4.
Wrap 5 or 6 turns of Teflon tape on the end of
the pipe nipple and install a 3/8 NPT brass elbow
while holding the pipe nipple from rotating. Orient
the elbow to point straight up. See Figure 18.
5.
Install a brass 3/4 NPT female to a 3/8 NPT male
pipe adapter to the elbow using 5-6 turns of Teflon
tape on the male end of the adapter. See Figure 18.
6.
Install the pressure relief valve on the elbow.
Use 5-6 turns of Teflon tape on the male end of
the valve. Install the pressure relief valve so it is
vertical. See Figure 18.
7.
Install a drain pipe from the pressure relief
valve outlet to a safe area. This is a precaution
to prevent the possibility of personal injury or
property damage in the event scalding water is
discharged from the pressure relief valve.
Install the drain pipe so that there is no trapped or
standing water in the piping. Drain piping must be
facing down, terminating with a threadless nipple,
no less than 6" from floor. It must be open with no
reducers or shut-off valves or other restrictions.

Installation & Operation Manual
NOTE: To ensure the continued proper operation of the
pressure relief valve, the valve should be tested once
a year. To test, lift the lever with the circulation system
running to ensure that water will pass through. When
the lever is down, there should be no leaks from the
outlet.

Auxiliary Components, Chlorinators,
Ozone Generators, and Sanitizing
Chemicals
The JXi heater is manufactured with materials that are not
compatible with high concentrations of ozone, chlorine,
bromine, or other sanitizing chemicals. Heater damage
caused by excessive chemicals or improper ozonization is
not covered by the Zodiac Pool Systems, Inc., warranty.
Be sure to adhere to the following:
•
When ozone is injected upstream of the heater,
install an offgas mixing chamber, or an ozone bypass
system between the heater and the ozone injector to
prevent ozone and air from entering the heater.
•
When chemical feeders are used, plumb the feeder
downstream of the heater and install an in-line check
valve between the heater and the feeder (a minimum
of 18 inch is required between the heater and the
check valve).
•
Wire any electrical chemical feeder so that it cannot
operate unless the filter pump is running. If the feeder
has an independent clock control, synchronize it with
the filter clock.
•
Never deposit chemicals directly in the pool
skimmer.
Section 6. Electrical
Connections
ELECTRICAL SHOCK HAZARD. This heater contains
wiring that carries high voltage. Contact with these
wires may result in severe injury or death.
Label all wires prior to disconnection when servicing
controls. Wiring errors can cause improper and dan-
gerous operation.
Verify proper operation after servicing.
