Connect black/red power input wire to indoor unit power supply terminal (S1, S2). Determine the best location for the DPLS2 Control Box (above the drain pan and outside of the main airflow): Using the double-sided adhesive pad, mount the Control Box in a location inside the indoor unit that will allow clearance for the cover to be reassembled (Fig 6).
Disconnect indoor unit power before proceeding to the next step. Determine the best location for the DPLS2 Micro Sensor. Make sure that power has been disconnected. Find the drain pan below the coil in the indoor unit. It is located directly below the aluminum tins of the coil and is slightly wider than the coil depending on the style of indoor unit.
