Read this manual before using your oven. 2. As with all electrical appliances, it is wise to have the electrical connections inspected periodically. The oven interior and door seals should be cleaned frequently, following the instructions described in the CLEANING section. There is no need to switch off your oven after each function but remember to switch off at the end of the day or period of operation. 3. 4. 5. Microwave energy should not be used to dry linen or warm plates. 6. As with any cooking appliance, care should be taken to avoid combustion of the items within the oven. If smoke is observed:
Switch off
Isolate from the electrical supply
Keep the door closed to stifle any flames Ensure food is placed in the centre of the oven cavity for best results. 7. 8. When using the microwave only function, cover the food to prevent splashing the 9. walls of the cavity. Food in combustible plastic or paper containers should only be used in microwave only function and checked frequently to avoid the possibility of ignition. Items should be unwrapped when using convection and combination functions. 10. 11. Eggs and whole hard-boiled eggs should not be heated using the microwave or combination function as they may explode. 12. Food with a skin, e.g. potatoes, apples, sausages, etc. should be pierced before heating. 13. Food should not be heated in a completely sealed container as the build-up of steam may cause it to explode. 14. Excess fat should be removed during roasting and before lifting heavy containers 15. from the oven. In the event of glass breaking or shattering within the oven, ensure that food is totally free of glass particles. If in doubt, dispose of any food that was in the oven at the time of the breakage. 5 INSTALLATION Remove packing material and protective film from the oven. Included inside your oven:
Check for obvious signs of transit damage. If necessary, inform the freight company IMMEDIATELY. LOCATION AND POSITIONING Choose a site away from major heat sources. DO NOT position so that hot air is drawn in from fryers, grills, griddles, etc. A heat barrier to the height of the oven must be installed if sited next to a burner, stove or range. Note:
The air intake is located under each side of the oven, even with the clearance specified below it is important that airflow is as cool as possible and not pre-
heated by other appliances such as fryers, grills and griddles as this will deteriorate the life and performance of the oven. WARNING:
Check that the AIR FILTERS are in place prior to operation
( see Main Features ) Place the oven on a flat surface that is LEVEL, STRONG and STABLE. Allow a minimum clearance of 2 inches (50mm) to the rear, top and each side to allow air to circulate freely. The air intake is located under each side of the oven, even with the clearance specified above, it is important that airflow is as cool as possible and not pre-heated by other appliances such as fryers, grills or griddles. Allow a minimum of 2 inches (50mm) clearance above the oven for hot air to escape. Allow sufficient clearance, 12 inches (305mm) in front of the oven for the door to open fully Do not affix labels/stickers to oven other than those applied by the manufacturer 6 SUITABLE COOKING UTENSILS Manufacturers instructions should be checked to determine the suitability of individual containers or utensils using each of the cooking functions. DO NOT place metal trays or containers on the BOTTOM of the oven as arcing may occur. The following chart provides general guidelines:
convection only com bination Heat resistant containers Toughened glass Vitreous ceramics Earthenware
(porcelain, crockery, china etc.) Metallic & Foil Trays Metallic trays (on oven runners) DO NOT USE ANY OTHER METAL OR FOIL CONTAINERS Plastic containers Rigid, boilable, plastic containers Disposables DO NOT USE Combustibles (paper, card, etc) Microwave-suitable cling film Other utensils Tie tags Cutlery Temperature probes Do not use items with metallic decoration. Metallic trays may only be used when placed on the vitreous rack in the oven cavity ( See note ) Dual-ovenable plastic containers
(up to certain temperatures) are now available. Check manufacturers instructions before use DO NOT USE disposable packaging or metal foil containers No kitchen utensil should be left in food while it is cooking IMPORTANT The oven will accomodate size bun/sheet pans. Metal sheet pans may be used when placed on the special vitreous enamel shelf rails ONLY, either in Convection only mode or Microwave/Convection mode. 7 INTRODUCTION This oven offers operators the flexibility of combination cooking with additional control over fan speed and microwave power. Combination cooking enables high quality results to be achieved in a fraction of the time taken by conventional cooking, particularly when baking, browning, roasting, grilling or producing gratinee dishes. Once established, precise instructions for combination or convection cooking of selected items may be programmed into the ovens memory so that they can be repeated easily and accurately. Up to 100 programs can be stored and simply recalled by pressing a two digit number ( 00- 99 ). Multi-Stage Programming The oven controls offer even greater flexibility by allowing multi-stage programming. This enables the exact conditions required for quality results to be set according to the food type. Programs can have up to 4 stages each with its own time, fan speed and microwave power settings. A simple 2-stage program is shown:
With the oven set to pre-heat at 500F. Stage 1 The cooking stage begins by applying a gentle fan speed of 20% for 1 minute. Stage 2 The fan speed is increased to 80% for 30seconds to brown the food. This is only one example of an infinite number of possible multi-stage programs that can be created and stored. The instructions outlined in this guide are intended to ensure the safety and long life of your Merrychef oven. 8 MAIN FEATURES 7 6 12 2 3 4 11 1 8 Rear view 5 9 10 7 8 9 10 11 12 ON/OFF SWITCH When switched ON, the control panel will illuminate.

(see PAUSE FACILITY). The audible warning can be stopped by touching the cancel pad but it is important to remember that food in the oven will continue to brown until removed. PAUSE FACILITY A cooking cycle may be interrupted by opening the door. This facility is useful when stirring, repositioning or if temperature readings are required during a heating cycle On opening the door the timer will be held at this point and the display shows door open. TO CONTINUE To continue the cycle or program close the door an audible warning sounds as a reminder to press the START PAD to restart the timer. Hints and Tips for improved operation Care should be taken when defrosting in a hot oven. For best results, defrost first thing in the morning when the oven is still cold. Combination and convection only cooking may be carried out on a rising temperature but extra attention must be given to timings. Convection only cooking can be carried out without setting a time. Microwave heating may be introduced part-way through a manually set convection only cycle. However, we strongly recommend that only the most experienced microwave operator uses this facility as the microwave energy will then be on a time set for convection cooking. Cooking may be interrupted by opening the door. Close the door and touch the start button to continue. 13 PROGRAMMING NUMBER PADS 1 Pre-programming allows repetitive cooking procedures to be stored for ease of use. Each program can comprise up to four stages, allowing at each, independent control of Stage time, Microwave power level and Fan speed. However, programs must be used with caution, since if the food to cook varies in weight or density, adequately cooked food may not be achieved. Therefore, it is vital that all food prepared for service should be checked to ensure that core temperatures have been achieved.
