8.3 CHILLED WATER CIRCUITS CONNECTION - FREE COOLING DESIGN
Machines in Free Cooling execution are supplied with water circuits connected to the pre-set valve and water condenser.
Accordingly it will be necessary to set up the circuit water supply and discharge lines. The diameters of the pipes and the inlet and
outlet ttings are identied in the order conrmation or in the following tables for standard models (identied by the code number
sequence).

The maximum pressure of the water supply to the coils is 16 bar (1.6 MPa). The maximum pressure dierence between
the water inlet pipe to the valve and the outlet pipe is 1.8 bar (180 kPa), as at pressure dierences greater than this value the return
spring would not be able to shut o the water ow. In the event of greater pressure dierences, it will be necessary to install pressure
reducing valves upstream of the valve.
8.3.1 SETTING UP THE CHILLED WATER CIRCUITS - FREE COOLING DESIGN
The positions of the water inlet and outlet connections are indicated in the gure below. The connections can also be iden-
tied by the adhesive labels applied on the pipes of the unit near the connections.

To ensure that circuit pipes are installed correctly, we recommend you follow the instructions below:
• Use piping suited to the circuit pressure (copper, steel or plastic).
• Secure pipes with suitable brackets.
• Insulate both pipes with Armaex type insulation.
• Install shut-o valves to facilitate maintenance.
• Install a Thermometer and Pressure gauge on the inlet and outlet.
• Install a discharge outlet at the lowest part of the circuit.
• Install a 50 μ mechanical lter on the supply line.
• Install a balance valve on the return line.
• Use water and glycol where necessary.
