3.1 Using the ALTAIR Pump Probe
(1) Press the POWER ON/OFF button.
The audible alarm sounds.
The pump motor starts fast and then slows down as the pump speed is
automatically adjusted.
Once the pump is ready for use, the green LED flashes every
two seconds.
(2) Check the pump by blocking the free end of the sample line or probe.
The pump motor shuts down.
The audible alarm sounds.
The Flow LED turns red, indicating a flow fault.
(3) When the pump inlet, sample line, probe or pump outlet is blocked, the
pump alarm must activate. If the alarm does not activate:
Check the pump, sample line, and probe for leaks and pump outlet for
blockage.
Once the leak is fixed and/or the outlet blockage removed, recheck the
pump alarm by blocking the flow.
(4) Check the pump before each day’s use.
(5) Press POWER ON/OFF button to reset alarm and restart pump.
During operation, a pump alarm may occur when the:
- Flow system is blocked.
- Pump is inoperative.
- Sample line is attached or removed.
- Filters become clogged with excessive dirt or debris.
WARNING
Do not use the pump, sample line, or probe unless the pump alarm activates
when the flow is blocked. Lack of an alarm is an indication that the 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 allow the end of the sample line to touch or go under any liquid surface.
If liquid is drawn into the device, readings will be inaccurate and the device
could be damaged.
