Probe Filter; Warning - MSA Sirius Mode D'emploi

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 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.

PROBE FILTER

• The MSA sampling probe contains a filter to:
• block dust and dirt
• block the passage of water.
• If the probe tip is accidentally submerged in water, the filter
prevents the water from reaching the internal pump. The filter is not
designed to stop other liquids, such as gasoline or alcohols.
To Replace the Probe Filter (FIGURE 6-7):
1. Grasp the probe handle by the base and guard.
2. Push the cap section toward the other two and turn clockwise.
• The spring pushes the sections apart.
3. Grasp and spin the wand clockwise while pulling to disengage.
4. Remove the water trap filter (P/N 801582) and replace.
