Maintenance

Replacing a Sensor, Pump, or Pump Filter

aWarning

To avoid personal injury, use only sensors

specifically designed for the detector. See the

section,

Replacement Parts and Accessories.

Each sensor has a high degree of resistance to common

vapors and gases. A sensor will most likely clear itself if you

remove the detector to a clean environment and wait 10 to

30 minutes. Do not expose a sensor to the vapors of

inorganic solvents (e.g., paint fumes) or organic solvents.

The

Troubleshooting section describes problems caused by

a sensor in need of calibration or replacement.

The internal pump draws air over the sensors. If the pump

stops working or the pump filter becomes clogged, the

detector activates the pump alarm. Turn off the detector

immediately.

Pump Filter

Check if the pump filter is clogged by viewing the pump filter

through the window on the back of the detector. Clean the

filter using a soft, clean brush and clean, warm water. Let the

filter dry before replacing it.

If the pump alarm activates a second time, insert a new

pump filter. If the alarm activates with the new filter in place,

contact

BW Technologies.

Replacing/Adding a Sensor

A GAMAX3-2 (2-gas: O

, LEL) or GAMAX3-3H (3-gas O

LEL, H

S) detector can be upgraded in the field to a 3 or 4-

gas unit. Install the desired H

S or Twintox (CO/H

S) sensor

(this must be done outside the potentially explosive

atmosphere). Refer to the

Sensor Enable/Disable Option

section.
