This will display the Duke Logo along with the firmware version number of the RFHU. Different types of information are found on the runtime screen. Details below. RUNTIME SCREEN After the RFHU has loaded the runtime screen will load. When the unit first boots each well will contain a preheating icon. This indicates the well is heating to temperature. When the recipe temperature is reached the preheat icon will clear and the well will be ready for use. In this instance a 3X4 RFHU has been detected. A "3X4" has a layout consisting of 3 rows by 4 columns containing up to 12 programmed recipes in total. 9 RFHU Operator's Manual RFHU OPERATING INSTRUCTIONS - Continued Each recipe is programmed with a "hold time". The hold time can be configured for any time between 1 minute to 540 minutes. Pressing on any well will start the timer. Three-day part menus are available to be selected on the runtime screen. When selected these will change the recipe display. For example, during Breakfast hours you may hold different recipes to lunch or dinner. Changing from "Menu 1" to "Menu 2" will change all non-running programmed recipes name to the new menu layout. When a well is started the color of the well will change to green, use this product first. When the second well of the same recipe is started the started well change to amber, use this next. When subsequent wells of the same recipe are started, they will also be amber. If a different well is started with a different recipe and there is no other well running with the recipe - then it will also have green background. When the well countdown timer expires, the timer shows a "X", the will turns red and an alarm will sound. Touching the well, cancels the alarm. To cancel an unexpired timer you must press and hold. If a well is currently running and the menu is changed the new recipe name will not take effect until the well has been stopped or expired and cleared. A Cook More time value can be programmed for each individual recipe. The "Cook More time" is used to indicate that the remaining hold time of the current recipe is low and they should start cooking/ preparing the recipe once more. A "+" symbol appears on the individual well with the cook more time indicator. For example: 10 RFHU Operator's Manual RFHU OPERATING INSTRUCTIONS - Continued PREHEATING When the RFHU first boots each well will contain a preheating icon.

USB Programming In some cases the connected RFHU unit may not be online and connected to the DCEP. If this is the case the RFHU recipe and programming settings can be modified on the actual unit UI or alternatively the RFHU Offline Configurator menu option can be used on the DCEP. This can be found under "Recipe" menu on the side menu of the DCEP. 22 RFHU Operator's Manual RFHU OPERATING INSTRUCTIONS - Continued For the user's Account an "offline recipe set" will always be available to the user. This information will be saved and be readily available if a USB file is required to be created. The RFHU Configurator is available for well programming. As the unit is not connected the RFHU configuration, for example 2x2, 2x4 will not be automatically detected. This can then be programmed in the same way as the online RFHU. For example: Instead a list of available configurations will be available for programming. These include: When finished select "DOWNLOAD PHU CONFIGURATION FILE" option. This will create a RFHU "RCP" file which contains both the recipe list and well mapping settings. This file can then be copied to the "root" directory of a USB flash drive. Plug this same USB drive into the USB port on an RFHU and if the configuration is correct both the recipe list and well programming will be uploaded on the unit itself. A confirmation message will appear on the RFHU display when a new recipe set has been successfully loaded. When a selected PHU configuration is selected the appropriate programming grid will appear. For example a 2x4 will appear as: 23 RFHU Operator's Manual CLEANING GUIDE Electrical shock hazard. Do not wash with water jet or hose. DO NOT USE CAUSTIC CLEANERS, ACIDS, AMMONIA PRODUCTS OR ABRASIVE CLEANERS OR ABRASIVE CLOTHS. THESE CAN DAMAGE THE STAINLESS STEEL AND PLASTIC SURFACES. Bottom and sides of warmer wells are very hot and cool slowly. DAILY CLEANING · Stainless Steel Surfaces To prevent discoloration or rust on stainless steel several important steps need to be taken. Stainless steel contains 70-80% iron which will rust. It also contains 12-30% chromium which forms an invisible passive film over the steel surface which acts as a shield against corrosion. As long as the protective layer is intact, the metal will not corrode. If the film is broken or contaminated, outside elements can begin to breakdown the steel and begin to form rust or discoloration. Proper cleaning of stainless steel requires soft cloths or plastic scouring pads. NEVER USE AN ACID BASED CLEANING SOLUTION! MANY FOOD PRODUCTS HAVE AN ACIDIC CONTENT WHICH CAN DETERIORATE THE FINISH. BE SURE TO CLEAN ALL FOOD PRODUCTS FROM ANY STAINLESS STEEL SURFACE. COMMON ITEMS INCLUDE, TOMATOES, PEPPERS AND OTHER VEGETABLES. THE POWER MUST BE TURNED OFF AND DISCONNECTED AT ALL TIMES WHEN PERFORMING MAINTENANCE OR REPAIR FUNCTIONS. Never use steel pads, wire brushes or scrapers. Cleaning solutions need to be alkaline based or non-chloride cleaners. Any cleaner containing chlorides will damage the protective film of the stainless steel. Chlorides are also commonly found in hard water, salts and household and industrial cleaners. If cleaners containing chlorides are used, be sure to rinse repeatedly and dry thoroughly upon completion. Routine cleaning of stainless steel can be done with soap and water. Extreme stains or grease should be cleaned with a non-abrasive cleaner and plastic scrub pad. It is always good to rub with the grain of the steel. There are also stainless steel cleaners available which can restore and preserve the finish of the steels protective layer. Early signs of stainless steel breakdown can consist of small pits and cracks. If this has begun, clean thoroughly and start to apply stainless steel cleaners in an attempt to restore the passivity of steel. NEVER USE A HIGH-PRESSURE WATER WASH FOR THIS CLEANING PROCEDURE AS WATER CAN DAMAGE ELECTRICAL COMPONENTS ELECTRICAL SHOCK HAZARD. DO NOT WASH WITH WATER JET OR HOSE. RECOMMENDED SUPPLIES Cleaning Towels Non-Scratch Scrub Pad KAYTM Degreaser KAY® SINK SANITIZER, KAYQUATTM Sanitizer, or compatible sanitizer 24 PROCEDURE CLEANING GUIDE - continued RFHU Operator's Manual 1. Turn unit off, unplug, and allow to cool for 30 minutes. 2. Remove all holding pans and heat sink covers. Wash, rinse, and sanitize at the 3 compartment sink. 3. Allow to air dry. 4. Spray a cleaning towel, or non-scratch scrub pad when necessary, with soapy solution or KAYTM Degreaser. Fully clean upper heat sink surfaces by hand, as well as lower heat sink surfaces Take care when reaching in the cabinet. Pan and lid guides present sheet metal edges which could be sharp. NOTE: Never spray cleaning solution directly onto the cabinet. 5. If daily cleaning is performed routinely, deeper, more aggressive, cleaning methods can be avoided. Over longer periods of time, fried food product can accumulate and bake on to the upper heat sink surfaces of the compartments. 6. Use a sanitizer-soaked towel and wipe out all compartments on the holding unit. Wipe top compartments first, and then lower compartments. IMPORTANT: Use clean, sanitizer-soaked towels (Important: towels must be wrung out so that they are damp and not dripping, dripping towels may harm the unit.) DAILY INSPECTION CHECKLIST: Make sure that: · Unit is free of any visible food soils. · Unit is free of grease or soils in holding compartment. · Exterior of unit is free of smudges or soil. · Holding pans are free of any food soil residue. · Pans are free of damage such as cracks. 25 RFHU Operator's Manual TEMPERATURE CHECK PROCEDURE 1. A digital temperature meter that has been calibrated must be used to get an accurate temperature reading. Use a thermocouple surface temperature probe to measure temperatures. 2. No pans should be in wells during the preheat and temperature check. Pre-heat the warmer for 30 minutes before taking any temperature readings. Do not take readings unless the cavity has been empty for 30 minutes. This will allow the temperature to stabilize and will prevent false readings. 3. The warmer cavity should be cleaned and empty before the temperature is checked. Avoid any air drafts that might flow through the cavity. 4. Temperature readings should be taken when standing on the front side of the unit with on/ off switch. Locate the surface temperature probe on the bottom of the first cavity. Position the probe half way back on the heat sink beneath the rail as shown. The top readings should be taken on either side of the rail half way back on the heat sink. Four wide units require 2 readings, left and right side. 5. All temperature controls exhibit a swing in temperature as the control cycles on and off while regulating to the set point. The correct calibration temperature is the average of several readings taken over a period of 20 minutes after the warmer has been pre-heated. The average temperature should be no greater than ± 10°F (± 6°C) from the set point. 6. The allowable range of well temperatures which can be programmed on the RFHU is 140°F-280°F (60°C-137.8°C). 7. If the calibration temperature is greater than +/- 10F (6C) from the set point, adjust the temperature offset as described under the Tools menu. The offset value should be set as the difference between the calibration temperature and the set point. 8. Repeat for all heat sinks.
