SKC Limited EPAM-5000 - Manual (Page 78)

Flow Rate Not Achievable
Perform the following checks if the flow rate of 4 LPM is not attainable.
• Air flow meter must be vertical to ensure accurate measurements.
• Air intake tubing is attached to filter cassette.
• Air may be leaking from the sensor covers on the front and right side of
optical sensor of the monitor. This can be tested quickly by operating the
unit (Chapter 3 page 3 -9) and placing your palm or thumb over the inlet
where the sample stream enters the unit. If this does not result in a
noticeable strain on the pump, it is likely that leaks exist around the sensor
covers or cassette holder. Remove the sensor covers and ensure the proper
cover placement front cover must be placed on front of sensor this cover
can be identified by the circular pattern on the gasket material of the cover
itself and reinstall them tightly. Cassette holder must have the white filter
holder ring installed and holder must be screwed on tightly to avoid air
leaks.
