Transport, storage

Transport

WARNING: Observe enclosed safety instruction sheet. Fasten transport equipment (cables, chains etc.) only at the two ring nuts.

NOTICE: During transport, ensure that the impeller is not knocked or distorted. Never fasten transport equipment to the motor, directly to the weather protection hood or impeller. Ensure that the impeller can rotate freely around its axis during transport and that there are no foreign bodies hampering movement.

Ensure that the two ring nuts are securely tightened for transport.
Attach suitable transport equipment to the two ring nuts.
Position fan on the roof at the installation site using a crane.

Storage

Only store fans in a dry location and resting in a horizontal position on the metal base (at -20 °C to +60 °C). Avoid storage periods that are too long.
Protect the fan from impact that could damage it.
Do not store the fan in an environment containing corrosive substances.
Avoid the impeller remaining idle for long periods (both in storage and when already installed). During idle periods, regularly turn the impeller by hand and check that it can move freely to prevent damage to the bearings. Failure to comply with these requirements releases the manufacturer from all guarantees and liability.
Before installation, check that the moving parts (impeller, shutters) can move freely.
Do not store the fans in the vicinity of running and vibrating machinery. This would expose the impeller bearings to excessive strain, which could result in imbalance during operation.
If stored for lengthy periods, protect the fans from dust, moisture and sunlight.
