Compact 3-5nm+ Solar Marine Lanterns
SLC310 & SLC410 Models
Designed to be almost maintenance-free, the SL310 and SLC410 require minimal attention, though
the following maintenance and servicing information is provided to help ensure the life of your Sealite
product.
1. Cleaning Solar Panels- occasional cleaning of the solar panels may be required. Using a cloth and
warm soapy water, wipe off any foreign matter before rinsing the panels with fresh water.
2. Battery Check- inspection of batteries should be performed every three years (minimum) to ensure
that the charger, battery and ancillary electronics are functioning correctly. Using a voltage meter,
check that the battery voltage is at least 12 volts under 100mA load, and ensure all terminals are
clear of foreign matter.
3. O-Ring Check- inspect the condition of the o-ring for damage, wear or if it is brittle, and replace if
necessary. The o-ring should be a rubber texture to ensure a complete and even seal.
Replacing the Battery
The SLC310 and SLC410 have an internal battery compartment, which provides the user with the
ability to change the battery after years of operation.
1. Remove the four socket-head screws on the top lens assembly and separate the SLC310/410 lens
assembly from the body/base section.
2. Remove 2 x M4 cap screws & washers from the top of the chassis.
3. Disconnect the light head and battery via the 4Pin connector.
4. Lift the upper battery bracket out of the SLC310/410.
5. Remove the old battery from the chassis.
6. Contact Sealite if you require a battery.
7. Discard old battery in a safe manner.
8. Reconnect the new battery.
9. Place battery back inside lantern body, and position the upper battery bracket in the top of the
chassis.
10. Secure using 2 x M4 cap screws & washers.
11. Feed all wiring back inside lantern body, and make sure the o-ring is properly placed at the top of
the lantern body. Reconnect the 4 pin connector.
12. Place the top lens assembly back onto the lantern body and replace 4 socket head screws. Half
tighten all 4 socket head screws, and then fully tighten each socket head screw to ensure an even
seal.
13. To test place dark cover (towel or jacket) on top of light to activate sensor, light will come on.
Care must be taken to observe the polarity of each wire before they are connected.
To ensure waterproofing of the unit, make sure that there is an even seal.
Long Term Battery Storage
If the SLC310/410 is to be placed in storage for an extended period please follow the below
information.
The sealed lead acid batteries inside the lights must always be stored in a fully charged state.
Always make sure the ON/OFF switch is in the OFF position.
If an ON/OFF switch is not fitted please disconnect the light head from the solar unit.
All batteries will discharge over time and the rate of discharge is dependent on temperature.
If the light is being stored in temperatures greater than 40
º
C the battery will discharge faster.
Please check battery regularly and recharge if necessary.
Re-connect the light head and battery and place unit in the sun for 2-4 days
