1.3 Equipment Description
Frymaster Electric Cookers are specifically designed to deliver high volumes of cooked or blanched
food automatically.
Model Comparison:
8SMS: The “Spaghetti Magic System” features an 8-kilowatt cooker and rinse tank
combination. The 8.7-gallon (33-liter) cooker is equipped with a programmable computer
that controls water temperature, water level, and cooking times. A swing-away water faucet
is standard. Its automatic basket lift system submerges and extracts either bulk or
individualized portions of pasta according to times programmed by the operator. Options
include automatic water filling (AutoFill) and starch skimming (AutoSkim). The AutoFill
feature maintains the cookpot water level approximately 1¼ inch (32mm) below the
overflow drain. The AutoSkim feature sprays water onto the surface of the water, forcing
starch to the overflow drain. This eliminates loss of cooking time associated with removing
excess starch buildup. It also keeps the cooking water at the optimum level by replacing
water evaporated during the cooking process. The AutoSkim function also saves energy
since there is no need to reheat a refilled cookpot. The cookpot is safeguarded against over
filling and boilover by a large overflow drain. “SD” following the model designation
indicates a stainless steel cookpot and door, and an enameled cabinet. “SC” following the
model designation indicates all stainless steel components.
8BC & 8C: These standalone cookers are essentially the same as the 8SMS, but without
the built-in rinse tank. 8BC models have an automatic basket lift and optional automatic
water filling and starch skimming. 8C models have no basket lifts and no automatic water
filling and starch skimming options. The cookpot in both is safeguarded against over filling
and boilover by a large overflow drain. “SD” following the model designation indicates a
stainless steel cookpot and door, and an enameled cabinet. “SC” following the model
designation indicates all stainless steel componentes.

2.2 Caster/Leg Installation
Depending upon the specific configuration ordered, your unit might have been shipped without installed casters or legs. If casters or legs are installed, you may skip this section and proceed to Section 2.3, Pre-Connection Preparations.
If your unit requires the installation of casters/legs, install them in accordance with the instructions included in your accessory package.
2.3 Pre-Connection Preparations
After the unit has been positioned in the area where it will be used, ensure the following have been
accomplished before connecting the unit to the electrical power source:
1. This equipment must be stabilized by installing restraining chains on units equipped with
casters or anchor straps on units equipped with legs. Follow the instructions shipped with
the casters/legs to properly install the chains or straps.
2. Level units equipped with legs by screwing the legs out approximately 1 inch, then adjusting
them so that the unit is level.
For units equipped with casters, there are no built-in leveling devices. The floor where the
unit is to be installed must be level.
3. Install the basket lift arm (on units so equipped) on the lift rod (located at the top rear of the
cabinet) so that the basket lift roller guides the lift arm.
NOTE: Some adjustment of the roller may be necessary for free movement of the basket lift
arm.
4. Connect the water hose to the fitting at the rear of the unit.
DANGER
The maximum allowable incoming water pressure for all units is 80 PSI (5.6 kg/cm2)
(551.6 kPa).
The maximum allowable incoming water temperature for all units is 180ºF (82ºC).
NOTE: Either hot or cold water may be connected to the unit. However, connecting hot
water will minimize the time required to bring the unit to boil when filling with fresh water.
NOTE: In order for the water level sensors to work properly, a certain amount of mineral
content in necessary in the water. For that reason, purified, deionized, or highly filtered water should not be used.
5. Connect the desired drain plumbing to the drain valve.

number plate located on the inside of the equipment door. To determine the appropriate
wire size, refer to the POWER REQUIREMENTS chart at the bottom of this page.
1. If the unit is not equipped with an installed power cord, open the door and remove the contactor
box cover. Position the unit to gain access to the rear and remove the lower back panel.
2. Insert an appropriately rated power cord into the rear of the contactor box and make connections
in accordance with the applicable wiring diagram on the following page. Install a strain relief on
the power cord and replace the lower back panel and contactor box cover.
3. Attach a plug that complies with national and/or applicable local codes to the free end of the
electrical power cord and plug the unit into an appropriate outlet.
POWER REQUIREMENTS
Use copper wire ONLY, suitable for at least 170ºF (75ºC)
The Spaghetti Magic II Controller allows the operator to specify a specific cook time in minutes and
seconds, then initiate a cooking cycle. This controller is available in three different configurations.
The standard configuration has both automatic filling (Autofill) and automatic skimming (Autoskim)
features. Options include Autofill only, or neither Autofill or Autoskim. On units configured with
the Autoskim feature, the operator may activate or deactivate the feature as desired.
When in the BOIL mode, the heating element is energized at all times. It is used when actually
cooking pasta.
The SIMMER mode feature maintains the water temperature just below boiling, which conserves
energy and water. This feature is designed for rethermalizing previously cooked packaged products,
and for keeping the cooker in standby.
The SKIM feature, when selected, adds water for approximately 3 seconds once a minute. It causes the
water to overflow into the drain, carrying floating starch with it. (A buildup of starch reduces the effi-
3-1
ciency of the cooker and can cause erroneous temperature and water level sensing. NOTE: Do not use
deliming solution to clean these units. Use of deliming solution will damage all stainless steel parts.)
LOW WATER SENSING automatically de-energizes the heating element if the water in the cookpot drops too low. When the water level in the cookpot is below the low-water sensor, such as when
draining and cleaning the cookpot, the controller display will read LO.
NORMAL WATER LEVEL SENSING, on units configured with the Autofill feature, automatically
adds water during or after a cooking cycle if the water in the cookpot drops to a level lower than approximately 1¼ inch (32mm) below the overflow drain. With this automatic filling feature, the water
level does not have to be continuously monitored. The cookpot always has the correct amount of water.
3.2 Operating Instructions
Before turning the cooker on, ensure that:
• the unit is connected to the water supply.
• the water supply is turned on.
• the unit is plugged into an appropriate outlet.
• the electrical power supply is turned on.
CAUTION
If this is the first time the unit is being used after installation, refer to Section 3.4, Boiling
Out the Cookpot.
1. Turn the controller on by pressing the Power switch.
2. The unit will automatically enter the boil mode and the boil mode indicator will illuminate. If
you do not intend to immediately begin cooking, press the Simmer Mode switch. The simmer mode indicator will illuminate. To re-enter the boil mode, press the Boil Mode switch.
3. Enter the desired cooking time using the numeric keypad. The time entered appears in the LED
display.
4. When ready to initiate a cooking cycle, press the Start Timer
switch. The basket lift will
automatically lower the basket or portion cups into the cookpot and the LED display will begin
to count down. At the end of the cooking cycle, an alarm will sound briefly to alert you and the
basket lift will automatically raise the basket or portion cups out of the water.
The display will automatically return to the previously set cooking time. If the same time is desired for the next batch, simply press the Start Timer switch when ready, otherwise enter the
new cooking time before pressing the switch.
5. To initiate the automatic skimming (Autoskim) feature, press the Skim
switch.

CHAPTER 4: PREVENTIVE MAINTENANCE
4.1 Daily Preventive Maintenance
It is normal for a coating of starch to form on the elements, sensors, and temperature probes during
operation. If the coating is allowed to build-up, it will adversely affect the operation of the
equipment. The preventive maintenance routines below should be performed at least daily to keep
your equipment functioning at peak efficiency. The cookpot and rinse tank – especially the waterlevel sensors, temperature probe, and element – may require more frequent cleaning, depending
upon the product and volume. NOTE: Do not use deliming solution to clean these units. Use of
deliming solution will damage all stainless steel parts.
Inspect Equipment and Accessories for Damage
Look for loose or frayed wires and cords, leaks, foreign material in cookpot or inside cabinet,
and any other indications that the equipment and accessories are not ready for safe operation.
Clean Cabinet Inside and Out
Clean inside the cabinet with a dry, clean cloth. Wipe all accessible metal surfaces and
components to remove accumulations of oil, dust, or cooking residue.
Clean the outside of the cabinet with a clean cloth dampened with dishwashing detergent,
removing oil, dust, or cooking residue.
DANGER
Never attempt to clean this equipment during the cooking process or when the
cookpot is filled with hot water and/or food products.
Clean Water-Level Sensors, Temperature Probe, Element, Cookpot, and Rinse Tank
Turn the equipment off and drain the cookpot (and rinse tank, if so equipped).
Remove the probe cover and clean the water-level sensors and temperature probe using a
Scotchbrite™ or similar abrasive pad and a solution of detergent and water.
Using a Scotchbrite™ or similar abrasive pad and a solution of detergent and water, clean the inside
of the cookpot (and rinse tank, if so equipped). Pay particular attention to the heating element.
Rinse the cookpot (and rinse tank, if so equipped) thoroughly with clean water at least twice.
WARNING
Do not use deliming solution to clean these units. Use of deliming solution will
damage all stainless steel parts.
WARNING
When cleaning around the element, be careful not to bend or otherwise damage the
high-limit thermostat capillary tube.
4-1
4.2 SMS II Controller Simmer Mode Adjustment
NOTE: The SMS II Controller simmer temperature is adjustable from 185ºF to 215ºF.
1. With the unit in the simmer mode, place the tip of a good grade thermometer near the
temperature probe and determine the actual water temperature in degrees Fahrenheit. If the
temperature is within 5ºF of the desired simmer temperature, nothing more needs to be done. If
it is not within 5ºF of the desired temperature, perform Steps 2 through 5.
2. With the unit in the simmer mode, open the control panel by removing the screws in the upper
corners and tilting the panel out.
3. Remove the black rubber plug from the top of the controller housing.
4. Using a small, flat-tipped screwdriver, turn the adjusting screw to change the simmer setpoint.
¼ turn will change the setpoint about 10ºF. (You will have to experiment with the direction of
rotation to determine which way to turn to raise or lower the temperature.) Wait at least 5
minutes, then recheck actual water temperature. Repeat this step until the water temperature is
within 5ºF of desired temperature.
5. Replace the plug in the controller, close the control panel, and replace the screws removed in
Step 1.

CHAPTER 5: OPERATOR TROUBLESHOOTING
5.1 Introduction
This chapter provides an easy reference guide to the more common problems that may occur during
the operation of this equipment. The troubleshooting guides in this chapter are intended to help you
correct, or at least accurately diagnose, problems with the equipment. Although the chapter covers
the most common problems reported, you may very well encounter a problem not covered. In such
instances, the Frymaster Technical Service Department will make every effort to help you identify
and resolve the problem.
When troubleshooting a problem, always use a process of elimination starting with the simplest
solution and working through to the most complex. Never overlook the obvious. Anyone can forget
to plug a cord into a receptacle or open the valve on the water supply line. Don’t assume that you
are exempt from such occurrences. Most importantly, try to establish a clear idea of why a problem
has occurred. Part of your corrective action involves taking steps to ensure that it doesn’t happen
again. If a controller malfunctions because of a poor connection, check all other connections while
you’re at it. If a fuse continues to blow, find out why. Keep in mind that failure of a small
component may often be indicative of potential failure or incorrect functioning of a more important
component or system.
Some of the troubleshooting actions recommended in this chapter involve removing suspect
controllers and substituting controllers that are known to be good. Whenever this is indicated, refer
to Section 5.3. Refer to Section 5.4 for instructions on replacing fuses.
If you have doubts as to the proper action to take, do not hesitate to call the Frymaster Technical
Service Department or your local Frymaster Factory Authorized Service Center for assistance.
Before calling a servicer or the Frymaster HOTLINE (1-800-551-8633):
• Verify that electrical cords are plugged in and that circuit breakers are on.
• Verify that water supply valves are open and that drain valves are fully closed.
DANGER
Hot water can cause severe burns. Never attempt to move a cooker containing hot
water or to transfer hot water from one container to another.
DANGER
Use extreme care when performing electrical circuit tests. Live circuits will be
exposed.
WARNING
Inspection, testing, and repair of electrical components should be performed only by
qualified service personnel. The equipment should be unplugged when servicing,
except when electrical tests are required.

ELECTRIC COOKERS 8SMS, 8BC AND 8C
CHAPTER 6: SERVICE PROCEDURES
6.1 Functional Description of Electric Cookers 8SMS, 8BC and 8C
Electric Cookers 8SMS, 8BC, and 8C contain an extruded stainless steel cookpot that holds 8.7
gallons (33 liters) of water. The water in the cookpot is heated by an 8-kilowatt element at the
bottom of the pot. The solid-state SMS II Spaghetti Magic controller controls electrical power to the
element. The 8SMS also has an 8.7 gallon (33 liter) rinse tank.
On units without the Autofill (automatic filling) option, when the controller is turned on by pressing
the Power switch, logic circuits in the controller check for water in the cookpot by looking for a
grounded low-water level sensor. (The sensor is grounded by contact with the water in the cookpot.)
If the sensor is grounded, the controller automatically enters the BOIL mode, supplying continuous
power to the element. If the operator selects the SIMMER mode, logic circuits in the controller
monitor the temperature of the water and cycle power to the element on and off to maintain the
temperature at the simmer mode setpoint. (See Section 4.2 in Chapter 4 for instructions for adjusting
the simmer mode setpoint.) The cooker also has a high-limit safety. If the water in the cookpot falls
below the low-water level sensor but the sensor remains grounded for whatever reason, the highlimit switch will open, cutting off power to the element, when the element temperature reaches
400 ±15ºF.
On units equipped with the Autofill option, a logic circuit in the controller automatically opens a
solenoid valve on the water supply line if the upper water level sensor is not grounded by contact
with the water in the cookpot. When the Power switch is pressed, if the water level is below the
upper water level sensor, water is automatically added to the cookpot. When sufficient water has
been added to cover the heating element, the unit automatically enters the BOIL mode and remains
there unless the operator presses the SIMMER mode switch or turns the unit off. When the water
level in the cookpot contacts the upper water level sensor, the solenoid valve in the water supply line
closes.
On units equipped with the Autoskim (automatic skimming) option, when the Skim switch is
pressed, a logic circuit in the controller automatically opens the solenoid valve in the water supply
line for three seconds every minute until the option is turned off by again pressing the Skim switch.
The operator enters a specified cooking time by pressing the number pads on the controller. When
the Start switch is pressed, the controller begins to count down to zero. When the controller times
out, an alarm sounds briefly, then the timer reverts to the last time entered.
On units equipped with basket lifts (8SMS or 8BC), when the Start switch is pressed to start the
cooking cycle, logic circuits in the controller activate the basket lift motor, lowering the baskets into
the cookpot. As the motor drives the basket lift down, a roller-activated switch loses contact with
the bellcrank (cam) attached to the motor and power to the motor is cut. When the controller times
out, logic circuits reverse the switch positions so that the motor circuit is again completed and the
motor is restarted, raising the baskets from the cookpot. At the fully raised position, the roller switch
again makes contact with the cam, cutting power to the motor and stopping the lift in the up position.

6.4 Troubleshooting
6.4.1 How the Autofill System Works
The heart of the automatic filling (AutoFill) system is a normally closed solenoid valve that opens
when 24VAC is applied. When the controller is turned on, it checks to see if the upper water level
sensor is grounded by contact with water in the cookpot. If it is not, circuitry in the controller forms
a ground for the 24VAC supplied to the solenoid, allowing the valve to open. When the water level
in the cookpot reaches the upper water level sensor, the sensor is grounded, causing the controller to
break the solenoid ground, thus shutting off the inflow of water.
Starch or lime build-up on the upper water level sensor may keep the ground from forming, therefore
the sensor must be kept clean and its lead firmly connected. NOTE: Do not use deliming solution to
clean these units. Use of deliming solution will damage all stainless steel parts.
This unit will not operate with distilled water. Pure water is non-conductive, so the required ground
cannot be formed. If highly filtered or purified water is used, adding ⅛-cup of baking soda to the
water will usually provide sufficient mineral content for the ground to form.
NOTE: In units equipped with the AutoSkim feature, when the skim switch on the controller is
pressed, a logic circuit in the controller automatically interrupts the 24VAC ground for three seconds
every minute until the switch is again pressed. Therefore, failure of the AutoSkim feature will be
due to a malfunctioning controller and not the solenoid valve.
6.4.2 How the Water Heating System Works
To prevent energizing the heating elements when there is no water in the cookpot, these units are
equipped with a low-water level sensor that must be grounded by contact with the water in the
cookpot before the control circuitry will apply power to the elements.
Starch or lime build-up on the low-water level sensor may keep the ground from forming, therefore
always make sure the sensor is clean and its lead is firmly connected. NOTE: Do not use deliming
solution to clean these units. Use of deliming solution will damage all stainless steel parts.
The units will not operate with distilled water since pure water is non-conductive. In order for the
ground to form, there must be some mineral content in the water. If highly filtered or purified water
is used, add ⅛-cup of baking soda to the water each time the cookpot is emptied and refilled.
In addition to the low-water level sensor discussed above, the water heating system has five more parts:
the high-limit thermostat, the temperature probe, the contactor block, the element, and the controller.
The high-limit thermostat functions as a normally closed switch. If the water in the cookpot falls
below the low-water level sensor but the sensor remains grounded for whatever reason, the highlimit switch will open when the element temperature reaches 400ºF ±15 (204ºC ± 9), cutting off
power to the contactor coil and thus to the element.
The temperature probe is used only when the unit is in the simmer mode. When the operator
selects the simmer mode, logic circuits in the controller monitor the temperature of the water and
cycle power to the element on and off to maintain the temperature at the setpoint programmed into
the controller.
6-11
The contactor block is the terminal block to which the element leads are connected and where
actual contact is made between the leads and the line voltage. Built into the contactor block is a coil
(electronic switch) that closes when a ground for the 24VAC from the transformer is supplied by the
controller calling for heat. When it closes, contact is made between the incoming line voltage and
the element leads.
The element is a resistive heating device. That is, when voltage is applied to the element, the
element gets very hot due to its resistance to current flow through it. The heat generated is
transferred directly to the water in which the element is immersed.
The controller is the interface between the operator and the other components of the equipment. In
the water heating system, its function is to control the application of line voltage to the heating
element via the contactor coil.
Troubleshooting the water heating system consists of checking the above components for proper
operation, as detailed in the troubleshooting diagrams on the next page.
