Connect the adaptor and tube to the
Beer Check by twisting the Luer Lock fittings
clockwise until snug. (The tubing should be
pushed on the adaptor.)
Connect to the gas system: Read
Caution on the Back Page! The threads on
the adaptor are 7/8” - 14 threads like the
connections on a typical keg coupler. Turn off
the gas to the keg and release the handle
of the coupler. Reduce the outlet pressure
of the Secondary regulator to 5 to 10 psi.
Disconnect the gas supply from the coupler and attach to the
adaptor.
Turn on the Beer Check by touching the screen. It will open in
the CO2/N2 mode within 10 seconds. Turn on the gas to the Beer
Check.
Take a reading: The most accurate reading is when the numbers
first stop flashing for more than a few seconds.
Turn off and disconnect the Beer Check: The Beer Check will
turn itself off but you’ll increase times between battery charges if
you turn it off after you have taken a reading.
Turning the Beer Check Off: Touch “Main” and then “Off”.

Notes
The Beer Check has a rechargeable battery that is not replaceable
in the field. Remember to
keep it charged. (Baery-
shaped indicator in upper
left corner of the screen.)
The operating principles
of the Beer Check are
such that it will only be
accurate when the gases
in the mix are the only ones present. For example if you were to
sample the gas from a beer keg the gas would also contain water
vapor and alcohol vapor making the results inaccurate.
The screen which is also a touch pad works best when tapped with
a fingernail or plastic stylus.
The Beer Check will turn itself off when left untouched for 5
minutes. To turn it off manually touch the Main icon and then the
Off icon.
The Beer Check cannot be calibrated in the field. It is ideal to keep a
known, accurate calibration gas to test the unit from time to time,
ensuring the accuracy of your readings.
The Beer Check is affected by altitude, if you will be using it above
4,000 please discuss this with McDantim.
If there is more than one blend, repeat the process for a keg on the
other blend.
If you have any questions or need assistance, contact us

Caution
Never leave the adaptor connected and flowing. The gases in beer
systems, CO2 and N2 can cause a person to pass out without
warning which can be fatal. Always have another person outside
the cooler keeping track of you when working in a beer cooler. This is
true whenever working on a gas supply system.
The Beer Check is intended to work in the modes described in the
Beer Check Instructions. It will not work accurately with other gas
combinations. We suggest checking the Beer Check periodically with
a Calibration gas and having it tested once a year for accuracy.
