Spacer MOUNTING INSTRUCTIONS This unit is suitable for mounting in many different locations such as in a cabinet, control panel, walls, or in a standard mounting plate. The spacers are to be used to insulate the brass or stainless steel threaded portion of the sensor from any drafts or temperature changes in the wall as well as to mount the sensor into the wall. Board or Panel Mounting using the 3/8” Hex Nut or 1” or 2” Delrin Spacer 1. First drill a 3/8” hole in the board or panel and insert the button sensor (2) wires through the hole and thread the hex nut or 1” or 2” spacer onto the button sensor until tight. If the plate or panel is relatively thin, similar to a one gang junction box cover be sure to use the 1” or 2” Delrin spacer depending on the thickness of the box or enclosure. The Delrin spacer will insulate the sensor from any drafts inside the wall. A small piece of foam or insulation may be inserted in the bottom of the Delrin spacer to better insulate the sensor if necessary. Drywall Mounting using the 1” or 2” Delrin Spacer 1. First drill a 5/8” hole in the drywall. Next insert the button sensor (2) wires through the top of 1” or 2” Delrin spacer. Now thread the 1” or 2” Delrin spacer onto the back of the button sensor. Now make all of the wire connections using either crimp on connectors or wire nuts. A small piece of foam or insulation may be inserted into the bottom of the 1” or 2”Delrin spacer to better insulate the sensor if necessary. Next insert the button sensor assembly into the wall until it is flush to the wall as shown in Figure 1 below. You may need to gently tap the button sensor assembly with a hammer for it to go into the drywall.
