Power Supply Requirements
0 Capri Models
Important: Your qualified technician must perform minor circuit board modifications when either models’ alternate electrical configuration
is used. To avoid damage to the spa, do not activate power until circuit board modifications have been made. We recommend Square-D or
Cutler Hammer Breakers.
Standard 0 Amp -Wire Power Configuration
(Factory Setting)
• Required Voltage: 240 VAC (2 Hots, 1 Ground); See diagram page 9.
• Required GFCI Breaker: 50 Amp Dual-pole (Hard Wired Only)
• Number of Wires: Three - Copper Only (Red, Black, Green)*
• Max Spa Current Draw: 40 Amps
In 50A configuration, the heater will operate while the jets pump and air blower are running.
Alternate 0 Amp -Wire Power Configuration
(For Homes Where 0V/0A Power Is Unavailable)
• Required Voltage: 240 VAC (2 Hots, 1 Ground); See diagram page 9.
• Required GFCI Breaker: 40 Amp Dual-pole (Hard Wired Only)

In this configuration, the heater will yield the same rapid temperature increase as in 50A operation but will not operate while the jets pump or air blower is
running.
*All models: wire size must meet NEC recommendations and is determined by maximum current draw and length of run.
