1.2 Theory of Operation

The cabinet operates on 208-250VAC 50 or 60 cycle single-phase power. The main switch activates a relay, which supplies line voltage to two distribution boards, three cooling fans and a power supply. The power supply provides 5VDC to the master control board and the distribution boards.

A ribbon cable connects the master control board to both distribution boards. Ribbon cables also connect the distribution boards to the displays. The resistance of RTD’s, attached to the heater plates, is monitored by the distribution boards. The board switches power through solid-state relays to the heater plates when the resistance, which is used as an indicator of temperature, falls out of the range for the product held in the cabinet.

The switch, relay, master control, master control board, LON board, LON filter, cooling fans and power supply are mounted under the top of the unit. The cabinet is programmed using the key pad on the front bezel.

This built-in filtration system continuously circulates and filters the oil, removing impurities and extending its usability, resulting in cost savings on oil purchases and reduced waste. The fryer also features a simple, intuitive user interface that provides operators with real-time data on oil quality and temperature, allowing for precise control over the frying process.

Another significant benefit of the UHC-HD is its durability and ease of maintenance. Constructed from high-quality materials, this fryer is designed to withstand the rigors of daily use. The fryer’s design allows for easy access to components, making routine cleaning and maintenance straightforward. This focus on durability not only enhances the fryer’s lifespan but also helps ensure consistent cooking performance.

The Frymaster UHC-HD also incorporates advanced safety features. The enhanced safety mechanisms include temperature limiters and automatic shut-off functionalities, which minimize the risk of overheating and accidents in the kitchen. This attention to safety is critical in fast-paced cooking environments where operators must prioritize efficiency without compromising on safety.

In conclusion, the Frymaster UHC-HD stands out as a premier choice for anyone looking to elevate their frying capabilities.
