SteamCraft 5.1: a model number and a serial number. The model number
identifies the product characteristics. The serial number identifies the individual
unit.
All-SteamCraft 5.1 steamers are identified by the same model number,
21-CET-16. Each character of this model number identifies a charac teristic of the steamer. The SteamCraft 5.1 is a Convection steamer,
.Electric powered, and Table-mounted with an input energy rating of 16.5
kW. This manual covers all standard features and options available on
SteamCraft 5.1 steamers.
Other than selection of options, there are presently no significant design,
parts, or operating differences among steamers with this model number.
Figure 1-1 illustrates the SteamCraft 5.1 and identifies the major components.
During manufacture, SteamCraft 5.1's are assigned individual serial
numbers. A typical SteamCraft 5.1 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 manufac turing 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 SteamCraft 5.1's with serial numbers before WC-7350-90G-02, and a
different part used on steamer WC-7350-90G-02 and those manufac tured
after it

INSTALLATION DIAGRAM NOTES
1. The Product Identification Plate located on the back
panel specifies the electric power requirements.
2. For each unit, the installer must provide a ground
connection and a separate fused disconnect switch.
3. Catastrophic damage will result from shifting the
SteamCraft 5.1 more than 10° out of level while
power is turned on at the unit's main power switch.
4. The unit must have a cold water supply, NOT HOT.
The water supply must meet the quality requirements
of Table 2-2, and the pressure requirements on page
18.
5. A SteamerGard system is recommended when water
quality does not meet the Table 2-2 requirements.
Figure 2-1. Schematic Installation Diagram
6. A manual shut off valve must be installed between
the main water supply and the steamer supply fines.
Refer to figures 2-18 and 2-19 for the recommended
component arrangements.
7. Run a single water fine between the main cold water
supply and the tee. The separate steam generator
and condenser/blowdown supply fines are
comparatively short.
8. The drain One must have a gravity flow away from
the steamer, and must not be connected to the dram
lines of any other equipment.
9. The drain line must be free air vented- If the line

Water Quality Requirements
CAUTION
PREPARATION FOR INSTALLATION
Before unpacking the SteamCraft 5.1, check the electric power and water quality
requirements and select the operating location-
Electric Power Requirements
requirements specified on the SteamCraft 5.1 product identification plate.
The plate is located on the back of the unit as illustrated in Figure
2-2.
Using water not within the limits specified in this manual could
void or adversely affect Cleveland Range's warranty
coverage of the SteamCraft 5.1.
As with any steam generating equipment, poor water quality degrades
SteamCraft 5-1 performance. If feed water is low in Total Dissolved Solids
(TDS) and free of particulate matter, the steam generator, heating element,
and valves of the SteamCraft 5.1 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. Th ese deposits
have caused components to fail, including heating elements, probes and
solenoid valves. Of equal importance is the decrease in heat transfer
efficiency caused by lime and scale deposits. Decreased heat transfer
increases water and power consumption. Use of the SteamCraft 5.1 in
areas with poor water quality requires installation of a SteamerGard water
treatment system or increased frequency of maintenance, cleaning, and
descaling.

Position and Level
The SteamCraft 5.1
The SteamCraft 5.1 is typically counter top mounted on four adjustable
legs. To compensate for height limitations, the steamer can be surface
mounted directly to the counter top. If a suitable counter is not available,
the unit can be secured to a Cleveland Range ES-2130 Equipment Stand.
The following instructions cover each of these mounting methods.
CAUTION
Malfunctions and equipment damage may result from
improper mounting. Malfunctions and/or damage
resulting from improper mounting are not covered by the
equipment warranty.
The SteamCraft 5.1 MUST BE LEVEL BOTH FRONT
TO BACK AND SIDE TO SIDE in all mount ing
arrangements.
Catastrophic damage will result from shining the
SteamCraft 5.1 more than 10° out of level while power is
turned on at the unit's main power supply switch.
Leg Mounting and Leveling
The supporting legs of the SteamCraft 5.1 are four inches long when the
adjustable feet are fully retracted. This provides the four inch space below
the unit required by NSF sanitary standards. The adjustable feet can be
extended approximately two inches for leveling the steamer.
Assembly
1. Check that the feet are fully retracted into the legs. Do not overtighten. The feet should easily screw in and out using fingers only.

Surface Mounting and Leveling
WARNING
INJURY AND EQUIPMENT DAMAGE could result
from improper lifting. The SteamCraft 5.1 weighs
approximately 135 pounds. Use enough workers with
experience lifting heavy equipment to place the
SteamCraft 5.1 on the counter.
2. Be sure electric power is turned off at the main power switch. Place
the SteamCraft 5.1 on its left side.
3. Screw the four legs into the weldnuts mounting holes - All four lees
must be installed for proper mounting of the SteamCraft 5.1.
4. Place the steamer upright on its four legs.
Positioning and Leveling
1. Thoroughly clean the counter top area that will support the steamer.
2. Using a level, determine and mark the highest comer of the counter
top area that will support the steamer.
3. Lift the SteamCraft 5.1 into position on the counter.
4. Do not adjust the retractable foot of the leg in the highest comer
(marked in step 2). Using a level, adjust the other three legs until the
unit is level both front to back and side to side.
5. After the SteamCraft 5.1 has been positioned and leveled, refer to
page 14, and install the slide racks.
Figure 2-8. Counter Top Mounting Holes
When a SteamCraft 5.1 is surface mounted (without legs), NSF standards
require a sanitary counter top seal between the counter surface and the
bottom of the unit. This seal closes any gap between the unit and counter
top. A sanitary seal closing a gap greater than 1/4 inch may not meet NSF
sanitation standards. Therefore, do not surfac e mount the SteamCraft 5.1
to a surface out of level more then 1/4 inch over the length or width of the
unit. Shimming the unit level may leave a gap too large to seal within NSF
standards.
1. Thoroughly dean the bottom perimeter of the steamer and the counter
top area that will support the steamer.
2. Using a level, determine and mark the highest comer of the counter top
area that will support the steamer- At each of the other three comers,
measure and note the shim thickness required to level the SteamCraft
5-1 both front to back and side to side.
3. Refer to Figure 2-8. Leaving the required clearance (shaded area)
around the unit, determine the exact front, back, and side lines of the
SteamCraft 5.1 on the counter top. From these lines, locate and drill
four 1/2 inch diameter mounting holes in the counter, as shown in the
diagram.
Page 12 Model 21 -CET-16 Service Manual
4. Lift the SteamCraft 5.1 into position on the counter and align the
steamer mounting holes with the counter mounting holes. The steamer
mounting holes are the holes with the 3/8" -16 weldnuts usually used to
mount the adjustable legs -
NOTE: If there is not enough clearance behind the steamer to install the
5. Install 3/8"-16 mounting screws and washers as shown in Figure 2-9.
The screws should be long enough to pass through the washer,
counter, shims, and weldnut without projecting more than 1/2 inch
above the weldnut. Thread the screws only a few turns into the
weldnuts, leaving enough play for leveling the unit and sealing the
mounting holes -
6- Do not shim at the highest corner (marked in step 2). Shim the ot her
three comers until the unit is level both front to back and side to side.
7. Inject enough silicone sealant into each mounting hole in the counter to
seal the hole as the hardware is tightened.
8. Tighten the mounting hardware enough to secure the unit in place but
not change the level. After hardware is tightened, verify that the
SteamCraft 5.1 is level front to back and side to side.
9. Seal the gap between the SteamCraft 5.1 and the counter top. Lay a
generous bead of silicone sealant under the entire perimeter of the

Drain Lines
DEATH, INJURY, AND EQUIPMENT DAMAGE could
result from improper installation of the drain outlet lines.
Improper installation of these lines could void the
SteamCraft 5.1 warranty. The following restrictions are
critical to the safety of personnel and equipment, and
must not be violated under any circumstances.
Do not connect the drain fine into PVC pipe, or any other
drain material that cannot sustain 180° F.
Do not connect drains from any other equipment to the
SteamCraft 5.1 drain line.
Do not connect the drain outlet extension line directly to a
floor drain or sewer line.
Furnishing and installing the drain line is the responsibility of the owner
and/or installer. Figure 2-13 illustrates a drain layout recommended by
Cleveland Range. Observe the following instructions to determine the
pipe size, the number of fittings required, and the layout of the drain line.
Model 21-CET-16 Service Manual Page 15
NOTE: The drain line must be free air vented, have gravity flow
from steamer, and terminate outside the perimeter of the
unit
The one inch minimum clearance between the drain opening
and floor drain provides the SteamCraft 5.1 with free air venting.
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 SteamCraft 5.1 with the
atmosphere. Without a free air vent, either high or low pressure
in the compartment will cause malfunction or damage.
• 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
damage.
Figure 2-13. Drain Lay out
1. The drain lines must be installed in compliance with the Basic Plumbing Code of the Building Officials and Code Administrators International, Inc. (BOCA), and the Food Service Sanitation Manual of the
Food and Drug Administration (FDA).
2. The tot al length of pipe and number of bend fittings required to reach
the open drain determines the pipe size used to extend the drain line
to an open drain.
• If the drain outlet extension requires six feet or less of pipe, and no
more than two elbows are required, use 1-1/4-inch pipe and fittings.
• If the drain outlet extension requires six to twelve feet of pipe, or
requires three or more elbows, use 2-inch pipe and fittings -
3. The drain line must have a gravity flow from the SteamCraft 5.1 drain
outlet to the floor drain. Do not install a trap in the drain line.
4. Free air venting requires a minimum of one inch clearance between
the end of the drain line and the top of the floor drain.
5. Do not connect the steamer drain to drains or plumbing of any other
equipment. If drains of two or more units are connected together
• Low pressure can develop, causing an implosion and physical
collapse of the steamer-
• Drainage from another unit can flow back into compartment of the
steamer.

Install Water Supply Lines
owner and/or installer. This section illustrates plumbing layouts
recommended by Cleve land Range. When installing water supply lines,
observe the following instructions.
1. Always connect a cold water supply to the SteamCrart5.1 water supply
lines.DO NOT USE HOT WATER. The steamer will not function properly
or within design safety limits if hot or warm water is supplied to either the
condenser connection or the steam generator fill connection.
2. Supply water must have a minimum dynamic pressure of 35 psi (2.4
kg/cm2) and a maximum static pressure of 60 psi (4.1 kg/cm2). If static
pressure exceeds 60 psi, a pressure regulator must be installed in the
supply lines. For best results, set the regulator for 50 psi dynamic
pressure. Water pressure greater than 60 psi will cause damage to the
solenoid valves. Local water pressure can be 100 psi or more. If
possible, check supply pressure at non-peak demand time. A local water
company can assist in this check.
3. Refer to the recommended plumbing layouts in Figures 2-18 and 2-19,
and install the water supply lines and fittings in accordance with all local
and national codes. Pay particular attention to the following
requirements and recommendations.
Model 21 -CET-16 Service Manual Page -19
