2.2 Hydraulic connections
Pipes
Adhere to the installation standards and trace the pipe routing
carefully:
 observe the drain direction (inlet/outlet) indicated on the unit
 the following accessories are essential to any hydraulic system
and must also be installed
- 3 bar valve-gauge assembly (mandatory)*
- automatic air bleed valves at high points
- discharge nozzles at low points
- balancing valves
- additional expansion vessels if necessary
- thermometer pockets, etc.
* the safety valve, which is mandatory on the hydraulic circuit,
must be tested manually at least once a year.
 the pipes and tubes should not transmit any forces or
vibrations to the exchangers. Hoses must be used to connect
water pipes.
 use at least 2 shut-off valves on each circuit in order to isolate
the unit
- screw in the system's flexible connectors/pipes
by hand
- tighten them using two spanners
Failure to tighten with two
spanners could cause the
couplings to rupture and
may result in the equipment
warranty being voided.
Fasten the water pipes to the walls with brackets lined with highly flexible rubber to prevent the transmission of vibrations.

Diameters calculated for a 15m hydraulic connection between the
heat pump and the system outlet.
A screen filter must be added
to the heat pump's primary and
secondary circuits. Failure to
follow this instruction may result
in blocked or fouled exchangers.
CIAT accepts no responsibility for
clogging or malfunctioning of the heat
pump in the event of failure to install
screen filters.
