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.
EconoCraft steamers are identified by model number 24-CET-l. Each character of
the model number identifies a characteristic of the steamer. The EconoCraft is a
Convection steamer, .Electric powered,and Table-mounted with an input energy
rating of 8 kW. This manual covers all standard features of model 24-CET-l
EconoCraft steamers. Figure 1-1 illustrates the Econo-Craft and identifies the
major components.
During manufacture, EconoCrafts are assigned serial numbers. A typical
EconoCraft 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 are
used when explaining differences in design, parts, or operation among units with
the same model number. For example: a particular part may be used on all 24CET-l steamers with serial numbers before WC -7350-90G-02, and a different pan
used on 24-CET-l steamer WC-7350-90G-02 and all those manufactured after it.

Electric Power Requirements
The characteristics of the electric power supply must match the power
requirements specified on the EconoCraft Product Information Plate. The plate is
located on the left side of the unit.
Water Quality Requirements
As with any steam generating equipment, poor water quality degrades EconoCraft
performance. If feed water is low in Total Dissolved Solids (TDS) and free of
paniculate matter, the steam generator, hearing element, and valves of the
EconoCraft will give years of trouble-free service with a minimum of
maintenance.
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 and other impurities which remain behind as lime or scale deposits
during the steam generating process. These deposits have caused many
components to fail. including heating elements, probes, and solenoid valves. Of
equal importance, lime and scale deposits decrease the efficiency of heat transfer
which causes increased water and power consumption. EconoCraft use in areas
with poor water quality requires installation of a SteamerGard water treatment
system or increased frequency of maintenance, cleaning, and descaling.
Check the quality of feed water before starting construction of the water supply
lines. If a SteamerGard water treatment system must be installed 10 achieve
acceptable water quality, install it before running the water supply lines to the
EconoCraft.
Contact a local water treatment specialist for an on-the-premises water analysis.
The recommended minimum feed water quality requirements for the EconoCraft
are listed in Table 2-2.
• If analysis shows that the supply water is within me required limits, a single
water connection can be installed as illustrated in Figure 2-13.
• If analysis shows the supply water within required limits and a hot water heater
is desired for preheating water to the steamer, install as illustrated in Figure 2-
14. DO NOT install with hot water to the condenser inlet. The condenser
supply must be cold water for proper operation of the steamer.
• If analysis shows that the supply water is NOT within the required limits, a
SteamerGard water treatment syst em and two water supply lines must be
installed as illustrated in Figure 2-15.
• 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 31).
• Always connect a cold water supply to the EconoCraft water supply lines. DO
NOT USE HOT WATER. The steamer will not function properly or withi n
design safety limits if hot or warm water is supplied to either the condenser
connection or the steam generator fill connection.

Minimum Feed Water Quality Requirements
Total Dissolved Solids less than 60 parts per million
Silica less than 13 parts per million
Alkalinity less than 20 parts per million
ph factor greater than 7-5
Softened, Treated, or Filtered Water
Do not use softened or chlorinated water in the EconoCraft steam generator.
If the water supply is treated or softened either by the water company or on
the premises, it may contain chlorine or various salts. These additives are
damaging to the EconoCraft steam generator. Salts used to soften water
cause rapid scale buildup, and increased corrosion.
Some water treatment plants kill bacteria in the water by adding chlorine.
Chlorinated water is actually dilute hydrochloric acid. It is very damaging to
the EconoCraft. When healed in the steam generator, chlorinated water
rapidly dissolves generator walls and heater elements. In extreme cases,
poisonous and highly corrosive chlorine gas is released in the steam generator.
Installing a high volume, charcoal or reverse osmosis, water filtering system
removes most of me salts and chlorides introduced by water treatment and
softening. Contact a local water treatment specialist or the local water
company for assistance with chlorinated water.
Figure 2-4. Equipment Stand
When selecting an operating location for the EconoCraft, observe me following criteria.
• The EconoCraft uses a minimum of counter space. Figure 2-5 illustrates
the dimensions and clearances required. The 3-inch clearance at the rear
includes spacing for the water inlet and fittings, and the maximum size (11/4-inch NPT) drain fittings.
• Note in Figure 2-5 that a 3-inch clearance is required above the
EconoCraft. Do not store articles on top of the unit.
• The EconoCraft weighs approximately 100 pounds. The counter area
selected must be capable of supporting an operational weight of
approximately 120 pounds to include the weight of wat er and food.
• The EconoCraft has capacity for one 12"x20" x25" Cafeteria Pan (model #
SP-2.5 or PP-2.5). Convenient storage for pans should be considered
when selecting the operating location.
If a satisfactory counter location is not available, consider using a model ES2424 Equipment Stand. This stand, illustrated in Figure 2-4, is designed to
support the EconoCraft, and meets the above criteria-

Install Four Legs
Do not install the EconoCraft without legs.
1. Place the EconoCraft on its left side.
2. Check that the feet are fully retracted into the legs. Do not overtighten, the feet
should easily screw in and out by using fingers only.
3. Install all four (4) legs in the bottom of the EconoCraft
4. Turn the steamer upright.
Position and Level EconoCraft
For efficient operation, the steamer should be level both front to back and side to
side. The legs of the EconoCraft are four inches long when the adjustable feet are
fully retracted. The adjustable feet can be extended approximately two inches,
providing adjustment for leveling the steamer.
1- Refer to the Installation Check List, Table 2-1. Check that all Preparation
Tasks arc complete. Check that all Unpacking and Assembly tasks are
complete.
2- Place the EconoCraft at the location where it will be used.
3- Adjust the retractable feet of the Econocraft to level the unit.
Install and Conne ct the Free Air Vented
Drain Lines
The drain outlet discharges exhaust steam and hot condensate from the steamer.
The drain outlet MUST be free air vented to equalize the pressure in the
EconoCraft with me atmosphere. Generating steam causes pressure to increase in
the unit: cold water flow into the condenser creates a vacuum (low pressure) in the
condenser. Without a free air vent, either high or low pressure in the compartment
will cause malfunction or damage. The openings at me top of the vent pipe and
drain outlet provide the EconoCraft with free air venting.
• Pressure build up in the steamer will cause steam and hot water leakage around
the door.
• A vacuum WILL implode the steamer and cause permanent physical damage.
Furnishing and installing the fittings and drain line is the responsibility of the
owner and/or installer. Figure 2-7 illustrates a drain layout recommended by
Cleveland Range. Observe the following instructions 10 determine the pipe size,
the number of fittings required, and the layout of the drain line path.
