120/240 Volt Conversion
. All spas are shipped configured for 240
volt (3 or 4 wire systems). Please check the nameplate on the control
enclosure to identify the type of system in your spa. If the nameplate
indicates a 120/240 Volt type system, then it is possible to convert the
spa to 120 volt operation.
30/50 Amp Conversion. Some homes may have limited power service.
It is possible to operate a 240 volt spa system using a 30 amp breaker.
Connect 240 volt power to the system as previously described, then set
it to operate in the low power mode. To set the controller to operate in
low power mode, you must set system option P3 to 1. Please read the
note on page 18 and the warning on page 19.
Note
: Only experienced service personnel should perform
conversions. Improper modifications may cause damage to the
control system and / or the attached heater and pump motors.
