MIDI F90 incubator
These machines are more advanced to regular incubators because they have an egg-turning device and so the egg-turning happens automatically. 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 temperature display is on the main page of the operating panel. The control buttons are underneath the panel.
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.
This feature can also be used as a remote alarm device.
The cooling-fan module should be connected to the outlet that is located on the machine.
It is able to turn the eggs. Place the eggs in the egg-trays, and then push in the trays with the tilting bolt going in first. Move the cradles so that the bolt will slide into the groove of the tilting mechanism. After this the egg-turning connection is done.
By switching the machine on, the turning device is switched on as well; it completes a full circle in two hours. It operates non-stop and tilts the eggs to left and right up to 45 degrees.
The humidity measurer should be placed behind the checking window, which is on the door of the machine. Place the water-filled water tray to the bottom of the machine. The humidity measurer will show the humidity level.
There is an adjustable cover on the air outlet; by opening and closing this you can adjust the amount of the air that flows through and refreshes the interior as well as the humidity level. If you close the outlet hole, the humidity level increases; if you open it, the humidity decreases.
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!
The 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.
