The following instructions must be read and understood before using this equipment. Failure to read and follow this
information may result in serious injury or death.
! WARNING
! CAUTION
!
!
These Installation, Operation, and Maintenance Instructions contain Important Safety Information. Only qualified
and properly trained personnel should apply, operate and maintain this Switch. Read and follow complete
Installation, Operation, Adjustment, and Maintenance instructions throughly before placing in operation.
This Switch is a unitized, three-phase, side break air disconnect switch. The Duogap
®
interrupter, when supplied,
makes the Switch a loadbreak switch.
Follow these instructions and the enclosed control drawing to install, operate
and maintain this Switch. The only area adjustable by the installation crew is the handle and lock segment.
Before beginning the installation procedure visually, inspect the switch for damage or missing parts. Compare your
switch with the enclosed control drawing. If damage from rough handling is evident, immediately file a claim with
the transportation company. Promptly contact the nearest Chance Sales Office for information regarding replace-
ment parts.

assemble a thru-bolt with washer behind the head
through the pole. Assemble a large curved pole washer
on the bolt and then screw a nut on. Draw bolt head and
washer up to approximately 1" from the pole. Lift
switch to desired level, then let switch down enough to
allow key hole slot in top of bracket to slide behind bolt
head and washer (as illustrated below). Tighten bolt
enough to pull bracket up to pole. Align bracket slot
with bottom thru hole, place washer under bolt head
and insert thru bracket and pole. Assemble curved
washer and nut/nuts and tighten all hardware se-
curely. Check for position and level. Assemble the pole
bands as shown on the control drawing and tighten
securely.
NOTE:Crossarm braces should be installed at this
time as required. Drill thru hole on centerline of pole
for crossarm brace bracket as required, (see control
drawing for dimension).

Step 5.
Remove all lift brackets at this time.
! WARNING
Failure to remove the lifting angles and brackets will
greatly reduce the basic insulation level, resulting in
switch flashover.

Switch mounting should be complete at this time,
NOTE:Deadending and terminal connections may be
made at this time. NOTE: It is recommended that all
terminal connections be cleaned (wire brushed) and
Chance contact sealing paste, “ZLN”, be applied be-
tween conductor and terminal and between terminal
and terminal pad on switch.
Proceed to section "B" for control mounting.

! WARNING
!
Resistance in the form of compression in reciprocating controls must be maintained in the closed position in order to
assure proper closing of the switch and to prevent creepage or accidental opening. See detail "A" for proper final
adjustment. Failure to do so could result in switch damage..
Step 1.
Remove all wire ties that are holding blades closed.
! WARNING
Failure to do so will result in damaging the switch.
!
Step 2.
Tighten handle clevis bolts or "U" bolts. (Do not
pierce yet). Open and close switch several times.
Inspect entire installation.
Step 3.
Final adjustment for reciprocating controls. (See
detail "A" below).
With switch in fully closed position with blades
against stops, loosen handle clamp hardware, pull
handle back approximately 15°-20° and retighten
clamp hardware. Push handle closed, a definite over-
toggle effect should occur. NOTE: If switch should
happen to not fully open with this setting, loosen
hardware and set handle approximately 15°. repeat
this procedure until switch has an over-toggle
compression in closed position and will still fully
open.
Step 4.
Tighten all hardware to 25-28 ft. lbs. torque. Pierce
set screws where applicable.

Step 2.
The arc bolt will slide along the arcing horn. The
blade tip casting (on the end of the blade) contacts and
moves the Duogap

lever toward the trip position.
If any phase of the switch does not operate as described above, contact the nearest A.B. Chance Sales Office.
Step 5.
When closing the switch, the arc bolt must contact
the arcing horn before the blade tip casting contacts
and wipes past the operating lever.
Step 6.
When the switch is fully closed, the Duogap

operat-
ing lever is free of the blade tip casting. There will be
a

Step 3.
The arc bolt separates from the arcing horn. The
Duogap

the current.)
Step 1.
The arc bolt should contact the arcing horn before
the blade leaves the spring contacts.
Step 4.
The blade tip casting slides free of the operating
lever. The blade moves to the open position and the
operating lever resets.

SECTION F. MAINTENANCE INSTRUCTIONS
Following a periodic inspection and maintenance
program will prolong the life of the Switch. The
Switch is designed for long-term exposure to all
weather conditions. However, certain environments
may reduce its life without some type of periodic
maintenance. Minimum inspection and mainte-
nance specifications have been established. Follow-
ing them will help ensure long service life.
NOTE: It is recommended that all overhead
switchgear go through a maintenance check at least
once a year, more frequent if switch is in a contami-
nated area.
Step 3.
Check for eroded contacts, alignment, and corrosion
of the hot parts. Replace any damaged components.
Lubricate all contacts and arcing horns with Dow
Corning FS-1292 silicone grease or equal.
Step 4.
Inspect all controls, interphase, and moving parts for
damaged or worn-out parts. Replace any damaged or
worn-out parts.
Lubricate all control components with A.B. Chance
silicone spray Cat. #C400-1749 or equal.
Step 5.
Check and tighten all thru bolts and mounting
hardware.
Step 6.
Inspect all pins, rivets, and bolted connections.
Tighten all hardware and replace damaged or worn-
out parts.
Step 7.
Check insulators for cracks, breaks or burns. Re-
place any damaged insulators.

closed. If not, readjust.
See Section B1 or B2.
Refer to ANSI C37.35 for additional recommenda-
tions. C37.35 is "IEEE Guide for the Application,
