Disconnect power, remove junction box cover, place the SWITCH in knockout hole and fasten with locknut. 

Wire according to the diagram in right hand.

Do not install the switch with the Photocell facing artificial or reflected light. This will cause the unit to cycle on and off at night. 

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.
