5. Setup and Installation
Follow these steps for proper installation of your landscape lighting transformer:
- Prepare the Installation Location: Choose a suitable outdoor location for wall mounting, ensuring it is at least 1 foot (30 cm) above ground and away from water sources like pools or spas. The location should also have access to a covered GFCI outlet.
- Mount the Power Pack: Use the provided screws and anchor walls to securely mount the transformer to a sturdy surface. Ensure the mounting screws are spaced approximately 3 inches (7.6 cm) apart horizontally.
- Connect Landscape Lighting Cables: Strip 5/8 inch (1.6 cm) of insulation from the ends of your low voltage landscape lighting cables. Connect these cables to the transformer's output terminals. Ensure a secure connection for each wire.
- Mount the Photo Eye Sensor: The detachable photocell sensor should be mounted in a location that receives natural light, free from obstructions or artificial light sources that could interfere with its operation. Secure the sensor using its bracket.
- Plug into Power: Once all connections are secure and the transformer is mounted, plug the transformer's power cord into a covered GFCI (Ground Fault Circuit Interrupter) outlet. Ensure the outlet is at least 12 inches (30 cm) above ground level.

6. Operating Modes and Settings
The Malibu transformer offers five distinct operating modes, selectable via the rotary dial on the control panel, to meet various lighting needs and optimize energy usage. The digital display allows for precise time setting.
Figure 7: Control panel and operating instructions for the Malibu transformer.
Setting the Clock:
Use the "CLOCK" button and the up/down arrows to set the current time. Ensure the AM/PM indicator is correct.
Operating Modes:
- OFF: The power pack is completely off. Lights will not illuminate.
- ON: The power pack is continuously on. Lights will remain illuminated until manually turned off or the mode is changed.
- AUTO (Dusk to Dawn): In this mode, the detachable photocell sensor activates the lights at dusk and automatically deactivates them at dawn. This provides fully automated, energy-efficient operation.
- Countdown Timer (4, 6, 8, 10 Hours): This mode utilizes the photocell sensor to turn lights on at dusk, and then automatically turns them off after a set duration of 4, 6, 8, or 10 hours. Select the desired duration using the rotary dial.

- TIMER ON / TIMER OFF: This mode allows you to set specific ON and OFF times for your lighting system. Use the "TIMED ON" and "TIMED OFF" buttons with the up/down arrows to program your desired schedule.
- PHOTO ON / TIMED OFF: Lights turn on at dusk (via photocell) and turn off at a specific time you set. Use the "TIMED OFF" button to program the desired shut-off time.

The transformer includes a memory function that preserves the selected mode and time settings during power outages, ensuring uninterrupted operation upon restart.
7. Maintenance
Your Malibu transformer is designed for durability and minimal maintenance. However, periodic checks can ensure optimal performance and longevity.
- Cleaning: Periodically wipe down the exterior of the transformer with a damp cloth to remove dirt and debris. Do not use abrasive cleaners or submerge the unit.
- Connection Check: Annually inspect all wire connections to ensure they remain secure and free from corrosion.
- Photocell Sensor: Ensure the photocell sensor is clean and unobstructed to guarantee accurate dusk-to-dawn operation.
- Weather Resistance: The transformer is constructed from durable, waterproof, and high-performance plastic materials, engineered to withstand various adverse weather conditions. Its corrosion-resistant properties ensure reliability in outdoor environments.
