CONNECTING MULTI-FUNCTION BLOCKS
Sealing strip is supplied loose and must thus be fitted before the blocks
are connected together. See Fig. 4 and 5.
JOINTING OF BLOCKS
Internal bolted joints at the bolt lugs fitted along the frame are used for
jointing the blocks to one another. Access to the inside of the casing can
be gained either by opening an inspection door or by removing a wall
panel. Some of the unit sections, such as the filter section, may be
dismantled for better access.
1. Fit the sealing strips supplied to the frame of one of the blocks.
2. Push the blocks towards one another, making sure that they are well
lined up with one another.
3. Fit the joint bolts into the corner brackets on the inside of the frame and
make sure that they are firmly in position.
4. Tighten all four bolts alternately, compressing the seal to 1–2 mm, see
the figures below.
