How to Install Landscape Lighting: Basic Instructions
Step 1: Remove the landscape lighting fixtures from the boxes. Check enclosed instructions, and, if required, assemble and add bulbs (lamps).
Step 2: Install the lighting fixtures at their final locations according to your plan. You might want to do a loose installation - meaning don't drive stakes in fully - just in case you want to move the fixture later.
Step 3: Dig 6" deep trenches then run the cable according to your plan. Lay the landscape lighting transformer on a bucket or box and do not mount it at this time. Leave at least 5 feet of slack by the transformer, then loosely run the cable to each fixture according to your layout. Use the provided color tags to mark each cable at both ends (with the same color). Since you may need to move the fixture later, pull a 3-ft. coil of wire at each fixture and bury it near the stake.
Step 4: Connect fixture wires to transformer home run wires. Use direct burial connectors or hubs to connect each landscape lighting fixture to the cable. You can choose to use a hub system to centralize cable splices in each fixture region to make future troubleshooting much easier.
Step 5: Connect the home run wires to the transformer. One wire from each wire pair will go to the common terminals, and one (from each pair) will go to the 12-volt tap terminal. These terminals are labeled on the transformer, and each can have multiple wires connected to it. Do not use the higher tap voltage terminals at this time, we'll get to that next. Once each wire is connected, you can plug in the transformer and switch the common to the "ON" position.
Step 6: Check that all lights are working. Use a voltmeter to ensure that all LED fixtures are within the 9-15v range. For halogen lamps, the range is 10 to 12v. If you find voltages lower than the minimum, connect that home run to a higher voltage tap so the resulting voltage is within the range.
Step 7: Mount the transformer to the wall, making sure it is at least one foot from the ground. Also plug in any accessories including timers and photocells.
Step 8: Finish off and bury wire runs. Straighten out cable runs and wrap wire around each cable run bundle for a neat finish. For cables that run under turf edges and under mulch beds, consider using a PVC Conduit to enclose the cable. VOLT has a split conduit that can be placed over a wire after the wire has been run. Once cables are placed in the correct position, fill and cover trenches.
Step 9: Aim and Adjust. Make sure you wait for night to fall and fully analyze your landscape lighting before leaving. Make sure the lights are correctly positioned, change any bulbs or optics, check for glare from the fixtures and fine tune. Now, you can enjoy your landscape lighting system.
