Possible Displays During Sampling
Flow or Battery Fault Shutdown - If the pump is unable to
compensate due to excessive back pressure or a low battery
condition exists, the sampler will shut down and timing functions
will pause. Either a battery-shaped icon or a fl ow fault icon
(

) will display on the LCD depending on the cause of the
shutdown. Upon fl ow fault, the pump will attempt to restart up
to 5 times. To restart from fl ow fault, correct the blockage and
press the on/off button twice. Elapsed time display will reset
to 0 when pump is restarted. If the battery icon is displayed,
recharge the battery before sampling.
Displayed Elapsed Run Time - Elapsed run time is displayed
continuously on the LCD. For elapsed times after 999 minutes,
the display still shows elapsed time, but alternates displaying
the first two digits of the elapsed time and the last three
digits. For example, a pump that has run for 1,440 minutes would
display fi rst “01” and then “440.” The display maximum is
99 999, which is 99,999 minutes.
Sampling with Impingers
Place an in-line trap between
the pump and the impinger. The
impinger and trap can be mounted
to the sampler using the accessory
mounting screws (Figure 1, #8) or
placed in a holster at the worker’s
waist.
Impinger sampling requires an
in-line trap (SKC Cat. No. 225-22 or
225-22-01) to prevent fumes from
accidentally being drawn into the
sampler. Single or dual impinger/
trap holders (SKC Cat. No. 225-20-
01 or 225-20-02) may be mounted
directly to the face of the sampler
using the accessory mounting
screws.
Failure to use an appropriate in-line trap during impinger
sampling voids any warranty.
Protect sample pump from weather when in use outdoors.
Use of any device other than the approved battery pack to
power the pump voids the UL Listing for intrinsic safety
and any warranty.
