SELECTING THE VOLTAGE FOR YOUR SPA
These spas are designed to operate at 230 volts, 60 Hz. When these spas are connected to 230 volts, the heater will provide approximately 4000 watts of heat when the
pump is operating in LOW or HIGH speed and the thermostat is calling for heat.
All electrical connections must be made in accordance with the wiring information
contained in the electrical control box or on the back of the field wiring access panel of the equipment module.
230 VOLT PERMANENTLY CONNECTED
When using 230 volt power supply, installation of a 50 amp dedicated circuit is required. Your spa must be hardwired direct to a GFCI-protected subpanel by a licensed
electrician. A wiring diagram is provided inside the equipment module showing where the connections are to be made.
ELECTRICAL REQUIREMENTS AND PRECAUTIONS
Your spa has been carefully designed to give you maximum safety against electrical shock. Connecting the spa to an improperly wired circuit will negate many of the
spa’s safety features. Improper wiring may also cause electrocution, risk of fire, and other risks of injuries. Please read and follow the electrical installation requirements
and instructions for your spa completely!
