INTRODUCTION
DESCRIPTION
Models SCX-2 and SCX-10, convection steamers mounted on cabinet base and a steam coil
boiler, designed to ASME Code and approved as a steam boiler restricted to operation at
pressure not to exceed 15 psi. SCX-2 steamer has a pan capacity of 6 (2-1/2") pans, SCX-10
cooker has a pan capacity of 10 (2-1/2") pans.
BASIC FUNCTION:
The sequence of operation is as follows:
1. Turn on main power switch. Pilot light will indicate main power is on and steam generating
will begin. In approximately 20 minutes, sufficient amount of pressurized steam will have
been generated in the heat exchanger and ready pilot light will come on. OFF shuts off the
steam supply to the boiler and opens the automatic blowdown valve, if so equipped,
emptying the boiler and releasing water and steam to the drain. The manual blowdown
valve will have to be opened to drain if not equipped with automatic blowdown valve.
2. Boiler pressure gauge should read 9 - 11 psi during operation, 0 psi during shutdown.
3. Compartment cooker is ready for use when READY light is on. Place pans of food to be
cooked into compartment(s) and close door(s).
4. Set timer(s) to cook time desired. Cooking will commence and cooking time may be
interrupted at any time by opening door(s) and resumed again by closing door(s).
5. Buzzer will sound indicating the end of the cooking cycle and that steam has stopped
entering the compartment(s). The COOKING pilot will go off and the READY light will come
on. Buzzer must be shut off by turning the timer(s) to its off position.

1.0 INSTALLATION INSTRUCTIONS
GENERAL
The steam boiler is designed to ASME Code and approved as a steam heating boiler restricted
to operation at pressure not to exceed 15 psi.
INSTALLATION
UNPACKING
Immediately after unpacking, check for possible shipping damage. If the appliance is found to
be damaged, save the packaging material and contact the carrier within 15 days of delivery.
Before installing, verify the electrical rating agrees with the specification on the rating plate.
LOCATION
Position the appliance in its installation location. Check that there are sufficient clearances to
service the controls, door swing, etc. Also adequate clearance must be left for making the
required supply and drain connections.
Allow enough space between any other piece of equipment or wall for service access. Service
to the controls may be required on the left and/or right side panels of the cabinet.
INSTALLATION CODES AND STANDARDS
The appliance must be installed in accordance with:
In Canada:
Provincial and local codes, or in the absence of local codes, with the Canadian Electric Code,
CSA C22.1 (latest edition). Copies may be obtained from the Canadian Standard Association,
178 Rexdale Blvd., Etobicoke, Ontario, Canada, M9W 1R3.
In the U.S.A.:
State and local codes, or in the absence of local codes, with the National Electrical Code,
ANSI/NFPA-70 (latest edition). Copies may be obtained from The National Fire Protection
Association, Batterymarch Park, Quincy, MA, 02269.

1.0 INSTALLATION INSTRUCTIONS (Continued)
Ideally an exhaust system should be located directly above the appliance to exhaust steam and
heat generated by the appliance.
1. Set the unit in place and level using a spirit level.
2. Ascertain that a floor drain (open gap) is convenient to the appliance drain.
3. Mark hole locations on floor through anchoring holes provided in flanged adjustable feet.
4. Remove appliance and drill holes in locations marked on floor and insert proper anchoring
devices.
5. Set unit back in position and re-level left to right and front to back.
6. Bolt and anchor appliance securely to the floor.
7. Seal bolts and flanged feet with Silastic or equivalent compound.
8. Make service connections as indicated.
WARNING: Electrical and grounding connections must comply with
applicable portions of the National Electrical Code and/or other local
electrical codes.
WARNING: Disconnect electrical power supply and place a tag on
the disconnect switch to indicate that you are working on the circuit.
Use copper wire suitable for at least 200 degrees Fahrenheit (90 degrees Celsius). The
steamer must be grounded. The wiring diagram is located on the inside right hand panel as
you face the steamer.

2.0 INFORMATION TO STEAM FITTER
1. Assuming availability of 30 psi supply steam pressure immediately to the appliance, then
pipe sizes of ½" or 3/4" or 1" will deliver respectively 90, 165 or 385 lbs. of steam per
hour to the appliance Heat Exchanger. From the foregoing to use ½" pipe line would
most likely prove inadequate.
An extremely 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.
