Inground Spa Light Installation In-

structions

On spas ordered with inground lights, the factory
installs the light niche for you. The next steps of
installation should be performed by a qualied licensed
electrician.
Always read and follow light manufacturer’s safety
and installation instructions prior to installation and
operation. Incorrect installation may damage the light
and void its warranty.
The light circuit must be on a GFCI protected service
(alone or with a switch).
The water resistant junction box (or for 12 volt models,
the low voltage transformer) must be located:
at least 8” (20 cm) above water level•
at least 4” (10 cm) above ground level, and•
at least 48” (121 cm) away from the spa.•
See gure below.
Light niche and any metallic items in a 5’ (152 cm)
radius must be properly bonded with #8 AWG
grounding wire.
Connect rigid conduit to the 3/4” hub located at 1. the back of the light niche and run to a water re-
sistant junction box (or for 12 volt models to a low
voltage transformer) no further than 25’ (7.6m).
Remember this is a water cooled light, so the con-
duit and all connections must be leakproof.
Feed the light cord through the rigid conduit to 2. the junction box, leaving at least 4 feet of cord at
the end of the light xture. This slack in the light
cord will allow servicing without draining the spa
in the future.
Wrap light cord slack around back of light housing 3. and attach light to niche with mounting screw.
Cut the cord at the junction box, leaving at least 4. 6” (15 cm) of cord to make connections.
Strip 6” (15 cm) of the out cord jacket to expose 5. the three insulated wires. Be careful not to dam-
age the insulation on the three inner wires.
Connect the three wires to the corresponding cir-6. cuit wires in the junction box and secure the junc-
tion box cover in place.
Replace the light assembly in the niche and tight-7. en the special pilot screw.
Fill the spa until the underwater light is completely 8. submerged in water before operating the light for
more than 10 seconds. Turn on the main switch or
circuit breaker, as well as the spa light control, to
check for proper operation
Important: Make sure spa light is submerged in
at least 18” of water prior to testing.
