Once gas readings are displayed, plug the free end of the sampling line or probe.
- The pump motor shuts down and an alarm sounds.
- PUMP ERROR will flash on the display.
When the pump inlet, sample line or probe is blocked, the pump alarm must acti-
vate.
 Press the  button to reset the alarm and restart the pump.
If the alarm does not activate:
- Check the sample line and probe for leaks.
- Once leak is fixed, recheck pump alarm by blocking the flow.
 Press the  button to reset the alarm and restart the pump.
During operation, a pump alarm may occur when the:
- Flow system is blocked
- Pump is inoperative
- Sample lines are attached or removed.
To Clear Pump Alarm
(1) Correct any flow blockage.
(2) Press the button.
 The Pump will now restart.
Warning!
Do not use the pump, sample line, or probe unless the pump alarm acti-
vates when the flow is blocked. Lack of an alarm is an indication that a
sample may not be drawn to the sensors, which could cause inaccurate
readings.
Failure to follow the above can result in serious personal injury or death.
Never let the end of the sampling line touch or go under any liquid sur-
face. If liquid is drawn into the device, readings will be inaccurate and de-
vice could be damaged. We recommend the use of an MSA sample
probe containing a special membrane filter, permeable to gas but imper-
meable to water, to prevent such an occurrence.
