Installation & Operation Manual
5.2
Plumbing Connections
The heater has a standard 2 inch water manifold and
coupling design. With this feature, only nominal two inch
PVC or CPVC may be connected to the heater. However,
by installing appropriate pipe adapters and two-inch pipe
(supplied by the installer), any size existing pipe may be
fi tted to the heater.
5.2.1
Reversing Plumbing Connections
The JXi heater is shipped with the manifold on the right
side by default. If necessary the water connections can be
orientated to the left side by rotating the top panel of the
appliance.
NOTE: The electrical raceway, transformer, PIB, Ignition control
and voltage selector board are all accessed through the default front
panel. Special considerations should be made for service clearance,

5.2.2
Water Inlet Piping
There are two options for water inlet connections on
the JXi. Both confi gurations use the same water outlet
to return heated water to the pool. Be sure to check
fl ow rates as outlined in
Section 5.1
and if necessary
make provisions for and ensure suffi cient space for the
installation of a manual bypass valve as outlined in
Section 5.1.1.
The top inlet is intended for use with the Jandy
Versa Plumb
®
sweep elbow. Plumbing in this
confi guration can increase hydraulic effi ciency
particularly when used in a system with other Versa
Plumb compatible Jandy Pro Series Equipment.

The side inlet is positioned at a 10 1/8” (255.7 cm) center
height providing an ideal height for replacement unit or
new construction plumbing.

adjustments to pipe length or positioning as needed.
• Clean all adhesion surfaces with an appropriate NSF
®
approved all purpose cleaner/primer.
• Slide the union nut onto the cut pipe length. or
sweep elbow. Ensure proper nut orientation with
threads directed towards the heater manifold. See
Figure 10.
