• The minimum height between the lifting hook and the floor must be sufficient to lift the unit. Contact a Xylem representative for more information. • The lifting equipment must be able to hoist the unit straight up and down, preferably without the need for resetting the lifting hook.
2 Transportation and Storage 2. Lift the pump by using the correct lifting equipment. 3. Put the pump upright on a rigid horizontal surface so that it cannot fall over. 4. Cut the transportation strap. 2.3 Temperature ranges for transportation, handling and storage Handling at freezing temperature At temperatures below freezing, the product and all installation equipment, including the lifting gear, must be handled with extreme care.
2 Transportation and Storage Unit in as-delivered condition If the unit is still in the condition in which it left the factory - all packing materials are undisturbed - then the acceptable temperature range during transportation, handling and storage is: –50°C (–58ºF) to +60°C (+140ºF). If the unit has been exposed to freezing temperatures, then allow it to reach the ambient temperature of the sump before operating.
• Modifications to the unit or installation must only be carried out after consulting with Xylem. • Original spare parts and accessories that are authorized by Xylem are essential for compliance. The use of other parts can invalidate any claims for warranty or compensation.
