ELECTRICAL INSTALLATION
Equipment Access
To access the electrical equipment system in your spa the Eco-wood or
natural cedar slats and panel must be removed. The panel below the
topside control is typically the one to remove to access the equipment.
(Actual slat and screw locations will vary depending on the spa model)
120 VOLT INSTALLATION
For spas with a Control Unit designed to operate at 120V, 60Hz. Installation of a 20 amp dedicated circuit is
required. The unit may be connected to this dedicated circuit with a 15 amp Ground Fault Circuit Interrupter
(GFCI) cord either installed at the factory or supplied by your local Columbia Spas dealer. All National and Local
electrical codes must be observed.
The GFCI cord should be tested before each spa use to insure that it is functioning properly.
240 VOLT INSTALLATION
For spas with a Control Unit designed to operate at 240V, 60Hz. Installation of a 50 amp dedicated circuit is
required. The unit must be hard wired directly to a supply circuit using 6 AWG copper that is protected by a
Ground Fault Circuit Interrupter (GFCI) circuit breaker.
General Electrical Instructions (240V only – see reference diagram below)
This hot tub must be permanently connected (hard-wired) to the power supply.
No plug-in connections
or extension cords are to be used in conjunction with the operation of this hot tub.
Supplying
power to the hot tub which is not in accordance with these instructions will void both the independent
testing agency listing and the manufacturer’s warranty.
The power supplied to this hot tub must be a dedicated circuit with no other appliances or lights sharing
the power provided by the circuit.
All wiring must be copper to ensure proper connections.
Do not use aluminum wire.
When using wire
larger than #6, add a junction box near the hot tub and reduce to short lengths of #6 wire to connect to
the hot tub.
The disconnecting means must be readily accessible to the hot tub’s location but installed at least 5 feet
(1.5m) from hot tub water.
The electrical circuit supplied for the hot tub must include a suitable ground fault circuit interrupter (GFCI)
as required by NEC Article 680-42.
A green-colored terminal or a terminal marked G, GR, Ground, Grounding, or the symbol is located inside
the supply terminal box or compartment. To reduce the risk of electrical shock, this terminal must be
connected to the grounding means provided in the electric supply service panel with a continuous copper
wire equivalent is size to the circuit conductors supplying this equipment.
At least two lugs marked BONDED LUGS are provided on the external surface or on the inside of the
supply terminal box or compartment. To reduce the risk of electric shock, connect the local common
bonding grid in the area of the hot tub or spa to these terminals with an insulated or bare copper
conductor not smaller than 6 AWG.
All field-installed metal components such as rails, ladders, drains, or other similar hardware located 3 m
of the spa or hot tub shall be bonded to the equipment grounding bus with copper conductors not smaller
than 6 AWG.
IMPORTANT NOTICE:
The electrical wiring of this hot tub must meet the requirements of the
National Electrical Code (NEC) and any applicable state or local codes. The electrical circuit must be
installed by a qualified electrician and approved by a local building/electrical inspection authority.
