The LOV™ Systems

Auto Top Off

The core of the system is the automatic top-off board, which senses when the oil level is low and fills the pot to the top line.

The oil level is monitored by an RTD (Resistance Temperature Detector) sensor in the frypot at the upper oil level. The oil is moved to the pot from a reservoir, called a JIB (Jug In Box), to the frypot with a pump.

A circuit board, the ATO (Automatic Top Off), is located inside a box behind the JIB. It monitors the oil-level RTD and activates the pump when it senses an oil temperature drop of 60°F (33°C) below set- point, indicating the oil has moved away from the sensor. The ATO sends a signal to the MIB (Manual Interface Board), which then sends a signal to the AIF to open the actuator on the return valve of the frypot to be topped off.

Once the actuator has opened the return valve, oil is pumped into the vat for a specified amount of time (approximately 60 seconds). When the ATO RTD detects a temperature within 55°F (30°C) of set- point, it is satisfied and the actuator closes the valve.

Top off will continue on the next vat if needed. The system is not suited to filling the frypot when it is empty and there are safeguards to prevent it from activating when the fryer is cold and the oil is rest- ing at the lower position.

The system is not active until the oil in the frypot reaches setpoint. That temperature is monitored by the temperature probe. The activation of the system is handled by the fryer’s computer, the M3000. The automatic top off system is also inactive during filter dispose cycles.

The system works the same in McDonald’s gas and electric LOV™ systems.

The level of the reservoir, or JIB, is monitored by the ATO and the M3000 computer. If a low oil condition is not rectified with two top off attempts or within 6 minutes, the low JIB light is illuminated on the front of the fryer. It will stay illuminated until the JIB is replaced and the orange button has been pressed and held to reset the light (see page 34).

The ATO board positioned underneath the LON gateway controls the top off of the fry pots.

The pump that moves oil from the reser- voir to the frypots is visible above.

M3000 specifications

The Frymaster M3000 is a state-of-the-art frying solution that has gained popularity in commercial kitchens due to its impressive capabilities and advanced technologies. This fryer is designed to provide consistent, high-quality results while maintaining efficiency, making it an ideal choice for restaurants, fast food outlets, and foodservice operations.

One of the significant features of the Frymaster M3000 is its oil management system. This advanced technology helps to extend the life of the cooking oil, reducing overall costs and improving food quality. The system monitors the oil's condition and alerts users when it is time to filter or change the oil, ensuring that the frying process remains uncompromised and that food is cooked to perfection.

The M3000 is equipped with a precise temperature control feature that allows users to set and maintain accurate cooking temperatures. This is critical in achieving optimal frying results, as various food items require different temperature settings for the best flavor and texture. The fryer also boasts rapid recovery times, meaning that it can quickly return to the desired temperature even after adding food, which is essential during busy peak times.

Additionally, the Frymaster M3000 incorporates a unique fry pot design that promotes even heat distribution throughout the cooking oil. This feature helps in reducing hot and cold spots, allowing for a more consistent frying experience. The design also facilitates easy cleaning, as the fry pot can be easily removed and maintained, thus improving overall kitchen hygiene.

Another notable characteristic of the M3000 is its user-friendly digital control interface. This intuitive system allows operators to program cooking times and temperatures easily, streamlining the frying process. With built-in diagnostic features, the fryer can notify users of potential issues, aiding in preventive maintenance and reducing downtime.

The Frymaster M3000 is also designed with safety in mind. Features such as auto shut-off, temperature limiters, and secure oil containment systems reduce the risk of accidents in busy kitchen environments. This attention to safety reassures operators that they are using a reliable piece of machinery.

In summary, the Frymaster M3000 is an exceptional commercial fryer that combines advanced technology, user-friendly controls, and a focus on safety and efficiency. Its oil management system, precision temperature control, rapid recovery, and ease of maintenance make it a preferred choice for foodservice professionals seeking reliable and high-quality frying solutions. With the M3000, consistent performance and culinary excellence are always within reach.
