• Before connecting the pipes, make sure that they do not contain rocks, sand, rust, dregs
or, in any case, foreign bodies which may damage the system.
• It is appropriate to carry out a by-pass in the system in order to be able to perform
washing of the plate exchanger without disconnecting the appliance. The connection
pipes must be supported so that they do not weigh on the appliance with their weight.
