Ensure your CO2 cylinder is upright and securely placed.
Verify that the regulator's fitting matches your CO2 cylinder valve.
Align the regulator's inlet nut with the CO2 cylinder valve.
Hand-tighten the nut-hand-wheel firmly onto the cylinder valve. No tools are required for this step due to the patented tool-free design.
Once securely attached, perform a
If no leaks are detected, connect your 8mm EVABarrier gas line to the 8mm duotight ball valve outlet
The regulator features an integrated 8mm duotight push-in connection. Simply push your 8mm tubing firmly into the connection point until it seats securely.
Ensure your CO2 cylinder is upright and securely placed.
Verify that the regulator's fitting matches your CO2 cylinder valve.
Align the regulator's inlet nut with the CO2 cylinder valve.
Using a spanner or wrench, tighten the inlet nut firmly onto the cylinder valve.
MK4 Regulators include a KL06880 duotight – 8mm (5/16”) Female x FFL Female Thread. Thread this onto the MFL outlet thread of the MK4 regulator. Do not overtighten as this can crack the duotight fitting. For a detailed guide to correct attachment, refer .
Once correctly attached, simply push your 8mm tubing firmly into the connection point until it seats securely.
With the regulator attached to the CO2 cylinder and the cylinder valve open, the high-pressure gauge will show the cylinder's remaining pressure. The high-pressure gauge is the gauge on the left of the adjustment knob.
The low-pressure gauge indicates the output pressure. The low-pressure gauge is the gauge on the right of the adjustment knob.
MK5 only - open the integrated ball valve to allow pressure to flow.
This regulator is equipped with a 65psi Green PRV. This safety feature will release pressure if it exceeds 65psi, preventing damage to your equipment. Do not tamper with or obstruct the PRV.
If gas is venting from the PRV this indicates the pressure in the system is higher than the PRV rated pressure. Turn the CO2 cylinder valve off. Turn the Adjustment Knob anti-clockwise so that less pressure is let into the system
Pressure Relief Valves are colour coded. This unit comes with a
or can be purchased separately
Wipe the exterior of the regulator with a damp cloth. Do not use abrasive cleaners or solvents.
The MK5 regulator is designed for easy self-servicing. If contaminants enter the regulator or if pressure creep occurs, you can clean the internals:
Ensure the CO2 cylinder valve is closed and all pressure is relieved from the system.
Carefully detach the regulator from the CO2 cylinder.
Locate the M8 Hex/Allen key head on the back plate.
Use an M8 Hex/Allen key to undo this area and access the internal components. The Adjustment Knob spindle is also an integrated M8 Hex Key.
KL30670 | KL07429 | KL10870 | KL07443 | KL07436 | Leak & Pressure Testing
If there is a leak in the system or you suspect that the regulator is leaking, the best way to confirm this is a Pressure Decay Test.
If there are any leaks this can result in the CO2 cylinder becoming empty in a short period.
Initial pressure testing can be performed in two different ways. If leaks are detected an Isolation Test can help determine the location of the leak.
Connect the regulator a CO2 cylinder that definitely has pressure - this can be confirmed by weight.
Set the pressure on the CO2 regulator to 50psi, or at least 15psi less than the rated pressure of the installed PRV if using a different rated PRV.
Once pressurised, turn the valve handle on the CO2 cylinder clockwise until the valve is turned off completely.
Wait for at least two hours then check the pressure reading on the right hand (low-pressure) gauge of the regulator.
If the pressure reading has not changed (so is still reading ~50psi) then there are no leaks in the system.
If the pressure has dropped a noticeable amount then it is very likely there is a leak in the system.
If leaks are detected then proceed to a to locate the leask
that definitely has pressure - this can be confirmed by weight.
(MK5 Regulator) Shut the ball valve to prevent gas escaping from the regulator
(MK4 Regulator) Insert a short length of 8mm EVABarrier terminated with a , or plug the KL06880 FFL fitting with an .
If there is a leak in the system, but the regulator is not leaking as determined by a . If any CO2 leaks are detected, if can be helpful to perform an Isolation Test to determine where the leak is in the system - typically a kegging system (kegerator or glycol system)
Attach all disconnects to an empty keg. If there is liquid in the keg this will give a poor reading as CO2 will become absorbed into solution
Set the pressure on the CO2 regulator to at least 20psi. Wait for the empty keg to fill with CO2 to 20psi to ensure the system is properly pressurised
Once the system is pressurised, isolate each part of the system.
Once securely attached, perform a Pressure Decay Test
If no leaks are detected, connect your 8mm EVABarrier gas line to the 8mm duotight ball valve outlet
Make small adjustments and observe the low-pressure gauge until the desired pressure is reached. The time the system takes to acheive the desired pressure will vary depending largely on the volume to be pressurised.
Remove the washer and Seat Cap.
Clean any contaminants from the internal parts.
Inspect the seat cap assembly (made of ultra-high molecular polyethylene) for wear or damage.
Reassemble carefully, ensuring all seals are correctly seated.
Using a soapy water solution (washing up liquid and water is perfect for this) in a spry bottle or simply dabbed on, check for leaks at all connections. The soapy water spray will slowly bubble if there are any leaks.
Check the joins for the high and the low-pressure gauages, the join for the outlet and inlet of the regulator and (MK4 only) the FFL duotight fitting as these can be cracked if over-tightened.
IMPORTANT: Do not spray any duotight fittings with StellarSan or phosphoric acid solution to perform a leak test.
Turn valve of CO2 cylinder fully off.
Fully unwind the (anti clockwise) the regulator knob
Remove Gas Disconnect from the keg
(If using) Remove Gas Disconnect from gas inlet of kegerator
(If possible) Weigh the CO2 cylinder
Wait at least 12 hours
After at least 12 hours, if there is a leak in the system we can determine roughly where the leak is after isolating
If the weight of the CO2 cylinder has gone down noticeably, the cylinder possibly has a leak
If the pressure on the regulator has gone down, the regulator, gas line or fittings may have a leak
Test the keg(s) by pulling the PRV. If no CO2 is released then the keg may have a leak.
Once the general location of the leak has been determined by isolation testing, perform a in order to locate the leak precisely.
NOTE: It is safe to submerge duotight fittings and EVABarrier in water when locating leaks. Regulators cannot be safely immersed

Pressure creep is caused by contaminants of some kind in the diaphragm of the regulator.
A common reason for pressure creep is if liquid is inadvertently introduced into the gas line. The liquid will then enter the regulator diaphragm and cause pressure creep.
Pressure creep is quite easy to diagnose.
If the adjustment knob of the regulator is would out completely (so either removed from the spindle or wound as far anti-clockwise as possible) but the low-pressure gauge of the regulator still increases in pressure, this is 'pressure creep'.
Typically the pressure will creep up quite quickly until the PRV starts to release. if not corrected, it is quite easy to lost an entire cylinder of gas as a result of pressure creep. it can also lead to over carbonated beverages in the keg.
Pressure creep is both easy to identify and correspondingly easy to fix.
To correct pressure creep, the diaphragm will need to be replaced (MK4 regulator models) or the seat cap assembly may need to be cleaned or the diaphragm replaced (MK5 regulators).
KegLand MK4 and MK5 regulators are made with a fully encapsulated seat and seat cap design. This design makes it easier to service the regulator and also further reduces the chance of pressure creep. In addition, the MK5 regulator has a check valve built into the gas outlet ball valve
Even with excellent regulator design and several preventative measures it is still possible for pressure creep to occur and this manual has been written to describe how to resolve this issue.
The process is different depending on the model of regulator.
.
Due to their unique design, MK5 regulators generally require .
The correct diaphragm for all MK4 Regulators is KL15646
Using a large wrench or spanner, remove the bonnet (standard thread, so unscrews anti-clockwise)
Once the bonnet has been removed you will seat the seat cap assembly. Carefully remove the button from the middle of the assembly
Due to their unique, modern design, unlike most regulators on the market the MK5 Regulator diaphragm does not generally require replacement in the event of preessure creep. It can be removed and cleaned instead. In the event that it has sustained damage it can be replaced quite inexpensively however. The procedure is broadly similar.
For a video guide to maintaining a MK5 diaphragm in the event of pressure creep please see below.
In the event that the seat cap assembly needs to be replaced they can be purchased here: KL30663
Insert the new seat and seat cap assembly making sure that all surfaces and parts are extremely clean. Contamination in any of these components might cause the problem to reoccur.
Once the new seat and seat cap assembly is installed re-insert this back into the regulator body and tighten with a 16mm socket. Ensure the button is installed in the new Seat Cap assembly (refer Step 2)
Replace the bonnet by tightening this clockwise onto the regulator body. If the diaphragm and spring assembly needs replacing or came out of the bonnet during removal refer to the below image for correct installation
Perform a to ensure that the diaphragm replacement was sucessful
