Hydraulic connections
The minimum equipment required for the external hydraulic circuit are:
•
Pipes with diameter equal to the diameter of the circuit connections, indicated in the hydraulic diagrams in
paragraph 4.6.
•
Two shut-off valves to isolate the chiller from the system in correspondence of the inlet and outlet hydraulic
connections.
•
System draining valves in its lowest points.
•
Flexible couplings to join the chiller external hydraulic circuit.
•
A filter on the chiller inlet return pipe, with metal mesh of 50 ÷ 80 μm.
•
Suitable insulation on the pipes to prevent condensation and reduce thermal on the circuit.
Before connecting the chiller to the utility, make sire that the pipes used do not contain dirt or
processing residues; if in doubt, perform one or more washing cycles.
The position of the hydraulic connections is shown in the dimensional drawings in paragraph 5.3.
Remove the protective plugs from the connections and connect the pipes of the external hydraulic circuit complying
with the inlet and outlet direction of the chiller. The inlet and outlet of the hydraulic circuit are marked with the labels
shown on page 16.
