  • Page 3 Models designated MH52 do not have built-in filtration systems. Models designated BIH52 are equipped with FootPrint III built-in filtration systems. H52 Series fryers feature deep cold-zones and easy to clean, open frypots. The fryers are controlled by multi-product cooking computers or optional thermostat controllers. Fryers in this series come in full or split-pot arrangements, and can be purchased as single units or grouped in batteries of up to five fryers.
  • Page 4 Computer Information This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules. While this device is a verified Class A device, it has been shown to meet the Class B limits.
  • Page 5 McDonald’s store personnel perform routine maintenance. For non-routine maintenance or repairs, or for service information, contact your local Frymaster Authorized Service Center (FASC). Service information may also be obtained by calling the Frymaster Technical Services Department (1-800- 24FRYER). The following information will be needed in order to assist you efficiently:...
  • Page 6 (450 mm) should be maintained between the flue outlet and the lower edge of the grease filter.” Frymaster recommends that the minimum distance be 24 in. (600 mm) from the flue outlet to the bottom edge of the filter when the appliance consumes more than 120,000 BTU per hour.
  • Page 7 Frymaster computers have been tested and found to comply with the limits for a Class A digital de- vice, pursuant to Part 15 of the FCC rules. While these devices are verified as Class A devices, they have been shown to meet the Class B limits.
  • Page 8 Verify that the fryer is at the proper height in the exhaust hood. Frymaster recommends that the minimum distance from the flue outlet to the bot- tom edge of the hood be 24 in. (600 mm) when the appliance consumes more than 120,000 BTU per hour.
  • Page 9 5. Refer to the data plate on the inside of the fryer door to determine if the fryer burner is config- ured for the proper type of gas before connecting the fryer quick-disconnect device or piping from the gas supply line.

  • Page 10: Connection To Gas Line

    Connection to Gas Line The H52 Series has received the CE mark for the countries and gas categories indicated in the accompanying table. NOTE: The nominal heat input (Qn) is 21kW except for AT, DE, LU, and for category 3B/P under 50 mbar, which is 23kW.
  • Page 11 DO NOT apply compound to the first two threads. This will ensure that the burner orifices and control valve do not become clogged. 2. Open the gas supply to the fryer and check all piping, fittings, and gas connections for leaks. A soap solution should be used for this purpose.

  • Page 12: Converting To Another Gas Type

    Converting to Another Gas Type Your fryer is configured at the factory for either natural gas or propane (LP) gas. If you desire to switch from one type of gas to another, a gas conversion kit must be installed by a Factory Authorized Service Center technician.
  • Page 13 H52 Series Fryers manufactured for Non-CE countries use different burners for each type gas. The burners in fryers built for Propane gas have a special gray-colored coating on the burner tiles to en- able them to withstand the higher caloric value of the Propane gas. Burners designed for use in Pro- pane units may be used in natural gas applications, but not vice versa.
  • Page 14 Do not add vegetable oil to the fryer between the time the computer is turned on and the time it reaches programmed cooking temperature. Doing so is likely to cause RECOVERY LOCKOUT (REC LOCK).
  • Page 15 Introduction To The M-100B™ Cooking Computer The M-100B cooking computer, illustrated below, automatically maintains fryer temperature to cook products according to preprogrammed cooking specifications. The computer also acts as a cooking process timer, displaying the remaining cooking time for each product and alerting the operator by sound and display message to shake or pull the product at the correct time.
  • Page 16 (Polishing refers to circulating the vegetable oil through the filtration system for a specified time.) The fryer has two built-in high-limit protection features. If the temperature in the frypot reaches approximately 410°F (210°C), the computer opens the heat relay circuit, turning the burners off. If the temperature in the frypot reaches 450°F (232°C), a mechanical high-limit shuts off electrical...
  • Page 17 The cooking cycle cannot be started until the cooking oil is within ±15°F (8°C) of the programmed setpoint. When the frypot temperature is within ±15°F (8°C) of the programmed setpoint, the product name will be displayed continuously, indicating that the fryer is ready to cook the displayed product.

  • Page 28 How to Use the Filter Countdown Timer NOTE: This feature starts a five-minute countdown timer to time the polishing of vegetable oil during the filtering process. Polishing refers to circulating the vegetable oil through the filtration system for a specified time. This feature does not have any direct control over the filtration process; it is only a timer.
  • Page 29 The analog controller, illustrated on the following page, is used to adjust and maintain vegetable oil at the temperature indicated by the thermostat knob. The fryer has two built-in high-limit protection features. If the temperature in the frypot reaches approximately 410°F (210°C), the computer opens the heat relay circuit, turning the elements off.

When the vegetable oil temperature reaches the thermostat knob setpoint, the elements will cycle OFF and the heating mode light will go off, indicating that the fryer is ready for the cooking process to begin. Analog Controller High-Limit Check Tools needed: Maple Paddle, Fry Vat Probe.
  • Page 32 NOTE: You must agitate the vegetable oil with a maple paddle during the entire high-limit control- check procedure. If after completing both high-limit tests you find only the second high-limit operates properly, the vat can be used if it is absolutely necessary, but with extreme care. The controller must be replaced immediately after this period of necessity.
  • Page 33 If you intend to reuse the oil, Frymaster recommends that a Frymaster filter cone holder and filter cone be used when a filter machine is not available. Frymaster filter cone holder, be sure that the cone holder rests securely on the metal container.
  • Page 34 5. Close the drain valve securely and fill the frypot with clean cooking oil to the bottom OIL- LEVEL line. Operating the Built-In Filtration System The FootPrint III (FP III) filtration system allows the cooking oil in one frypot to be safely and effi- ciently filtered while the other frypots in a battery remain in operation.
  • Page 35 4. Verify that the filter screen is flat in the bottom of the pan. Lay a sheet of filter paper over the top of the pan, overlapping on all sides (or place an optional filter pad in the bottom of the pan.) NOTE: If using the optional filter pad, ensure that the rough-textured side of the pad is up.
  • Page 36 Never drain more than one fryer at a time—the filter pan may overflow. When unclogging a valve, DO NOT insert anything into the drain from the front of the fryer. Hot oil will rush out, creating an extreme hazard.
  • Page 37 2. After all oil has drained from the pot, rotate the Rear Flush handle to the ON position to activate the pump. There may be a slight delay before the pump activates. 3. As the filtering progresses, the computer will display the time remaining. When the filtering time has elapsed, FILTER will flash in the display.
  • Page 38 Cleaner HSC. Place the baskets into the frypot and bring the solution to a simmer at 195° F (90.5° C) for 1 hour. Turn OFF the fryer, drain the solution and wipe the frypot clean and dry. NOTE: Do not drain water into the filter pan. Water will damage the filter pump enough to re- quire replacement.
  • Page 39 c. Rinse the filter pan thoroughly to remove the detergent. Wipe dry with a clean, dry cloth or paper towels. d. To clean the filter base assembly, use a sponge or cloth soaked with a water and grease- cutting solution. Be careful not to get water on the pump/motor assembly. e.
