INSTRUCTIONS
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 (8.42mm
2 , #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 (TB-1) to (TB-4) as indicated by
gray area.
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.
