6. RECOMMENDATIONS
This unit is not designed to carry special loads which emit
corrosive gas.
These kind of products can impact unit performance, and
seriously reduce component life time.
Please contact us if such products need to be carried.
• Perform a defrost of the eutectic plates at least once a week to ensure
an optimal efficiency of the eutectic system
Any excess of frosting lowers the efficiency of the eutectic
system.
• It is important to check the temperature of the product being loaded
to ensure that it is at the correct temperature for transport. The
refrigeration unit is designed to maintain the temperature of the product
at the temperature at which it was loaded; it was not designed to cool
a warm product.

• It is recommended to open doors as little as possible to avoid the intake
of hot air and humidity.
• Select the temperature by means of the thermostat, according to the
transported goods.
• Check the internal temperature of the goods being loaded (using a
probe thermometer).
•
• Leave a free space of about 6 to 8 cm between
load and front wall.
• Leave a free space of about 20 cm between
the top of the load and the roof.
• Load product on pallets (gratings) to provide
free air return to unit and improvement product
protection.
