Commercial Microwave Technical Information ACE5140 / DS1400E / UCA1400 All safety information must be followed as provided in Service Manual. ! WARNING To avoid the risk of electrical shock, personal injury or death; disconnect power to oven and discharge capacitor before servicing, unless testing requires power.
Quick Start Reference Guide Refer to Product Safety Manual for Safety Statements Complete Owner’s Manual available online Oven Wall Clearances A B C A—For North American (UL/CSA) models, allow at least 2” (5.1 cm) of clearance around top of oven. For International (50 Hz) models, allow at least 7” (17.8 cm) of clearance around top of oven. Proper air flow around oven cools electrical components. With restricted air flow, oven may not operate properly and life of electrical parts is reduced.
Quick Start Reference Guide Refer to Product Safety Manual for Safety Statements Complete Owner’s Manual available online Cleaning Teflon Coated Oven Cavity (some models) • Wear protective rubber gloves when cleaning oven. • Use only a plastic utensil or nylon scouring pad to aid in removing soil or build-up from the oven interior. • Do not use knife, metal utensil, or steel wool pad to remove baked on material. This will damage the teflon coating.

Power Test ! WARNING To avoid risk of electrical shock, personal injury or death; disconnect power to oven and discharge capacitor before servicing, unless testing requires power. Power Test All Amana and Menumaster microwave oven power outputs are rated using the IEC705 standards. Using the IEC705 test method requires precision measurements and equipment that is not practical to be performed in the field. Using the test shown below will indicate if the oven performance is satisfactory.

Installation Unpacking Oven • • • • Inspect oven for damage such as dents in door or inside oven cavity. Report any dents or breakage to source of purchase immediately. Do not attempt to use oven if damaged. Remove all materials from oven interior. If oven has been stored in extremely cold area, wait a few hours before connecting power. ! WARNING To avoid risk of electrical shock or death, this oven must be grounded and plug must not be altered.
Display and Features B C D A E G A—Oven Door Handle (Lift to open.) B—Rack Guides C—Top Control Panel D—Display E—Side Control Panel G—Air Intake Filter (some models) Oven Features Standby shows in display after oven door has been opened and closed, or after turning oven OFF with the Preheat On/Off pad. Standby Oven Preheating 230°C Oven Preheating and set temperature shows in display after pressing Preheat On/Off pad.
Display and Features Ready and set temperature displays after pressing Preheat On/Off pad. Ready indicates the oven is up to temperature. (example of 230°C shown) (cont’d) Ready 230°C Indicates oven is in a preprogrammed cooking program Item-05 Stage:1 01:23 230°C MW:50% Time left in cooking program Cooking temperature Cooking information shows in display after pressing a single (or double) digit pad while in Ready Mode.
Display and Features Start pad The Start pad is used to begin a manual time entry cooking cycle. Stop/Reset pad The Stop/Reset pad stops a cooking sequence in progress, clears out any remaining time, and also ends a programming or user option cycle. When the Stop/Reset pad is used to end a programming or option change, the changes are discarded. Temperature warnings The combination oven has two distinct temperature warnings. Warnings sound with a three beep signal when a programmed pad is pressed.
Programming Programming Pads Oven is shipped from the factory for single pad programming. To change the oven default to double pad programming, see User Option section. To program the amount of time, power level, or temperature setting for a pad: 1. Oven must be ON. • Press Preheat On/Off pad. • Oven Preheating 230°C shows in display with Oven Preheating flashing. (example of 230°C shown) 2. Oven reaches preheat temperature. • Signal sounds and Ready 230°C shows in display with Ready flashing.
Convection Cooking ! CAUTION To avoid risk of burns, handle utensils, racks, and door with care. Allow oven, utensils, and racks to cool before cleaning. Oven, utensils, and racks, become hot during operation. To operate the oven for convection cooking only, you can use preprogrammed pads or manual time entry. The following instructions are for convection cooking only. For combination cooking, see that section.
Combination Cooking ! (microwave and convection) CAUTION To avoid risk of burns, handle utensils, racks, and door with care. Allow oven, utensils, and racks to cool before cleaning. Oven, utensils, and racks, become hot during operation. To operate the oven for combination cooking, you can use preprogrammed pads or manual time entry. The following instructions are for combination cooking only. For convection only cooking, see that section. Combination Cooking With Preprogrammed Pads 1.
User Options Changing user options Didn’t like an option? Factory settings are marked in bold. To change the oven back to the factory setting, simply select the option that is marked in bold. ? My changes weren’t saved. In order for any changes to be saved, the Program Save pad must be pressed after selecting an option. Pressing the Stop/Reset pad will not save changes.
EZCard Operating Instructions (some models) Update programs in seconds! EZCard slot To program the oven using the EZCard: Oven must be in Standby mode (Preheat must be OFF) 1. Remove protective cover from bottom of vertical keypad. 2. Insert the EZCard into the slot located below the vertical keypad. • The EZCard can be inserted forwards or backwards. 3. Press and hold the Program Save pad for 3 seconds.
User Maintenance Moving Oven Rack Guides (some models) The oven rack guides can be moved to one of three positions within the oven, allowing for versatility in cooking and placement of food. The middle rack position is the most common. Guides can also be removed for easier cleaning. To remove rack guides: 1. Oven cavity must be cool to touch. 2. Remove oven rack by lifting up and sliding to the front of the oven. 3. Apply gentle pressure by pulling upwards on the front of rack guide. 4.
Care and Cleaning Clean oven frequently to maximize oven life, performance, and efficiency. A dirty oven cooks inefficiently because moisture, spills, and grease absorb convection and microwave energy. ! ! WARNING To avoid electrical shock which can cause severe personal injury or death, unplug power cord or open circuit breaker to oven before cleaning oven. CAUTION To prevent burns, handle utensils, racks, and door with care. Allow oven, utensils, racks to cool before cleaning.
Before Calling for Service ! WARNING To avoid electrical shock which can cause severe personal injury or death, do not remove outer case at any time. Only an authorized servicer should remove outer case. Problem Possible Cause Confirm oven is plugged into dedicated circuit. Oven does not operate. Confirm oven is on grounded circuit. (Contact electrician to confirm) Check fuse or circuit breaker. Oven operates intermittently or HOT shows in display.
