Specifications

Failure to tighten the header as indicated in step
16 may cause the header to leak or become per-
manently damaged from warping.
CAUTION
Si le tuyau collecteur n’est pas serré conformé-
ment aux directives des l'étape 16, il risque
d’avoir des fuites ou de s’endommager de façon
permanente.
ATTENTION
17. Remove the 3/4 inch button plug located in the
left side panel below the inlet/outlet header and
replace with the 3/4 inch wire grommet from the
right side panel below the return header. The high
limit leads were routed through this grommet prior
to removal in step 5. Install the 3/4 inch plug in
the opening where the 3/4 inch wire grommet was
removed.
18. Route the blue two-pin connector attached to the
high limit switches back to the Power Interface
board in the raceway. Reconnect the blue
"HiLimit" two-pin connector to the blue "HiLimit"
connector on the Power Interface board.
19. Route the wires that attach to the temperature
sensor back to the Power Interface board in the
raceway. Reconnect the wires to the "WATER
TEMP" terminals on the Power Interface board.
20. Install the longer syphon loop tube (part number
R0483601) to the pressure switch and locate the
the pressure switch in the front area of the cabinet.
21. Route the yellow two-pin connector that connects
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.
22. 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.
In order to prevent property damage or injury, be
sure that none of the wires are in contact with a
sharp edge or a hot surface.
CAUTION
An d'empêcher des dégâts matériels ou des
blessures, assurez-vous qu'aucun des ls n'est
en contact avec un bord tranchant ou une surface
chaude.
ATTENTION
23. Install the return header side cover plate on the
right side of the unit.
24. Install the I/O header side cover plates, top and
bottom on the left side of the unit.
25. Replace the front panel (door).
5.5 Connections at Heater
The Legacy Model LRZ electronic heater has a
standard two (2) inch water header and coupling design.
With this feature, only nominal 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 tted to the heater.
To connect a section of 2” PVC or CPVC pipe to
the heater, rst slip a coupling nut onto the pipe. Then
prepare the end of the pipe with the proper PVC/CPVC
primer and glue. Follow the manufacturer’s instructions
provided with the primer and glue for preparation
procedures and curing times. Apply the slip-t side of
the coupling to the end of the pipe. Allow the glue to
cure completely. Set the o-ring into the groove on the
face of the coupling. Slide the coupling nut up to the
coupling and tighten it to the threaded connection on the
header. See Figure 12.
5.6 Pressure Relief Valve and
Temperature Relief Valve
A pressure relief valve (PRV) is recommended in
all installations, and is mandatory in any installation in
