tm2692 Jan-20 1. Overview 1.1. Purpose Vortex Popcorn machine VPM-RM4 (Robopop® 60) (hereinafter “popper” or “machine”) is a hot-air popper for making popcorn. Both Butterfly and Mushroom varieties can be processed. Built-in automatic salt/oil application system allows making salted movie-style popcorn. Popper built on patented Vortex technology that has following benefits: - No oil is used at all.
tm2692 Jan-20 1.4. Power Requirements CONNECTIONS MUST BE DONE ONLY BY QUALIFIED ELECTRICIAN! ELECTRIC SOCKET MUST HAVE GROUNDING TERMINAL! IF SUPPLY CORD DAMAGED, IT MUST BE REPLACED BY MANUFACTURER, SERVICE AGENT, OR QUALIFIED PERSONS IN ORDER TO AVOID HAZARD! It is necessary to periodically check electric connections, including grounding connection.

tm2692 Jan-20 Chamber is equipped with temperature sensor and optical sensor. Chamber optical sensor The chamber optical sensor monitors processes happening in the chamber. Popper uses signal from this sensor in order to maintain smooth and effective operation process. Chamber temperature sensor Chamber temperature sensor helps to maintain the temperature in the chamber.
tm2692 Jan-20 each. Draw-out tray makes canister replacing easier. Heating elements below compartment are provided. Popcorn cart Two movable carts and 200 liter bags (LDPE) are included in the delivery set. Using two carts makes easier changing full bag for an empty one. The machine is equipped with cart sensor tripping whenever cart is full and needed to be replaced.
tm2692 Jan-20 2. Intended Use 2.1. Operation Modes The popper has following operation modes: - Heating mode. Once desired program button is pressed, popper automatically starts to heat up. Upon reaching certain temperature popper switches automatically to popping mode. - Popping mode. This is the main operation mode. - Pause mode.

tm2692 Jan-20 Program change To switch the program, press PAUSE button. Corn supply will stop immediately. It will take 3 minutes to finish processing of corn kernels in the chamber. After this, two program buttons, Butterfly and Mushroom, will appear on the screen. Cooling down To stop the operation, TURN OFF button should be pressed.
tm2692 Jan-20 2.3. Program settings Machine settings directly affect popcorn quality as well as machine operation. It is important to understand the way each parameter or setting affects end product and machine operation; and also the way how settings interact to each other.

tm2692 Jan-20 Using oil and salt Most kinds of liquid oil without any added powder may be used. IMPORTANT NOTE ON USING OIL! Oil pumping rate depends on oil thickness; it is very important to avoid oil temperature fluctuations to keep pumping rate the same. To be sure that oil is kept at the same temperature following conditions must be met: OIL WARM switch must be at ON position all the time, even at...
