TROUBLESHOOTING THE QUICKCHILLER

The QuickChiller is a stand alone, high capacity refrigeration system used to rapidly and uniformly lower

the temperature of a hot food product through the “chill danger zone.” There are five Quickchiller models

consisting of the QC3, QC20, QC40, QC50, and QC100. All models share the same basic electrical and

electronic components.

ELECTRICAL INSTALLATION

Basic installation must be made on a level, load-bearing surface and must have a drain available for

condensate. The electrical requirements are either 208VAC or 240VAC single-phase. All units are shipped in

the 240 VAC default setting. THE SUPPLY VOLTAGE MUST BE VERIFIED BEFORE HOOKUP.

If the supply voltage is 218 to 245 VAC, no changes are needed. If the supply voltage is less than 218 VAC

the leads of the transformer must be changed. Locate and remove the transformer orange lead from the

transformer to the terminal block. Remove the wire nut from the transformer red lead and install it on the

terminal block in the same location from which the

orange wire was removed. Install the wire nut on the

orange wire and secure it. Once again verify the power

supply matches the transformer setup. Once the power

supply is connected, the unit circuit breaker, which is

mounted on the relay board enclosure, must be

switched

ON.

MICROPROCESSOR CONTROL

The Alto-Shaam Quickchiller has a microprocessor

control panel, which utilizes a menu screen to guide

the operator through all operation mode sequences.

The main menu screen should appear in the control

display (Figure 1). If the Main Menu screen does not

appear, the control display will show “SYSTEM

INITIALIZED” and an audible alarm will sound for 30

to 60 seconds. THE QUICKCHILLER SHOULD BE

LEFT IN THIS CONDITION FOR A PERIOD OF

TWO (2) MINUTES.

After waiting 2 minutes, turn the Quickchiller

circuit breaker

OFF for 30 seconds. Turn the

Quickchiller circuit breaker back ON and the Main

Menu screen will appear on the display.

QUICKCHILLER SET-UP SCREEN

From the Main Menu screen, press and hold the “1” key

for 5 seconds. The Software Version screen (Figure 2)

will appear. NOTE: YOU MUST VERIFY THAT THE

QUICKCHILLER IS PROGRAMMED TO THE

SPECIFIC UNIT MODEL NUMBER. After verifying

the programmed model number is correct, press the

“D” key to return to the Main Menu screen.
