Equipment Description
Your 3-pan, 5-pan or 10-pan boilerless steamer is designed to give years of service.
It has a stainless steel cavity (cooking chamber) which is served by an electric heated
atmospheric steam generating reservoir. A powerful blower circulates the steam in the
cavity to increase heating efficiency.
Each cavity holds up to three, five or ten steam table pans (12” x 20” x 21/2” deep) as
shown below.

An 18-guage stainless steel case encloses the cavity, the steam generating reservoir
and the control compartment that houses electrical components. Door hinges are
field-reversible (the door may be set to open from the left or right). Operating controls
are on the front panel.
The boilerless steamers are equipped with fully electronic controls. These units are
readily identified by their unique control panels. Steamer function is controlled by
touch pad controls and a rotary timer-dial. The drain system on all models includes a
spray condenser, which cools drain water.

Inspection & Unpacking
CAUTION
SHIPPING STRAPS ARE UNDER TENSION
AND CAN SNAP BACK WHEN CUT.
Your boilerless steamer will be delivered completely assembled in a heavy shipping
carton strapped to a skid. On receipt, inspect carton carefully for exterior damage.
Carefully cut the straps and detach the sides of the carton from the skid. Pull the carton
up off the unit. Be careful to avoid personal injury or equipment damage from staples
which might be left in the carton walls. Write down the model number, serial number and
installation date. Keep this information for reference. Space for these entries is provided
at the top of the Service Log in the back of this manual.

Installation
WARNING
THE UNIT MUST BE INSTALLED BY
PERSONNEL WHO ARE QUALIFIED TO
WORK WITH ELECTRICITY AND PLUMBING.
IMPROPER INSTALLATION CAN CAUSE
INJURY TO PERSONNEL AND/OR DAMAGE TO
THE EQUIPMENT. THE UNIT MUST BE
INSTALLED IN ACCORDANCE WITH
APPLICABLE CODES.
CAUTION
DO NOT INSTALL THE UNIT WITH THE REAR
VENTS BLOCKED OR WITHIN 2 INCHES
OF A HEAT SOURCE SUCH AS A BRAISING
PAN, DEEP FAT FRYER, CHARBROILER OR
KETTLE. TO AVOID DRAINAGE PROBLEMS,
LEVEL THE UNIT FRONT TO BACK, AND
PITCH SLIGHTLY TO THE FRONT.
CAUTION
EACH UNIT MUST HAVE A SEPARATE
GROUND WIRE FOR SAFE OPERATION.
WARNING
TO AVOID DAMAGE OR PERSONAL INJURY,
FOLLOW THE WIRING DIAGRAM EXACTLY.
Minimum Clearances: Boilerless steamer requires the following minimum clearances
to any surface, combustible or noncombustible.
Right Side 2 inches
Left Side 2 inches
Rear 6 inches
Steam Free Zone: The boilerless steamer can be damaged by steam from external
sources. Do not install the steamer over a steam venting drain. Ensure that steam is
not present in an area bounded by the footprint of the steamer and a circle 18 inches
in radius about the right rear corner of the steamer (see figure at left).

Rated Current Demand Per Cavity (Amperes)
1. Electrical Supply Connection
Current and power demands for each unit are as shown above.
A. Panel Removal - Right Side
Open the wiring and control panel by removing screws from the right side
panel. Slide the panel forward and set it aside.
B. Supply Voltage
The unit must be operated at the rated name plate voltage. The name plate
can be found on the rear of the unit.
C. Phase Selection
Refer to steamer wiring diagram and element wiring on pages 19 and 20
for wiring information.
D. Terminal Block
The terminal block for incoming power is located at the back of the control
compartment. The ground terminal is located in the wiring compartment
near the terminal block.
E. Supply Wire
The equipment grounding wire must comply with the National Electrical
Code (NEC) requirements. The wiring diagram on the inside of the unit’s
right side cover gives directions for proper connection of the terminal block
jumpers. The wire must be used or the unit will not meet Underwriters
Laboratories and NEC requirements. The electric hole is sized for a oneinch conduit fitting.
F. Branch Circuit Protection
Each boilerless steamer, including individual units of stacked models,
should have its own branch circuit protection and ground wire.

Installation
WARNING
DO NOT CONNECT THE DRAIN DIRECTLY
TO A BUILDING DRAIN. BLOCKING THE
DRAIN IS HAZARDOUS.
CAUTION
DO NOT USE PLASTIC PIPE. DRAIN MUST BE
RATED FOR BOILING WATER.
IMPORTANT
DO NOT ALLOW WATER TRAPS IN THE LINE.
A TRAP CAN CAUSE PRESSURE BUILD-UP IN
THE CAVITY, WHICH MAY CAUSE THE DOOR
GASKET TO LEAK.
WARNING
DO NOT STACK STEAMERS WHEN
LEGS ARE USED.

3. Water Connection(s)
Install a check valve to prevent back flow in the incoming cold water line, as
required by local plumbing codes. Water pressure in the line should be between
30 and 60 PSI. If pressure is above 60 PSI, a pressure regulator will be needed.
These pressures must provide the 1.5 gallons per minute required for proper
steamer function.
A 3/4 inch female NH connector (garden hose type) is used to attach the water
supply to the inlet valve. Minimum inside diameter of the water feed line is 1/2
inch. Use a washer in the hose connection. Do not allow the connection to leak,
no matter how slowly. Do not over-tighten hose connections.
This equipment is to be installed to comply 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).
4. Drain Connection
Level the steamer front to back, and pitch it slightly to the front (maximum 1/4
inch) by adjusting the optional legs or the bullet feet on the optional stand.
There must be a free air gap between the end of the hose and the building drain.
The free air gap should be as close as possible to the unit drain. There must also
be no other elbows or other restrictions between the unit drain and the free air gap.
Install the drain line with a constant downward pitch.
Proper Drain Line Connection: Drain line must have a constant downward pitch of at
least 1/4” per foot. Observe local code regarding air gap spacing and drain connections.
5. Factory-Stacked Units
This section is applicable only if you are installing factory-stacked units.
Installing stacked steamers is similar to installing a single unit. The steamers are
stacked and assembled at the factory and delivered with the water connections
and drain hoses required for a single point connection.
6 OM-SBC-E
A. Water Connection
The same water supply connection is used for both units. At the water inlet
valve a 3/4 inch female NH connector (garden hose type) is used for the
water supply.
B. Electrical Supply Connection
Separate electrical connections will be required for each steamer to be
stacked. Each steamer unit must have it’s own branch circuit protection.
C. Drain Connection
Steamers must be leveled front to back, and pitched to the rear (maximum
1/4 inch) by adjusting the bullet feet on the cabinet or stand base. For all
factory-stacked steamers, a 2-1/2 inch ID hose is attached to the unit
drain. It must be rated for boiling water.
6. Counter-Mounted Units
This section is applicable if the steamer will be mounted to a counter. All four
edges of the bottom of the steamer must be sealed with RTV to the counter if the
4 inch legs are not used. Counter must be made of a noncombustible material
such as metal or tile.
Initial Start-Up
WARNING
WHEN YOU OPEN THE DOOR, STAY AWAY
FROM STEAM COMING OUT OF THE UNIT.
STEAM CAN CAUSE BURNS.
After the boilerless steamer has been installed, test it to ensure that the unit is
operating correctly.
1. Remove all literature and packing materials from the interior and exterior of the
unit.
2. Make sure the water supply line is open.
3. Turn on electrical service to the unit. The steamer will not operate without
electrical power. Do not attempt to operate the unit during a power failure.
NOTE: The door MUST be closed for the elements to operate.
4. To turn unit on, press the ON switch on the control panel.
5. When the steam generating reservoir has filled with water, the heaters will begin
heating automatically. Within 20 minutes or less the READY light will come on,
indicating that the water has reached its standby temperature. When the READY
light is displayed, you may take any one of the following steps:
a. Push TIMED and set the timer knob to the desired steaming time.
b. Push MANUAL for continuous steaming.
c. Push STOP to let the unit stay at ready condition.
6. To shut down the unit, press the OFF switch. The steam generating reservoir will
then fill with cold water and drain.
7. If the steamer operates as described, the unit is functioning correctly and ready
for use.
