Nano CO2 Regulator with Adjustable Pressure

Know Your Regulator

Single Stage CO2 Regulator layout
A: Mains cable.
B: Solenoid valve. Plug into a timer plug or pH controller to only dose CO2 at specified times and durations.
C: Needle valve adjuster; varies the CO2 dose. Turn anticlockwise to increase flow, clockwise to decrease flow.
D: Needle valve output (push-fit).
E: Pressure adjuster knob (clockwise increase pressure, anticlockwise decrease pressure).
F: Working output pressure gauge.
G: Screw CO2 cartridge into base of regulator.

Step-by-Step

Tighten dual stage regulator to CO2 cylinder
Step 1) Set the output pressure to minimum by turning the pressure adjuster knob fully anticlockwise.

Step 2) Close the needle valve by turning fully clockwise.

Step 3) Screw CO2 cartridge into the regulator. You may feel some resistance as the pin inside the regulator pierces the top of the CO2 cartridge to release the gas. Once the cartridge is screwed in, it should not be removed until all gas has been used.
Apply o-rings to CO2 cartridge
Step 4) Add O-rings to the CO2 cartridge to ensure snug fit in the base/holder.
Position the CO2 cartridge in the base/holder
Step 5) Position the CO2 cartridge in the base/holder. The base has a sticky pad underneath, which can be used to provide additional support if required.
Switch the solenoid on
Step 6) Plug the solenoid into mains plug and switch on.
Open flow of gas from CO2 cylinder
Step 7) Turn the pressure adjuster clockwise until the pressure gauge reads 0.3 MPa (which is 3 bar or approximately 40 PSI). This is a good starting point for most CO2 diffusers. It can be increased if necessary.

Step 8) First ensure you have a straight and clean cut at the end of the tubing, then push firmly into the Pisco valve until it won't insert any further. No additional action is needed; the Pisco valve will securely hold the tubing in place.

Step 9) With the bubble counter attached, turn the needle valve anticlockwise to achieve the desired bubble rate. 1 bubble per second is suitable for a 150L aquarium - adjust your dosing in accordance to this, i.e. 1 bubble every 2 seconds for 75L aquarium.

Step 10) To remove the tubing from the Pisco valve push down on the collar at the top of the valve and simultaneously gently pull the tubing from the valve.


Check for Leaks

It is recommend that each time you reconnect the regulator to the CO2 supply that you check for leaks. Identifying a leak from the outset is a much more desirable result than discovering there is a leak only when a substantial amount (or all) of your CO2 cylinder has leaked.

The easiest way to check for leaks is to cover all of the joins with soap suds, and look for any sign of bubbling, and also listen for a 'hissing' sound. If your regulator has a solenoid it is recommend you switch the electricity supply off prior to applying soap suds. Please also try to only use the soap suds themselves, and as little water as possible.
