SteamerGard Water Treatment System
ASteamerGard water treatment system protects the SteamCraft 10 from impurities contained in regular
lap water, especially Total Dissolved Solids (TDS) which cause lime and scale deposits in steamer
equipment. The protection is so effective that Cleveland Range increases toe warranty coverage on a
Steam Craft 10 installed in conjunction with a SteamerGard system to five years for parts and three years
for labor on water related components, elements, valves, generators, piping, etc. However, even with a
SteamerGard system installed, the owner/user should follow toe guidance of the Warranty Protection
Table.

Steam Craft 10 Service Manual

Models 24-CGA-10, 24-CGP-10, 24-CEA-10, 24-CEP-10 SteamCraft 10 Service Manual, Chapter 1 Page 1
CHAPTER 1. PRODUCT IDENTIFICATION
Cleveland Range, Inc. assigns two product identification numbers to each
SteamCraft 10: a model number and a serial number. The model number
identifies the product characteristics. The serial number identifies the indi-
vidual unit.
MODEL NUMBER The operating section of this manual (Chapters 1 through 4) covers four
models of the Steam Craft 10 steamers:
•Gas fired atmospheric generator 24-CGA-10
•Gas fired pressure generator. 24-CGP-10
•Electric atmospheric generator. 24-CEA-10
•Electric pressure generator 24-CEP-10
The service section of this manual (Chapters 5 through 8) covers only the
atmospheric models:
•Gas fired atmospheric generator 24-CGA-10
•Electric atmospheric generator. 24-CEA-10
Each character of the model number identifies a characteristic of the
steamer. The Steam Craft 10 is 24 inches wide; a Convection steamer,
Electric or Gas powered, Atmospheric or Pressurized steam generator, and
has the capacity for 10 cooking pans.
This manual covers all standard features and options available on
SteamCraft 10 steamers. Other than selection of options, there are
presently no significant design, parts, or operating differences among
steamers with the same model number. Figure 1-2, Sheets 1 through 4
illustrate the four SteamCraft 10 models and identify the major components.
SERIAL NUMBER During manufacture, SteamCraft 10's are assigned individual serial num-
bers. A typical SteamCraft 10 serial number is: WC-7350-90G-02. The left
half of the number carries design information. The right half of the number
contains the manufacturing date and the unit of the manufacturing lot The
date of our sample number is 90G-02:90=1990, G=July. 02=the second unit
of the manufacturing lot Serial numbers arc used when explaining differ-
ences in design, parts, or operation among units with the same model
number. For example: a particular part may be used on SteamCraft 10's
with serial numbers before WC-7350-90G-02, and a different part used on
steamer WC-7350-90G-02 and those manufactured after it.
PRODUCT INFORMATION PLATE
The Product Information Plates list the unit's model and serial numbers, and
power and wiring requirements. These plates are located on the left side
panel, in the lower right corner. Figure 1-1illustrates typical SteamCraft 10
Product Information Plates. Refer to me Figure 1-2for the location of the
plates.
