Safety Information
WARNING:
- Always disconnect power before installing or servicing the transformer.
- Installation must be performed by a qualified electrician in accordance with all local and national electrical codes.
- Do not immerse the transformer in water. Ensure it is installed in a location protected from direct water exposure.
- Ensure the total wattage of connected fixtures does not exceed the transformer's maximum output (600 watts).
- Use only low-voltage landscape lighting cables and connectors.
Setup and Installation
1. Mounting the Transformer
The MT 600T transformer is designed for wall mounting. Choose a secure, vertical surface near a 120V AC power outlet. Ensure the mounting location is protected from direct weather exposure, such as under an eave or in a sheltered area.
- Mark the desired mounting points on the wall using the transformer's mounting holes as a template.
- Drill pilot holes if necessary and secure the transformer using appropriate screws or anchors for your wall type.
- Ensure the transformer is level and securely fastened to prevent accidental dislodgement.
2. Wiring the Low-Voltage Output
The transformer features multiple low-voltage output terminals. Connect your landscape lighting cables to these terminals.
- Strip approximately 1/2 inch of insulation from the ends of your low-voltage cables.
- Loosen the terminal screws on the desired output terminals (e.g., 12V, 14V, 15V, depending on your fixture requirements).
- Insert the bare wire ends into the terminals and tighten the screws firmly to ensure a secure connection.
- Ensure all connections are tight and no bare wires are exposed that could short circuit.
3. Connecting to Power
The transformer comes with a pre-attached 120V power cord.
- Plug the transformer's power cord into a grounded 120V AC outlet.
- Verify that the outlet is protected by a Ground Fault Circuit Interrupter (GFCI) for outdoor installations.
Operating Instructions
Setting the Mechanical Timer
The MT 600T includes a mechanical timer to automate your lighting system's operation.
- Set Current Time: Rotate the outer dial of the timer clockwise until the current time aligns with the arrow indicator. The dial is marked with 24-hour increments (e.g., 18 for 6 PM).
- Set ON/OFF Times: The timer has small, push-in/pull-out pins around its circumference. Each pin represents a specific time interval (e.g., 15 minutes).
- To set an "ON" period, push the pins inwards for the desired duration.
- To set an "OFF" period, pull the pins outwards for the desired duration.
- Manual Override: The timer typically has a manual override switch (often labeled "ON," "AUTO," "OFF"). Set this switch to "AUTO" for timer-controlled operation. You can switch to "ON" for continuous power or "OFF" to cut power manually.
Testing the System
After setting up the timer and connecting all fixtures:
- Ensure the timer is set to "AUTO" or "ON" for testing.
- Verify that all connected low-voltage lights illuminate correctly.
- If any lights do not work, check wiring connections and bulb integrity.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your Vista Pro transformer.
- Periodic Inspection: Annually inspect the transformer and all wiring for signs of wear, damage, or corrosion. Check for loose connections.
- Cleaning: Keep the transformer's exterior clean and free of debris. Use a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Ventilation: Ensure the transformer's ventilation openings are not obstructed to prevent overheating.
- Timer Battery (if applicable): Some mechanical timers may have a small internal battery for timekeeping during power outages. Consult the timer's specific instructions if it has such a feature and requires battery replacement.
