6. MAINTENANCE AND TROUBLE-SHOOTING

Should problems arise with the light fitting's operation, turn off the power for a few moments, then

recheck the operation. Check also that the lamps are fixed securely in their lamp holders. If this has

no effect, change the lamps. Check also the securing of the wires to the terminal block.

Always switch off the power before changing lamps! If the lamp has been changed while the

power is on, switch off the power for at least 30 seconds after changing the lamp.

If the PIR sencor fails to work though the power supply is on, switch off the power supply before

removing the PIR sensor from the light fitting and sending it for replacement.

7. CLEANING

The lens should be cleaned when necessary using a damp cloth. Do not use cleaning agents or

solvents as these may damage the lens surface!
