MAINTENANCE PROCEDURES
After determining the problem, the cause must be determined and the proper procedure
followed. Following are the proper maintenance procedures:
A. To replace a switch:
1. Eight bank units: Lay the unit on its back. Remove the base of the unit. This
allows access to the switches. Loosen the screws holding the wires, and then
remove the screws holding the switches in place using a 5/64" Allen key. After
bending the lever on the new switch (See Below - "D"), install the new switch.
Make sure the wires are connected to the proper terminals, then replace the
base and tighten all the screws.
2. Ten bank units: Remove eight (8) screws holding the face panel in place and
carefully lower the face panel. Do not pull any wires loose from their
connections! Lay the unit on its back to allow easier access to the switches.
Loosen the screws holding the wires, and then remove the screws holding the
switches in place using a 5/64" Allen key. After bending the lever on the new
switch (See Below - "D"), install the new switch. Make sure the wires are
connected to the proper terminals, and then replace the face panel.
