2.3.1 With the chiller door closed, test the door
buzzer and door switch by entering the hold
cycle. Press "B" on the keyboard when the
Main Menu screen appears on the display. The
compressor will become audible. After a
period of 60 seconds, open the unit door. A
buzzer should sound and the display will
prompt the operator to close the door.
2.3.2 Close the door and allow the unit to operate
for approximately 10 minutes. Verify the
operating time with the timer which appears in
the upper right-hand corner of the Hold Mode
display screen. If the timer does not indicate
the correct amount of time, begin the SET-UP
procedure once again.
2.3.3 With the food probe(s) remaining in the
appropriate holder (no product) verify a
decrease of the temperatures appearing in the
display. The temperatures displayed should
start at the approximate room temperature and
decrease from that point. If any of the
temperatures displayed are above 120°F (49°C),
considerably above normal room temperature,
contact the Alto-Shaam Service Department.
2.3.4 Following the 10 minute test operation period,
press "D" on the keyboard to exit the hold
mode. Open the unit door and make certain
the interior walls of the unit are cold.
