Installation procedure

All parts should be inspected for damage before using. If 

there is evidence of physical damage, the unit should not be 

installed unless approved by your Eaton representative.

Bolt-in assembly

ote:

N

The tank wall should have a 1.325 (34 mm) diameter 

hole with an anti-rotation key, (refer to Figure 8). 

Switch should be located to ensure recommended 

clearances in Figure 6 are maintained.

1.  Switch should be mounted to four (4) couplings on the 

inside of the tank wall (refer to Figure 6 for coupling 

pattern) using 3/8" x .75" (10M x 19 mm, if metric 

couplings are being used) long bolts with lock washers, 

(not supplied).

2.  Install the gasket over the switch shaft sealing gland 

and insert the switch assembly through the tank hole. 

Position the switch with the open sides of the switch 

block facing down and to a side.

3.  Align the switch mounting plate holes with welded 

bosses and install the 3/8" x .75" (10M x 19 mm) 

long bolts with lock washers. Tighten bolts to the 

recommended torque, (refer to Table 4).

4.  Install Plastic Mounting Nut over the externally protrud-

ing threaded sealing gland and tighten plastic mounting 

nut (refer to Table 5). (Sealing is accomplished with 

O-rings on the operating shaft and gasketed sealing 

gland secured on the outside of the tank with locking 

nut).

5.  (Optional) install spring (small end toward end of shaft) 

and limit plate over the shaft.

6.  Install handle onto the switch shaft with the stainless 

steel hex socket cap screw and lock washer supplied 

and tighten to recommended torque in Table 4.

CAUTION 

The areas around the mechanisms and contacts do not 

contain user adjustable parts and should not be altered 

during installation.

CAUTION 

Bolt-In Assembly switches are dependent on proper 

location and use of couplings welded to the inside 

of tank. A reliable system of fixturing and gauging is 

essential to successful mounting of switch.
