HAYWARD SP0600U User Manual
1. All DuraNiche™ underwater lighting fixture housings are Underwriters Laboratories (UL) Listed under File E 39338- Category
WBDT. These niches are New York City (NYC) Bureau of Electrical Control approved for use with low voltage (12 volt) lighting fixtures. U.L. Listed for fresh water and complies with 1999 National Electrical Code [NEC].
2. DuraNiche™ model SP0600U and SP0607 underwater fixture housings are UL Listed only for use with Hayward Submersible
Light Fixture Series SP 0540, SP 0570, SP 0580 and SP 0580S. Model SP 0601 Underwater Light Fixture Housing (Niche) is UL
Listed for use with Hayward Submersible Light Fixture Series SP 0590.
3. All DuraNiche™ underwater lighting fixture housings must be installed in compliance with Article 680 of the National Electrical
Code (NEC) or other applicable electrical codes and with any applicable building codes. Article 680 requires that light fixtures be
installed with the top of the fixture lens at least 18 inches below the normal water level of the pool or spa.
4. All DuraNiche™ underwater lighting fixture housings are provided with three (3) UL Listed
Conduit Fittings. A 1" trade size -45° sweep elbow is provided for the purpose of directing
the conduit pipe towards the SP 0680/ SP 0681 Listed Junction Box location. A 1" conduit
pipe coupling is provided for the purpose of connecting the conduit pipe to the 45° sweep
elbow. A 1" - 3/4" reducer bushing is provided to permit the use (in conjunction with the 1"
coupling) of 3/4" conduit pipe. These conduit fittings must be cemented to the fixture housing (niche), field supplied conduit pipe and to other conduit fittings using approved PVC
primer and cement.
5. All DuraNiche™ underwater lighting fixture housings are provided with a combination bonding/grounding connector. The outside
connection is the bonding connector as required by Article 680-22 of the NEC. The NEC requires that the bonding wire be AWG 8
or larger. Local codes may require a continuous loop and may require that the bonding point on the fixture housing (niche) be
encapsulated. The inside connection is the grounding connector as required by Article 680-20 (b) of the NEC. The NEC requires
that where a nonmetallic conduit is used, an AWG 8 insulated copper conductor be installed in this conduit. This conductor is to be
connected to the niche grounding connector. The connector and wire termination must be encapsulated in 3M Inc. Scotch Cast
Wet Niche Potting Compound No. 2135 (UL File E130394) or equivalent to protect such connection from the possible deteriorating effect of pool water.
6. All DuraNiche™ niches are equipped with Internally-threaded connection for pressure testing of conduit line before installing light.

INSTALLATION INSTRUCTIONS
SAVE THESE INSTRUCTIONS
Unlike metallic niches, DuraNiche™ niches are
injection-molded of PVC for superior performance,
non-corrosive durability and plumbing versatility plus the lowest installed cost.
The ability to accept PVC over expensive metal
conduit enables DuraNiche™ to offer true bottom
line savings in materials, as well as time to install.
DuraNiche™ comes in three models for concrete/gunite pools,
vinyl/ fiberglass pools, or for concrete/gunite spas. When paired
with a Hayward AstroLite™ or AstroLite II™ light fixture, you have
the best quality and value in a lighting system available anywhere.
To facilitate installation, all DuraNiche™ fixture housings are
packed with U.L. listed conduit fittings (reducer, elbow, and coupling.)

FEATURES COMMON TO SP0600U AND SP0601U- FOR CONCRETE POOLS
1. 3/4" set-back plaster flange with tie-off holes to secure to rebar and assure positive positioning during guniting.
2. Unique 90° ledge at the flange bottom prevents "slumping" during plastering.
3. Niche cover (see back page) included with each niche, protects the niche and mounting threads during guniting.
4. The SP0601U small diameter niche has extra space for easy coiling and storage of the relamping cord.
Models SP0600U (Pool) and SP0601U (Spa) Underwater Lighting Fixture Housings are intended for installation in
pools or spas with floors and walls formed of gunite or concrete (shotcrete) with a concrete reinforcing bar (rebar)
frame. Gunite is a mixture of Portland Cement and sand while shotcrete is a high strength (4000 psi) concrete utilizing Portland Cement and small size aggregate.
The outside shape of the pool or spa is formed from SteelTek or other suitable material.
In some cases, the excavated dirt wall will serve as the outside form. The inside wall of
the pool or spa is formed from rebar that is bent to the desired shape (See Illustration A ).
The distance between the outer and inner wall is called the beam and is typically 8 to 12
inches. Rebar steel should be set at 10” for a 12” beam and 8” for a 10” beam. The distance between the niche flange and the outer wall should be the beam dimension. At all
points where the rebar crosses, tie wire is used to connect the rebar securely.
1. Position the Model SP 0600U (Pool) or SP 0601 U (Spa) between adjacent rebars
such that the niche is held on four sides by sections of rebar. At the time the niches
are installed it may be necessary to add sections of rebar or move existing sections to
one side or another in order to insure that the niche is held securely. See illustration
(B)
THE NEC REQUIRES THAT THE TOP OF THE LIGHT LENS BE AT LEAST 18 INCH-
ES BELOW THE WATER LEVEL. BE SURE TO POSITION NICHE SO THAT YOU
COMPLY WITH THIS REQUIREMENT. SOME INSTALLERS POSITION NICHE 24
INCHES BELOW ANTICIPATED WATER LEVEL TO AVOID ANY INSPECTION
AUTHORITY ISSUES WITH THIS REQUIREMENT.
2. Once the niche(s) has been securely positioned (wedged) in the rebar it must be
securely tied to the rebar with tie wire. Before tying niche in place make certain that
niche is (vertical) plumb, and square to the form and that top of niche (where retaining
screw is located) is at highest point at the 12 O’Clock posiiton. The flanges of Niche
Models SP0600U and SP0601U are provided with .187" diameter holes through which
tie wire may be routed to facilitate securing the niche to the rebar. Tie wire should also
be wrapped tightly around the outer circumference of the niche and then tied to the
rebar. Once the niche is tied in place confirm that it is still plumb and that the distance
from the outer wall to the niche flange is the correct beam dimension
NOTE: The rebar will be approximately 2 inches from where the inside finished surface of
the pool will be. You must be sure to leave approximately 2” between the DuraNiche™
flange and the rebar (see illustration C)
3. After attaching the niche to the rebar of the pool wall and cementing conduit and conduit
fittings in place and connecting the #8 AWG bonding wire to the bonding connector as
described, install the provided DuraNiche™ Cover. The niche cover must be installed in order to prevent gunite or
concrete from entering the inside of the niche during the pouring/shooting process. Cover should be left in place until
the light is installed in the niche. (see illustration C)
4. The outside bonding connection must be inspected before the concrete/gunite, pouring/shooting operation. Follow
applicable codes. It is also necessary to keep concrete or gunite from hardening on the outer edge and flange of the
niche during pouring/shooting.
5. Once the concrete/gunite has completely dried, the niche is ready to be "plastered". Plaster is typically a mixture of
white Portland Cement and marble dust along with some pigment chosen to give the pool water the desired color.
The "plaster" is applied about 1" thick in the area surrounding the niche. The distance between the front edge and
the flange of the niche is filled with plaster.
