MIDI F500S incubator.
These machines not only check and control the temperature and the egg-turning automatically, but measure and supervise the level of humidity.
They have a complex security system as well as interior lighting.
The letter S in its name refers to its capability of measuring and automatically controlling humidity level. Letter F indicates the automatic egg-turning.
The engine box of the “MIDI” line incubators is made of 19 mm thick sandwich-panels that are glued together (the outer and inner side is polystyrene sheet, with extrudated polyurethane foam insulation in the middle).
The joint gaps of the panels are water-tight. The engine box stands on rubber legs.
The central fan—which is inside the incubator—controls the even temperature by turning the air and it also ensures the airing of the machine. The pipe heater responsible for heating of the incubating area is located in the intensive air-flow of the fan.
The main switch is located on the side of the control box; this starts all functions of the machine, such as the air-turning fan, the control of heating and humidity level, egg-turning, interior lighting, etc.
The temperature display is on the main window of the operating panel, next to the humidity display. The control buttons are underneath the panel. In a few seconds after setting the required values, the display returns to showing the actual measurements while following the instructions.
The machine does not operate with an open door! If the door is open, a sensor shuts down the fan, the heating and the turning.
Setting the temperature can be done by moving up or down with one tenth of a degree. The control device keeps the set temperature with a +/- 0, 1 C degree accuracy.
The temperature controller functions as a safety device, it protects against dangerous temperature increase by shutting off the heating and starting the fan to blow in cool air, and it also sets off an alarm!
This feature can also be used as a remote alarm device.
The automatic humidity controller measures and shows the relative humidity and can increase the humidity of incubating area by turning the humidifying discs.
If a power shortage happens while the incubator is being used, the machine shuts down, but after the power is back, the incubator starts up again with the originally set values. So the incubator “remembers” the previously stored information.
The last three days are for the hatching period. In this period you must place the eggs from the turning tray into the hatching tray and have them hatch there—the eggs cannot stay in the turning trays!
It’s best if hatching is done in a separate machine. Hatching is a hazardous process which requires regular cleaning and sterilizing.
The incubator belongs to the group of air-turning, boxed-machines, thus its technological data applies accordingly.
Operating instructions are found in the Manual, attached to the machine.
