CHAPTER 1. PRODUCT IDENTIFICATION
Cleveland Range, Inc. identifies products by two numbers: a model number and a serial number. The model number identifies the product characteristics. The serial number identifies the individual unit
SteamCraft V steamers are identified by model number CET-16. Each character of the model number identifies a characteristic of the steamer. The SteamCraft V is a Convection steamer, Electric powered, and Table mounted with an input energy rating of 16.5 KW. This manual covers all standard features of model CET-16 SteamCraft V steamers. Figure 1-1 illustrates the SteamCraft V and identifies the major components.
During manufacture, SteamCraft V's are assigned serial numbers. A typical SteamCraft V serial number is: WC-7350-89G-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 July, 1989:89= 1989, G=July. 02=the second unit of the manufacturing lot.
Serial numbers are used when explaining differences in design, parts, or operation among units with the same model number. For example: a particular part is used on all CET-16 steamers, with serial numbers before WC-7350-89G-02, and a different part is used on CET-16 steamer WC-7350-89G-02 and all those manufactured after it
Presently, there are no significant design, parts, or operating differences
among model CET-16 SteamCraft V steamers.

PREPARATION FOR INSTALLATION
Before unpacking and positioning the SteamCraft V, select and prepare the installation site. This section of Chapter 2 details selection of the SteamCraft operating location, and preparation of that site with power, water, and drain lines .
Water Quality Requirements
As with any steam generating equipment, water quality is a critical factor in SteamCraft V performance. If Seed water is tow in Total Dissolved Solids (TDS) and free of particulate manner, the steam generator, heating elements, and valves of the SteamCraft V will give years of trouble-free service with a minimum of maintenance .
CAUTION
VOID WARRANTY
The use of steam generator feed water not within the limits specified in this section of the manual could void equipment warranties.
In some areas, even potable tap water contains a variety of impurities that can cause costly problems in steam generating equipment. Of primary concern are mineral salts, IPS, which remain behind as line or scale deposits after the water has boiled away as steam. These deposits have caused a variety of components to fail, including heating elements, probes, and solenoid valves. Of equal importance is the toss of energy efficiency due to line or scale buildup. In these areas, either a Steamer­Gard water treatment system must be installed, or time frequency of maintenance, cleaning, and descaling must be increased.
It is critical to know the quality of the feed water before starting con­struction of the water supply fines. If a SteamerGard water treatment system must be installed to achieve acceptable water quality, it should be installed before running the water supply lines to the SteamCraft V.
Contact a local water treatment specialist for an on-the-premises water analysis. The recommended minimum feed water quality requirements for the SteamCraft V are listed in table 2-2.
• If analysis shows that the supply water is within the required limits, a
single water connection can be installed as illustrated in figure 2-2.
• If analysis shows that the supply water is NOT within the required limits, a SteamerGard water treatment system and two water supply lines must be installed as illustrated in figure 2-3.
• If analysis shows that the supply water is NOT within the required limits, and it is not possible to install a SteamerGard water treatment;
plan on increasing the frequency of maintenance, cleaning, and descaling beyond that recommended in the maintenance schedule
(Chapter 4, page 37).
