Insert The Unit Into The Tank; Figure 15: Auxiliary Float Switch Height Adjustment - ABB LevelMaster 7100 User Manual

IMPORTANT NOTE: Once the desired switch float position is verified or corrected, the switch assembly is ready to
be inserted in the tank with the LevelMaster. The height of the auxiliary switch can be adjusted later by loosening
the nut on the fitting installed on the top side of the tank port bushing (Figure 15). The tubing can be pulled up
providing a range of approximately 9 inches.
When the tubing is slid all the way down, the switch will actuate at approximately 12 inches below the bottom of the
tank port bushing for the 12 inch switch, and at 16 inches below the bottom of the tank port bushing for the 16 inch
switch.
IMPORTANT NOTE: If applicable, plumb the conduit or cable into the conduit box for the high level switch.
Terminate the wiring inside the conduit box using wire nuts. There are two wires coming from the switch
representing the two sides of the switch. There are no polarity considerations.

IMPORTANT NOTE: The following procedures are for both, general-purpose installation or hazardous location
installation, unless otherwise noted.
CAUTION – Equipment damage. Failure to follow these procedures may cause damage to the LevelMaster.
To install the LevelMaster in the tank:
IMPORTANT NOTE: The insertion of the LevelMaster typically requires at least two people, as the length and
weight of the LevelMaster can make it very difficult or impossible for a single installer to handle. The ideal situation
incorporates the use of a crane. The following procedure assumes no crane.
