4. Open the hole again by reaming it with a ½ inch
drill bit.
CAUTION
Initially drilling a
½
inch 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 pouce
sans alésage préalable, la mèche risque de «
mordre » dans le plastique. Vous risquez de vous
blesser ou d’endommager le tuyau collecteur de
plastique.
5. Remove the brass adapter and clean the cuttings
out of the hole.
6. Install the rubber washer at the bottom of the
hole. See Figure 19.
7. Thread the adapter into the hole and tighten so
that it seals against the rubber washer.

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 set-
ting should be in accordance with local codes. The
U.S. Product Safety Commission recommends that
the water in the pool does not exceed 40°C (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.
A pressure relief valve is not supplied with the
LXi heater. However, it is recommended that a pres-
sure relief valve be installed and may even be re-
quired by local codes. Be sure to check any applicable
installation codes in your area to determine whether
a pressure relief valve is required. See
Section 11.2
(Parts List) of this manual for the appropriate kit part
number.
The maximum working pressure of this heater is
75 psi. Be sure to take into consideration the maximum
allowable pressure of the other components in the sys-
tem when selecting a PRV. Any pressure relief valve
installed must comply with provisions of the standard
described in ANSI Z21.22 for the United Sates or CSA
4.4 in Canada.
Follow these steps to install a pressure relief valve:
1. To protect the threads while drilling, screw the
brass adapter (included with the Zodiac PRV
kit) into the blind threaded hole on the top of the
inlet/outlet header.
2. Using the countersink in the center of the blind
hole as a guide, drill a ¼ inch hole through the
plastic. See Figure 18.
3. Open the hole by reaming it with a ⅜ inch drill
bit.
