IMPORTANT SAFETY PRECAUTIONS:
All wiring must be performed by a qualified electrician.
Basic safety precautions and local codes should be observed when
installing and using this electrical equipment.
EQUIPMENT LOCATION:
ALL ELECTRICAL EQUIPMENT MUST BE LOCA TED FIVE FEET OR
MORE FROM THE W A TER’S EDGE.
Select a convenient location to mount the LX-80 Control Center .
Wall-mount the LX-80, using appropriate screws through the three
external mounting points located on the side of the enclosure.
Do not drill and mount from inside enclosure.
Install to provide drainage of compartment for electrical components.

LX-80 CONTROL CENTER :
Loosen LOCK SCREW on hinged faceplate located in left-side of LX-80,
and swing open to expose the lo w voltage wiring compartment.
Pull low voltage cables through holes in bottom left-side of LX-80.
Strip wires ¼” and connect to circuit board at appropriate screw
terminals in accordance with low voltage wiring diagram located inside
enclosure cover .
NOTE:
terminal can be plugged from the circuit board without disconnecting wires.
For the conv enience of the serviceperson, the 10 position screw
RCS-1 SPA JETS SWITCH :
At the LX-80, connect 2-conductor cable form the Spa Jets Switch to
circuit board at REM 1 screw terminals.
At the Spa Jets Switch location, strip insulation of each wire ¼” and
connect to screw terminals #3 and #4 on switch contact block.
There is no polarity , so color-coding is unimportant.
Position gasket over back of switchplate, and mount to electrical box,
using mounting screws provided.
EMERGENCY SHUT-OFF SWITCH :
At the LX-80, connect 2-conductor cable for the Emergency Shut-off
Switch to circuit board at SHUT OFF screw terminals.
If model ESO-2 (with alarm) is being installed, connect green wire to the
upper screw terminal and red wire to the lower screw terminal.
If model ESO-1 is being installed, color-coding is unimportant.
At the Emergency Shut-off Switch, strip insulation of each wire ¼”, and
make appropriate connections to screw terminals #1 and #2 on switch
contact block:
For ESO-2, connect red wire to screw terminal #2 and green wire to
screw terminal #1, but do not disconnect factory wiring between
contact block and alarm.
For ESO-1, color-coding in unimportant.
Position gasket over back of switchplate, and mount to electrical box
using mounting screws provided.
CAUTION: If Emergency Shut-Off Switch is not installed, then a jumper
wire must be connected between “SHUT OFF” screw terminals on
circuit board.

FIREMAN’S SWITCH CONNECTIONS :
At the LX-80, connect 2-conductor cables from the P ool and Spa Gas
Heaters to circuit board at the appropriate screw terminals:
Connect Pool heater to POOL GHTR screw terminals, and Spa Heater
to SPA GHTR screw terminals.
Inside each gas heater (pool and spa), find fireman’s s witch wire nut, or
interrupt wire between thermostat and gas valve, and connect 2-conductor
cable with wire nuts, in accordance with wiring diagram.
Do not disconnect high limit and pressure switches.
CAUTION: If optional T emper ature Control Modules (model MOD-SOL) are
being used, heater thermostats must be overridden. To accomplish this , turn
thermostat switch to “ON”, “HIGH” or “SPA” (depending on the type of heater
used), and set dial to highest temperature possible.
LOW VOLT AGE WIRING:
3
HIGH VOL TAGE WIRING :
All high voltage connections are made to terminal blocks, which are
located behind service panel in right-side compartment of LX-80.
A wiring label is located adjacent to terminal blocks.
Knock-out holes are provided on bottom of enclosure for conduit mounting.
Install an electrical sub-panel with separate breakers for each load.
Provide a separate circuit breaker (if possible) to power the system.
Either 115V A C or 230VAC can be used. System dra ws less than 1 amp .
Run wires from circuit breaker to high voltage compartment of LX-80, and
connect to top terminal block which is marked “SYSTEM PO WER”.
Install 2 jumpers for 115V, or 1 jumper for 230V wiring, according to
wiring label.
Provide independent circuit breakers (if possible) f or R1 (POOL FL TR),
R2 (SP A FLTR) and R3 (JETS 1).
Run wires from breakers to high voltage compartment of LX-80, and
connect to LINE 1 and LINE 2 terminals of appropriate terminal block.
Connect pumps and other high voltage equipment to LOAD 1 and LOAD 2
terminals at appropriate terminal block.
Each individual terminal block can be wired for either 115VAC or 230V A C.
For 115V equipment, only half of the terminal block will be used.
CAUTION: If pumps exceed 2½ HP, the high voltage relay should be
used to energize a magnetic starter.
NOTE: Circuits for R4, R5, R6, and R7 are optional and require additional
relay kits (model RLY-LX).
A Relay Allocation Chart is provided inside enclosure cover for the
serviceperson’s con venience.
To reduce the risk of electric shock, provide a continuous green insulated
copper wire, no smaller than #12AWG, betw een grounding bus of LX-80
and grounding terminal of electrical supply panel.
Additionally , a wire connector is provided f or bonding to local ground
points, To further reduce the risk of electric shock, this connector should
be bonded with a #8AWG copper wire to any metal ladders , water pipes,
or other metal within five feet of the pool or spa.

SYSTEMS OPTIONS
TEMPERATURE CONTROL MODULES :
It is possible to provide precision thermostatic control of the pool and
spa heaters by adding T emperature Control Modules (model MOD-SOL)
at the LX-80. A separate Module should be pr ovided for each heater .
Additionally , each Module contains a b uilt-in solar control for the optional
control of a booster pump or motorized valve, or both. This enables a
separate solar system for each body of water .
Install MOD-SOL in accordance with instructions provided.
MULTIPLE SPA JET PUMPS OR BLOWERS :
The standard system is provided with a relay to activate one jet pump or
air blower . Howev er , a combination of up to 4 jet pumps and / or air
blowers can be controlled by the Spa Jets Switch. A separate relay
(model RLY-LX) should be added for each pump.
Install RLY-LX in accordance with instructions provided.
A second JETS 1 relay socket is provided on the circuit board.
If more that 2 pumps are being used, install an adapter (model RYA-LX)
in which to plug two relays from one relay socket.
DUAL REMOTE CONTROLS :
A second Spa Jets Switch (model RCS-1) may be added to the system to
activate up to 2 more pumps.
Install RCS-1 in accordance with previous instructions, and connect
2-conductor cable to LX-80 circuit board at REM 2 screw terminals.
Additonal relays (model RLY-LX) should be installed for each pump .
Plug RLY-LX into LX-80 circuit board at JETS 2 relay socket(s).
POOL CHLORINE PUMP :
A pool filter pump is less than 2HP, the POOL FLTR relay (R1) can be
used to actuate a separate chlorine pump.
If pool filter pump is 2HP to 2½HP, a separate rela y (model RLY-LX)
should be used to actuate the chlorine pump.
Install RLY-LX in accordance with instructions, and plug into circuit board
at POOL ORP relay socket.
SPA CHLORINE PUMP :
If spa filter pump is less than 2HP, the SPA FLTR relay (R2) can be used
to actuate a separate chlorine pump.
If spa filter pump is 2HP to 2½HP, a separate rela y (model RLY-LX)
should be used to actuate the chlorine pump.
Use an adapter (model RYA-LX) in order to plug both relays into the
circuit board at SP A FLTR relay socket.
