Installation & Operation Manual
• Once an operational and correctly sized pressure
switch has been confi rmed, set the heater control to
either POOL or SPA. Heater should start.
•
With your fi ngers, turn the adjustment sprocket very
slowly clockwise until the heater goes off.
• Slowly turn the pressure switch adjustment sprocket
counterclockwise one-quarter turn. The heater should
come back on. See
Figure 11.
•
Check the adjustment by turning the fi lter pump
OFF. The burner should shut off immediately. If
it does not, restart the fi lter pump and repeat the
preceding step. Check the adjustment again. If you
are still unable to successfully set your water pressure
switch please contact your local Jandy distributor or
call technical support at 800.822.7933. Additional
information can be found at www.jandy.com.
•
Return the temperature control to the desired
temperature.
5.4
Check Valve Installation
When any equipment is located below the surface of the
pool or spa, back-siphoning can occur, which can draw
water backwards through the circulation system. This can
be particularly concerning if chemically treated water
is allowed to fl ow back into equipment such as heaters,
fi lters and pumps. Make sure any chemical feeder or
chlorination system outlet lines are downstream of the
heater and a positive seal noncorrosive check valve
is installed between the sanitation equipment and the
heater. Always install a check valve if there is sanitation
equipment installed in the system. Do not install any
shutoff valve in the piping between the heater outlet and
the pool.
WARNING
A check valve can interfere with the proper operation of certain Suc-
tion Vacuum Release System (SVRS) products. To avoid possible
entrapment hazard, serious injury, or death, make sure to review the
operation/owners manual of your particular SVRS product before
installing the check valve.
5.5
Pressure Relief Valve Installation
A pressure relief valve (PRV) is recommended in all
installations, and is mandatory in any installation in
which the water fl ow can be restricted between the heater
outlet and the pool/spa. A pressure relief valve may
also be required by local codes. Be sure to check any
applicable installation codes in your area to determine
whether a pressure relief valve is required.
A pressure relief valve is not supplied with the JXi heater.
However, Jandy does offer a PRV Kit # R0336101. The
following instructions are for use with this kit only. All
other equipment installations need to be in accordance
with the manufacturers instructions.
The maximum working pressure of this heater is 50
psi. Be sure to take into consideration the maximum
allowable pressure of the other components in the system
when installing 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.
5.5.1
Install pressure relief valve kit # R0336101
• Turn off the electrical power to the heater.
• Turn off the main gas supply to the heater.
• If the heater has been operating, ensure you allow
enough time for remaining water in the heat
exchanger to cool down before beginning. It is
recommended that protective gloves be worn during
the entire procedure.
•
Make sure the fi lter pump is off and will remain off
for the duration of the installation procedure.
• If the heater is below the surface level of the water in
the pool or spa, close all shut-off valves between the
heater and the pool.
