Page 7: Receipt And Inspection Of Goods
Installation and Maintenance SFL/M COLLECTION AND INSPECTION OF GOODS The receipt and inspection of the delivered fans should be carried out in accordance with the following guidelines: When receiving the goods, please check all delivery documents against the products received before removing any packaging. - Page 8 Cable glands and conduits should be positioned to prevent moisture from collecting on the gland gasket - the gland entry must not face vertically upwards. In case of any doubts regarding the fan equipment, please contact the Smay technical department before installation.
- Page 9 Installation and Maintenance SFL/M GUIDELINES FOR INSTALLATION OF FAN ACCESSORIES Flexible connections/compensators Flexible connectors enable mechanical isolation of the fan shafts from adjacent ducts. Flexible connections should not be used to compensate for poor channel fit. Maximum allowable channel mismatch: <Ø1000 mm = 5 mm axially...
- Page 10 Installation and Maintenance SFL/M Ribbed rubber base liners should be used whenever vibration isolators are mounted on concrete or other rough surfaces. Please note that vibration isolators are not designed to compensate for angular misalignment, excessive horizontal forces, or tensile forces, and cannot be used in applications with tensile or shear loading.

Page 11: Start-Up Instructions
Installation and Maintenance SFL/M An optimal distance between the fan inlet and the nearest obstacle should be ensured, equal to at least one fan diameter; even then, the fan capacity may be lower than the rated capacity. In the case of demanding installation places where there is not much space, such as expansion chambers, it is necessary to strictly observe the minimum distances of fan inlets from obstacles and other devices. -

SMAY Service or an Authorized SMAY Service. Damage to SFL/M fans resulting from failure to comply with the guidelines contained in the documentation will not be subject to warranty repairs. -
Page 13: Appendix 1 - Maintenance Schedule
For more demanding environments where vibration and shock are common, maintenance must be performed more frequently. If in doubt, please contact Smay. The activities should be performed at least as often as in the table below and are the basis for the proper operation of the device. - Page 14 Installation and Maintenance SFL/M ANNEX II – Troubleshooting Observations Potential causes Comments Mechanical damage to the rotor. Uneven accumulation of dirt on the impeller. Vibrations during operation Unbalanced rotor Hostile environment causing corrosion or deterioration of the impeller. Ice build-up in low temperature applications.
