Assembling and Installation Unpack the machine carefully. Check the delivery set. Remove protective film from all surfaces. Put at the dedicated place, lock all four swivel casters. Power requirements Power outlet must have grounding contact! Presence of grounding connection must be checked on regular basis! If supply cord damaged, it must be replaced by manufacturer, service agent, or qualified persons...
Turbine (blower) The turbine provides constantly circulating airflow inside the machine. This is a direct type drive; the blower sits on motor’s shaft. Rotational speed is controlled by the main controller of the machine. Chamber This is where popping happens. Airflow circulates through the chamber; air is being heated by heating elements.
Hopper Corn hopper can fit one standard bag of corn (22,68 kg / 50 Lbs). Equipped with feeding auger. Control panel 1. EMERGENCY STOP push button. 2. 4-digit LED display. Shows parameter values, alerts and notifications. 3. TEMPERATURE adjusting buttons, marked with up and down arrows.
Intended use Modes of operation During operation, the machine is operated in different modes: Heating mode Once machine is turned on, it automatically starts to heat up. Upon reaching certain temperature machine switches automatically to popping mode. Popping mode This is the main operating mode. Machine operates in cyclic way, process- ing corn kernels batch by batch.
Setup mode This mode is used for fine adjustment of the machine and also to test feeder and sifter. For more details see Technical manual section. Operating parameters Properly chosen parameters are essential for good quality product and stable operation process. Popping temperature and basic turbine speed are the parameters available for an operator.
Quick start instructions 1. Empty the scrap tray. 2. Fill the hopper with corn kernels. 3. Put empty plastic bag into popcorn cart and put the cart under the sifter. 4. Press the START/PAUSE push button to turn the machine on. 5.
Display notifications Popper has 4-digit 7-segment LED indicator located on the front panel. During the operation, the following messages may appear: Reading Meaning Action required Machine is in heating mode None HHHH Machine is in cooling mode None CCCC POPP (glows) Machine is in popping mode None POPP (blinks)
Popcorn quality Popcorn is a product that requires ultimate attention towards many as- pects. Understanding popcorn processing technology is essential to get high quality product. Raw corn It is impossible to get good stable result using low quality supplies, first of all, raw corn kernels.
Maintenance and cleaning DO NOT use excessive water while cleaning! ALWAYS unplug the machine from the mains before cleaning! DO NOT use sharp tools or abrasives! Wait until machine is cool before cleaning! The purpose of maintenance and cleaning is to keep machine in good condi- tion during all the lifetime and to meet safety requirements.

VFD unit setup Run the machine in setup mode (the drive must be stopped). To change or view parameter value, press ENTER, the display shows 00.__ Then use up or down keys to choose the first two digits of the parameter (for example, 02.).
Temperature limiter setup Temperature limiter have three setting groups: first setting group, second setting group, and SV setting group (the main indication mode). The set- tings must be changed in the same order as they appear in the list. Note that after changing In-t (temperature sensor type) or UnI-t (temperature unit) values, parameters H-Su, L-Su, AL1, AL2, AHYS must be set again.
Optical amplifier setup 1. Operation indicator 2. Incident level scale 3. Adjustment knob (8-turn) 4. Timer switch (must be in OFF position) 5. Mode switch (must be in L position) To adjust the optical amplifier, put a folded sheet of white paper in the chamber as shown on the picture below, so the sight line of the sensor is interrupted with this paper screen.
