Use only properly functioning lifting equipment to lift and lower the pump. Ensure that the pump does not become jammed during lifting and lowering. Do not exceed the maximum bearing capacity of the lifting equipment! Check that lifting equip- ment is functioning properly before use! WILO SE 2019-04... - Page 15 If necessary, use a lifting arm, to which the lift- ing gear can be vertically attached. ▪ Ensure the load is lifted vertically! ▪ Prevent the suspended load from swinging!

Page 16: Storage
▪ Mount the pump in a readily accessible place. This makes it easier to complete inspec- tions, maintenance (e.g. mechanical seal change) or replacement in the future. ▪ A travelling crane or a device for attaching hoisting gear should be installed above the set-up site of large pumps.

Page 17: Setting Up The Pump By Itself (Variant B, Wilo Variant Key)
The base must be able to support the unit installed on the baseplate indefinitely. The base must be level to ensure there is no tension on the baseplate or unit. Wilo recom- mends using premium, non-shrink concrete of an adequate thickness for manufactur- ing. - Page 18 This allows the screws to be moved in order to achieve their final positions. Wilo recommends initially pouring the base up to about 25 mm below the planned height. The surface of the concrete base must be well contoured before curing. Remove the pipe sleeves after the concrete cures.
