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 4 inches above ground level and 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 5 feet of the pool, using a No. 8 AWG bond
wire. Bond connection is located at the rear of the niche.
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. The connection inside the niche must
be sealed with a listed sealant such as 3M Scotchcast.
DANGER
RISK OF ELECTRICAL SHOCK OR ELECTROCUTION
For proper bonding and grounding connections, use only Pentair Water Pool and Spa 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.
