12.4.2002 Rev. 2.0 Functional description 5. These waves do not heat the air through which they pass. Instead the waves are absorbed by the outer surface of the product transported through the oven on the conveyor belt. Using this application food is placed on the conveyor and the unique properties of the infrared waves cause it to cook from the outside to the center in traditional fashion. Heat Zones The heat zones refer to individual areas of heat control within a cooking deck (chamber).

12.4.2002 Rev. 2.0 Operation instructions 4. Operation instructions 4.1 Before using the appliance Before you begin to cook with your new oven you must understand the differences between cooking in it and cooking in more conventional ovens. You will produce better results if you understand the technology and follow the “rules”. 4.1.1 Infrared Cooking Technology The technology of infrared cooking used in the CTX Gemini series ovens was first introduced by CTX in 1969.
12.4.2002 Rev. 2.0 Operation instructions Top Element Överelement Yläelementti 24° max. differential Max. 24° ero Bottom element Nedre element Alaelementti 4.1.3 Cooking Trials The purpose of conducting cooking trials is to determine the exact temperature settings and cooking time(s) needed to produce best results with your specific product(s). The fastest and easiest way to conduct these trials is to start with settings already established for product(s) similar to yours.
12.4.2002 Rev. 2.0 Operation instructions After evaluating the results, make the indicated time/temperature setting adjustments and allow about 15 minutes for the oven to stabilize at the new temperature settings. It may be necessary to run several tests before you obtain the exact results you want. Be sure to document each test in the “Product Test Record” below so you can ultimately produce a cooking chart for your specific items. Product 4.2 State Temp. Setting Top/Bott Cook Time (Min.

12.4.2002 Rev. 2.0 Operation instructions • 4.2.3 Cooking Temperatures Because infrared waves do not heat the air in the oven chamber the temperature settings and readings are surface temperatures of the infrared heat panels themselves. For this reason temperature settings will be higher than those for a conventional oven.

12.4.2002 Rev. 2.0 Operation instructions 4.2.4 Loading the Conveyor Achieving maximum production is dependent on proper utilization of the conveyor belt. Depending on size, pans can be placed on the conveyor belt in a variety of configurations to best use the space available. Figure below shows placement of various size round pans to achieve maximum production rates. Pans in other sizes or shapes will require different placement.

Reinstall filter and grill. BE SURE filter is dry before reinstalling. Electrical components are directly below the cooling fan. Cleaning the Oven Chamber The G-26 has a self-cleaning mode. The cleaning operation procedure is outlined below. Do not reach into hot oven. Severe burns could result.
12.4.2002 Rev. 2.0 Operation instructions Cleaning “Loose” Parts Commercial oven cleaners can be used to clean stainless steel “loose” parts. The following items must be removed from the oven to be cleaned manually in the pot sink. These procedures should be performed only when the on is OFF, cool to the touch and the conveyor is stopped. Crumb Trays: Clean daily. Lift the belt and remove the crumb trays from both entrance and exit end of each conveyor. Empty residue, wash, rinse and dry thoroughly.
12.4.2002 Rev. 2.0 Operation instructions Pivoting Heat Curtains: Clean as needed. Unhook the pivoting heat curtains from the rods above the entrance and exit ends of each conveyor. Wash, rinse and dry thoroughly. Re-install. Adjustable Heat Curtains: Clean as needed. Remove adjustable heat curtains from each end of oven. Wash, rinse and dry thoroughly. Re-install. Cleaning the Exterior Disconnect the oven’s power supply cord from its receptacle before you start to clean the oven.
12.4.2002 Rev. 2.0 Installation 5. Installation 5.1 Unpacking the oven The oven components should be moved as close as possible to final location before being assembled/stacked. The oven setting on its bottom, requires door openings wider than 679mm. Open carton and remove it from around oven, then remove the empty carton from the area. Directions for removing the wooden skid are on the following page.

Once the ovens are stacked and secured check to make sure the oven(s) are level. Adjust the legs if necessary as shown in the figure below.
12.4.2002 Rev. 2.0 Installation 5.2.3 Conveyor Belt and Temperature Display The conveyor belt is designed to travel in either direction using the conveyor Reversing Key Switch. The temperature display may be set for either °F or °C. Your Certified Installer will set both of these functions for you during the installation. If you require a change in the degrees display (Fahrenheit or Centigrade) in the future call your local Authorized Service Agency. 5.2.
12.4.2002 Rev. 2.0 Installation 5.2.5 Pivoting Heat Curtains The oven is shipped with adjustable heat curtains attached to the oven and pivoting heat curtains are also supplied with the oven. To use the pivoting heat curtains first remove adjustable heat curtains and then install the pivoting heat curtains by hanging them on the steel rod as shown in the figure below. 5.2.6 Exit Tray Next install the desired exit tray at the exit end of the conveyor.
12.4.2002 Rev. 2.0 Installation 5.3 Positioning the appliance Some very important considerations must be made when choosing the place where the oven is to operate. 1. 2. 3. 5.4 This oven is conveyorized and operates continuously. It should be placed so it fits into the “flow” of the operation. Drafts entering the oven chambers can cause inconsistent cooking results.
12.4.2002 Rev. 2.0 Installation Overcurrent protector must be in OFF position and oven disconnected from power supply when removing or servicing the appliance. Professional should disconnect the oven from its power supply. 5.5 Programming the G-26 MenuSelect Control Oven The oven controller controls all functions of the oven. To operate the oven the controllers must be programmed. The following pages contain a step by step “hands on” programming exercise.
12.4.2002 Rev. 2.0 Installation It is recommended that the temperatures of the top and bottom zones be set WITHIN 24°C OF EACH OTHER. Greater temperature differences may result in the hotter zone heating the cooler zone. This may cause inconsestent cooking results. See the figure below.. Top Element Överelement Yläelementti 24° max. differential Max. 24° ero Bottom element Nedre element Alaelementti 5. 6. Set cook time Press key. The current cook time appears in the display (minutes : seconds).
12.4.2002 Rev. 2.0 Troubleshooting 6. Troubleshooting Error codes are used in troubleshooting to indicate a possible problem and/or corrective action. These codes are shown in the MenuSelect display and are explained in the following chart. An authorized service representative must be contacted for any failures that cannot be remedied by reprogramming. Do not remove access panel at rear of control compartment. High voltage exists inside compartment which can cause serious injury or danger to life.
12.4.2002 Rev. 2.0 Troubleshooting Oven is dark Conveyor runs full speed or uncontrollably No Did oven circuit breaker trip? Located next to control panel. Plug in No Is power cord oven. plugged in? Check your cooktime setting. It may be set too fast. Yes Check main circuit breaker If cooktime is correct turn ON/OFF switch OFF and then ON. If belt speed is still incorrect call your local authorized service agent. If cooktime setting is at 30:00 minutes belt may appear to be stopped.
