3. TRANSPORT AND STORAGES
• Wear safety shoes and gloves for handling!
• Observe the weight data on the type code.
• Do not transport the fan by the connecting cables!
• Avoid impacts and collisions, especially on fans set-up on devices.
• Watch out for possible damage to the packaging or fan.
• Store the fan in the original packaging in a dry area protected from the weather or protect it from dirt and
weather until nal installation.
• Avoid exposure to extreme heat and cold.
• Avoid excessive storage periods and inspect the motor bearings for proper operation prior to installation.
4. MOUNTING
• Do not loosen the impeller, fan or balancing weight. Installation and electrical connection should only be
carried out by trained and qualied personnel. Wear safety shoes and gloves for handling!.
• The installation and security information are harmonized with the valid standard and guidelines
(DIN EN ISO 12100 / 13857).
• Avoid structural damage or stress with installation. Make sure the surface is at and even.
• Ensure the clearance gap between the impeller and the casing is maintained. Distortion due to uneven
surface may lead to fan failure due to bushing against the fan wheel. A minimum head gap “A” of 2.5mm
in all installation positions is necessary.
• Protective measures must be taken against falling parts when mounting with a hanging rotor.
• In the case of a vertical motor axis the respective lower condensation drain hole must be open (does not apply
to protection class IP55 fans).
• Make sure condensation drain-holes of the motors are not blocked.
• Connect fan only to electrical circuits that can be disconnected with an all-pole isolating switch.
Electrical connection corresponding to connection diagram a) in terminal box and b) by cable design connection
diagram on cable or on wall ring.
