CHAPTER 1 PRODUCT IDENTIFICATION

Cleveland Range, Inc. assigns two product identification numbers to each steamer: a model number and a serial number. The model number identifies the product characteristics. The serial number identifies the individual unit.

A. MODEL NUMBER

This manual covers the Gemini Model No. 24CGA6.2 and 24CGA10.2 Dual Steam Generator and Convection Steamer.

Each character of this model number identifies a characteristic of the steamer. The Gemini Model No. 24CGA10.2 is 24 inches wide, a Convection steamer, Gas powered, and an Atmospheric steam generator with a capacity for 10 cooking pans, this model has the extra suffix “.2” to differentiate it from our standard 10 pan model that does not have two separate generators. This manual covers all standard features and options available on Gemini gas steamers.

4) Do not install any heat producing equipment near the air vents of the equipment. Do not block the air vents of the unit. Do not store articles on top of the unit.

5) Figure 2-1 and 2-2 illustrate the dimensions and clearances required for these steamers. Maintain the following minimum dimensions around the unit for safe and efficient operation, maintenance and service.

6) The steamer must be level both front to back and side to side. Select an operating surface that is level enough to allow leveling the unit without extreme adjustment of the legs.

7) The location selected must be capable of supporting 650 lbs. for a Gemini steamer. This includes the weight of the water and the food.

Malfunctions and equipment damage may result from improper mounting. Malfunctions and/or damage resulting from improper mounting are not covered by the equipment warranty.
