Tecnoclima BESST/R 42 [22/40] Hydraulic connections

HYDRAULIC CONNECTIONS

The choice and installation of the components is the installer’s

responsibility who must work according to the best practice rules and

the regulations in force. Before connecting the pipes, make sure they

do not contain stones, sand, rust, waste or anyway foreign bodies

which might damage the system.

A system “calibration” by-pass MUST be made for types 5-

6-7-8 and 13-14-15-16 (see drawing below). The by-pass

enables a better control of water flow-rate and lift, since the

provided pump is pre-equipped for a single speed.
