WARNING: Do not puncture the skin of the Staging Cabinet with any tools or fastening devices. Electrical shock or component damage could result.

The staging cabinet should be placed on an approved table or shelf to allow easy access for loading and unloading of product. For proper operation, the cabinet must be level.

Electrical Connection

The Staging Cabinet is available from the factory as a 120 VAC unit for domestic use, or as a 240 VAC unit for foreign use. The data plate on the side of the unit will specify the correct electrical supply. The unit requires a grounded receptacle with a separate electrical line protected by a fuse or circuit breaker of the proper rating.

WARNING: The cabinet must be adequately and safely grounded according to local electrical codes to prevent the possibility of electrical shock.

Cabinet Preparation

When the cabinet is turned on for the first time, you may experience the following:

A.A burning odor.

B.Slight smell of smoke.

This indicates oils used on stainless steel and the new electrical connections are burning off residue.

It will take 3 to 4 hours of burn off to eliminate this inconvenience. The burning off procedure should be done the day before you intend to use the cabinet. It should be done in a ventilated area away from the kitchen and customers. After the burn off procedure is complete, thoroughly clean the staging cabinet following the daily cleaning procedures.
