Push the photocontroller on and twist it clockwise to lock it into the receptacle. 

Install the photocontroller with the Photocell facing the NORTH direction as indicated on the top of the photocontroller.

Initial Testing

It is normal for the SWITCH to take several minutes to turn off when first installed.

To test “turn on” during daytime, cover its eye with sliding the metal strip mounted.

Do not cover with finger because light traveling through fingers may be great enough to keep the switch open.

Test will take approximately 2 minutes.
