92. INSTALLATION2.1 Mounting the GD10P2.1.1 LocationThe detector must be mounted horizontally wired according to fig. 2.5.NOTE: The area in which the detector may be mounted must be inaccordance with the certification of the detector and in accordancewith the standards of the appropriate authority in the countryconcerned.Choice of mounting area:• The detector should be mounted where gas leakage is mostlikely to occur. To detect methane, which is lighter than air,inside an enclosed area the detector should be mounted highin the area to be protected or immediately above potentialleakage sites.• To detect gases heavier than air, e.g. propane, the detectorshould be mounted below the potential leakage site.• The detector should be mounted in a place wheremaintenance, i.e. cleaning of the optics, is easily performed.• The detector may be mounted in areas where no oxygen ispresent.• The detector may be mounted in areas with strong airflow• The detector should NOT be mounted where it could beexposed to water drenching.NOTE: The detector must always be used with the Weather Protectionor Sample Flow Housing mounted. Exception to this must bediscussed with Simrad Optronics.2.1.2 Ventilation duct or pipe mountingIf installed in a ventilation duct or pipe, the mounting arrangement andaccessories shown in Figure 2.1 and 2.2 should be used.The Duct Mounting Bracket shown in Fig. 2.2 allows the GD10P to bepositioned in the core of the airflow in wide ducts or pipes.NOTE: Avoid direct light on lens and mirror if the GD10P is mountedwithout the Weather Protection.
