COMMISSIONING THE CABINET
Check all the following points before starting to commission the workstation.
1.Switch "OFF" the cabinet at the Mains ELCB switch.
2.The gas flow has been set at the factory to 35 litres per minute.
3.Open the mixed gas pressure regulator fitted to the gasbottle sufficiently high to maintain an inlet
pressure to the cabinet of approximately 30 psi (2.0 Bar) with the gas flowing.
4.Ensure that the Gas Trap Bubble Bottle is filled up to the water level line and the gauntlets and
bungs are both fitted to the cabinet. (Page 7)
5.Hang the Indicator Pump on the hook adjacent to the electrical socket, plug the pump into the
socket.
6.Ensure that the bottom lid of the petri dish entry lock is in the closed position. Remove the top lid of
the lock and place it at an angle over the top of the lock ensuring that there is a gap for the flushing
gas to escape, as shown on page 9.
7.Check that the Atmospheric Conditioning Sachet and the Palladium Catalyst Sachet are in position
underneath the shelf. The Atmospheric Conditioning Sachet should be put in first to the rear of the
cabinet.
8.Set the humidistat to 70% R.H.
9.Switch the commissioning switch on the control panel to the ‘ON’ position by sliding the switch
locking device along the switch body.
10.Now switch on the cabinet at the E.L.C.B.
11.Gas will begin to flow into the incubator and out of the lock.
12.Leave the gas flowing for approximately 25 minutes then place the anaerobic indicator bottle in
position filled to the appropriate level with indicator solution and connect it to the pump with the
flexible tubing. (See the instructions regarding the preparation of the indicator solution on page 7)
13.If the indicator solution remains colourless the cabinet is anaerobic.
14.During thisperiod, the inside of the cabinet will mist over, but eventually this condensation will
clear. The catalyst sachet will also get quite warm.
15.Once the cabinet is anaerobic, replace the lid of the Petri dish entry lock.
16.Switch the commissioning switch back to the ‘OFF’ position. This will bring the gas leak circuit back
into operation.
17.Ensure the commissioning switch locking device prevents the commissioning switch being
accidentally switched to the ‘ON’ position
18.Now check all functions are working.
