5.2Mounting on a fixed roof tank
There are three methods for mounting the 4532 ATC on a fixed roof tank:
•Top anchor method
•Thermo well method
•Anchor weight method
If the tank bottom has a heating coil, the clearance from the flexible tube bottom hook to the tank bottom may increase depending on the heating coil type.
5.2.1Top anchor method
The flexible tube is stabilized by a wire hook and a top anchor.

Caution! The flexible tube must be lowered carefully without bending too much and scratching at the inner edge of the nozzle hole.
2.Rotate the 4532 ATC so that you can set up the cabling in the most convenient way.
3.Straighten the tensioning wire, fix the wire end to the top anchor temporarily and lower the wire.
