After the anchor filling mortar has completely cured the frame should be levelled
with a space between block and lower frame flange of 3 - 5 mm*. This space is
necessary for levelling using the base frame adjusting bolts with metal washers
(not included). The base frame should be levelled on each frame side. Adjust the
frame on each adjusting place until all frame sides are horizontal.
This space largely depends on the sort of grout or mortar used. Determine this
space according to the instructions of the grout or mortar supplier.
Finishing with a self-levelling grout
After levelling has been completed the adjusting bolt ends must be greased to
avoid bonding to the self-levelling grout. The space between concrete block and
frame must be completely filled with the self-levelling grout to ensure that the
complete bottom surface of the base frame will be supported. Therefore, it is not
allowed to use shims between concrete base and base frame.
