4.0 System Maintenance
Although the system is designed to be maintenance free, large performance gains can be made
with clean solar panels and lenses.
Maintenance Type
Instructions
Cleaning: Yearly
Use water and a soft sponge or cloth for cleaning and a mild, non-
abrasive cleaning agent for more stubborn residue. Rinse well.
Pressure washers should not be used (water forced up into the
louvers may soak internal components).
Note: Clean solar panels more frequently during drier months, as
they may become soiled more quickly.
Inspection: Yearly
1. Check all electrical and mechanical connectors yearly to ensure
they are clean, secure and undamaged.
2. The main battery housing has several vents and drain holes.
Ensure that they are free of debris.
3. Visual inspection – check over exterior assembly for cracks,
missing or broken hardware or other potential problems.
4.1. Troubleshooting
There are two faults that may occur with the R820 that will prevent the light from flashing:
1. Check the battery connection and the LED array connection to ensure that the
connectors are fully inserted. As the light is designed to function as soon as the battery
is plugged in, this should be fairly simple to diagnose.
2. IF SO EQUIPPED: Certain units have batteries that
utilize inline fuses. In the case of system malfunction,
open the inline fuse holder (pictured left), and check the
state of the fuse. If the interior filament is intact, the fuse
itself is functional, otherwise replace fuse with
Cooper-Bussman model ABC-4 (4-amp fuse).
If your R820 flasher still refuses to operate correctly, contact Carmanah Technologies Corp. at
877-722-8877 or contact your distributor.
