This document describes the Pitco MGII Full and Split Tank Gas Fryers, designed for commercial use, particularly in McDonald's restaurants. The fryers are equipped with a computer controller for precise temperature management and cooking timers.

Function Description:

The Pitco MGII Full and Split Tank Gas Fryers are commercial deep fryers used for cooking food in oil or shortening. They feature multiple fry tanks, allowing for simultaneous cooking of different products or larger batches. The computer controller manages the fryer temperature and provides cooking timers, ensuring consistent product quality. The fryers are designed with an integrated filtration system (if equipped) that allows for the filtering and reuse of cooking oil, extending its life and reducing waste. Gas is used as the heating source, controlled by gas valves and a pilot system.

Usage Features:

Computer Controller: Controls fryer temperature and provides timers for cooking products. Operating instructions for the McDonald's Computer Controller are included separately.
Fry Tank: Holds oil/shortening at temperature for cooking.
Door: Provides access to the drain valve handle, tank drain outlet, high limit reset button, gas valve, pilot, burners, gas shut-off valve, and self-cleaning burner system (if equipped). For filter-equipped units, it also provides access to the filter pan, filter pump, and oil/shortening return handle.
Filter Pan Guide Rails: Guide the filter pan into place beneath the fryer.
Filter Pan (if equipped): Oil drains from the fry tank into the filter pan, where it is filtered through filter media before being pumped back to the fry tank.
Gas Connection: Quick disconnect connects the gas supply to the fryer battery.
Casters: Provide for height adjustment and mobility of the fryer system.
Data Plate: Located behind the door, provides important information including Model and Serial Number.
Basket Hanger: Used for draining baskets when removed from the fry tank.
Hood Seal Angle: Mates up to a matching angle on Universal ventilation hoods.
Splashback: A protective barrier at the rear of the fryer.
Drain Valve Handle (Blue): Controls the flow of oil/shortening from the fry tank to the filter pan.
Pilot: Ignites the main burners when the fry tank requires more heat.
Self-Cleaning Burner System (if equipped): Cleans the main burners when the fryer is turned on.
Burner(s): Heat the oil/shortening in the fry tank.
Gas Valve Knob: Controls the flow of gas to the pilot and burners. Turning it to OFF shuts off the gas supply.
Oil Return Handle (Red) (if equipped): Opens the return valve, starts the filter pump, and returns oil/shortening to the fry tank.
Manual Gas Shut-off Valve: Shuts off the supply of gas to the gas valve.
Filter Pump (if equipped): Pumps filtered oil from the filter pan back to the fry tank.
Filter Pump Reset Button (if equipped): Resets the pump motor thermal overload.
Filter Pump Circuit Breaker (if equipped): Interrupts electricity to the filter pump in case of an over-current condition.
Filter Pump Pick-up Connection (if equipped): Where the filter pan engages into the filter pump suction piping.
High Limit Reset Button: If the high limit trips, it can be reset after the oil cools.
Drain Line Downspout (3") (if equipped): Discharges draining oil into the filter pan. Can be swiveled up to permit draining oil for discard.
Filling the Fryer Tank: Can be filled with liquid shortening or solid shortening. When using solid shortening, it must be melted slowly to prevent damage to the appliance. Water can be used for initial adjustments, but the level must not go below the MIN LEVEL mark.
Appliance Start-up: Ensure the drain valve is closed and the tank is filled with oil/shortening. Open gas supply valves, turn the gas valve knob to ON, and press the "ON" button on the controller.
Appliance Shutdown: Two modes: STANDBY and COMPLETE. STANDBY mode removes the ability of the appliance's main burners to operate. COMPLETE shutdown turns off the gas supply and cleans the appliance.

Maintenance Features:

Daily Preventative Maintenance:
- Filtering with a Filter Drawer: Slide out the filter pan, remove filtered residue, and check the filter media for clogging or tears. Replace if necessary. Clean the pickup tube screen. Remove baskets and use a clean-out rod and crumb scoop to remove excess crumbs from the tank bottom.
- Draining and Cleaning: Slowly open the blue drain valve handle to drain oil. Use a cleaning brush to clean the tank sides. Pull the red return valve handle to start the pump and return oil, rinsing crumbs down the drain. Press the "ON" button for a 5-minute polish timer. Close the drain valve handle once the tank is clean and oil has returned. Add oil if necessary to the "OIL LEVEL" line.
- Replacing Filter Media: Slide out the filter pan, lift out the paper retaining frame, and remove the old filter paper/pad. Place a new filter paper/pad and paper support screen, then reassemble.
Weekly Preventative Maintenance:
- Draining the Tank: The drain filter line is used when draining the fryers. The drain valve is opened, and the drainspout is rotated up to drain oil into a container.
- Cleaning the Fryer Tank: Turn off the fryer. Read the operation section for cleaning instructions. Scrub the tank, basket hanger, baskets, and temperature probe using a Scotchbrite™ or other abrasive pad with a commercial-grade cleaner. Rinse thoroughly with cool water.
- Cleaning the Cabinet: The inside of the cabinet should be cleaned with a clean dry cloth to remove oil, dust, dirt, and cooking debris. The outside of the cabinet should be cleaned with a wetted cloth and mild detergent.
Monthly and Quarterly Preventative Maintenance: Focuses on preventing food debris and oil/shortening buildup.
Annual/Periodic Preventative Maintenance and Inspection: This should ONLY be performed by a qualified service technician at least once a year.
- Temperature Probe & High Limit Probe: Verify good working condition, check for damage, tight fasteners, leak-free compression fittings, and tight electrical connections.
- Controller: Verify good mechanical condition, proper light/display/switch operation, overlay for damage, tight electrical connections, and correct cooking temperatures.
- Control Box & Electrical Components: Verify good condition of all components, tight wires, leak-free enclosures, safe covers/panels, and good power cord condition.
- Tank: Verify good condition, check for grease buildup, corrosion, and leaks.
- Drain System & Filter System (if equipped): Verify good drain valve condition, leak-free seal area, leak-free and kink-free drain/return lines, and secure clamps/connections.
Ventilation Hood: Proper operation is critical for appliance function and personnel safety. Regular inspection in accordance with ANSI/NFPA 96 and local codes is required.
