Figure 7.8.4 The screws lifting the drum marked blue.
The rear drum lifter is opeated in the same way as the front drum lifter, but instead of one screw
placed in the center of the drum, there is now two screws lifting the drum.
Tighten one screw at the time, and lift the drum slowly by taking turns on the two screws so that
the drum is being held close to the centreline of the filter during the entire process.
7.8.2 Lifting the drum on filters with tank
The procedure for lifting the drum on a filter with tank is the same as for the frame version of
the filter.
On the inlet side of the filter the drum lifter can be accessed by lifting the center flooring tile
marked blue in figure 7.8.5.
On the effluent side of the filter the plate marked blue in figure 7.8.6 must be removed to access
the drum lifter.
