Pump

When using the pump module, attach it and the pump accessories prior
to activating the detector.
The pump module can be used independently to measure gas or it can
be used with the sample probe to test for gases in confined spaces. To
measure gas using the sample probe, refer to
If the pump module is installed on the detector, the
following three things must occur during start-up. If any
one of the conditions below does not occur, discontinue
use of the detector and contact BW Technologies by
Honeywell immediately.
• The detector prompts for a pump test during start-up
• The pump module passes the pump test at start-up when
the pump inlet or sample chain inlet is blocked
• The J icon displays on the LCD
To ensure accurate gas detection, the sensors must be
calibrated immediately when the pump module is
replaced by the diffusion cap and vice versa.
When using the sample probe at -10°C to +0°C (14°F to
32°F), keep the sample probe in your hand.

A demand flow regulator must be used to manually
calibrate the GasAlertMicro 5/PID/IR detector when the
pump module is installed.
The calibration cap is designed for use with the diffusion
cap only. It cannot be used with the pump module.

Identifying the Pump

Sampling.
There are two generations of pump. The best way to differentiate the
Generation 2 pump from the Generation 1 pump is the inline filter that is
visible on the Generation 2 pump on the left-hand side.
Each model of pump has different operating specifications. Refer to
