I.2.1 MACHINE IDENTIFICATION
The units feature a serial number plate located on the side which
includes machine identification data.
I.3 DECLARED CONDITIONS OF USE
EWMIG units are packaged cooling cycle reversible heat pumps with air
evaporation/condensation and axial fans.
The units are air cooled packaged water chillers with axial fans.
They are suitable in air conditioning installations and industrial
processes where chilled and hot water is required, not for human
consumption.
The units are designed for outdoor installation.
The units comply with the following Directives:
○ 2006/42/EC Machinery Directive
○ Low voltage Directive 2006/95/EC
○ Electromagnetic compatibility Directive 2004/108/EC
○ Pressure equipment directive 97/23/EEC (PED)
DANGER!
The machine has been designed and manufactured
solely and exclusively to function as an air
evaporation heat pump; any other use is strictly
PROHIBITED. Installing the machine in an explosive
environment is prohibited.
DANGER!
The machine is designed for outdoor installation.
Segregate the unit if installed in areas accessible to
persons under 14 years of age.
IMPORTANT!
The unit will function correctly only if the
instructions for use are scrupulously followed, if
the specified clearances are complied with during
installation, as well as the use restrictions indicated
in this manual.

In summer mode:
Maximum water inlet temperature 25°C.
In winter mode:
Maximum water inlet temperature 55°C
Permitted temperature differentials through the heat exchangers
○ Temperature differential OT = 4 ÷ 8°C.
○ Minimun water pressure 0,5 Barg.
○ Maximum water pressure 3 Barg.
N.B.:
For evaporator outlet water at a temperature below 5°C, please contact
the HITECSA pre-sales service before ordering.
In the permitted field of operation, the compressor and inverter are
protected by a controller by means of continuous monitoring of the
current absorbed by the compressor, operating pressure and output
temperature. The compressor can modulate the rotation speed
automatically, regardless of the set-point request if it goes out of its
proper field of operation.
