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
