(A1 Technical Data).
I.1.1 MACHINE IDENTIFICATION
The units feature a serial number plate located on the side which
includes machine identification data.
I.2 DECLARED CONDITIONS OF USE
EH units are packaged cooling cycle reversible heat pumps with air
evaporation/condensation and axial fans complete with a hydraulic
pump.
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.
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.

Standard functioning
Operation FI15
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 ∆T = 4 ÷ 8°C.
○ Minimun water pressure 0,5 Barg.
○ Maximum water pressure 6 Barg.
N.B.:
For evaporator outlet water at a temperature below 5°C, please contact
the EMMETI 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.
