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 Power Center 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 mount the LX-30 Power
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 cable
will need to be extended).
Mount the LX-30 on 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 inside the enclosure.
Install to provide drainage of compartment for electrical components.
LOW-VOLTAGE CABLES Determine lengths of low voltage cable needed between Power Center and the
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 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.
GENERAL
:
At the equipment site, install an electrical sub-panel with separate breakers for
each load.
Make sure that the motor(s) on the equipment have built-in thermal protection.
All high voltage connections are made to terminal blocks, which are located
behind service panel in right-side compartment of LX-30 Power Center.
A high voltage wiring label is located adjacent to terminal 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-30 and 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 #8 AWG 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 11 5 or 230V AC can be used (1 15V is preferable). System draws less than
1 amp.
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/
N FPA 70- 1 987.
Run wires from circuit breaker to high voltage compartment of LX-30, and connect
to top terminal block, which is marked "SYSTEM POWER".
Install 2 jumper wires for 115V, or 1 jumper 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 1 and LlNE 2 of appropriate terminal blocks. Connect pumps and other high
voltage equipment to LOAD 1 and LOAD 2 terminals at appropriate terminal
blocks.
Each individual terminal block can be wired for either 1 15V or 230V AC.
For 115V equipment, only half of the terminal block will be used (ie: LlNE 1 and
LOAD 1).
If power relays are being used to 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 protected by a GFCI.
