Electrical System - [M7 (-011 thru -016)]

With the power cord properly connected...Overheat ThermostatsCurrent (115 / 230 VAC) continuously flows thru the two (normallyclosed) overheat thermostats. This current supplies power to the timer.

If either thermostat opens (overheat or malfunction), voltage is removedfrom the timer until the thermostat is reset or replaced.

NOTEThe Manual-Reset Thermostat contacts open at approximately 285°F (140°C).To reset, allow unit to cool, then press RESET button on front of unit.

The Auto-Reset Thermostat contacts open at approximately 295°F (146°C).This thermostat automatically resets when the unit cools to approx. 265°F (129°C).

TimerCurrent is supplied to the timer thru the two overheat thermostats.

When the timer is turned ON...TimerThe (normally open) timer contacts close, and voltage is supplied to thetimer motor and the temperature regulator relay. The timer motor runs, andbegins to count down the time it was set for.(The contacts to the timer buzzer remain open).

Temperature Regulator RelayCurrent is supplied to the temperature regulator relay thru the timer. If thechamber temperature is lower than the temperature knob setting*, the relaycontacts are closed. When these contacts are closed, current flows thru therelay to the heating element and the heater light.

The diaphragm cup of the relay expands as the temperature & pressureinside the chamber increase. When the chamber temperature reaches thetemperature knob setting, the relay contacts open, and voltage is removedfrom the heating element & heater light.

[* The minimum temperature knob setting is approx. 220°F (104°C)]

When the timer is turned ON (continued)...Heater Light & Heating ElementWhen the contacts of the temperature regulator relay are closed,current is supplied to the heater light and the heating element.

As the relay contacts open and close, the heating element cycles ON / OFF.This continues until the timer setting expires.

The heater light is illuminated whenever the heating element is ON.

When the timer setting expires...Timer & Timer BuzzerThe contacts to the temperature regulator relay open, stopping the currentflow to the heater light & heating element.

The contacts to the timer buzzer close and current flows to the timer buzzer.When voltage is applied, the buzzer emits an audible signal.

The contacts to the timer motor remain closed for one minute. After oneminute the contacts to the timer motor & the timer buzzer open, stopping thecurrent flow to these two components.

As the relay contacts open and close, the heating element cycles ON / OFF.This continues until the timer setting expires.

The heater light is illuminated whenever the heating element is ON.

Bellows & Pressure Relief ValveHeat-Up:As the water in the chamber begins to boil, air is forced out of the chamber.This air passes thru the bellows into the reservoir.

Sterilization:When pure steam begins to flow thru the bellows, the bellows closesallowing pressure to build in the chamber. If the pressure in the chamberexceeds 34 psi (234 kPa), the pressure relief valve opens to prevent unsafeconditions.

AttentionThe door handle must be moved to the VENT position

before pressing the Fill / Vent Lever or Switch.

When the Fill / Vent Lever is pressed and held...Fill / Vent ValveThe (normally closed - manual) valve opens. Pressure forces waterand steam back into the reservoir thru the valve and the condensing coil.When all of the pressure has been vented, the door will "pop".

Note: Release the lever when the door "pops".If the lever is held too long, the chamber will begin to fill.

When the Fill / Vent Lever is released...Fill / Vent ValveThe valve closes.

Location & Function

As the water in the chamber begins to boil...Air & steam are forced out of the chamber,thru the open bellows, and back into the reservoir.

When pure steam begins flowing thru bellows...The bellows closes allowing pressure to build in the chamber.[Note: The bellows will periodically "hiss" or "spit", this is normal.

Location & Function

When the Temperature Control knob is adjusted...The flexible shaft rotates, increasing or decreasing the distancebetween the relay contacts. This adjusts the point (i.e. temperature)at which the relay contacts will open & close*.

As the temperature & pressure inside the chamber increase...The diaphragm cup expands, pushing the relay contacts apart.When the relay contacts are open, the heating element is de-energized.

As the temperature & pressure inside the chamber decrease...The diaphragm cup contracts, allowing the relay contacts to close.When the relay contacts are closed, the heating element is energized.
