In standard applications, you mount the control to a surface through holes in the back of the case.
Important: On rough
mounting surfaces use the top two mounting holes only. When these controls are mounted
on an uneven surface using screws in all four holes, the case can be twisted enough to
affect the control’s calibration and operation.
NOTICE
You can install the control with or without a bulb well assembly. For closed tank applications without a well assembly, order the Part No. FTG13A-600R packing nut assembly.
