A4 Testing Flow Switch
When the “FL1 or FL2” message appears, it means the ow switch contacts
have failed to close when the pump was turned on, or failed to open when the pump
was turned off. This could be caused by an excessively dirty lter, an obstruction in
the ow path or by a bad switch. The rst thing to look for is an excessively dirty lter
or an obvious obstruction, remembering (while not likely) that it is possible for a small object to work
its way into the plumbing where it will not be obvious. After verifying no obvious blockage exists, the
ow switch can be tested. Refer to page 16 for switch testing instructions.
A5 About Fuses
When current passes through a conductor the conductor heats up. If the conductor is a heavy piece
of wire or a strip of metal, it will pass large currents and generate very little heat. If a wire is ne, or
a strip of metal is thin, it will heat up at lower current levels. Fuses rely on this principle to protect
circuits from massive current ows by simply melting if their current rating is exceeded. By selecting
different alloys for the fuse element, fuses can be made to have their current rating exceeded for a
short period of time. Such slow-blow fuses are excellent for protecting motor circuits where start-up
currents (surge currents) are higher than running currents.

Testing Fuses
A good fuse should read continuity (0 Ω); a blown fuse will read no continuity (innite ohms). See Figures 6
and 7 for testing methods.
CAUTION: Make sure replacement fuses are exactly those listed above. Never test a fuse for continuity
while installed in the fuse holder.
