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
installedatwaterlevelinthespa.
2. Plumb a three-port Intake Valve on the suction-side of the filter pump, so that center port of valve is
connectedtothepumpinlet.
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
throughthecenterport.
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)maybeprovidedtobypassthepoolreturnline. Thiswillenablesomeofthechemically-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
skimmerandmaindrainformaintenancepurposes.
Thisiseasilyaccomplishedbyinstallingamanualthree-portmixingvalveatthesuctionline.
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
motorizedtwo-portPoolCleanerValveatthisline. Themotorizedvalvewillautomaticallyopen
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.

CP-100 (OPTIONAL) INDOOR CONTROLLER
2 qty. separate 150 foot spools of 6-conductor 26 AWG communication cable are provided (one black and one silver)
to connect to the CP-100 Controller.
NOTE
Cable lubricant must be used when pulling these cables through the conduit.
Select a convenient location inside the house or other weather-protected area to mount the CP-100 Controller.
The overall width of the Controller (with doors open) is 11-½”. The location of the 6-conductor communication cables
(on the centerline of the enclosure) should therefore be at least 5-¼” from any door jamb, wall corner or other obstacle.
Remove backplate from Controller. Temporarily pull cables through large hole in backplate, and position backplate on
surface of wall. Make sure that backplate is level and that “TOP” nomenclature is oriented correctly, and mark the
three mounting points on the surface of the wall. With the backplate removed from the wall, drill 3/16” diameter holes
and insert mounting anchors (included) into the three holes. Pull cables through large hole in backplate, and use the
three 1-¼” screws to mount backplate to wall.
Use the Crimping Tool (model TOOL-6) to attach modular connectors at each end of both cables. See USING THE
CRIMPING TOOL, below.
At the CP-100 Controller, plug the silver cable (with modular connector attached) into the circuit board at Socket #1
(SILVER), and plug the black cable into Socket #2.
Use the four ½” screws (included) to mount CP-100 Controller to the backplate.
At the LX-100 RF Power/Load Center, it will be necessary to use two Cable Splitters (P/N 6CONDDUAL) to
connect to the Main circuit board. Disconnect the existing Receiver circuit board cables from the Main circuit board.
Plug the short cable (attached to single-connector end of each Cable Splitter) into the Power Center circuit board.
Plug Cable Splitters into Socket #1 (SILVER) and black Socket #2.
Paying careful attention to match cable color to socket cable color label (silver - silver), reconnect the existing Receiver
circuit board cables and the Indoor Remote cables into dual-connector end of each of the Cable Splitters.
Using the Crimping Tool
Make sure that the end of the cable is cut squarely (not diagonally).
Insert the cable between the stripper blades of the tool until it touches the stop. Squeeze the handles and pull the tool,
making sure that the cable stays perpendicular to it. If this is done correctly, the outer jacket of the cable will be
removed without damaging the insulation on the individual conductors.
Place a modular connector in the holder portion of the tool so that the front of the connector is against the stop and the
gold contacts face the crimper. Orient the prepared cable so that the blue conductor is closest to the tool handles, and
insert cable into connector. Make certain that the conductors are flush with the tip of the connector and directly under
the gold contacts. Squeeze the handles firmly to set the contacts and secure the cable.
Note
It is important that the orientation (blue conductor closest to tool handles) is identical at all four cable ends.

INTRODUCTION
The LX-100EZ is an electronic control system which is designed to coordinate and operate all of the equipment associated
with your swimming pool and spa.
The system is comprised of three principle components:
1. Hand-held Remote.
2. Power Center.
3. Motorized Valves (2 qty).
The Remote provides Push-button control of the equipment from the convenience of your fingertips; the LX-100 RF
Power/Load Center automatically controls the timing of your filter pump and pool cleaner (if applicable) and provides
easy maintenance for your Pool Serviceperson; and the Motorized Valves switch the filter and heater from pool to spa.
Additionally, the Control System incorporates important safety features which protect your pool equipment from accidental
damage.
Your system may also include additional Remote Controls and special options which further add to the convenience, safety
and economy of operating your pool equipment.
SAFETY FEATURES
HEATER PROTECTION
A built-in electronic delay circuit automatically runs the filter pump for an additional 4 minutes whenever the pool or spa
are turned off. This feature enables the heater to cool down, so that the heat exchanger and plumbing are not damaged
from overheating. Some heaters do not require a cool down cycle (i.e. MiniMax), therefore your installer may have turned
this feature off.
POOL CLEANER PROTECTION
If your system incorporates an automatic pool cleaner pump, it will have been plumbed in conjunction with the filter pump
so that it must have water circulation in order to operate.
The LX-100 RF Power/Load Center incorporates the following protection features against possible pump damage if there
is no water circulation:
1. The filter pump will automatically be activated whenever the pool cleaner pump is running, even if the filter
pump is not programmed on.
2. Your pool cleaner will automatically be switched off whenever water is being circulated to the Spa.
HAND-HELD REMOTE
CAUTION
The Hand-held Remote is not waterproof. If it accidentally gets submerged, disassemble by removing screw. Remove
battery and let unit dry out. Reassemble.
The Hand-held Remote will control four circuits.
Push-button “SPA” activates the Spa circuit.
Push-button “A” activates Auxiliary 1 circuit.
Push-button “B” activates Auxiliary 2 circuit.
Push-button “C” activates Auxiliary 3 circuit.
Each of the four functions on the hand-held remote has an "ON" and an "OFF" button.
IMPORTANT: When using the Hand-held Remote, it is necessary to hold the button down for a full one second
to insure that transmission takes place.
It is possible to incorporate a 30-minute or 90-minute countdown cycle for the Spa and/or Auxiliary 1 circuit (useful if
Aux1 is used for a jet pump or air blower). In this instance, whenever those circuits are turned on, they will automatically
shut down (at the end of the countdown cycle) without having to push the "OFF" button.
In order to incorporate the countdown feature, it is necessary to make adjustments to the circuit board located inside the
Receiver unit. See the Installation instructions.

LX-100 RF POWER/LOAD CENTER
Located in close proximity to your pool equipment, the LX-100 RF Power/Load Center houses mechanical time clocks
for your filter pump and pool cleaner (if applicable), and manual switches for your Pool Serviceperson.
FILTER PUMP and POOL CLEANER Time Clocks
Check with your Pool Builder or Service Company as to the amount of time required to provide efficient filtration and
cleaning of your pool.
To set the correct time of day, rotate the Dial(s) in a clockwise direction until the hours and minutes line up with the
white arrow at eight o’clock position on clock face.
Pay particular attention to the AM and PM sections of the Dial(s).
To program the daily filtration or cleaning cycle(s), depress the desired number of sections around the perimeter
of the Dial(s) by pushing towards the center. For each section depressed, the equipment will operate for 15 minutes.
NOTE
A built-in protection circuit automatically activates the filter pump whenever the pool cleaner is running, even
if the FILTER PUMP Time Clock is not programmed on. This safeguards against possible damage to the pool
cleaner pump when there is no water circulation.

The “OFF” position will disable the heater.
The “SPA & POOL” position will enable heating whenever the spa or pool is being circulated.
For Dual Thermostat Heaters: At the heater set pool and spa thermostats to desired temperatures. Verify at the
heater that the 3-position “ON/OFF” switch was set to “OFF” during installation.
For Single Thermostat Heaters: To heat the spa only set the spa temperature at the heater and set the LX-100 RF
Power/Load Center Heater switch to “SPA ONLY”. If pool heating is desired, it is necessary to turn the heater
thermostat down to pool temperature and set the LX-100 RF Power/Load Center Heater switch to “SPA & POOL”.
Verify at the heater that the “ON/OFF” switch was set to “ON” during installation.
PUMP DELAY Status Light
A built-in electronic delay circuit will automatically run the filter pump for an additional 4 minutes whenever the spa is
turned off. This enables the heater to cool down, so that the heat exchanger and plumbing are not damaged from
overheating. (See Heater Protection page 22.)
The PUMP DELAY Light indicates that the delay is in effect.
POWER ON Status Light
Indicates that power has been connected to the system.
If this light is not on, consult your Pool Serviceperson.

MAINTENANCE
CLEANING THE SPA
For cleaning or maintenance purposes, it is possible to use the Control System to automatically empty your spa and
then to refill with clean water from the Pool.
At the Power Center:
1. Set the SPA Service Switch to “DRAIN” position.
2. Set the FILTER Service Switch to the “ON” position. The Spa will begin to drain into the Pool.
3. Before the Spa has completely drained, set the FILTER Service Switch to the “OFF” position. Do not
drain the Spa completely or prime will be lost.
4. When cleaning or spa maintenance is complete, set the SPA Service Switch to the “FILL” position and
the FILTER Service Switch to the “ON” position. The Spa will begin to fill with clean water from the
Pool.
5. When the water level in the Spa has returned to normal, return theSPA Service Switch and the FILTER
Service Switch to the “AUTO” position.
CAUTION
Do not leave the equipment unattended when draining or filling the Spa.
WINTERIZING THE SYSTEM
During the winter season, it is possible to partially drain your Swimming Pool and disable the pool equipment, but still
be able to use your Spa.
Consult a qualified Service Company to drain the Pool and protect the plumbing from freeze damage.
The following procedure will disable the pool equipment:
1. With the Hand-held Remote, press Push-button SPA “ON” (to turn the Spa on).
2. At the motorized valves, flip toggle switch on rear of Valve Actuators to the “OFF” position.
3. With the Hand-held Remote, press Push-button SPA “OFF” (to turn the Spa off).
4. At the LX-100 RF Power/Load Center, set the FILTER Service Switch to the “OFF” position (to
disable the Time Clock) or, if daily Spa filtration is required, leave the FILTER Service Switchin the
“AUTO”positionandprogramtheFILTERPUMPTimeClockaccordingly.
If your Control System incorporates a Recirculating Freeze Sensor, it may not be necessary to winterize the pool.
It is however recommended that all Freeze Sensors be tested by an authorized Serviceperson before the onset of the
winter season.
Testing can be accomplished by placing the Sensor in a glass of ice water, and turning the FILTER Service Switch to
the “OFF” position. If the Sensor is functioning correctly, the filter pump should turn on within ten minutes. This test
should also be conducted on any Auxiliary Freeze Sensors which may have been added for the jet pump or auxiliary
equipment.
HAND-HELD REMOTE BATTERY REPLACEMENT
With normal use the battery should last for several years. In the event the battery must be replaced, slide the battery
cover from the bottom of the Hand-held Remote. Slide battery from retainer clip and discard in accordance with local
and/or state ordinances. Replace with 3V lithium battery number CR2032 or equivalent. Slide battery cover onto
remote and snap in place.
