Service Voltage:
120 Volt (Plug & Play Spas): Typically equipped with a 15A GFCI power cord, going to a dedicated household outlet. 110V, 115V, 120V call-out ratings are used interchangeably.
240 Volt (Hard Wired Spas): Connected to a nearby GFCI protected disconnect box on a 50A or 60A circuit as required. 220V, 230V, 240V call-out ratings are used interchangeably.
Heater Wattage Choice:
A heater's wattage rating is the amount of electrical energy (in kilowatts) it consumes while warming the water @ a given voltage.
4kW@240V (1kW@120V): Draws less amperage. Most Common.
5.5kW@240V: Faster heating - Maintains temp in colder climates. For 50A + service.
Jet Pump 1:
120V or 240V - Single OR 2-speed pump - 13 Amps max
Voltage: Verify on motor label. 120V may be called-out as 110V or 115V. Similarly, 240V may be 220V or 230V.
Speeds: Two speed pumps list 2 amperage & RPM ratings - High/Low speed. Single speed pumps only list 1 amperage & RPM rating.
ProTip: Two speed pumps require 4-wire cords, while 1-speed pumps need only 3.
Pump 2:
120V or 240V - Single speed pump - 13 Amps max
Voltage: Verify on motor label. 120V may be called-out as 110V or 115V. Similarly, 240V may be 220V or 230V.
Speeds: Single speed pumps only list 1 amperage & RPM rating.
ProTip: Single Speed pumps use a 3-wire cord.
Note: Don't have a second pump? Choose Not Applicable.
Blower:
120V or 240V - Single speed air blower - 8 Amps max
Blower: Pushes air through dedicated air-lines, creating fine bubbles.
Voltage: Verify on label. 120V may be called-out as 110V or 115V. Similarly, 240V may be 220V or 230V.
Speeds: Blowers only list 1 amperage & RPM rating.
Note: Don't have a blower? Choose Not Applicable.
Ozonator:
120V or 240V - 2 Amp max
Voltage: Many newer ozonators operate on a range of voltages, such as 100 thru 240V. Others may have fixed voltages. Verify on ozonator label.
IMPORTANT: Ozonator voltage must coincide with Jet Pump 1.
Pro Tip: Ozonators usually last 3 or 4 years. Replace aging ozonators with a Clarathon Hi-Output Spa Ozonator Kit.
Note: If you don't have an ozonator, take this opportunity to add one, or choose Not Applicable.
