rotating the boot to and fro. Fix into place using
the clamping ring and spanner provided. The
bottom of the boot should be firmly seated on
the top of the ACR tank. During the clamping
process silicone may bleed from the top of the
boot where the cable tail comes out. This is
normal and can be assisted by sliding a small
screwdriver into the boot alongside the cable
