Installation Checklist
When installing a 2500 ATG system on a Cone Roof Tank and Internal (Floating Roof) Pan
without a Floatwell, complete each installation step below. Check off a step when it is
complete. Refer to “Installation Schematics” on page 21 for overall dimensions.
Note Due to the resulting gross measurement inaccuracies, Varec does not recommend
that the perforated tape/tape cable be attached directly to a floating pan. Use a covered
floatwell for the best measurement accuracy.
