Instruction manual

NOTE: When the instrument is in a gas alarm, the pump
alarm may not display until after the gas alarm is
cleared.

CAUTION
Never let the end of the sampling line touch or go under
any liquid surface. If liquid is sucked into the instrument,
readings will be inaccurate and the instrument could be
damaged. We recommend the use of an MSA Sample Probe
(part no. 497600, 800332, 800333, or equivalent) containing
a special membrane filter, permeable to gas but impermeable
to water, to prevent such an occurrence.
FiveStar Alarm Aspirator Assembly
The FiveStar Alarm Aspirator Assembly is an accessory for use
with FiveStar Alarms. Through simple attachment, it allows you to
change from diffusion operation to pumped operation.
• Prior to Aspirator Assembly attachment, verify FiveStar battery
contacts are clean and unobstructed.
• Inside the Aspirator Assembly, below the battery contacts, are
two raised plastic tabs which mate with two notches on the
FiveStar unit bottom, near the battery pack hold-down screw.
Battery and Aspirator Assembly contacts must meet to ensure
proper operation.

WARNING
Once the Aspirator Assembly is no longer being used for sampling,
remove it and allow the Passport unit to sample in the diffusion
mode. Otherwise, if the Aspirator Assembly is in place and the
aspirator bulb is not actively being used, atmospheric samples
will not reach the sensors; inaccurate readings may occur, which
may cause serious personal injury or death.
Use this Aspirator Assembly to sample only the following
gases. Using the Aspirator Assembly to sample other gases
may result in inaccurate readings which may cause serious
personal injury or death.
Methane Hydrogen Oxygen
Propane Butane
Carbon
Monoxide
Pentane Ethane
Hydrogen
Sulfide
