Absolute care must be taken to ensure adequate air volumes on the condenser coil intake and delivery sides. It
is most important to avoid recirculation between the intake and delivery: failure to observe this prescription will
result in poor performance or interruption of normal operation . It is therefore necessary to observe the following
clearances:
- around the perimeter : a minimum distance of 1.5 or 1.8 metres according to the model. (see dimension sheets).
- top: make sure air expulsion is not impeded in any way.
High walls (> 5 metres) near the machine may interfere with correct functioning. When units are side by side the
minimum distance between them should be 3 metres (see figure).
3 m

Water pipelines must be installed in accordance with local and national rules and regulations (see charts enclosed
in this manual)
- Piping should be connected to the unit using flexible joints so as to avoid vibration and compensate for any
thermal expansion (adopt the same procedure for pumps)
- The following components should be installed on the pipelines:
- shut-off valves, temperature gauges and pressure gauges for regular maintenance and servicing.
- temperature probe sockets (if temperature gauges are not fitted).
- gate valves to separate the unit from the hydraulic circuit
- strainers (inlet pipes) with mesh no larger than 1 mm (obligatory in the case of plate type evaporators) to protect
heat exchangers from debris and foreign matter in pipelines.
- bleed valves installed on the upper parts of the circuit for venting of air.
- expansion tank with water filling group to maintain circuit pressure and to compensate for water thermal
expansion.
- drain cock and, where necessary, drainage tank for emptying the system during maintenance and seasonal
shutdowns.
- connection manifold between water in and out of evaporators (units with 2 independent evaporators, models:
32.2, 37.2, 50.2, 55.2), if not already ordered as option. Insert a pipe downstream the manifold to insert a
sensor to control the water leaving the chiller (option).
