I. SPECIFICATIONS

1. FEATURES

[a] FLOOR MOUNTING OR FIXED MOUNTING
The floor mounting and fixed mounting options are available. Use the rotary Select Switch
provided on top of the Operation Panel to choose between the two options. If the fixed mounting
option is selected, the Bin Control Switch in the Control Box will become functional.

[b] BIN CONTROL ADJUSTMENT (Fixed Mounting Only)

The sensitivity of the Bin Control Switch in the Control Box is factory-adjusted for the standard
Storage Bin B-500. If requested by the customer, it is adjustable by turning the Adjust Screw on
the Bin Control Switch. See "4. BIN CONTROL ADJUSTMENT" in the installation manual for
further details.

[c] ICE PRODUCTION CONTROL (Fan Control)

The ice production will increase at low ambient or water temperature. As a result, the Gear
Motor will have a higher torque to harvest ice, and the icemaking mechanism will be overloaded.
To prevent this condition, the icemaker controls the Fan Motor rotation speed to keep the
discharge pressure in the refrigeration circuit within a proper range.

[d] OVERLOAD PROTECTION

Despite the above-mentioned ice production control, some use conditions (water quality etc.)
or variable part tolerances may overload the icemaking mechanism. A photomicrosensor will
detect overload by reduction in Drum rotation speed and shut down the icemaker. This can
avoid a costly breakdown of the icemaking mechanism or the like.

[e] USER RESET

When a protector trips to shut down the icemaker, an error code will be displayed. If it is a
resettable error, the user can restart the icemaker by pressing the Reset Button accessible from
the Window Panel and continue the icemaking operation until a service person arrives. Some
errors are non-resettable or repetitive and require troubleshooting by qualified personnel.

[f] ERROR CODES AND RECORDS

When the icemaker shuts down with an error, the Display Window will show an error code "E_".
A maximum of eight most recent records are memorized and can be checked at the time of
service or inspection.
