the unit. These appear in italics.
The term WARNING is used to indicate situations that might endanger the
safety of operators. These appear in italics and, in some case, also in bold.
All measures indicated in this catalogue are stated in millimetres
T he CU-S range consists in:
1. a condenser unit, with air or water condensation installed external to the cell
2. an electrical control panel, located on the condenser unit
1.1 How the unit works The units CU-S are condensing parts operating by means of a sealed or semisealed a/c mains powered refrigerating compressor (single-phase or threephase), using HFC refrigerating liquids.
1.2 Safety devices and safety measures
The following mechanical safety devices are supplied by the manufacturer (fig. 2):
1. fixed side guards of the evaporator and condenser units: these are fixed to the
metal casing with locking screws.
2. Electric fan fixed external guards: these are fixed with self-locking screws.
3. Removable guards front to the condenser group: hinged doors with electrical
interlock and locking device with levers.

Below we list all the situations - from the delivery of the unit to its demolition
- in which the user will need to exercise caution in order to avoid damage to
persons.
CHAPTER 4 - Positioning the unit
Maximum caution should be used in ensuring that no one passes through
the area while the suspended load is being handled, in order to avoid any
chance of damage to persons.
CHAPTER 9 - Maintenance
Condenser and evaporator groups’ fins: any maintenance operations must
be carried out using personal protection devices (e.g. gloves) in order to
avoid any chance of damage to hands.

The CU-S ranges are air condensing units manufactured to operate automatically.
Using the machine for any purposes other than those envisaged represents an anomaly and may seriously endanger people’s safety.
3.1 Dangers deriving from using the The unit is not designed to operate in premises where explosives are stored.
unit for purposes other than Therefore, it is categorically forbidden to use it in locations where any risk of
those it is designed for explosion exists.
Should the user wish to use the unit for any purposes or in any fields other than
those intended (see ch. 8, section 8.2 of this manual), or wish to modify the unit
in any way, he should consult the manufacturer/distributor about any contraindications or dangers that may derive from the incorrect use of the unit.
The unit can be moved with lifting and transport devices. (Fig.5)
WARNING
Take the utmost care in ensuring no one passes through the platform truck’s
manoeuvring area, so as to avoid any risk to personnel while the load is
being handled.
The unit is shipped packed in a wooden case or in a wooden crate: the
movement has to be done securing the packaging with a sling in an appropriate way.
Take special care in ensuring that the packing crate containing the unit is not lif-
ted too quickly to avoid oscillations which may damage or break the unit.
