A dry room that can be ventilated is the suitable location for the appliance's installation. There should be
a good air ow around the compressor/condensing unit. Therefore the area around the unit should not be
obstructed by boxes or other objects. Place the equipment away from sources of heat (radiators, heaters
of any kind, etc.) and far from the inuence of continuous air movement (caused by fans, air conditioning
units, etc.). If it is unavoidable to install near a heat source, use a suitable insulating plate. Also avoid
exposure to direct solar irradiation; all of this causes the temperature inside the refrigerated compartment
to rise with negative consequences on operation and energy consumption. The apparatus must not be used
outside nor be exposed to rain.

MIN
8.3 ELECTRICAL CONNECTION
ATTENTION
Check that the network voltage matches the one displayed on the identication plate of the appliance,
and that the power is adequate. Check on the socket that the power supply voltage provides rated voltage
(±10%) when you start up the compressor. The plug should be directly connected to the electrical socket. It
is forbidden to connect the plug to the socket by means of multiple socket extensions or adaptors. The plant
power supply socket must be tted with a disconnection device from the mains electricity (dimensioned to
the load and in compliance with Standards in force), which guarantees complete disconnection in category
III (3) over-voltage conditions and therefore protects the circuits against earth faults, overloads and short
circuits. Do not route the electricity cable in passageways.

into an appropriate cold storage container.
THE INTERNAL TEMPERATURE IS NOT LOW ENOUGH
CAUSE SOLUTION PERSONNEL
AUTHORISED
Evaporator/s obstructed completely
by ice
Carry out an additional defrosting cycle. USER
Wrong temperature setting Set the appropriate temperature.
The appliance is aected by draughts or is
exposed to direct or reected sunlight
Remove any draughts and prevent any direct
or reected sunlight.
Insucient air ow for
cooling to the condenser
Remove anything which could obstruct
the circulation of air through the condenser
|(sheets of paper, cardboard, insucient slots in grille, etc.).
Internal fans at standstill or with fans damage TECHNICAL
ASSISTANCE
Internal ventilation is too high
Thermostat / Electronic control board
not ecient
Replace the thermostat/electronic control board.
If the control unit is set up especially for the R290 refriger-
ant, it must only be replaced with an original replacement
from ISA. Replace the temperature probes only after check-
ing which of the two is not operating eciently.
Condenser unit blocked by dust
or dirt in general
Clean the condensing unit thoroughly.
The condenser in particular operating environments
(e.g. presence of dust, presence of excessive humidity, etc.)
when the performance of the equipment deteriorates requires
careful cleaning.
Insucient refrigerant
load in the cooling system
Find the cause behind the lower amounts of coolant and
eliminate it. Top up the coolant. If necessary, empty the
system before topping up.
THE COMPRESSOR DOES NOT START-UP OR OPERATES FOR A FEW MOMENTS
CAUSE SOLUTION PERSONNEL
AUTHORISED
No electric power supply
to the appliance
Check if there is a power cut.
Close the various switches on the power supply line.
USER
Excessively low power voltage Check that the network voltage of the power supply cable is
of a rated value of 220V +/- 10%.
Temperature set too high If the temperature is higher than the air temperature
in the display chamber, the compressor will not start.
Set the suited temperature if the current temperature
is not low enough.
Intervention of the maximum pressure
switch (where present)
Check the reasons why the pressure switch is operating at
maximum pressure levels, such as: air condenser obstructed,
condenser fan with air stopped, ambient
temperature too high, pressure switch defective.
