Important Safety instructions
1. Read all instructions before installing this spa equipment
system.
2. Danger – A wire terminal marked “ground” is provided within the
power box (Ill. 1, Item 13). To reduce the risk of electrical shock,
connect this terminal to the grounding terminal of your electrical
supply panel with a continuos green insulating copper wire equivalent
in size to the circuit conductors supplying this equipment, but no
smaller than No. 8 AWG.
3. Danger – Risk Of Electrical Shock. Install at least five feet from spa.
(This equipment system may be installed within five feet of the spa if,
in accordance with the National Electrical Code, ANSI/NFPA 70-1990,
each metal surface is permanently connected by a No. 8 AWG copper
conductor attached to the wire connector on the terminal box provided
for this purpose – Ill. 1, item 4.)
4. CAUTION – This equipment system must be hardwired to the
household electrical service box only. Do not use an extension cord or
any other disconnectable power cord. The use of an extension cord or
a disconnectable power cord is highly dangerous and will void all
warranties.
5. This equipment system must be installed in such a manner as to
provide drainage of casual water, such as rainwater, away from all
electrical components.
6. The electrical supply for this product must include a suitably rated
switch or circuit breaker to open all ungrounded supply conductors to
comply with Section 422-20 of the National Electrical Code, ANSI/NFPA
70-1990.
7. The electrical circuit supplied for the spa must include a suitable
ground fault circuit interrupter (GFCI) as required by NEC Article 680-
42.
8. READ AND FOLLOW THE OWNER OPERATING INSTRUCTIONS
PROVIDED BEFORE USING THE SPA.
9. SAVE THESE INSTRUCTIONS.

Where To Place The Equipment System
The equipment system must be located within forty (40)-running feet
of the spa. If an existing gas heater is to be used, this equipment
system should be placed near the gas heater.
If the equipment system is to be installed above the spa’s normal
water level, it will require the available strainer pot housings to help
achieve prime. Order and install two each of part numbers 6472-619,
6560-006, and 6560-004.
The equipment system base should not be set on the ground. A
separate concrete pad is preferred, but any platform which serves to
permanently keep the system from contact with the ground is
acceptable. Do not install the equipment system in a depression where
casual water may stand after a rain or lawn sprinkling.
If the equipment system is to be exposed to direct sunlight and you
are in a hot climate, you will need to shade the equipment system to
protect it from the excessive temperatures of the mid-day sun.
Connecting Pipes Between Spa And
Equipment
Water piping between the spa and the equipment system should be 2”
diameter or larger Schedule 40 PVC or heavier. The use of 90 degree
elbows should be minimized. Instead use two 45 degree elbows or,
better still, gradual flex hose sweeps to make turns when possible.
The pipes on the Sundance spa shell are color coded. Connect the
equipment components to these pipes as follows:
Dual-speed Pump-Suction----------Red
Dual-speed Pump- Discharge-------Blue
Single-speed Pump-Suction---------Orange
Single-speed Pump-Discharge-------Yellow
Air Blower-----------------------------Green
Check with the local Building Department to ensure that your planned
installation meets the code requirements.

Blower Loop—If the equipment system is installed at a level lower
than the maximum water level of any spa besides a Sundance spa,
measures must be taken to keep water from backing up into the air
blower. When connecting the pipe from the air blower to the spa, route
the pipe so that it rises at least 12 inches above the maximum water
level of the spa. This raised “loop” can be located anywhere between
the spa and the air blower, however, it is generally preferable to locate
it as close to the spa as possible. Do not plan to rely on a check valve
as sole protection against water back up as they can fail over time.
(NOTE: This loop is not required on Sundance spas because they
contain built-in protection against the possibility of water backing up
into the air blower.
Isolation Valves—In cases where equipment is below the water
level, consider installing valves in the water pipes on both the suction
and discharge sides of the equipment system so that the system can
be isolated for serving without draining the spa.
Drain Valve—The simplest method for the spa owner to employ
periodic draining the spa is to use a submersible pump. However, for
the owner’s convenience, some installers install a valve or valves on
the discharge side of the single-speed pump to provide a means of
draining the spa.
IMPORTANT: Provide specific instructions to the owner regarding
proper draining procedures.

Electrical Installation Instructions
1. This spa equipment system 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
equipment system. Supplying power which is not in accordance with
these instructions will void the manufacturer’s warranty.
2. The power supplied to this equipment system must be a dedicated
circuit with not other appliances or lights sharing the power
provided by the circuit.
3. All electrical work must be done to National Electrical Code (NEC)
and any other applicable electrical codes.
4. The electrical circuit must be installed by a qualified electrician and
checked by a local building/electrical inspection authority.
5. The electrical circuit supplied for the spa must include a suitable
ground fault circuit interrupter (GFCI) as required by NEC Article
680-42.
6. Determine the current, voltage and wire size required. Refer to the
table titled “Power Supply Requirements” (Ill. 2) for current and
voltage required. Select wire type and size based on the power
requirements and the length of electrical run per National Electrical
Code requirements. (Note: When using wire larger than #6, add a
junction box near the equipment system and reduce to short
lengths of #8 to connect to system.)
7. All wiring must be copper to ensure reliable connections. Do not use
aluminum wire.
8.To gain access to the main terminal connection for the spa
equipment system, remove the front cover of the control box.
9. Using a connector feed the cable through the opening provide on
the bottom of the control box (Ill. 1, item 2).
10. Connect wires, color to color, on the terminal strip (Ill.
1, item 13). TIGHTEN SECURELY! All wires must be
hooked up. Do not neglect to run the ground line as
serious damage could result.

Power Supply Requirements
The power supply required by the equipment system depends on
certain variables as indicated in the table below. Note that these
requirements are for the equipment system only. Power for an
external electric heater, if used, must be separate from, and in
addition to, the power supplied to the equipment system. For gas
heaters, add the power requirements to these figures.

If the home’s electrical service does not have the full 50A, 240V power
available, the spa may be connected to 30A, 240V service if a minor
circuit board modification is performed by the dealer. In this
configuration, the heater will yield the same rate of temperature
increase as in 50A operation, but will not operate while the high speed
of either pump or the air blower is operating. This could result in rapid
cooling of the water while the spa is being used during periods of cold
ambient temperatures.
*In 50A configurations, the heater will not operate while both pumps
are operating at high speed.
