IMPORTANT!
Remember, high voltage is still accessible in the house
breaker box even though you have turned off the spa breaker.
Keep in mind that a majority of R.C.D. tripping
problems can be attributed to incorrect wiring.
R.C.D. troubleshooting usually finds the problem.

via conduit, routed to the R.C.D. breaker box. The brown
should be connected to the R.C.D. line-in. The blue load
neutral connects to the neutral in.
RCD LINE-OUT WIRING CHECK FOR 230 V
DEDICATED SYSTEM
The brown wire should connect to load out, the blue wire
from neutral out. All wires will exit the box via conduit
routed to the spa control system.
Once you have found all wiring correctly installed, begin
to check for proper voltage. If Correct Wiring is Verified,
check to see if the proper RCD is installed.
Check the label in the system box near TB1 to determine UÊ
the maximum amperage draw for the system.
Be sure the R.C.D. is rated for more amperage than the UÊ
system will draw.
For a 230 V dedicated system, a 2-pole or 4-pole R.C.D. UÊ
with no load neutral is acceptable.
For a detailed wiring checklist, please review the previ-UÊ
ous segment of this manual on proper R.C.D. wiring or
the R.C.D. manufacturer’s instructions.
If the wiring is correct and the R.C.D. will not reset, then UÊ
unplug the pump and try to reset the R.C.D.
If the R.C.D. trips again, then unplug the blower and UÊ
push the reset button. If the R.C.D. continues to trip,
then do the same procedure for the ozone generator.
If the R.C.D. stops tripping after you unplugged one UÊ
of the spa’s components, turn off the power to the
spa then plug in each component except the one that
tripped the R.C.D.
Power up the system. If the R.C.D. no longer trips, then UÊ
you have correctly identified the problem.
Repair or replace the component as instructed by the UÊ
spa manufacturer.
If you have unplugged all of the spa’s components and UÊ
the R.C.D. still doesn’t reset, then the problem is most
likely a ground fault in the heater.
Disconnect the heater, and test.UÊ
