INTRODUCTION

DESCRIPTION

Models SB-6SC and SB-10SC convection steamers mounted on 24” cabinet base and a
steam coil boiler. An optional 36” cabinet is available for these models. Model SB-16SC
convection steamers mounted on 36” cabinet base and a steam coil boiler. All bases
are designed to ASME Code and approved as a steam boiler restricted to operation at
pressure not to exceed 15 psi. SB-6SC steamer has a pan capacity of 6 (2-1/2") pans.
SB-10SC has a pan capacity of 10 (2-1/2") pans. SB-16SC has a pan capacity of 16 (2­1/2") 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.
