Thank you for purchasing a Climma CWS system!
This manual will provide necessary information for the proper installation, operation, and maintenance of
your Climma system.
Climma chiller and products are designed and produced to the highest standards and they are all tested
in the factory. If your Climma system is used according to the guidelines in this manual, it will guarantee
you trouble free operation for many years.
If you require assistance, please contact one of our many authorized service centers. To find the service

WARNING
This unit should only be used for the purposes for which it was designed. The manufacturer declines all
responsibility for any damage caused by incorrect or unreasonable use, such as:

improper use by untrained persons;

technical modifications or operations not suited to specific models;

use of non-original or non-specific spare parts;

1.2. System features

Following the main features of the Climma DC chillers:

Variable Output from a Single Air-conditioning Unit. Depending on the heat load requirements,
the compressor frequency varies controlling the output capacity, to produce faster cooling and
heating, significantly improving the comfort on-board.

Water Cooled Inverter Compressor. Climma's water cooled inverter protects the DC brushless
compressor from excessive temperature, current overload and irregular voltage supply, allowing
it to be installed in the engine room without additional ventilation. Added to this, the electronic
control provides continuous monitoring of the compressor curve to keep the unit within safe
operating limits, eliminating also stop-start cycles.

Eco mode. This function has been specifically developed to optimize the power consumption of
the system in three principle ways: it enables the chiller to work more efficiently with a smaller
output generator than would ideally be required; in ECO mode the power consumption is further
reduced during night operation when only a courtesy/night generator is working running and
less power is needed; ECO mode allows the air-conditioning to run while on the dock with a
limited shore power supply.

No Start Load. By using a DC compressor with inverter the Climma compressor starts at a low
frequency requiring a fraction of the power.

Up to 50% energy saving
A Climma centralized air-conditioning system includes different products: the Climma DC chiller, fancoils
installed in each cabins, fresh water piping that connects the chiller to the fancoils, sea water piping
bringing sea water to the chiller condenser, the fresh and the sea water pumps.
While the Climma system is running in cool mode, the Climma DC chiller is cooling the fresh water that
circulates in the fresh water circuit to the fancoils; heat is removed from the cabins through fancoils,
blowing fresh air into the cabins.
While in heat mode (reverse cycle mode), the Climma DC chiller is heating the fancoil water circuit that
brings heated water to the fancoils, allowing them to blow heated air in the cabins.
