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.
