3 TheoryofOperation

SELV Series electric fryers utilize a welded, stainless steel fryvat that is directly heated with high
efficiency, ribbon style heating elements. Ribbon style elements offer a lower watt density per square
inch and are gentler on the oil. The elements rotate upward for easy cleaning. In full-vat units, heat
demand to the elements is regulated by one electromechanical contactor. In split-vat units, each
element bank has its own contactor to independently control each vat. All fryers in this series are
equipped with 24 V AC control circuits, and the elements can be configured to accommodate a wide
range of electrical supply.

L22-393 R0 Page 12

3.1 The Heating System

A hi-limit device located in the fry vat provides an additional level of operator safety. If the high limit is
satisfied that the fryer is operating within design parameters, a “side on” contactor will close and stay
closed so long as the cooking oil temperature stays below a specified limit. This safety circuit minimizes
the operations of the “side on” contactor to insure it can open in the unlikely event of a run away
condition. The “side on” contactor is wired in parallel with the “heat demand” contactor to deliver main
power to the heating elements. The heat demand contactor is controlled via the I12+ control board
which responds to input from a thermistor located in the fryvat. When the thermistor transmits a
temperature reading below the desired cook temperature, the I12+ closes the heat demand contactor
completing the circuit to supply electrical energy to the hating elements until the oil temperature
matches the desired cooking temperature. Should the high limit trip, it cannot be reset until the oil
temperature falls below the hi-limit threshold, so the unit needs to cool. The cause of the hi-limit tripping
should be investigated and corrected prior to putting the fryer back into service.

The unit is connected to line voltage:

If Fuse F1 on the relay board is good:

 The A.C. indicator is illuminated.

 The controller is supplied with 24 VAC.

 With the drain valve handle closed, the proximity switch supplies 24 VAC to the drain valve interlock

(DVI) input at the controller.

 24 VAC is at the Side On (SO) relay COM contact.

The controller is turned ON:

 The SO indicator on the relay board is illuminated.

 The SO relay is energized, closing the circuit.

 The safety (SO) contactor energizes if the hi-limit is not tripped.

3.2 Hi-Limit System

If the hi-limit trips:

The SO and HD contactors lose 24 VAC supply and the HFB loses 24 VAC.

The computer displays “HEATING”.

The HD lamp is illuminated on the Back-up T-stat and the HFB lamp is not illuminated.

After the hi-limit resets (unit cools to 375°F ±20°F (191°C ±20°C)), turn the controller off and then
back on for the unit to heat.

L22-393 R0 Page 13

3.3 Auto Filtration Boards

All fryers in this series have an Auto-Filtration Board (AFB) located in the component box behind the
control bezel. The AFB provides a “bus” between the controller and the fryer's individual components
without requiring additional wiring by using a communication protocol over a twisted pair, and allows the
controller to execute commands from one central point. The heat control circuit is show below in Figure

1. This is the bottom left corner of the AFB. For a split vat, this is duplicated on the bottom right hand
corner.

Figure 1 - Bottom left corner of Auto Filtration Board

L22-393 R0 Page 14

Figure 2 - Auto-Filtration Board (AFB)

L22-393 R0 Page 15

3.4 Thermostats

SELV Series electric fryers have temperature probes located between the heating elements in the
center, bottom of the vat. In a full vat, the temperature probe is on the right bank of elements. There is
always one in each vat, full or split. SELV fryers, like all Solstice series fryers, use a thermistor style
temperature probe. In this type of thermostat, the probe resistance varies directly with the temperature.
That is, as the temperature rises, so does resistance. Circuitry in the controller monitors the probe
resistance and controls heat demand contactor when the resistance exceeds or falls below
programmed temperatures (setpoints). SELV Series electric fryers are also equipped with a high-limit
thermostat. In the event that the fryer fails to properly control the oil temperature, the high-limit
thermostat prevents the fryer from overheating to the flash point. The high-limit thermostat acts as a
normally closed power switch that opens when exposed to temperatures above 425°F to 450°F (218°C
to 232°C).

3.5 Fryer Sequence Operation

The SELV fryer components function in specific order of operation. Knowing and understanding the
sequence of fryer and components operation enables you to diagnose equipment failure more
accurately.

3.6 Filter System (Manual Filtration Only)

Pulling the BLUE drain valve handle will:

Open the drain at the bottom of the fry vat

Open the “Drain Valve Interlock” (DVI) magnetic switch disabling the heating system during
filtration.

!WARNING!

Inspect the filter pan prior to pulling the BLUE DRAIN VALVE HANDLE to insure it is empty. If the filter
pan has visible oil, opening the valve will result in hot oil overflow onto the floor resulting in slipping
hazards, fall related injuries, serious burns or death.

Push handle in to close Drain and enable DVI.

Pulling the RED (If Equipped) return valve handle:

 Opens the return valve to that vat.

 Closes the pump proximity switch causing the “pump run” relay to be energized.

 The pump motor begins to run.

Closing the return valve handle de-energizes the relay and the pump motor stops running and the
return valve closes.

The pump system is equipped with a circuit breaker which de-energizes the system and the heat
tape (If equipped) in the event of over current. The circuit breaker must be in the “ON” position for
the pump and heat tape to operate.

Circuit Breaker should remain in the “ON” position at all times.

NOTE

Pulling the BROWN waste oil valve will: (If equipped):

Divert oil flow from the pump to the fry vat to user supplied waste oil plumbing through a Pitco
supplied three way valve.The return piping system may be provided with optional heat tape to
prevent solidification of solid shortening. The heat tape is low wattage and is on constantly to
maintain liquid shortening in the line.

L22-393 R0 Page 16

3.7 Basket Lift (Optional)

The basket lift is a self contained unit that requires a 120V, 208V, or 240V supply. With most fryer
configurations, the power is supplied from the entrance box at the back of the fryer, but some
configurations require power directly from a wall outlet.

When power is supplied to basket lift assembly, the baskets lift to the up position.

The baskets lower with a 24 VDC output from the controller.

The basket lift control voltage is supplied from the controller

The basket lift operational voltage is supplied from the line voltage supply that powers the
transformer in the basket lift assembly.

3.8 Auto Top Off – ATO (Optional)

If equipped, the optional Auto Top Off (ATO) adds small doses of oil from the “Jug in Box” or JIB
when low oil conditions are detected. During frying, small amounts of oil are absorbed (called “drag
out”) by the food and removed from the fryer. These small amounts eventually lead to
replenishment with a “Top Off” event.

The fryer cannot be filled from empty with the Auto Top Off option.

The ATO uses the filter pump to move oil from the JIB to the fry vat when low oil conditions are
sensed. A linear actuator redirects the pump flow from the JIB during a Top Off event.

The ATO doesn’t not operate during a cook cycle to keep the oil hot during cooking. Adding room
temperature oil during cooking would negatively impact the cook cycle and product.

The ATO probe is located on the rear wall of the fry tank as pictured below:

The ATO probe plugs into the Auto Top Off relay board behind the front control bezel.

The following conditions must be met for the ATO event to occur:

The vat must be in idle condition, not cooking or melting, with display showing “Ready” or “Drop”.
This display typically shows when the vat is within 20°F of cooking set-point.

L22-393 R0 Page 17

When the cooking control shows Ready, the oil level probe will take time to detect the low level
condition. The lower the level the faster the response. The reverse is also true. Modestly low
levels take longer to resolve. (< 3/8” below probe). Levels ½” below probe should detect in 3-1/2
minutes or less.

Food debris, or oil caked onto probe may prevent ATO operation. Occasional probe cleaning when
vat is empty and cool is recommended.

Top off does not occur when the control is Off, Melting, Cooking, or Heating.

3.9 Automated Filtration (Optional)

If equipped with an Automated Filtration system, the filtration works like any other Solstice Fryer
except the manual handles (blue and red) are replaced with actuators (show above) to drain the fry
vat and return oil to fry vat after filtering.

The Automated Filtration system does not actuate “automatically”, user input is required.

The actuators for the drain valve and return valve can be manually operated through the I12
computer. (See Section this manual,9)

When a pre-determined threshold (typically a user programmed number of cooks) is reached, the
operator can be prompted to filter the cooking oil. Upon successful operator input, the system:

Begins an automated filtration process that first opens the drain valve and drains the oil into the
filter pan.

Shortly after the drain valve opens, the linear actuator opens the return valve and the filter pump
actuates. The filtering process operates for a pre-defined period of time (user programmable)

The drain valve closes and the pump continues to run, returning the freshly filtered oil to the fry vat.

When timer reaches zero all the oil has been pumped back to the fry vat, the pump turns off and the
return valve closes.

The operator is queried to insure the vat is full. If the operator responds “NO”, the filter pump turns
on for 20 seconds and the return valve is opened to pump any remaining oil from the filter pan.
When the operator responds “YES”, the fryer turns itself off and must be re-energized by the
operator pressing the “ON” key to restore power and begin frying.
