8. Storage tank temperature sensor, or thermistor, is taped to inside of Energy Station housing
at lower right and connected to Controller by two blue wires. Slide hose-clamp over
corrugated copper pipe and fasten thermistor to smooth surface of corrugated pipe, close to
manifold (
Figs.4.2.2
). Do not over-tighten as thermistor may dent and damage corrugated
pipe.
9. Using an accurate pressure
gauge, check expansion tank air
pressure. Blue cap must be
unscrewed from Schrader valve
before checking pressure
(
Fig.4.2.3
). Pressure should be
25
psi
. Adjust as necessary (with a
bicycle pump or compressor, or
by releasing air from expansion
tank).
