VE150 Cooling Unit
15
INSTALLATION AND USE
The Isotherm VE150 cooling unit is specically designed to be installed inside a box that has been
specially made for chilling and storing food, or can be used to chill a compartment that already exists
but is not in use.
The unit is equipped with all the components necessary for its assembly, which is easy and does not
require specic tools.
During the producon stage, it is loaded with the appropriate refrigerant and delivered ready for use.
To simplify installaon, the system is divided into 2 secons: the condenser unit and the evaporator
unit.
These secons are connected together via a hose equipped with quick couplings that can be easily
connected and disconnected repeatedly without any loss of refrigerant.
When one of the two parts (condenser unit or evaporator unit) must be replaced or modied, the gas
emptying/recharging procedure must be repeated.
The box housing the evaporator must be well insulated. Use a polyurethane foam or insulaon panels
with the following recommended cross-secons:
Box Volume (l) Thickness of Insulaon Material
L ≤ 100 30 mm
100 < L ≤ 150 50 mm
150 < L ≤ 200 80 mm
200 < L ≤ 250 100 mm
The baery capacity must be at least 75 Ah to enable correct unit operaon.
All electrical power supply devices must always be kept in good condion.
N.B. The cooling capacity of the unit is determined by the resistor connected between the terminal “T”
on the control unit and one pole of the thermostat. For volumes greater than 150 litres or for boxes/
compartments made using material with low thermal insulaon, the resistor must be present. For
volumes less than 150 litres, the resistor should be omied. See the wiring diagram.
INSTALLING THE CONDENSER UNIT
The condenser unit must be installed horizontally, and can operate constantly at a maximum gradient
of 30°. It must be installed in a well-venlated environment, protected from splashes of water. If the
unit is installed in a conned space, venlaon should be improved by creang venlaon holes with
a diameter of 8 cm, one located on the top and
one on the boom of the installaon area. The unit
must be secured through the four holes situated on
the condenser unit support base.
See the gure on the right.
Place the condenser unit near the locaon where
you plan to install the evaporator unit, so as not to
exceed the length of the connecng hose (about
2 m).
