INSTALLATION
INSTRUCTIONS (CONTINUED)
ELECTRICAL REQUIREMENTS
It is the responsibility of the spa owner to ensure that all electrical connections are made in accor- dance with all electric codes in effect at the time of installation.
240 Volt:
All connections must be made in accordance with the wiring diagram found on the inside of the control box cover. Connections should be made with copper conductors only – aluminum wiring should not be used with this system. All conductors, circuit breakers, and/or fuses must be sized in accordance to the Total Amperage Load as specified:
•Permanently connected
•Rated 240V, 60Hz, 50A, three wires plus ground (6 AWG copper)
•Fuse or circuit breaker size: 50 amp
This equipment is designed to operate on 60Hz Alternating Current only at a voltage of 240. Units to be operated at 240V must have all connections made by a qualified electrician in accordance with any electric codes in effect at the time of installation. All 240V units require a three wire plus ground (line 1, line 2, neutral, ground). Refer to the label at the terminal block.
A pressure wire connector is located on the exterior of the control box. If the installation includes a common bonding grid (reinforced concrete slab, ground plate beneath the spa, or any metal water pipe connection), this pressure wire connector should be bonded, with at least #8 AWG (8.42mm2, #6 in Canada) copper wire, to any metal ladder, water pipe, or other metal, within five feet of the spa.
120 Volt:
120V units must only be connected to a properly grounded, grounding type15 amp receptacle. 120V equipment is designed to operate on 60Hz Alternating current only at a voltage of 120, 12.5 amp. maximum load.
To Convert 120V to 240V
All connections must be made by a licensed electrician.
1.Disconnect from power and remove cord.
2.Move red wire
3.Move the Heater Mode selector (J23) on the Control Board from (20A) to (50A) position. Ground Fault Circuit Interrupters (GFCI), #8145, are available from your Dealer.
