Section I. Installing light fixture
during new pool construction
A. Preparatory steps which must be
completed by the electrician before the
light fixture is installed; see Figure 1.
1. Verify that the pool meets the
requirements of the current National
Electrical Code and all local codes
and ordinances. A licensed or certified
electrician must install the electrical
system to meet or exceed those
requirements before the underwater
light is installed. Some of the
requirements of the National Electrical
Code which the pool’s electrical system must meet are as follows:
a. The lighting circuit has a Ground Fault Circuit Interrupter (GFCI), and has an appropriately rated circuit breaker.
b. The Junction Box (or, for 12 volt models, the low voltage transformer) is located at least 8 inches above water
level and at least 48 inches from the edge of the pool; see Figure 1.
c. The light fixture and all metal items within 5 feet of the pool are properly electrically bonded.
d. The wet niche must be properly installed so the pilot screw hole is at the 12 o’clock position and that the top edge
of the underwater light’s lens is at least 18 inches below the surface of the water in the pool; see Figure 1.
NOTE
The required orientation of all Pentair lights is with the pilot screw at the 12 o’clock position. This is guaranteed by proper niche
installation.
e. The wet niche is properly electrically bonded and grounded via the No. 8 AWG ground connector located at
the rear of the niche; see Figure 1.
NOTE
The pool or spa electrical system can be verified with a Pool and Spa Electrical Qualification Test kit. The test kit is available from
Pentair Water Pool and Spa. The electrical system inspection using this kit must be performed by trained and certified personnel.
2. To be certain that the pool’s electrical system meets all applicable requirements, the electrician should also consult the
local building department.
3. Use only Pentair Water Pool and Spa wet niches to insure proper bonding and grounding connections.
B. Steps to perform after the electrical system requirements are met.
1. Feed cord through conduit to Junction Box, leaving at least 4 feet of cord at the light fixture to coil around the light; see
Figure 1. This 4 feet of cord around the light allows the light to be serviced after the pool is filled with water.
2. Cut the cord at the Junction Box, leaving at least 6 inches of cord to make connections.
3. Strip 6 inches of the outer cord jacket to expose the three insulated wires--be careful not to damage the insulation on
the three inner wires.
4. Connect all three wires to the corresponding circuit wires in the Junction Box and secure the Junction Box cover in place.
WARNING
Never operate this underwater light for more than 10 seconds unless it is totally submerged in water. Without total submersion,
the light assembly will get extremely hot, which may result in serious burns or in breakage of the lamp or lens. This may result
in serious injury to pool users, installers, or bystanders, or in damage to property.
5. Replace the light assembly into the niche and tighten the special pilot screw.
