Identification of components

The main components of the hydraulic station are:
– Two isolating valves (Fig. 11, Item 1 & 2) with integral
thermometers which display the solar primary flow
3
and return temperatures.
– A safety group (Fig. 11, Item 3, supplied unconnected),
which protects the solar primary circuit.The pressure
4
relief valve and pressure gauge are integrated in the
safety group.
– A non-return valve in both feed and return prevents
the possibility of gravity circulation in the solar
primary circuit.
– A solar circulation pump (Fig. 11, Item 4).
– A flow meter with fill & drain valve and shut-off valve
(Fig. 11, Item 5).
– An air separator.
The heat transfer fluid is circulated by the solar circulation
pump integrated in the hydraulic pump station (Fig. 11).
The hydraulic station has a solar differential temperature
controller (Fig. 11 Item 6) integrated into the front
insulation moulding.This is pre-wired to the solar pump.
