120/240 VOLT SYSTEMS

Attn: All electrical connections must be made by a licensed
electrician. Failure to do so will void the spa warranty.
Optional 120/240 Volt Models
Franklin / Revere / Madison
Special Note:
Franklin, Revere, and Madison Models are pre-wired for 240 Volt installations from
the factory.
Electrical Requirements for 120 Volt
The spa must be connected to a "dedicated" 120 Volt, 15 amp grounded circuit.The term
"dedicated" means the electrical circuit is not being used for any other electrical items
(patio lights, appliances, garage circuits, etc.). If the spa is connected to a non-dedicated
circuit, overloading will result in "nuisance tripping" which requires resetting of the break-
er switch at the house electrical breaker panel.The dedicated circuit must be properly
wired; that is, it must have a 15 amp circuit breaker in the housebreaker panel, number 12
AWG or larger wire (including the ground wire) and the correct polarity throughout the
circuit. NEVER CONNECT THE SPA TO AN EXTENSION CORD!
Installation Instructions Using An Optional GFCI Power Cord
For 120 Volt models with 15 feet of usable power cord (this is the maximum length allowed
by Underwriters Laboratory and the National Electric Code.) When your electrician is
installing the electrical outlet, please make sure it is located no further away than 10 feet
from the equipment compartment door. For your safety, the National Electrical Code
requires that the 15 amp single receptacle electrical outlet be located no closer than five
(5) feet from the spa.
The Ground Fault Circuit Interrupter (G.F.C.I.) is located at the end of the power cord.
This device is for your protection. It is very important to protect it from rain and other
moisture. Once a month, with the plug connected to the power supply, push the test but-
ton located on the G.F.C.I.The reset button should pop out, shutting off power to the spa.
Next, push the reset button back in.The button should stay in restoring power to the spa.
If the Interrupter fails to operate in this manner, there may be a problem. Disconnect the
plug from the receptacle until the source of the malfunction has been identified and cor-
rected by an authorized service agent.
WARNING: Removal of the G.F.C.I. from the spa power cord at any time will
result in an unsafe spa and void the warranty.
Special Note:
Heater needs to be converted from 240V to 120V when wiring spa 120V.
• See wiring diagram on equipment pack for 120 Volt conversion.
