This means that on a double pump should I save the connection point L c and a heat exchanger to maintain the connection point P with the point X unchanged
This means that at the double pump, I have to keep the L point connection with the heat exchanger and keep the P point connection to the X point unchanged.
This means that in double pump, I must keep the connection between L point and heat exchanger, and keep the connection between P point and X point unchanged.<br>
