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.
