Hidraulic circuit for WPH and WPV units and their components:
-
Inside hidraulic circuit and its components, sheet heat exchanger is the most delicate part
affected, and as a result should follow these guidelines at least
-
The water filter must be installed and should contain inside it a mesh to retain particles of diameter
less than 0,5- Ø >0,5mm
-
Both filter and flow switch maintenance must be made within a few periods in which they can
avoid lock dressings
-
Should be respect the indication of water inlet or outlet of unit and install if it derives from a by-
pass valve
-
In case of working with open circuits, which the water quality is not correct and is noted down in
the table, is recommended install a secondary exchanger to avoid its deterioration.
