• COMPONENTS
• See Figures 1.1 (GilAir-3) and 1.2 (GilAir-5)
• All Models
(1) On/Off switch
(2) Flow Adjustment (requires slotted
screwdriver)
(3) Rechargeable Battery Pack
(4) Internal/External Vent Control
Use a flat-head screwdriver to adjust the internal/
external vent. The
open circle
position will vent
the pump discharge external to the sampler case
(recommended for moist or corrosive sampling
environments). The
closed circle
will vent
internally (recommended for dust laden
environments).
(5) Battery Charge Indicator. Lights up when the
pump is turned on and the battery pack is fully
charged. The indicator will normally turn off after
the pump runs for a short period of time.
(6) Flow Fault Indicator. Lights up if pump is unable
to maintain flow rate within
±
5% of the set point.
Occurs if pump is operated outside its specified
performance ranges, or if battery pack has
insufficient charge.
After about 30 seconds of continuous operation
under fault conditions, the pump will stop.
For Clock and Program models, shutdown under
fault conditions preserves the run time in the
display.
