User Manual

3 OM-SSB-3E/5E/10E & (2)SSB-3E/5E/10E Domestic
THE AREA DIRECTLY AROUND THE APPLIANCE MUST BE CLEARED OF ALL
COMBUSTIBLE MATERIAL. FAILURE TO FOLLOW THESE INSTRUCTIONS CAN
CAUSE BODILY INJURY AND/OR PROPERTY DAMAGE.
The steamer must be disconnected from the gas supply system during any
pressure testing of that system which has test pressures in excess of 1/2 PSI
(3.45 kPa).
B. Electrical Supply Connection
CAUTION: EACH UNIT MUST HAVE A SEPARATE GROUND WIRE FOR SAFE
OPERATION.
WARNING: TO AVOID DAMAGE OR PERSONAL INJURY, FOLLOW THE WIRING
DIAGRAM EXACTLY
1. 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.
2. 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.
3. Phase Selection
Refer to steamer wiring diagram and element wiring at the end of this
document for wiring information.
4. 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.
5. 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 one-
inch conduit fitting.
6. Branch Circuit Protection
Each SmartSteam100 Boilerless Steamer, including individual units of
stacked models, should have its own branch circuit protection and ground
wire.
C. 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.
Dual water connection: 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).
NOTE: Local code may also require check valves in the water supply line.
D. Drain Connection
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.
Level the steamer front to back, and pitch it slightly to the rear (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 restrictions between the unit drain and the
free air gap.
Install the drain line with a constant downward pitch.
IMPORTANT: DO NOT ALLOW WATER TRAPS IN THE LINE. A TRAP CAN
CAUSE PRESSURE IN THE CAVITY, WHICH MAY CAUSE THE DOOR GASKET
TO LEAK.
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.
E. 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.
