# Step description
Note! Maximum allowed overpressure is 100 mbar.
Fit a filler hose from the H
of the valves on the Test Cell. Gas from gas
cylinder must be run through an mbar pressure
regulator regulating the pressure down to less
than 1 barg.
1
Fit an exhaust hose to the other valve. Exhaust
must be released to a safe area or into a suitable
ventilator system.
Dimension of the valve nozzles are 6.4 mm (1/4")
OD.
2 Open both valves on the Test Cell.
Start the filling of H
liter/minute, wait for approximate 2 minutes. For a lower gas flow filling time has to be
3 increased accordingly. For example for a flow of 1 liter/minute a filling time of 6
minutes is required. Too short filling time will result in the gas reading being lower
when performing Function test.
4 Close the gas bottle.
5 When the gas stops flowing, quickly close both valves on the Test Cell.
6 Disconnect the Test Cell from the hoses.
Note! After filling, the Test Cell will only be able to hold the gas at a reliable concentration
for a limited amount of time (few days). Replenish or refill the cell if the concentration is
suspected to have dropped.
