Orientation, Luminaire Housing and Mounting Bracket. If orientation of a swimming pool
luminaire housing (forming shell) or mounting bracket is relied upon to orient the luminaire in
a position necessary for its intended performance, the luminaire housing or mounting
bracket is marked to indicate the position in which it is to be installed.
Underwater Luminaires for Aboveground Non-Storable Swimming Pools. These
luminaires are intended only for permanent installation through or on the wall of an
aboveground non-storable pool. They are intended to be installed with the top of the lens not
less than 8 nor more than 10 inches below the top of the pool wall, unless the luminaire is
otherwise marked. They are intended to be permanently connected to the supply with
conduit. They may — for installation, maintenance or servicing — employ a maximum 5 feet
length of jacketed flexible cord permanently connected between integral components of the
luminaire. The installation instructions accompanying a luminaire with a non-enclosed
flexible cord describe the method of proper routing and securement of the flexible cord and
the method for installation of any guards or structural members to reduce the likelihood of
unacceptable stress being imposed on the flexible cord.
Fresh and/or Sea Water Use. Luminaires for swimming pools filled with tap (municipal) or
well water, including water that has been salt-treated for chlorine or bromine generation, are
marked as suitable for fresh water. Luminaires for swimming pools filled with sea water are
marked as suitable for sea water. Luminaires that have been evaluated for both applications
may be marked for both.
Submerse Before Lighting. Luminaires that have been investigated for operation only
while in contact with water are marked, where visible after installation, ―CAUTION — To
reduce the risk of electric shock, submerse before lighting‖.
Special Markings:
One-Time Thermal Protection. Swimming pool luminaires employing a one-time operation,
thermal sensitive device are marked ―Out of water operation (for longer than 3 min.) will
permanently disable luminaire.‖ Words in parentheses are optional.
Inoperable Out of Water. Swimming pool luminaires designed to be inoperable when not
submerged are marked ―This luminaire will not light out of water.‖
1.5. POTTING COMPOUNDS
General. This Listing covers compounds intended to encapsulate the grounding and
bonding conductor splices or terminations in swimming pool and spa equipment such as
luminaires, luminaire housings (forming shells) and junction boxes where the splices or
termination may be exposed to fresh water pool or fountain water and sunlight for varying
lengths of time, including continuous exposure.
These potting compounds are also suitable for use to fill underwater junction boxes. The
container or package is marked to identify that they have been evaluated for adhering to
stainless steel, copper alloy, and any other materials, if applicable.
Listing Mark. The Listing Mark of Underwriters Laboratories is provided on the smallest unit
container in which the product is packaged. The UL Listing Mark includes the product name
―Swimming Pool, Fountain and Spa Equipment Conductor Splice Potting Compound.‖ Any
of the three locations — ―swimming pool,‖ ―fountain‖ or ―spa equipment‖ — may be omitted.
