Testing a System with Power (cont.)
THESE READINGS SHOULD BE TAKEN UNDER
PEAK LOAD CONDITIONS.
IMPORTANT
If the voltage is not in the acceptable range, call
an electrician or the local electric company to diagnose
the problem.
TO DETERMINE THE CAUSE OF A BLOWN POWER INPUT
FUSE
Perform the following
sequence of tests
.
Test the System
Turn the power off.
UÊ
Be sure to replace the system power input fuse with the
UÊ
same type.
Unplug the blower and all pumps.
UÊ
Restore the power and verify system operation.
UÊ
If the fuse blows, power down the system and then re-check
UÊ
the internal system wires and connector for burns, cracks or
cuts in insulation.
Or, if the fuse does not blow, turn the power off and plug in
UÊ
the pump.
NOTE:
Be sure to test each device individually.
Test the Pump
Restore the power and activate the pump.
UÊ
If the fuse blows, there is a
UÊ
pump problem.
If the fuse does not blow, turn off the power.
UÊ
Test the Blower
Plug in the blower.
UÊ
Power up the system and activate the blower.
UÊ
If the fuse blows, then there is a
UÊ
blower problem.
If the fuse does not blow, the combined pump and blower
UÊ
amperage may be excessive. To verify this, first check
with your spa manufacturer for amperage draw limits on
each device.
Since the blower should now be running, you can check
UÊ
the amperage draw with an ammeter by measuring around
the black blower wire and compare with manufacturer’s
specifications.
TEST THE AMPERAGE DRAW
Turn off the power, disconnect the blower, make sure the
UÊ
pump is plugged in, and restore power.
Start the pump and switch to
UÊ
high speed (if available), this
should draw the most current.
Make sure all jets and valves
UÊ
are open.
Check the
UÊ
amperage at the
red pump wire. Compare your
reading with manufacturer
specifications. (If the other
plug-in devices exist, they
should be tested in the
same way.)
If the amperage draw for
UÊ
each device is within manufacturer’s specifications, the
problem could be a nuisance spike in the pump, or water in
the blower.
NOTE:
These slow-blow fuses are not always discolored when
blown. Always test continuity of a fuse with an ohmmeter.
NOTE:
Miswiring of the spa is the most common reason for this
fuse to blow. However, a lightning strike in the area is a possible,
though less likely, cause of the failure.
ELECTRICAL PROTECTION
1. Local
Disconnect:
A local disconnect (sometimes referred to as an “electrical
disconnect”) is installed apart from the main service panel.
The local disconnect must be installed where readily acces-
sible and within sight of the spa, but at least 5’ (1.5 meters)
from the inside wall of the spa.
2. GFCI:
It is required by code to install a Ground Fault Circuit Inter-
rupter (GFCI) in the supply power for a spa.
NOTE:
A GFCI power cord is included with a 120VAC spa. This
can be used for a cord-connected 120V setup only, and only in
place of a stand-alone GFCI.
