INSTALLATION

2 INSTALLATION
The Condumax II Hydrocarbon Dew-point Analyzer Sampling System gas handling
components are assembled onto a stainless steel mounting plate suitable for wall
mounting.
The indoor version Sampling System should be located in a constant temperature
controlled environment of at least +10°C (+18°F) above the highest envisaged dewpoint
temperature at a point as close to the sample gas take-off point as possible. This
will minimize sample line response time lag in a designated IEC Zone 1 and Zone 2
hazardous area and NEC Class 1, Group B (for CSA Version Sampling System).
The outdoor version Sampling System provides environmental ingress protection to IP66
and should be mounted vertically, free of any appreciable vibration, in a permanently
shaded position to prevent heating effects through sun radiation. The Sampling System
enclosure has thermostatically controlled heating (fixed set point, optional adjustable).
Enclosure cooling, using a compressed-air-driven vortex tube and adjustable thermostat,
is recommended for installation in hot climates.
