2.3 START-UP TEST

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.
