A Components Detectors and sensors have a temperature range of 32 F 0 C to 100 F C If the HVAC system fails and temperatures within the enclosure below or exceed this temperature range damage may occur to the Use only photo sensors within the enclosure Do not mount this enclosure to a duct in which the air velocity is less than feet per minute outside temperature range in which the Weatherproof Enclosure can be must be between F 40 C and 158 F 70 C Be aware that the temperature range within the enclosure must be between F 0 C and 100 F 37.8 C which is the acceptable range for the 1 shows a three dimensional view of the Weatherproof Enclosure and duct detector sensor As shown in this figure the entire assembly consists of the following components Mounting Gaskets 631 177 631 178 and 631 179 These gaskets create a seal the holes on the rear of the enclosure and the holes on the air duct Weatherproof Enclosure This document includes a full size template that allows you to cut the four air flow tube holes see below on the air duct Air Flow Tubes Four air flow tubes two for the enclosure and two for the air duct help maintain the same air temperature within the duct detector sensor housing and weatherproof enclosure deterring condensation from building up in either the housing or Duct Detector Sensor Housing This document describes mounting the housing to the

vertical surface only The enclosure can be mounted to a rectangular duct only Do not mount the enclosure to a duct Installing the duct in the vertical position Figure 3B shown below requires a with a minimum size of 18 W by 24 H Installing the duct in the horizontal position shown below requires a duct with a minimum size of 18 H by 24 W Figure 3A indicates the preferred position in which the template and therefore the enclosure be mounted Orienting the template in this position ensures that the duct service entrance faces downward which deters water from entering the duct housing Be aware that the preferred orientation of a duct detector sensor in a weatherproof enclosure is different than the preferred orientation of a duct installed on an indoor duct The enclosure can be mounted in either the horizontal position 3A or the vertical position shown in Figure 3 below Do not mount the enclosure in the position 3C shown on the right of Figure 3 This is the Position not place this edge at top not palce this edge at top 3 Mounting the Template the and Holes the template on the duct and cut the tube holes as follows Scribe a level line on the duct Position the line on the duct at the point where the top of the will be located Align the top edge of the template with the level line scribed on the duct Use duct tape to the template to the duct at all four corners Each of the template four guide holes contains a set of cross hairs that mark the exact center the hole Use a metal cutting hole saw to cut holes in the duct as follows Use a 1 3 8 hole saw to cut the two smaller holes
