5.6 Pressure Relief Valve and
temperature Relief Valve
A pressure relief valve (PRV) is recommended in
all installations, and is mandatory in any installation
in which the water fl ow can be shut off between the
heater outlet and the pool/spa.
Some local codes may also require installation of a
temperature relief valve. Check with your local codes for
requirements in your area. The valve setting should be
in accordance with local codes. The U.S. Product Safety
Commission recommends that the water in the pool
does not exceed 104°F. All temperature and/or pressure
relief valves must be listed by a Nationally Recognized
Testing Lab (NRTL) such as ASME, CSA, UL, or ETL.

Follow these steps to install a pressure relief valve.
To protect the threads while drilling, screw the
brass adapter (included with the Jandy PRV kit)
into the blind threaded hole on the top of the
inlet/outlet header.
Using the countersink in the center of the blind
hole as a guide, drill a 1/4 inch hole through the
plastic. See Figure 13.
Open the hole by reaming it with a 3/8 inch drill
bit.
Open the hole again by reaming it with a 1/2 inch
drill bit.
caution
Initially drilling a 1/2" hole without reaming may
cause the bit to "grab" on the plastic. This may
cause personal injury or damage the plastic header.
attention
Si vous commencez à percer le trou de ½" sans
alésage préalable, la mèche risque de « mordre »
dans le plastique. Vous risquez de vous blesser ou
d'endommager le tuyau collecteur de plastique.
Remove the brass adapter and clean the cuttings
out of the hole.
Install the rubber washer at the bottom of the
hole. See Figure 14.
Thread the adapter into the hole and tighten so
that it seals against the rubber washer.
With a permanent marker, place a mark on the
adapter so that the mark faces the same direction
as the water connections on the header.
Remove the adapter from the hole.
