Power Supply Requirements
0 Series Altamar, Cameo, Majesta, Marin, Optima Models
(See Page 18 for 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 not operate while both jets pumps are running.
Alternate 0 Amp -Wire Power Configuration
(For Homes Where 0V/0A or 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)
• Number of Wires: Three - Copper Only (Red, Black, Green)*
• Max Spa Current Draw: 26 Amps
If the household’s electrical service does not have the full 240V/50A power available, the spa may be connected to 240V/40A service if a minor circuit
board modification is performed by your qualified technician. In this configuration, the heater will yield the same rapid temperature increase as in 50A
operation but
will not operate while either jets pump is running or when the air blower is running.
Alternate 0 Amp -Wire Power Configuration
(For Maximum Heater Performance)
• Required Voltage: 240 VAC (2 Hots, 1 Ground); See diagram page 9.
• Required GFCI Breaker: 60 Amp Dual-pole (Hard Wired Only)
• Number of Wires: Three - Copper Only (Red, Black, Green)*
• Max Spa Current Draw: 48 Amps
In this configuration, the heater will operate while both jets pumps and the blower are running. This may be preferable for owners of spas in cold
climates because it will help the spa maintain water temperature during use.
*All models: wire size must meet NEC recommendations and is determined by maximum current draw and length of run.
