Installation & Operation Manual
5.2
Plumbing Connections
The heater has a standard 50 mm (2") water manifold and
coupling design. With this feature, only nominal 50 mm
(2") PVC or CPVC may be connected to the heater. Zodiac
Australia Pty Ltd recommend the use of 50mm (2") pipe
with a minimum of 40mm (1.5") to be fitted 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,
see
Figure 2
, before a fi nal location and orientation for the appliance
is determined.
• Turn off all power to the heater at the breaker.
• Ensure that the pump is off and will remain off for
the duration of the procedure.
a
Remove the four black screws securing the heater
top panel to the heater body.
b
Lift heater top panel. Be careful not to damage or
apply undue stress to the user interface wiring.
c
Rotate the heater top panel 180°.
• Place heater top panel securely on heater body.
• Secure with the four screws removed in step “a”.
•
Restore power to the heater.
•
Return heater to normal operation.
5.2.2
Water Inlet Piping
There are two options for water inlet connections on the
JXi. Both configurations use the same water outlet to
return heated water to the pool. Be sure to check flow
rates as outlined in
Section 5.1
and if necessary make
provisions for and ensure sufficient 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 Versa Plumb™
sweep elbow. Plumbing in this configuration can increase
hydraulic efficiency particularly when used in a system
with other Versa Plumb compatible Equipment. See
Figure 8.
The sweep elbow also provides the advantage of its
exclusive interface with the AquaLink
®
RS temperature
sensor.
The side inlet is positioned at a 26 cm (10.13") center
height providing an ideal height for replacement or new
construction plumbing.
• Turn off all power to the heater at the breaker.
• Turn off main gas supply to heater.
• Ensure that the pump is off and will remain off for
the duration of the procedure.
•
Do a dry fit test of cut pipe lengths in order to ensure
proper seating of the union tailpiece and o-ring.
Make 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 9.
• Use approved NSF adhesive to glue the tailpiece onto
the cut pipe, or sweep elbow.
NOTE:
Zodiac recommends Weld-On® 724TM PVC to
CPVC Cement to glue Schedule 40 PVC.
