5 Maintenance
WARNING!
• Do not use the device, sample line, or probe unless the pump alarm activates 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. If a sample line or probe is installed and the pump alarm does not activate, remove the line or probe and
repeat the test. This will provide information on where the blockage is located.
Failure to follow these warnings can result in serious personal injury or death.
Never let the end of the sampling line touch or go under any liquid surface. If liquid is drawn into the device, readings will be
inaccurate and device could be damaged. We recommend the use of an MSA sample probe containing a special
membrane filter, permeable to gas but impermeable to water, to prevent such an occurrence.
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
• Correct any flow blockage.
• Press the ▲ button.
○ The Pump will now restart.
