1.0 PREFACE
1.0.1 Electrical Requirements
All Spa electrical wiring should be performed by a licensed electrician and must comply
with all NEC (National Electrical Code) and state and local code requirements.
The electrical loads for connections to this system MUST NOT exceed the rating
specified in this manual. Failure to comply with these specifications and/or improper
wiring may cause hazardous operating conditions and/or damage to the controller.
1.0.1.1 Ground fault Circuit Interrupter (GFCI)
Since January 994, a Ground Fault Circuit Interrupter is required by all electrical Spa
installations. The National Electrical Code (NEC) also states that a service disconnects
should be located near the Spa but no closer than 5 feet. A GFCI could be used for this
purpose.
All 20 Vac Spa require a dedicated 20 Amps GFCI service connection, all 240 Spa
require a dedicated 50 Amps GFCI service connection with a 6/3 AWG (four wire) all
copper conductors. In order to conserve electricity we recommend using 240 Vac
connections in all 240 Vac capable Spa.
It should also be verified that a dedicated service is used with no other circuits
connected to it.
1.0.1.1.1 GFCI In- line wiring
• Black and Red wires feeding the GFCI are connected to a properly sized circuit
breaker.
• White wire should be connected to the neutral bar and the Green is connected
to the ground bar.
1.0.1.1.2 GFCI 240Vac 3 wire circuit
A 240 Vac 3 wire service could be used if it does not operate any 20 Vac devices.
• Black and Red wires feeding the GFCI are connected to a properly sized circuit
breaker.
• White wire is not required and the Green is connected to the ground bar.

Regency Owner’s Manual Page 5
1.0.1.1.3 GFCI 120/240 Vac 4 wire circuit
A 240 Vac 4 wire service could be used if it does operate any 20 Vac devices.
• Black and Red wires feeding the GFCI are connected to a properly sized circuit
breaker.
• White wire should be connected to the neutral bar and the Green is connected
to the ground bar.
The White load wire must be connected to the neutral out terminal. Proper
installation of the neutral wire is essential for proper operation. If not wired
properly, the GFCI will trip when any of the 20 Vac devices is turned ON.
1.0.1.1.4 GFCI Concerns
If the GFCI does not stay engaged as soon as power is applied to the system, it could
indicate that it is not wired correctly. Please verify that all the connections are correct,
generally if the GFCI does not stay engaged, it is a wiring problem with the neutral wire.
The Neutral and the Ground wires cannot touch anywhere otherwise the GFCI will trip.
1.0.2 Risk of Electrical Shock
As a Spa owner some of the risks of electrical shock are but not limited to the following:
• All supply circuits must be disconnected before accessing the Relay Board
Terminals. The cover should only be removed by a qualified technician.
• Do not operate the Spa with the controller cover removed.
• Use copper wire only while installing the system.
• Do not allow any electrical appliance: lights, telephone, radios, televisions etc
within 5 feet of the Spa.
• Never try to operate any electrical device from inside the Spa.
1.0.3 Owner’s Res onsibilities
As a Spa owner some of your responsibility are but not limited to the following:
• Protect your Spa from freezing or any other damage.
• Do not permit children to use or access to the spa unless they are supervised at
all times.

Regency Owner’s Manual Page 6
• Before entering the Spa make sure that the water temperature never exceeds
04°C (40°C). Water temperature between 00°F (38°C) and 04°F (40°C) are
considered safe for adults use.
• Pregnant or possible pregnant women should limit Spa’s water temperature to
00°F (38°C) since excessive water temperature has a high potential for causing
fetal damage.
• The use of alcohol, drugs or medications before or while using the Spa made lead
to unconsciousness that could lead to drowning.
• Persons with infections or sores should never use the Spa. Temperature of the
spa may allow the growth of infectious bacteria if the system is not properly
sanitized.
• Persons using medication, suffering from obesity, history of heart disease, low or
high blood pressure, diabetes or problems with the circulatory system should
consult a physician before using the Spa.
• Adults should never use the Spa alone, always enter and exit the Spa slowly.
