NOTE - Test mode lasts for 30 minutes (with the
temperature updating every 30 seconds) except for the
defrost test, which lasts 30 seconds. Tests feature
provides the technician time to manually verify the
equipment operation.
The tests feature is available after set up has been
completed once. After you touch next in the final set up
screen, the "select tests to run" screen (figure 16) will
appear. (If you want you may skip tests; touch skip
tests.)
To run all of the tests, touch select all. All boxes in the list
of tests will be checked. Or, touch box(es) next to test(s)
to run certain tests.
After the tests have been started, the screen will
describe which test is running and show a diagnostic
summary of each test (see figure 17). After reviewing the
results and concluding that no further tests are needed,
touch next to proceed to next test. The technician must
verify that the test procedure is producing the desired
result at the equipment.
After pressing next after the final test, the Testing
finished screen will appear (figure 18). At this point, use
the EXIT button (if you have completed the required set
up), or use diagnostics button (to analyze the system),
or use equipment button (if you wish to make any
changes to device details).
