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. To achieve a satisfactory seal, it is recommended that a torque of
3Nm is applied to the bolts used for holding down the Light Head to the Solar Base and that only the
supplied bolts are used.
Applying a higher Torque setting is not recommended and may void warranty. If in doubt, please
contact your local Sealite representative.
The replacement of a solar panel should only be performed by a confident technician.
Sealite cannot guarantee the chassis will remain waterproof, if service is not performed by Sealite
staff. To test for any leaks remove the gore vent and pressurise the assembled Light to 1.5psi.
