APPLIANCE DESCRIPTION

The refrigerating units are comprised of an R134A evaporating unit, a condensing
unit and a R134A compressor designed to create capillary refrigerating systems with
evaporation temperatures between -25°C and +10°C. The compressor can be powered
at both 230 V AC and 24 V DC as well as 42 V DC. Only the direct current versions (V
DC) have a compressor control unit that is automatically adjusted according to power
voltage. The compressor is able to operate silently as well as being efficient and safe
up to a permanent inclination of 30°. The control electronics (on DC models only), to
prevent early compressor breakdowns, caused by over-frequent thermostat cycles,
is programmed to create a 3-minute delay between each stop and the subsequent
restarting of the compressor itself.

Introduction

The two main parts of the refrigerating unit (condenser and evaporating units) have
been pre-loaded with R134A gas, in precise amounts, optimised to achieve the best
possible cooling performance. The first connection between them already means an
instant passing of gas between the two components, thereby unbalancing the amounts
of gas.
Always keep the connection between the same units. Do not connect two units
already used previously with other units. This will cause insufficient cooling
performance or even the breakdown of the refrigeration equipment.
For more information on the possible unit combinations, see the table.
