Solar Panel Replacement (SLC310 & SLC410 Models)
The SLC310 and SLC410 are built around an internal aluminium chassis. The solar panels can be 
user-replaced in the unlikely event that one is broken or damaged during the product’s life.
Follow the steps below or contact support@sealite.com for more details.
1.  Remove 4 x M6 x 20 socket head cap screws and 4 x M6 nylon 
washers and disconnect the light head from the chassis
2.  Remove the 2 x M4 x 20 socket head cap screws, 2 x M4 spring 
washers and 2 x M4 penny washers. Remove the upper battery 
bracket containing regulator
3.  Disconnect the battery 
4.  Remove 4 x M6 x 35 socket head cap screws, to remove the top 
casting from the chassis.
Note: 
Be careful not to damage the o-rings on each of these screws. If 
replacements are required please use standard 6x1.0mm o-ring.
5.  Slide the rubber corner out of the chassis, it may be necessary to 
lubricate the edges of the solar panels with grease or oil based 
lubricant if this is difcult to remove.
6.  Unscrew the affected panel wires from the regulator and remove the 
solar panel from the chassis.
7.  Clean any silicon off the chassis from the solar panel junction box 
hole and add a new seal to ensure the solar panel is watertight when 
assembled.
8.  Repeat the process in the reverse order to replace a new panel.
Note:
Make sure the O-rings on the top casting and 4 x M6 x 35 socket head 
cap screws are coated in silicon grease before re-assembling. 
The replacement of a solar panel should only be performed by a condent technician.
Sealite cannot guarantee the chassis will remain waterproof, if it not performed by Sealite staff.
To test for any leaks remove the gore vent and pressurise the assembled Light to 1.5psi.
