Description
The unit you bought is an Heat Pump a machine aimed to cool
/ heat water (or water-glycol mixture) within the limits described
in the following. The unit operation is based on vapour
compression, condensation and evaporation according to
reverse Carnot cycle.The main components are:
- Scroll compressor to rise the refrigerant vapour pressure
from evaporating pressure to condensing pressure.
- Evaporator, where the low pressure liquid refrigerant
evaporates to cool the water. In "Cooling Mode" and
where the refrigerant condensate to heat the water in
"Heating Mode".
- Coil, where high pressure vapour condensate rejecting
heat removed from the chilled water in the atmosphere
thanks to an air cooled heat exchanger. In cooling mode
in heating mode the low pressure refrigerant evaporate
taking heat from low temperature ambient.
- Expansion valve allowing to reduced the pressure of
condensed liquid from condensation pressure to
evaporation pressure.

Operating limits
Storing
Environmental conditions must be within the following limits:
Minimum ambient temperature
Maximum ambient temperature
Maximum R.H.
Storing below the minimum temperature may cause damage to
components. Storing above the maximum temperature causes
opening of safety valves. Storing in condensing atmosphere
may damage electronic components.
Operation
Operation out of the mentioned limits may damage the unit.
In case of doubts contact manufacturer representative.
