Operator’s Guide
5. Follow the compressor’s instruction manual to modulate the outlet pressure between 5.0 and
8.0 bar (72.5 and 116 psig).
6. Connect the air compressor’s power cord to a suitable electrical outlet.
7. Turn the air compressor’s ON/OFF switch to ON or AUTO.
8. Allow the air pressure in the receiver to build to at least 5.0 bar (72.5 psig).
Note:
With the air compressor in auto mode, the motor will automatically stop when the
pressure reaches a preset maximum and will restart when the pressure drops below a preset
minimum. You can monitor the pressure in the receiver via the receiver pressure gauge.
The minimum pressure required for use with the Pressure Elution Station is 5.0 bar. The air
compressor should have a sufficient flow rate to maintain pressure above 5.0 bar during use.
9. To increase or decrease the outlet pressure, turn the pressure regulator’s adjustment
according to the manufacturer’s instructions.
10. When you have attached the quick-connect fittings to the Pressure Elution Station and there is
pressure, turn the lockable air inlet valve counterclockwise to the ON (SUP) position. The air
supply is now ready for use with the Pressure Elution Station.
Note:
If the pressure from the air supply falls below 5.0 bar (72.5 psig), there will be
insufficient pressure to complete an elution cycle and a
Low Pressure
error message will be
displayed. When processing multiple samples, be sure to monitor the pressure.
Checking the pressure regulator setting
With pressure supplied to the Pressure Elution Station and the lockable air inlet valve in the ON
position, the high-pressure gauge should read approximately 5.0 bar (72.5 psig), while the
low-pressure gauge should read approximately 0.38 bar (5.5 psig).
If the gauge readings are not correct, contact IDEXX Technical Service for assistance.
Note:
The low-pressure regulator, a precision-regulator located within the Pressure Elution Station,
will always release a small amount of air; a slight hissing sound is normal.
