Panel Location and Mounting
The OPM Panel is suitable for indoor use only. Table 4 lists the allowable temperature and humidity
ranges. Locate the panel at a convenient height, and allow adequate clearance for the door swing.
Mount the panel to the wall with screws or bolts. It weighs approximately 30 pounds (14 kg). Four ¼-
inch openings are provided at the corners of the panel. Panel dimensions are shown in Figure 3.
The panel is equipped with special door hinges that have a friction adjustment screw. By adjusting
this screw you can prevent the door from swinging open or closed unexpectedly.
