2 General
Read the instructions in this manual thoroughly before attempting to operate this equipment. This manual covers all configurations of Pitco SSHLV gas models. The fryers in this model family have most parts in common, and when discussed as a group, will be referred to as SSHLV fryers.
The SSHLV fryers feature a low oil volume frying vat, optional automatic oil top off and optional automated filtration unit. The Solstice design features a large round drain, which ensures that fries and other debris will be washed into the filter pan. The SSHLV fryers are controlled with an I12 + Controller. Fryers in this series come in full- or split-vat arrangements, and can be purchased in batteries of up to five fryers.

3 Theory of Operation
SSHLV Series gas fryers utilize a welded, stainless steel fryvat that is directly heated with high efficiency, atmospheric burner tubes. The atmospheric burner tubes eliminate the maintenance heavy and inefficient (over time due to clogging) blowers used in other fryers. Heat tubes provide as much as 80% more surface area for heat transfer than open vat fryers (tubeless), providing faster recovery without scorching the oil. Each tube, four total, is fitted with proprietary, incoloy baffles that are heated by air/gas jet emitted from our patented burners. The baffles transfer heat to the fryvat by means of infrared radiation and conduction plus convection flow from the air/gas jet. The tubular heat also allows for a “cold zone” below the tubes where cooking debris will settle at t temperature much lower than the cooking temperate. The lower temperature prevents the debris from carbonizing and oxidizing the cooking oil prematurely as typically found in non-tube style fryvats. In full-vat units, gas flow to the burners is regulated by one electromechanical gas valve. In split-vat units, each burner bank has its own valve to independently control each vat. All fryers in this series are equipped with 24 V AC gas valve systems, and all are configured with matchless ignition.
3.1 The Matchless Ignition System
An ignition module, mounted behind the gas valve, is connected to an ignitor/pilot assembly between the burners. The ignition module performs three important functions: provides an ignition spark, supplies voltage to the gas valve, and proofs the pilot flame. The module employs a four second time delay circuit (after flame sense) and a signal that activates the gas valve. Two types are currently used: A closed-box design is used in most fryers, but in some fryers built for export, the module is packaged differently. A single “one-spark” module is used on current production full-vat fryers. All dual-vat fryers use two single “one-spark” modules. The ignitor/pilot assembly consists of an igniter, a pilot tube/hood, and a flame sensor.
L22-392 R1 11
3.2 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
L22-392 R1 12
Figure 2 - Auto-Filtration Board (AFB)
L22-392 R1 13
NOTE
When the controller is on, the pilot should always remain lit.
3.3 Thermostats
SSHLV Series gas fryers have temperature probes located above and between the third and fourth heat tube of each fryvat (split vat fryers have two probes, one in each vat). SSHLV 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 burner firing when the resistance exceeds or falls below programmed temperatures (setpoints). SSHLV Series gas 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 high­limit 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).
3.4 Fryer Sequence Operation
The SSHLV 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.
3.5 Heating System
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.
• With the roll out switch and hi-limit in the closed position, the ignition module receives 24VAC
at terminal 6 (24 VAC).
• The ignition module:
• Sends 24 VAC from terminal 3(PV) to the PV terminal on the gas valve.
• Sends the igniter 15kv to spark.
• Senses the flame once the pilot has lit and it sends 24 VAC at terminal 1(MV) and puts 24 VAC
at the Heat Demand (HD) relay COM contact on the relay board. The HD relay on the relay board interrupts the 24 VAC supply to the gas valve until the controller calls for heat.
• The controller calls for heat:
• The HD indicator on the relay board is illuminated.
L22-392 R1 14

Inspect the filter pan prior to pulling the BLUE DRAIN VALVE HANDLE to insure it is empty. If the filter
NOTE
Circuit Breaker should remain in the “ON” position at all times.
• The HD relay is energized, closing the circuit sending 24 VAC to the MV terminal on the gas
valve.
• The computer is supplied with a 24 VAC heat feedback (HFB) signal.
3.6 Safety System
When the roll out switch or hi-limit trips, it interrupts the 24 VAC supply to the ignition module.
• When the controller calls for heat, it does not receive a 24 VAC HFB. With approximately 90 seconds of HFB loss, the controller indicates an ignition failure or heat failure.
• After the roll out switch hi-limit is reset, turn the controller off and then back on for the unit to heat.
3.7 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.
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 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.
Pulling the BROWN waste oil valve will: (If equipped):
WARNING
• 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.
L22-392 R1 15
3.8 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.
3.9 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 in a reservoir (or weir) at the front, top of the fry tank as pictured above:
• The probe reservoir must be free of debris & food particles to work properly.
• 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.
• 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 3­1/2 minutes or less.
L22-392 R1 16
• 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.
3.10 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 below) to drain the fry vat and return oil to fry vat after filtering.
Drain Valve Actuator (top) with Drain Valve (below) 1 Linear Actuator 1
• 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 instructions in this manual, Section 6)
• 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 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 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.

1. Display of “Blocked Drain- retry”. The drain is not closing and the controller is not receiving the signal that shows that the drain has been closed.
remove any food debris or foreign object from drain. Use of any other tool can damage your drain valve and will void the warranty.
2. Once you cleared the drain press “YES” button (6) key. If drain closes and the controller receives the correct signal, check the drain again to insure the cleaning tool has been removed. Your fryer should go back into normal mode. If not, your controller will scroll “block drain”. You only have 3 times to try and unblock drain before controller goes into lock out.
3.If after three tries, the drain is still blocked the fryer will no longer operate. If you have a multi fryer system, the other fryers shouldn’t be affected by this error. Contact Pitco Service or Authorized Service Person for assistance. There is NO reset from front controller panel.
4. If at any time you push “N” (0) key another scrolling message “FRYER WILL BECOME INOPERABLE”, “CONFIRM SHUT DOWN” message.
5. If you press the “N” (0) key then the message will revert to the display “Blocked Drain” as in number 1. If you press the “Y” (6) key message will display “Call Service – ERR” the fryer will no longer operate. If a multi fryer system the other fryers shouldn’t be effected by this error.
POWER. If the unit is unplugged and plugged in again, you WILL damage your drain valve and void the warranty.
