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.
