Section II. Vinyl Liner/Fiberglass Pool Installation Instructions
1. Punch or drill 6 sealing holes, 2 retainer holes and large panel hole, as per circular panel cut-out information.
NOTE
One of the two gaskets has larger holes to go over the retainer screw head.
2. Make sure double wall gasket is around the niche flange. Insert the stainless steel light niche through wall panel from inside
the pool.
a. Align the two retainer screws holes (diametrically opposite one another at top and bottom) of the light niche with
those that were drilled or punched in the wall panel.
b. Insert the two fillister head retainer screws through light niche and wall panel.
c. Align the holes of the back-up ring and rear gasket, (the gasket without larger holes), with the holes on the back
side of the wall panel.
d. Fasten the back-up ring and second gasket to the back of the wall panel by tightening the two fillister head retainer
screws. At this point the wall panel is sandwiched by two gaskets.
3. If this is a vinyl pool, install the vinyl liner. For fiberglass pools skip to step 4.
4. Align front gasket (gasket with the two larger holes to go over the retainer screw heads) with brass-chrome sealing
ring and fasten tightly to the light niche with the six 10-24 x 1 1/8 inch flat stainless screws provided for that purpose.
a. Be sure the two countersinks on the back of the sealing ring (top and bottom) line up with the heads of the retainer
screws, and the two large holes in the third gasket are placed over the heads of the retainer screws.
b. Be sure the pilot screw hole of the sealing ring is at the center top. For vinyl liner pools, pierce the liner through
the sealing ring holes, one at a time, and insert and tighten each screw at it's hole pierced.
c. Each screw should be inserted and tightened through the sealing ring (in proper order), front gasket, vinyl liner
if there is one, flange of the light niche, double wall gasket, wall panel, rear gasket and into the back-up ring.
5. For a vinyl liner pool, cut out vinyl liner along inside diameter edge of the sealing ring.
6. Connect rigid conduit from niche-fixture housing to junction box. The junction box (or for 12 volt models, the low
voltage transformer) must be located at least four (4) inches above ground level and eight (8) inches above water
level and at least 48 inches from the edge of the pool.
7. Bond the niche-fixture housing to all other metallic items within five (5) feet of the pool, using a No. 8 AWG wire.
Bond connection is located at the rear of the niche. See NEC 680.26 code requirement.
8. If non-metallic conduit is used, a No. 8 AWG bonding/grounding wire must be installed through the conduit from
the Junction Box to the bonding/grounding lug inside the niche. Seal the wire/lug connection with a listed sealant such
as 3M
™
Scotchcast
™
Potting Kit 2136 or equivalent, to protect the connection from possible pool water corrosion.
See figure 2. See NEC 680.23 code requirement.
For proper bonding and grounding connections, use only Pentair underwater light fixtures with this niche-fixture
housing. Failure to do so could create an electrical hazard which would result in death or serious injury to pool users,
installers and others.
DANGER

This niche - fixture housing must be installed by a licensed or certified electrician in accordance with the National Electrical Code
and all applicable local codes and ordinances. Improper installation will create an electrical hazard which could result in death
or serious injury to pool users, installers or others due to electrical shock, and may also cause damage to property. Read and
