and, as a consequence, to too high temperature and condensation pressure and a decrease in
the efficiency of the entire device. The compressor then works under overload conditions and in
extreme cases it can lead to permanent damage to the refrigerant unit. For these reasons, it is
recommended to:
–
Ensure good ventilation of the store room.
–Do not install the device in a place exposed to direct exposure of sunlight.
–
Be sure to keep the openings ventilation holes devices, free from closures
or obstacles.
–Periodic (frequent) checking of condenser unit condition
–
Setting the refrigeration unit away from heat sources (e.g. radiators, etc.)
and in a place not exposed to sunlight
–
Do not setting the furniture in the immediate operating range of the fans
(e.g ceiling fans, air conditioner fans).
It is forbidden to set or install the device near external ignition sources.
