3: REPLACING PARTS

The AST2225-3 transfer switch mechanism has been designed to allow all components to

be accessible and readily removable from the front of the back panel.

CAUTION When replacing any parts of the mechanism, isolate the transfer switch from

any possible source of power.

All AST2225-3 transfer switch mechanism hardware should be tightened sufficiently

before re-energizing the switch. The following table provides suggested tightening

torques.

NOTE: For satisfactory performance, the switch terminal lugs must be securely fastened

to the terminal strips-90 (in-LB min.) Torque lugs screws to 200 (in-LB).

Replacement parts should be identified with reference to the Parts List on page 8 and the

Assembly Drawing on page 13. All parts are available direct from the factory. Be sure to

state the model and serial number of the switch. These are located on the arm label.
