Site Considerations

Description

To protect the Maxum II from the elements, it should be located in an analyzer house or a similar

protected enclosure; see Figure 1-1. The air temperature around the analyzer should be maintained

between 0°F (-18°C) and 122°F (50°C). An installation drawing package will be sent out early in the

project to document the application specific information for each Maxum II needed for site preparation.

Final documentation will be shipped with the unit.

Location

The Maxum II is manufactured and tagged for a specific hazardous area classification. The unit must be

installed in an area that is suitable for this area classification.

WARNING The unit is tagged with a T-rating which quantifies the maximum surface

temperature that may occur in the instrument. The user must ensure that no combustible gas

concentrations will be present, whether on a continual or occasional basis, which has an

ignition temperature below the T-rating of the unit.

The analyzer house should be located as close as possible to where the sample is to be obtained to

minimize the sample transit time. It is preferable that this distance be less than 100 feet (30 m).

The analyzer house must be large enough to allow ample access for installing, operating, and

maintaining the analyzer. The concrete slab for the analyzer house should be large enough to

accommodate gas cylinders located on the outside. Make sure a cylinder rack or chain guard is provided

to secure the cylinders.

Space inside for the analyzer must be at least 90” high by 50” wide by 40” deep (229 cm high by 127 cm

wide by 102 cm deep.) The height may be somewhat less if there is no sampling system cabinet or panel

beneath the analyzer. Refer to Maxum II Outline Drawing on page

12.
