POSITIONING THE TEMPERATURE SENSORS
b
On initial start-up and at least every year, check that
all the pumps in the system rotate freely. Sludge and
lime scale can build up and cause seizure, especially
after long periods of disuse.
b
Protect all electrical devices under the pump before
you unscrew the inspection cap just in case water co-
mes out.
a
Never run the pump dry.
