Cal Spas A726B Pre-Delivery Manual page 25

Light niche and any metallic items in a 5' (152 cm) radius must be properly
bonded with #8 AWG grounding wire.
1. Connect rigid conduit to the 3/4" hub located at the back of the light
niche and run to a water resistant 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 conduit and all connections must be
leakproof.
2. Feed the light cord through the rigid conduit to the junction box, leaving
at least 4 feet of cord at the end of the light fixture. This slack in the
light cord will allow servicing without draining the spa in the future.
3. Wrap light cord slack around back of light housing and attach light to
niche with mounting screw.
4. Cut the cord at the junction box, leaving at least 6" (15 cm) of cord to
make connections.
5. Strip 6" (15 cm) of the out cord jacket to expose the three insulated
wires. Be careful not to damage the insulation on the three inner
wires.
6. Connect the three wires to the corresponding circuit wires in the
junction box and secure the junction box cover in place.
7. Replace the light assembly in the niche and tighten the special pilot
screw.
8. Fill the spa until the underwater light is completely 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.
