This procedure outlines the steps you must complete to prepare
a GC for use in another country or to configure for a different
oven heating speed.
Procedure
1 Select the appropriate power option kit. See Power options (
257). Compare the parts listings for the present and new
power option to see what must be replaced.
Select the appropriate power cord. See Power cords ( 396).
Cool down the oven.
Turn off the GC main power switch and disconnect its power
cord.
Hazardous voltages are present in the
mainframe when the GC power cord is connected.
Avoid a potentially dangerous shock hazard by
disconnecting the power cord before removing
any GC panels.
Components can be damaged by static electricity:
be sure to wear an ESD strap grounded to the GC
chassis while performing this procedure.
If necessary, replace the oven shroud. See Replacing the oven
shroud, oven fan, and oven fan motor ( 205).
