240 VOLT INSTALLATION 
Use only a qualified Licensed Electrician to make 240 
Volt electrical installations. 
Your 240 Volt Bullfrog Portable Spa requires a 
dedicated 50 AMP electrical circuit and a minimum 
supply wire size of 6 gauge. It is important that this 
circuit is dedicated (not being used by any other 
electrical appliance) or your spa may not function 
properly. 
Position your Bullfrog Portable Spa at least 5 feet 
(1.5m) from all electrical outlets or devices. 
30 AMP Conversion Option:  If you do not have 50 
AMPS of electrical service available, your authorized 
Bullfrog Portable Spa Dealer or electrician can easily 
convert your spa to operate on 30 AMPS with a 
minimum supply wire size of 10 gauge. Please be 
aware, that spas converted to 30 AMPS are only 
capable of heating the water when the circulation 
pump is in low-speed, not high-speed. This heating 
limitation is acceptable in most climates as well as in 
indoor installations. 
ELECTRICIAN'S INSTRUCTIONS: 
NOTICE:  As of January 1, 1994, the National Electric 
Code (Article 680-42) requires that all spas, hot tubs, 
and associated electrical components shall be 
protected by Ground Fault Circuit Interrupters. 
Providing 120 Volt Service to the Bullfrog Portable 
Spa: As per code, supply a GFCI protected, 3-wire 
(Line 1, Neutral & Ground), 20-AMP, 60HZ, Single-
Phase service to the front, left corner (when you are 
facing the control pad) of the Bullfrog Portable Spa. 
This service must include a disconnect that is visible 
from the spa and located not less than five feet from 
the spa and not more than 50 feet from the spa (a 
GFCI Sub-Panel may be used to substitute the 
disconnect if located within the same parameters). 
Providing 240 Volt Service to the Bullfrog Portable 
Spa: As per code, supply a GFCI protected, 4-wire 
(Line 1, Line 2, Neutral & Ground), 50-AMP, 60HZ, 
Single-Phase service to the front, left corner (when you 
are facing the control pad) of the Bullfrog Portable 
Spa. This service must include a disconnect that is 
visible from the spa and located not less than five feet 
from the spa and not more than 50 feet from the spa 
(a GFCI Sub-Panel may be used to substitute the 
disconnect if located within the same parameters). 
Installation of the GFCI: All conductors except the 
green ground must be routed through the GFCI, 
including the neutral. Never bypass the neutral line. If 
the neutral line is bypassed, then the current will be 
imbalanced and cause the GFCI to trip. 
Note: For a GFCI wiring diagram, please contact 
Bullfrog International, L.C. or an authorized Bullfrog 
Portable Spa Dealer.
