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.
