INSTALLATION
SELECTING A LOCATION
Factors such as prevailing winds, gas density, potential leak sources, air movement machinery and similar
environmental variables are important when selecting a location for any gas monitor. Even though the
GASMAX II is designed for rugged service, sensors and electronics should be protected from damage due
to environmental effects including liquid water, snow, shock, vibration and dirt.
In addition, the GASMAX display should be located such that regular maintenance and periodic sensor
replacement can be readily accomplished. While there are no industry standards for gas detector
placement, professional tools exist that can simulate leaks or spills and provide excellent guidance for
locating gas detectors throughout a facility.
MOUNTING THE GASMAX II + GDS-IR Sensor (Vertical Orientation)
Mount the GASMAX II + GDS-
I assembly using / 6” nuts and bolts through the
mounting ears located on each side of the yellow enclosure. See Drawings and
Dimensions for detailed measurements. While the GASMAX II + GDS-IR can be
mounted flush against a wall, GDS Corp recommends that the GDS-IR sensor be
located in such a way as to allow air to flow past the sensor from any direction. In
addition, space around the GDS-IR will allow a Rain Guard (p/n 3000-9005) to be
installed if necessary.
The type of gas to be detected will determine the recommended height above
ground. To detect heavy gases, such as propane or ethylene, mount the sensor
within ” to ” of the floor. o detect lighter gases
in indoor situations, mount the
sensor at eye level or near the ceiling.
To make calibration easier, GDS Corp recommends the remote sensor configuration for heavy gases. This
allows the display to be located at eye level while the sensor is located near the floor.

TO FACILITATE THE
REMOVAL AND REPLACEMENT OF THE GDS-IR SENSOR COVER AND HYDROPHOBIC FILTER AND TO ALLOW
ACCESS TO THE CALIBRATION GAS INLET NIPPLE ON THE BOTTOM OF THE SENSOR.
MOUNTING THE GASMAX II + GDS-IR Sensor
(Horizontal Orientation)
The GASMAX II + GDS-IR can also be ordered with
the sensor mounted horizontally (sensor head type
“ ”). his orientation is useful if space below the
sensor is limited or if a Rain Shield (p/n 20-0236) is to
be installed on the GDS-IR.
Fittings are both
¾” P
and wiring can enter the
sensor head from either the left or right side.
