Hi-E2
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 in the USA 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. Equipment must be connected
to this bonding grid if located within 5 ft. (3 meters in
Canada) of the inside walls of the pool/spa. Although
Jandy Pool Heaters are not intended to be installed in
close proximity to the pool or spa, if bonding to the
grid is required by local codes or authorities, 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
o
rating of at least 90
C.
2J-4. Remote Operation
The Hi-E
pool/spa heater controls can be wired
2
for remote operation. The Jandy AquaLink® RS
remote control permits switching from pool to spa,
with temperature set points for each, and turning the
heater on and off from a remote location. Contact
your local Jandy distributor for information on the
AquaLink RS control system to fi t your back yard
recreational needs.
An interrupt (on/off) type remote can be connect-
ed 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 temperature control panel or allow for temperature
adjustments.
To connect a 3-position remote switch (not
supplied by Jandy) to a Hi-E
harness assembly (Jandy part No. E0120000) which
connects to the temperature control panel. Installation
instructions are included with the wire harness assem-
bly. This type of remote will allow switching between
the "POOL", "SPA", and "OFF" function of the control
but does not allow for temperature adjustments.

2K. Water Piping
2K-1. Reversal of Water Connections
The Hi-E
is shipped with water con nec tions
2
on the right side, but it can be modifi ed in the fi eld to
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.
