WARNING
Electrical and grounding connections must comply with the applicable portions of the National Electrical Code
and/or other local electrical codes.
WARNING
Disconnect electrical power supply and place a tag at the disconnect switch to indicate you are working on
the circuit.
Water Supply Connection - Where Applicable
The incoming cold water supply connection, at the rear of the cabinet, requires 3/8” tubing and water pressure
of 25 to 50 psi. A manual shut-off valve must be provided convenient to the appliance; this valve should be open
when the appliance is in operation.
Drain Connection
The appliance drain (2” IPS) should be piped to a floor drain near the appliance. There should be no solid drain
connection; an “open gap” between the appliance and the floor drain is required.
WARNING
Plumbing connections must comply with applicable sanitary, safety, and plumbing codes.
Electrical Connections
When making electrical connections, use copper wire suitable for at least 200 °F (90 °C). The steamer must
be grounded in accordance with the National Electrical Code or applicable local codes. The wiring diagram is
located on the inside of the right panel.
Exhaust Hood
An exhaust system should be located directly above the steamer to exhaust steam and heat generated by the
steamer.

Example:
Total of above = 20 + 2.2 + 3 + 2.2 + 17 + 23 + 10 + 2.2 = 79.6 feet. Since each 10 feet is equivalent to 1 psi pressure
loss, 79.6 feet is equivalent to approximately 32 psi from an original boiler supply of 40 psi.
It is suggested that, wherever possible, the steam supply line
to the appliance is a separate line from the steam source.
If the appliance must be supplied from a line supplying
other appliances, the pipe sizes and pressure will have to
be veried. Further, during idle periods, when the steam in
the supply line is not in use, water will form from condensed
steam in the supply line. It is advisable to prevent water
pockets from forming in the steam line and impeding the
steam ow when it is required. Therefore, the steam supply
line should be installed level or run slightly downwards
towards the appliance. Install a Ball Float Trap near the
appliance to drain out water (condensed steam) from the line
to assure clean dry steam to the appliance.
Information to Steam Fitter
Each cooking compartment requires approximately 1 BHP (34.5 lbs. of steam per hour to operate satisfactorily. Therefore
a two compartment requires 2 BHP and a three compartment requires 3 BHP.
Assuming availability of a 30 psi supply steam pressure immediately to the appliance, then pipe sizes of 1/2”, 3/4” or 1”
will deliver respectively 90, 165 or 385 lbs. of steam per hour to the appliance Heat Exchanger. From the foregoing, a 1/2”
pipe line is not recommended.
An important consideration is the pressure drop that will occur through the steam supply line from its point of origin to the
appliance. The greater the length of piping and number of valves and elbows, the greater will be the pressure losses.
Consider a pressure drop of 1 (one) psi for each straight length of pipe equivalent to 120 diameters of that pipe.Thus, a 1”
pipe having a straight length of 120” (10 feet) is equivalent to 120 diameters of that pipe and will have a pressure loss of 1
psi through that pipe.
NOTE: In 3/4” pipe size, that a Standard 90° Elbow and Angle Valve and a Globe Valve are equivalent to 1.8 feet,
10 feet and 18 feet respectively of straight pipe.
Similarly, in a 1” pipe size, a standard 90º Elbow and Angle Valve and a Globe Valve are equivalent to 2.2 feet, 12
feet and 23 feet respectively of straight pipe.

Direct Steam Compartment Cookers Operation
Steaming
Each steaming compartment is controlled by its own controls. When a compartment is not operating, the drain is open and
the steam inlet valve from the boiler is closed. Food, properly portioned and in appropriate solid or perforated pans, is placed
on rack supports (or wire shelves) in the steaming compartment. After closing and sealing the door, setting the timer, and
pulling out the operating handle, the steam inlet valve from the boiler opens, allowing steam at a pressure of 6 psi to enter
the compartment. Air from the sealed compartment exits through the vent until the temperature reaches 180 °F; then the vent
closes and the compartment can become pressurized. [On DDA models only, if the top compartment has been switched to
pressureless steaming, steam enters the compartment and is exhausted to the drain without pressurizing the compartment.]
Steaming continues until the timer reaches “0” and the buzzer sounds. To silence the buzzer, push in the operating handle.
Wait one minute for steam or hot water to drain away. Open the door and remove the cooked food.
The cabinet (lower portion of steamer) contains the pressure regulator. On DDA models there is also the drain assembly,
water cooling valve, power switch, pilot light and drain thermostat.
PREHEAT COMPARTMENTS
If the cooker has been standing idle and the compartments are cold, preheat before loading.
General
Turn on power and steam supply to appliance. DDA Models open left door of cabinet and turn on Power Switch. Pilot light
will come ON indicating power to the condensate valve and drain thermostat.
Shut Down
Turn o power switch and steam supply to appliance.

Cooking Guidelines
The cooking guidelines in this manual are suggestions only. You should experiment with your food products to determine
cooking times that will give you the best results. Variables which aect cooking time include size, weight, thickness of foods,
temperature, density, previous condition of the foods (fresh, pre-blanched or frozen) and degree of doneness desired.
To allow steam to circulate around the pans, food must be spread evenly throughout the pans. Best results are obtained after
the compartments are allowed to preheat. When all compartments are to be loaded at the same time, it is best to allow the
rst compartment to reach 4 - 4.5 psig before starting the next compartment. When processing frozen vegetables, use half
the suggested pan weights and allow sucient time for cooking doneness.
