Sundance Spas Spas 880 Series - Manual (Page 20)

important: All of the alternative electrical configurations require
a qualified technician to perform minor circuit board modifications. To avoid
damage to the spa, do not activate power to the spa until these modifications
have been made. We recommend Square-D or Cutler Hammer circuit breakers.
Power Configurations for 680 denali and Tacoma Models (North
America, 60Hz)
This section describes the three power configuration choices (Standard 15 Amp,
Alternate 30 Amp, or Alternate 40 Amp) for Denali and Tacoma hot tub models.
Config. #1
Standard 15A Configuration
(factory setting)
120 VAC/15A • 3-wire configuration
(hot, neutral, and ground)
1 kW heater output
•
Use either the 15A GFCI power •
cord (supplied only for US
models) or a 15A single-pole
GFCI breaker (not supplied)
Maximum electrical current draw
•
of 12A
In this Standard 15A configuration, the heater
does not operate if the high-speed jets pump is
activated.
Place the spa within 10 ft (3m) of a dedicated
grounded, grounding-type electrical outlet so
that the power cord supplied with the spa can
be plugged directly into it. Use the power cord
shipped from the factory. Using another power
cord may cancel the warranty.
If the spa is more than 10 ft (3m) from an
outlet, it must be hard wired to a 15A single-
pole GFCI breaker.
Config. #2
Alternate 30A Configuration
240 VAC/30A 4-wire configuration •
(2 hots, neutral, and ground)
4 kW heater output
•
30A dual-pole GFCI breaker (not •
supplied)
Maximum electrical current draw
•
of 21A
If your home does not have 240 VAC/40A
power available, connect the spa to a 240
VAC/30A power source. Then, have a qualified
electrician modify the circuit board to match
the power source.
In this configuration, the heater yields the
same rapid temperature rise as in the 40A
configuration. However, the heater does not
operate at the same time the high-speed jets
pump is operating.
Config. #3
Alternate 40A Configuration
240 VAC/40A 4-wire configuration •
(2 hots, neutral, and ground)
4 kW heater output
•
40A dual-pole GFCI breaker (hard •
wired only)
Maximum electrical current draw
•
of 30A
In the Alternate 40A configuration, the heater
does operate at the same time the high-speed
jets pump is operating. It is necessary to have
a qualified electrician modify the circuit board.
Note
Wire size must meet NEC recommendations and is determined by
maximum current draw and length or run.
