The Janoel12 (or JN12) incubator is manufactured by Yueqing Janoel Electrical Co., Ltd, also known as “Chonka” or “Guangzhou Kawa Electronic Technology Co., Ltd.”.
For automatic turning, it rolls the eggs continuously right and left across the incubator. The instructions imply that it takes 9 eggs, but if the eggs touch sides at any point, they can become stuck and stop turning so it is important to ensure that they do not touch the sides of the turning frame.
For manual turning, I sit the eggs fat end up in egg boxes, put a rubber band around the incubator (so that the lid is firmly attached to the bottom) and turn the whole incubator, popping the front or back up on a wooden baton. For manual turning, I also remove the turning rod because there is a chance of it damaging the eggs (this has happened twice to me).
Here is how many eggs I found it can take using both methods:
|Poultry||Automatic turning||Manual turning|
|Chickens (medium eggs)||6||15|
|Chickens (small eggs)||9||15|
The instructions are a bit funky, so here is my interpretation of them:
Incubator operating instruction
Before you start
Unpack the box and check the incubator. Check whether all of the parts are present.
When ambient temperature is lower than 20°C, you should take measures to keep the temperature more stable. Wrap the bottom half of the incubator in cloth (towel or a sheet). Make sure that the air hole on the top is not covered!
Use a thermometer to calibrate the temperature display before use. You can adjust the CA setting to correct it.
The incubator can be used after a 24 hour trial run during which you should aim to finish calibrating the incubator.
- Place the bigger plastic mesh into the incubator, railes facing up (fig.1).
- Put the movable egg tray (fig.2) onto the mesh, between the rails, with the loop facing upwards.
- Insert the egg tray dividers (fig.3) into the movable egg tray as needed. Once the eggs and the dividers are inserted, the eggs should all line up end to end with 2mm of space to the side between the egg and the next rail. You may end up with a spare space on the end which is unused.
- When closing the cover (fig.7), the automatic turner rod must be inserted into the loop slot of the moveable egg tray, so that the egg tray can move to turn the eggs.
- Switch on the power supply after closing the cover, and set the temperature according to display instructions and Incubator technology.
- 3 days before the eggs are due to hatch, remove the eggs, the tray and the large mesh. Replace the large mesh with the small mesh that has feet, placing it feed down into the incubator. Replace the eggs into the incubator and add a small amount of water to the base to increase the humidity for hatching.
- Only the power supply marked on the incubator can be used, which is 220-240v
- Do not put anything on the power cable. Place the power cable where it will not be stepped on.
- Make sure that the socket and any extension leads that are used are not overloaded.
- If the incubator is smoking, or produces an abnormal smell or unusual noise, switch off the power supply and unplug the incubator. Contact the seller or a maintenance centre to enquire about repair.
- Do not touch the power line with wet hands.
- Do not expose the incubator to rain or sunshine.
- Make sure that the power supply is switched off before cleaning the incubator.
- The incubator can be used only in a well ventilated room.
- Do not block the air hole when the incubator is switched on.
