INSTALLATION INSTRUCTIONS

FOR USE ONLY WITH LOW VOLTAGE LANDSCAPE POWER UNITS THAT DO NOT EXCEED 25 AMPS, 15 VOLT MAXIMUM.

WARNING: Luminaires must be installed in accordance with the National Electrical Code (NEC) and local codes. Failure to do so will void the warranty

and may result in serious injury and/or damage to the luminaire.
SAFETY WARNING: Luminaire can become very hot depending on lamp wattage used. Lens and metal around lamp can become hot enough to blister
hands. Particular care should be taken not to locate luminaires where small children can reach them if high wattage lamps are used.
WARNING: Debris must be kept clear from top and interior of ingrade fixtures. Excessive heat could occur that may create a fire hazard and/or harm
the fixture components. Specific attention must be made to never install ingrade fixtures in mulch, wood chips or other potentially ignitable materials.
For installation in potentially ignitable materials, such as mulch and wood chips, installer must use an above-grade mounted fixture. FAILURE TO DO

SO WILL VOID THE WARRANTY AND MAY RESULT IN SERIOUS INJURY AND/OR DAMAGE TO THE FIXTURE AND/OR PROPERTY.
LUMINAIRES ARE NOT TO BE INSTALLED WITHIN 10 FT. (3.05M) OF A POOL OR SPA. SECONDARY CABLE IS NOT TO BE BURIED MORE
THAN 6”. WHEN USING MULTIPLE LUMINAIRES, LOAD IS NOT TO EXCEED THE TOTAL WATTS OF TRANSFORMER RATING. DO NOT USE
EXTENSION CORDS ON POWER UNITS.
NOTE: Always use UL recognized wire connectors for connections.
NOTE: Save these instructions for future reference.

LUMINAIRE MOUNTING:

PRECAUTION: Luminaire is not submersible and adequate drainage

must be provided during installation. It is recommended the luminaire be
surrounded by 3” to 4” of pea gravel or sand to assure proper drainage.
Top of luminaire must be above grade so rain and irrigation water will not
accumulate for long periods of time.

1. To prevent electrical shock, disconnect transformer from electrical supply
before installation or service.

2. Dig hole approximately 12” diameter by 11” deep. This allows
approximately 3” of pea gravel or sand to surround the ABS sleeve.
NOTE: ABS sleeve is reversible. Straight cut end allows flush ground
mounting. Angle cut end requires the top three (3) inches to be installed
above ground for vertical aiming. See fig. 2

3. Place luminaire with support bracket inside ABS sleeve and adjust angle
with adjusting screw on side of support bracket. Push luminaire and support
bracket down to desired level.

4. Run wire pigtail through bottom of ABS sleeve and strip the two (2) leads
from the luminaire wire. Using the two (2) silicone filled safety connectors
(provided), connect the leads from the luminaire to the main supply cable
leads.
NOTE: Luminaires are supplied with 36” of 18-2 cable pigtail for secure
connection to the main supply cable. The wire is to be protected by routing
in close proximity to the luminaire. The wiring should be buried a maximum
depth of 6 inches (15.2 cm) in order to connect to the main supply cable.

4. Backfill hole after installation with pea gravel or sand.

5. Provide power to the luminaire and check for proper operation.

LED:

The operating voltage range for this LED luminaire is 10.5 - 15 volt AC. The Vista electronic driver ensures the LED operates at the intended lumen
output while receiving voltage as low as 6 volts, and as high as 15 VAC, resulting in a balanced lumen output from the first fixture to the last. Eliminating
the dimness issues often attributed to voltage drop.

Note: Operating voltage range for LED luminaries will vary depending on model, style and total number of LEDs. To help determine the operating
voltage range for each Vista luminaire, always consult factory’s specification sheet and/or installation instructions before installation.
