If the supplied
10 ft GFCI power cord
(US only) cannot reach a
dedicated, grounded wall
outlet, it is necessary to
install a 3-wire,
hard-wired connection.
These diagrams illustrate
that conguration.
For enhanced heater
performance the use of a
4-wire power connection is
necessary.
A pressure sensitive
terminal block (bonding
lug) is attached to the
outside surface of the
load box. This permits the
connection of a bonding
wire between this point
and any metal equipment
chassis, metal water
pipe, or metal conduit
within 5 ft (1.5m) of the
spa. The bonding wire
must be at least a #8
AWG (8.4 mm
²) solid
copper wire.
