3. OPERATING CONDITIONS
3.1 Intended conditions of use
Fans are machines designed for moving air to control temperature and humidity in greenhouses or rearing sheds by
extraction, not under pressure. They can even be installed horizontally, without altering or modifying their characteristics.
Normal ambient temperature limits are -15°C to +40°C. Maximum altitude is 1000m above sea level. Should a fan be
required to operate at a higher altitude, the loss in mass flow (heat removing capacity) due to lower air density should be
taken into consideration.
The fan has been designed and built to operate in safety for the user, if used according to the conditions intended by the
manufacturer and stated in this user and maintenance manual.
NOTE
For further information, please refer to the technical documentation attached to this manual.
3.2 Non-permitted conditions of use
Total or partial failure to observe the instructions given in this manual could cause damage to the fan and/or people.
The following uses are to be considered not permitted and improper:
• use in the event of faults and/or tampering with the installed safety devices;
• use by personnel not specifically trained;
• installation of the fan for extraction or circulation under pressure;
• use contrary to existing regulations;
• incorrect installation differing from instructions given in this manual;
• supply from an electrical network with characteristics different from that specified in the wiring diagram;
• total or partial failure to observe instructions;
• insufficient maintenance;
• use of non-original spare parts;
• use of lubricants with characteristics different from those specified in the technical documentation attached to the
manual;
• use by minors;
• use under the influence of drugs, alcohol, etc.
WARNING Use of the fan other than as described in the user manual or outside the operational limits laid down
by the manufacturer is considered IMPROPER USE. In the event of IMPROPER USE the manufacturer declines
all liability in relation to any damage that may be caused to persons or property, and any kind of warranty will be
considered invalidated.
