provide left-side water connections. This is done by
removing the water headers and re-installing them
opposite to their original location. Some of the heater
wiring and control components must be relocated, so
this change must be done only by a trained service
technician.
Water connection reversal is illustrated in Figures
19 and 20. Proceed as follows:
1. Remove the vent exhaust grille by removing
the four screws which retain it. Retain these
and all other parts for later reassembly.
2. Remove the top cover by removing the
screws around the edges, under the overhang.
3. Remove the header covers. Note that the
return header cover is retained by wing nut
fasteners inside the heater.
4. Disconnect the pressure switch wires and
remove the pressure switch tube from the
inlet/outlet header by unscrewing the brass
fi tting.
5. Remove the temperature control sensor by
removing the retainer bracket and its cap
screws.
6. Disconnect the limit switch wires from the
limit switches. The limit switches and the
short wire between them may be left in place.
7. Remove both headers by unscrewing eight
cap screws retaining each header.
8. Install the inlet/outlet header on the left side
of the heater and the return header on the
right. Position gaskets carefully to avoid
water leaks.
9. Re-route the limit switch wires in front of the
venturi tailpipe and attach them to the limit
switches.
10. Re-route the temperature sensor wires in
front of the venturi tailpipe and insert the
sensor into the header. When the inlet/outlet
header is on the left side, the sensor opening
is at the rear. Re-install the retainer bracket
and screw.
11. Re-install the pressure switch tube and
fi tting. Relocate fi tting.
12. Adjust wiring and pressure switch tube
routing so that they don't rest on sharp edges
or on the hot surfaces of the combustion
chamber. The combustion chamber is the
portion of the assembly just above the heat
headers.
13. Re-assemble all other components and
fasteners.
2K-2. Pool/Spa Piping Systems
Figure 21 illustrates typical piping for pool
equipment in pool/spa combination pools. With
its Flex-Temp temperature control, the Hi-E
2 is
particularly suitable for this type of pool installation.
Wiring should include a means to prevent
operation of the heater when there is no water fl ow.
This is typically done with a time clock “Fireman’s
Switch” as discussed in Section 2J-3.
2J-2. Bonding
The National Electrical Code and most other
codes require that all metallic components of a pool
structure, including reinforcing steel, metal fi ttings
and above ground equipment be bonded together with
a solid copper conductor not smaller than a number
8 wire. The heater, along with pumps and other such
equipment must be connected to this bonding grid. A
special labeled bonding lug is provided on the right
side of the heater to accommodate this requirement.
2J-3. Auxiliary Time Clock Wiring
If a time clock is provided to control the pool
fi lter pump, it should have a separate low-voltage
(Fireman’s) switch for the heater. Route the heater’s
24 VAC control circuit through this switch as
shown in Figures 17 and 18. To do this, remove the
“jumper” from the terminal block in the heater control
compartment. Con nect two wires to this terminal
block and route them to the Fireman’s switch at the
time clock. Provide wiring of at least 18 gauge with
in su la tion at least 3/64" thick and having a tem per a ture
rating of at least 90
o
C.
2J-4. Remote Operation
The Hi-E
2 pool/spa heater controls can be
wired for remote operation. Jandy remote controls
are available through the local dealer or distributor.
The CS-02 remote control switches between the two
temperature controllers and turns the heater on and
off. The CS-04 has the same controls as the CS-02 and
includes a remote temperature controller.
An interrupt (On-Off) type remote control can
be connected by removing the jumper wire on the
terminal block located in the control compartment
(see Figure 18) and connecting the two wires from
the remote to the two terminals on the terminal block.
This type of remote control will turn the heater on or
off, but will not switch between the two temperature
controllers on the Flex-Temp control panel.
To connect a three-wire remote control harness
(not supplied with the heater), order an E0120000 wire
harness assembly which connects to the Flex-Temp
control panel. Installation instructions are included
with the wire harness assembly.
