4. Hydraulic connections

All hydraulic connections must be made based on the best practices : drain valves, isolation valves, purge point
installed in the upper part of the network, filtration, sludge pots, lagging pipes in order to avoid any risk of
condensation in operation with cold water, etc.
Before filling, the installer must ensure that the water quality complies with the VDI directive 2035. Before starting up
the system, it is necessary to correctly place the filters, to perform a complete flushing of the hydraulic network and
to treat the water in order to avoid clogging the circuit.
CAUTION: Do not apply a torque greater than 30NM on the hydraulic connections of the cPIA control panel. Be sure to
use a torque wrench when tightening the hydraulic parts. In case of leakage or replacement of the hydraulic
components, it is necessary to replace the seal.
