Principle of Operation:   

 
An  intermediate  heat  exchanger  (DP)  should  be  installed  to  prevent  ground  water  damaging  or 
contaminating the unit’s internal heat exchanger. A plate heat exchanger that is able to be cleaned 
is recommended for this situation that can be disassembled for cleaning and repair or any damage 
plates  can  be  replaced.  Anti-freezing  measurement  must  be  adopted  to  protect  the  ground  water 
circuit.
