Installation Instructions
1. Pre-Installation Checklist
- Ensure power is OFF at the main circuit breaker.
- Confirm you have a compatible 12V low voltage landscape lighting transformer (not included).
- Gather necessary tools: shovel, wire strippers, waterproof wire connectors, level.
2. Site Preparation
- Select the desired location for your well light. Ensure adequate drainage to prevent water accumulation around the fixture.
- Dig a circular hole approximately 6-8 inches deep and 6 inches in diameter. The depth and diameter may vary based on soil conditions and desired flushness with the ground.
- For concrete applications, a sleeve or form must be prepared during concrete pouring to accommodate the fixture.
3. Wiring
- Route the low voltage cable from your transformer to the prepared hole. Leave sufficient slack for connections.
- Strip approximately 1/2 inch of insulation from the ends of the fixture's pre-wired UL listed cable and the main low voltage cable.
- Connect the fixture's wires to the low voltage cable using appropriate waterproof wire connectors (not included). Ensure a tight and secure connection.
- Verify polarity if required by your transformer or system, though most low voltage landscape lighting is non-polar.
4. Fixture Placement
- Carefully place the FG320 fixture into the prepared hole. Ensure the top of the fixture is flush with or slightly above the ground level to prevent water pooling.
- Backfill the hole with soil, gravel, or concrete, ensuring the fixture is stable and level. Compact the material around the fixture to secure it in place.
- Adjust the internal lamp housing if necessary to direct the light beam as desired.
Operating Instructions
Once the FG320 well light is properly installed and connected to a 12V low voltage transformer, operation is straightforward:
- Turn on the power to the low voltage transformer.
- The light will illuminate. If your transformer has a timer or photocell, the light will operate according to those settings.
- No direct control method is present on the fixture itself; control is managed via the connected transformer or external control system.
Maintenance
Regular maintenance ensures optimal performance and longevity of your well light.
- Cleaning: Periodically clean the glass lens and fixture housing with a soft, damp cloth to remove dirt, debris, and mineral deposits. Avoid abrasive cleaners that could scratch the finish or glass.
- Lamp Replacement: To replace the MR16 lamp, ensure power is disconnected. Carefully remove the top cover of the fixture (usually by unscrewing retaining screws). Gently pull out the old MR16 lamp and insert a new 12V, 20-watt (or less) MR16 lamp. Reassemble the cover, ensuring a tight seal.
- Inspection: Annually inspect wiring connections for corrosion or damage. Check the fixture for any signs of wear or damage to the housing or lens.
- Drainage: Ensure the area around the fixture maintains good drainage to prevent water from sitting on the lens or around the housing.
Troubleshooting
If your FG320 well light is not functioning correctly, refer to the following table for common issues and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power to transformer. Faulty lamp. Loose wiring connection. Faulty transformer. | Check circuit breaker. Replace MR16 lamp. Inspect and secure all wire connections. Test transformer output. |
| Light flickers or is dim. | Low voltage. Loose connection. Corroded wiring. | Check transformer voltage output. Tighten all connections. Clean or replace corroded wires/connectors. |
| Water inside fixture. | Improper seal during reassembly. Damaged lens or housing. Poor drainage around fixture. | Ensure all seals are tight after lamp replacement. Inspect for cracks; replace fixture if damaged. Improve drainage around the installation site. |
