MS Component Description & Function
Generator: Also known as a heating plate, it is a circular shaped aluminum casting consisting of a permanently
integrated heating element. When powered, it generates heat to convert a shot of water (approximately ¾-1oz 25-30
ml) into steam instantaneously.
NOTE: Theses generators come in 120, 208, & 230 volt versions & are voltage specific. They must operate on
the proper voltage supply, otherwise, they are prone to premature failure. NOTE: All generators are artificially
seasoned (Limed) at the factory. A mixture of water, baking soda, & lime, is poured onto the generator
surface to steam away & formulate a thin layer of calcium buildup. A thin layer is always needed for proper
steaming characteristics. See “Monthly Maintenance” section.
Generator Lid:
A circular shaped, gasket less lid that is secured onto the generator with a wing nut. Allows the
steam to be forced down through the generator steam ports, & onto the product.
Generator Diffuser Plate: A circular shaped plate with many small orifices. Helps contain & prevent loose particles
from being directed onto the food product.
Chimney: Located at the rear of the unit, it allows excessive steam in the food compartment to exit the steamer
from the rear, & also allows the condensation to drain into a drip tray below it.
Thermocouple: A type “K” consisting of 2 wires, Red (-) & Yellow (+). One end plugs into the control board &
the other is inserted into a hole in the generator. As it monitors the internal generator temperature, it generates & relays
DC millivolts to the control board (See Millivolt Chart). NOTE: At the control board, the thermocouple connector
plugs into 3 male pins. The center pin is positive (+) & MUST always align with the yellow wire. The two outer
pins are negative (-) & either one must align with the red wire.
Hi-Limit: A capillary tube style, normally closed temperature switch that monitors the internal generator temperature.
If the heating circuit fails & runs away, the hi-limit will trip (Between 550-590 F (287-310 C), & open the generator
circuit. NOTE: If the hi-limit trips, the reset button must be manually pressed to reset it. If at any time a hi-limit
trips, the root cause must be determined & corrected.
