EQUIPMENT LOCATION
With the exception of the optional Spa-side Remote Control (which is ETL listed for installation right at the
tile-line of the spa), all equipment must be located five feet or more from the water’s edge.
1. LX-100 RF Power/Load Center at the equipment site.
2. Valve Actuators at valves to be motorized.

PLUMBING REQUIREMENTS
Plumb system in accordance with “RECOMMENDED HYDRAULIC SCHEMATIC” on page 6, local codes
and the following guidelines.
Bring all lines back to the equipment pad.
1. Spa should be at or above the level of the pool.
If spa is attached to pool, provide a dam between the two bodies of water to allow spa overflow into
pool. If spa is not attached to pool, an overflow, sufficient in size to carry full pump-flow, must be
installed at water level in the spa.
2. Plumb a three-port Intake Valve on the suction-side of the filter pump, so that center port of valve is
connected to the pump inlet.
Connect spa suction to one side of Intake Valve, and pool suction to the other side.
3. Plumb a three-port Return Valve on the return-side of the heater, so that return water will enter valve
through the center port.
Connect spa return to one side of Return Valve, and pool return to the other side.
4. A ½” spa make-up line (incorporating a ½” manual gate or ball valve and, for elevated spas, a ½” check
valve) may be provided to bypass the pool return line. This will enable some of the chemically-balanced
water from the pool to cycle through the spa. The manual valve will allow the amount of bypass to be
adjusted.
5. If the spa is to be constructed in concrete, special provision should be made at this time for the installation
of the optional Spa-side Remote Control.
Select a convenient location in the deck or above water level in the spa wall (where the Spa-side Remote
will not be submerged by the spa water), and install a 6” to 12” length of 1-½” PVC pipe to provide a
receptacle for the Spa-side Remote. The pipe should be level and protrude beyond the finished surface of
the spa. It will be cut back at a later date.
Reduce pipe size down to ½” or ¾” conduit, and run to proposed LX-100 RF Power/Load Center
location at equipment pad. Use sweep elbows for turns.
The Spa-side Remote will not be installed until spa construction is complete.
6. For systems which incorporate a skimmer, it is possible to balance the amount of suction between the
skimmer and main drain for maintenance purposes.
This is easily accomplished by installing a manual three-port mixing valve at the suction line.
Plumb one port to the skimmer and the other to the main drain.
7. If a “non-booster pump” pressure-side pool cleaner is being used, plumb a manual three-port valve
between the filter pump and filter, with the third port plumbed to the pool cleaner line, and install a
motorized two-port Pool Cleaner Valve at this line. The motorized valve will automatically open
whenever the Control System activates the pool cleaner.
8. If a booster pump pool cleaner is being used, plumb the booster pump so that its suction-side is
connected to the pool return, after the heater and as close to the ground as practical.
9. If optional water sensor is used with Cp-100 indoor controller, locate between filter pump and filter.

LX-100 RF POWER/LOAD CENTER
Select a convenient location to mount the LX-100 RF Power/Load Center. Ensure that the location is greater than
5 feet from the water’s edge and no further than 15 feet from any motorized valves (otherwise Valve Actuator cables
will need to be extended). The top of the LX-100 RF Power/Load Center should be a minimum 5 feet above the
ground and a minimum 8 feet from any air blower to optimize RF signal reception.
Mount the LX-100 RF Power/Load Center on a flat surface using appropriate screws through the external mounting
points located on the side of the enclosure. Do not drill and mount from inside the enclosure.
Loosen LOCK SCREW of hinged faceplate in left-side of LX-100 RF Power/Load Center, and swing open to expose
the low-voltage compartment. All low-voltage connections are made to the circuit board, in accordance with wiring
diagram located inside door.
The high-voltage wiring compartment is located behind service panel in right-side of LX-100 RF Power/Load Center.
HIGH VOLTAGE WIRING
GENERAL
If using a LX-100EZT System, install an electrical sub-panel with separate breakers for each load at the equipment site.
Circuit breakers should be readily accessible to the spa user, but installed at least 5 feet from the water’s edge.
If using a LX-100EZTL System, the LX-100 RF Power/Load Center has provisions for breakers.
Make sure that the motor(s) on the equipment have built-in thermal protection.
At the LX-100 RF Power/Load Center, remove the service panel (at right) to expose the high-voltage compartment,
and knock-out the appropriate holes at bottom of enclosure to facilitate conduit mounting. Screw terminals are
provided for high-voltage connections.
SYSTEM POWER
Provide a separate circuit breaker to power the system. Either 115 or 230 VAC can be used (115V is preferable).
System draws less than 1-Amp. The breaker will open all ungrounded supply conductors to comply with section
422-20 of the National Electrical Code, ANSI/NFPA 70-1987.
Run appropriate wires from circuit breaker to high-voltage compartment of LX-100 RF Power/Load Center, and
connect to top terminal block in accordance with wiring label, which is marked SYSTEM POWER.
Install two jumper wires for 115V, or one jumper for 230V, according to wiring label.
EQUIPMENT POWER
Provide independent circuit breakers for R1 (FLTR), R2 (AUX1), R3 (AUX2) and R4 (AUX3).
Run appropriate wires from breakers to high-voltage compartment of LX-100 RF Power/Load Center, and connect to
LINE1 and LINE2 screw terminals at each terminal block.
Connect pumps and other high-voltage equipment to LOAD1 and LOAD2 terminals.
Each individual terminal block can be wired for either 115V or 230VAC.
Note:
For 115V equipment, only half of the terminal block will be used (i.e.: LINE1 and LOAD1).
P/N 520050 8 Rev. F 3-26-04
LOW VOLTAGE CABLES
Install cable between the low voltage compartment of the LX-100 RF Power/Load Center and the various pieces of
equipment. Provide plastic or metallic conduit where cables run underground, through concrete, etc.
Note
Never install low voltage and high voltage wires in the same conduit. It is advisable to maintain a
minimum distance of 12” between parallel runs of low voltage and AC current-carrying wires.
Valve Actuators are provided with 15 feet of 3-conductor cable.

RECEIVER CIRCUIT BOARD
Mounted to the back of the LX-100 RF Power/Load Center is the Receiver Circuit Board.
On the circuit board, you will discover the following:
1. A 4-position configuration switch (designated S2), which can be used to configure an automatic
countdown cycle for the Spa and/or the Aux1 circuit. (Aux1 is designated as button “A” on Hand-held
Remote). See page 13 for details.
2. A 10-position configuration switch (designated S1), which can be used to customize the communication
link between the Receiver and Hand-held Remote.
3. 2-qty. status lights (designated POWER and COMMAND), which are used for trouble-shooting:
POWER: Indicates that the Control System is supplying power to the Receiver unit.
COMMAND: Flashes whenever a button is pushed on the Hand-held Remote.
