header surface. Scratches may compromise the
seal integrity.
12. Place the inlet/outlet header over the bolts and
gasketed tubes on the left side of the tube assem-
bly. Align the bolt and tube holes in the header
with the bolts and tubes in the header bar and
slide the assembly together. Make sure the spacer
is in place.
13. Thread on the 10 bolts and washers and hand
tighten.
14. Place the return header over the bolts and gasket-

16. Use a torque wrench to tighten the bolts on each
header to four (4) foot-pounds. The bolts must be
tightened in the sequence indicated in Figure 14.
CAUTION
Failure to tighten the header as indicated in step 16
may cause the header to leak or become perma-
nently damaged from warping.
ATTENTION

to the water pressure switch back to the Power
Interface board in the raceway. Reconnect the
yellow two-pin connector to the yellow "Water
Press" connector on the Power Interface board.
21. Use plastic wire ties to refasten the temperature
sensor, high limit switch and water pressure
switch wires to each other. Bundle the wires near
the control panel and fasten them with a wire tie.
NOTE Be sure that none of the wires are in contact
with a sharp edge or a hot surface.

Connections at Heater

The LXi heater has a standard 2" water header
and coupling design. With this feature, only nomi-
nal two inch PVC or CPVC may be connected to the
heater. However, by installing the appropriate pipe
adapters and two short pieces of two inch plastic pipe
(supplied by the installer), any size existing pipe may
be fi tted to the heater.
The LXi heater also comes with a Jandy Sweep
Elbow for increased hydraulic performance and ef-
fi ciency. The sweep elbow also provides the advantage
of its exclusive interface with the Jandy AquaLink
temperature sensor.
To install the Jandy Sweep Elbow follow these
instructions:
WARNING
To avoid an electrical shock hazard, which can result
in serious injury or death, ensure that all electrical
power to the system is turned off before approaching,
inspecting or troubleshooting any leaking valves
or plumbing that may have caused other electrical
devices in the surrounding area to get wet.
