Operation (Single door models):
The electric defrost
controller is preset at the factory to provide a defrost cycle
every 6 hours (4 defrosts per day). If it is necessary to change
the number of defrosts due to unusual operating conditions,
it can be accomplished by adjusting switches 7, 8 and 9 as
shown above.
