INSTALLATION
HYDRAULIC CIRCUIT AND ITS COMPONENTS
Differential pressure switch
We will use it along with the flow switch and both devices will be redundant. Their function is similar: they protect the plate
exchanger from breakage. Air pockets may be generated after filling the circuit with water. We will have to make sure that
there is no air to guarantee that this component works properly: we will proceed to purging by loosening the nuts of the
tubes (please see below, 1.).
Any damage to the plate exchange caused by accumulated air in the pressure switch that prevented it from working
correctly
will not be covered by the warranty
.
Regulating devices
Condenser water regulating valve
The regulating valve controls the condensation pressure mechanically by preventing that it decreases when the water
temperature is too cold. For that it closes the water flow proportionally.
The regulating valves shall be adjusted if that was not made from factory. For that use the valve stem or the control stick
depending on the model.
The inlet water temperature shall be below 26°C to adjust the regulating valve. We will adjust it so that the condensation
pressure is at 23 bars.
1. Loosen until water comes out and
tighten the nuts again.
