GL0016P-02 Installation Guidelines for BioDisc
®
Units BF, BG, NF & NG
7
5.10 BG and NG BioDisc have an off-set centre of gravity and should not be lifted by the base channels as
this would risk tipping over the unit. The old slinging points are still in the bottom of the mould, they are
not to be used under any circumstances. Lift using the 4 new metal lifting brackets as indicated by
labels on the unit.
