively priced and is suitable for use in both sealed rooms as well as with conventional setups that have an extraction system in place. How To Use UNIS CO2 Kit Firstly you need to connect the regulator to the control panel with the supplied wire. Next screw the regulator to your CO2 bottle, be sure to use the washer and tighten with a spanner to ensure an air tight seal. Now choose the appropriate setting on the panel to match to your room size, plug the UNIS into a timer so it turns off at the same time as your lights do and you are ready to go! For those running an extraction fan we suggest choosing a slightly higher setting to account for the carbon dioxide that will be sucked out via the fan. It is also advisable to use CO2 tubing, especially in medium to large spaces to minimise wastage.
