Compool Pool-Spa Switching System CP30 User manual

SYSTEM START-UP
Apply power to the system.
At the LX-30 Power Center, check that the POWER Status Light has turned on.
If the status light is not on, check the 3 amp circuit breaker which is located above
the faceplate. Tripped circuit breaker is indicated by a white tab. Pushto reset.
Turn the FILTER PUMP Service Switch "ON" and "OFFto verify that pump is
operating.
Return FILTER PUMP Service Switch to"TIMER" position, and activate filter
7ump usingthe FILTER TIMER Dial.
t the system incorporates a pool cleaner pump, activate pump using the
CLEANER TIMER Dial.
At the Remote Control, turn SPA Switch to "SPA position.
Check that Valve Actuators have rotated to correct positions. If either valve is
180" out of phase, flip toggle switch on rear of Valve Actuator from "ON1" to
"ON2" position.
Turn HEATSwitch to "SPA position, and check that heater has been activated.
Turn AUXl and AUX2 Switches "ON", and verify that auxiliary equipment has
been activated.

INSTALLATION INSTRUCTIONS
CP30 POOL-SPA SWITCHING SYSTEM
IMPORTANT SAFETY INSTRUCTIONS
All wiring must beperformed by a qualifiedelectrician.
Basic safety precautionsand local codes should
always befollowed when installingand usingthis
electrical equipment.
READAND FOLLOW ALL INSTRUCTIONS.
WARNING : To reducethe risk of injury,do not
permit children to usethis product unlessthey are
closely supervised at all times.
SAVE THESE INSTRUCTIONS.

SYSTEM OPTIONS RECOMMENDED HYDRAULIC SCHEMATIC
POOL CLEANER :
Forsystemswhich incorporateabooster pump poolcleaner, it ispossibleto adda
mechanicaltime clock for programmingthe daily cleaning cycles.
Install24-Hour Time Clock (modelTMR-LX) into LX-30faceplate at the
CLEANER TIMER location,and plug into circuit board at CLNR TIMER socket, in
accordancewith instructions provided.
Installa Relay Kit (model RLY-LX) at the LX-30Power Center in accordance
with instructionsprovided, and plug into circuit board at CLNR relay socket.
NOTE
: Itwill not be possibletoactivate the pool cleaner unlessthe CP-30
Remote Control has been connected.
SPA WATERFALL CONTROL :
For systemswhere spa water level is higher than that of the pool, it is possibleto
use either AUXl or AUX2 Switches at the Remote Control to rotate the return
valve to spa return position.
This creates an overflow (waterfalleffect) from the spa intothe pool, while the
system is in "pool mode". The effect will, however, cease whenever the system is
in"spa mode".
To enablethis feature, install a Spa Waterfall Control (model RLY-WTRFL) at
the LX-30 Power Center in accordancewith instructions provided.
FREEZE PROTECTION :
A RecirculatingFreeze Sensor (model FPS-C) may be added to the system. It
will protectthe plumbing and equipmentfrom possible freeze damage by running
the filter pump whenever the temperaturefalls to approx. 41°F.
Install FPS-C in accordancewith instructions provided, and connect to circuit
board at FRZ and GND screw terminals, in accordance with wiring diagram.
An Auxiliary Freeze Sensor (model FPS-AUX) may also be added to activate
auxiliary equipment (such as ajet pump) during potential freezing conditions.
Install FPS-AUX in accordancewith instructions provided.
NOTE
: Itisadvisable toinspect andtest the freeze sensor(s) at least once
a year, preferably priortothe onset of the freezing season. Testing can be
accomplished byimmersing sensor inicewater.

EQUIPMENT LOCATION HIGH-VOLTAGE WIRING
Select a convenient location to install the various components of the System.
All electrical equipment must be located five feet or more from the water's edge
:
1. LX-30 PowerCenter at the equipment site.
2. CVA-24 Valve Actuators at valves to be motorized.
3. CP-30 Remote Control at convenient location indoors or outside.
POWER CENTER
Select a convenient location (at the equipment site) to mountthe LX-30 Power
Center. Ensure that the location is greater than 5 feet from the water's edge and
no further than 15feet from any motorized valves (otherwiseValve Actuator cable
will needto be extended).
Mountthe LX-30on a flat surface using appropriate screws through the three
external mounting points located on the side of the enclosure.
Do not drill and mount from insidethe enclosure.
Install to provide drainage of compartment for electrical components.
LOW-VOLTAGE CABLES
Determine lengths of low voltage cable needed between Power Center andthe
various pieces of equipment.
1. 4-pair 22AWG cable to CP-30 Remote Control.
2. 3-conductor 22AWG cable to dual-thermostat gas heater (if applicable).
3. 2-conductor 22AWG cable for fireman's switch connections (if applicable)to
dual-thermostat gas heater.
4. 2-conductor 22AWG cable to single-thermostat gas heater (if applicable).
5. 2-conductor 14AWG cable to electric heater (or heat pump).
6.
CVA-24 Valve Actuators are provided with 15 feet of 3-conductor cable.
Install cable, using plastic or metallic conduit where cables run underground,
through concrete, etc.
NOTE: Never installlowvoltage and highvoltage wires inthe same conduit.
It isadvisableto maintaina minimum distance of 12" between parallel runs
of lowvoltage andAC current-carrying wires.
GENERAL :
At the equipment site, install an electrical sub-panel with separate breakersfor
each load.
Make sure that the motor(s)on the equipment have built-inthermal protection.
All highvoltage connections are madetoterminal blocks, which are located
behindservice panel inright-side compartment of LX-30 Power Center.
A highvoltagewiring label islocatedadjacent toterminal blocks.
Knock-out holes are provided on bottom of enclosure for conduit mounting.
To reduce the risk of electric shock, provide a continuous green insulated copper
wire, no smaller than #12 AWG, between grounding bus of LX-30and grounding
terminal of electrical sub-panel.
A wire connector is provided for 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, pipes, or other metal within five feet of the spa.
SYSTEM POWER :
Provide a separate circuit breaker to power the system.
Either 115 or 230V AC can be used (115V is preferable). System draws lessthan
1amp.
The circuit breaker should be readily accessible to the spa user, but installed at
least 5 feet from the water's edge. The breaker will open all ungrounded supply
conductors to comply with section 422-20 of the National Electrical Code, ANSI/
NFPA 70-1987.
Run wires from circuit breaker to high voltage compartment of LX-30,and connect
to top terminal block, which is marked "SYSTEM POWER".
Install2 jumper wires for 115V, or 1jumper for 230V, according to wiring label.
EQUIPMENT POWER :
Provide independent circuit breakers for R1 (FLTR), R2 (AUXl),and R3 (AUX2).
Run wires from breakers to high voltage compartment of LX-30,and connect to
LlNE 1and LlNE 2 of appropriate terminal blocks. Connect pumpsand other high
voltage equipment to LOAD 1and LOAD 2 terminals at appropriate terminal
blocks.
Each individual terminal block can be wired for either 115V or 230V AC.
For 115V equipment, only half of the terminal block will be used (ie: LlNE 1and
LOAD 1).
If power relaysare being usedto control underwater lighting fixtures, a GFCl
should be provided. The conductors on the load side of the GFCI must not
occupy conduit, boxes or enclosures containing other conductors unless the
additional conductors are also protectedby a GFCI.

VALVE ACTUATORS LOW-VOLTAGE WIRING
Mount Valve Actuators (model CVA-24) to three-port valves in accordance with
instructionsprinted on box.

circuit board at appropriate valve socket
:
1. Intake (suction) Valve to INT VLV socket.
2.
ReturnValve to RET VLV socket.
3. Auxiliary Valve (optional) to AUX VLV socket.
Coil any excess cable, and carefully store inside low voltage compartment.
