Figure 16: Tank Port Bushing Installation - ABB LevelMaster 7100 User Manual

CAUTION - Equipment damage. If the tank has an operating agitator or mixer, it should be turned off before
attempting to insert the LevelMaster assembly. Leaving it in operation could cause harm to the equipment.
a. Remove the bull plug from the top of the tank.
b. Clean the threads on the tank opening.
2. While keeping the LevelMaster in the horizontal position:
a. Slide the float(s) and tank port bushing all the way to the bottom of the casing to ensure that the floats do not slide
down when the unit is raised vertically.
b. Slide the cord connector all the way to the bottom of the casing. Loosening the connector may be required so that it
can slide through the casing with no resistance.
3. Raise the LevelMaster vertically.
4. Ensuring that the float(s) are still all the way at the bottom of the casing, lift the unit and move to the top of the tank.
5. Once on top of the tank, carefully feed the casing and float(s) through the tank port opening.
6. Slowly lower the LevelMaster assembly and allow the unit's weight to keep the unit vertical. If the bottom of the tank has
sludge, the unit may need to be worked up and down a few times to allow the unit to be properly seated.
7. Screw the tank port bushing into the tank opening and tighten (Figure 16). If the 24 inch version of the high level switch
was purchased, ensure that the tubing is assembled and that the offset points away from the casing.
8. Ensure all fittings are tight except for the fitting on the top side of the tank port bushing.
9. Slide the cord connector down and screw into the tank port bushing.
