Replacement of Switching Elements
 Disconnect electrical power to the defective switching element and unhook wires from
screw terminals, or wire leads (if installed) from junction box.
Failure to disconnect electrical power before performing these procedures
could result in severe personal injury or death.
 Remove two switching element mounting screws. (See photo.)
 Remove the defective switching element and discard.
 Loosen the overtravel locking screw. Do not remove. (See photo.)
 Use an awl or sharp tool to remove filler material from the overtravel adjustment slot,
insert flat blade screwdriver into slot and turn to open the switching element mounting
bracket, i.e. move it away from the piston. Lightly tighten the overtravel locking screw.
 Check that switching element bracket is securely mounted to housing. There must be
no movement between the bracket and the housing.
 All insulation must be replaced exactly to ensure the safety of the product.
NOTE: Switching Element Bracket design and con guration may vary slightly depending upon date
of manufacture, housing, number of switching elements, etc. Check the micro switch mounting
screws and the overtravel locking screw to determine the type of screwdriver(s) required for this
procedure:
 No. 6 Gulmite screwdriver
 Torx head screwdriver
 1/4” Hex nutdriver
 Phillips head screwdriver
 Position replacement switching element on the bracket so the actuator pin aligns with
the piston. Use a threaded-locker adhesive on screw threads. Insert the switching
element mounting screws and tighten securely to 10 in-lbs.
 Perform overtravel adjustment (See page 4).
