1. Do not face the photocell into the midday sun. If installed on the south side of a building, face east or west or point the photo control down toward the ground. The best direction to face the photo control is north.
2. Do not face the photocell where it can see artificial light.
Light from windows, signs, street lights, etc., will cause the photo control not to switch on. The photo control should not be positioned so that it sees the light it is controlling (or reflected light). These conditions will cause the light to cycle on and off.
3. When you are testing the photo control, be sure to turn on the power (load will come on) and wait up to 5 minutes for photocell to switch load off. For further testing cover the photo control completely with black tape or another dark material to simulate night conditions. If you can’t cover the control with tape, try covering the photo control with the shipping carton to simulate night conditions.

NOTE: Mount unit so that top of case is in an upright position.

TESTING: Make sure circuit is clear of shorts before applying

power. Cover “EYE” with hand to activate unit. Repeat several

times. Under extremely bright light it may be necessary to place

an opaque item over the entire unit to activate it. Slight buzz from

unit does not impair operation.

If this does not work, switch breaker off and wait ten minutes. Switch breaker on. The load should be on.
