To reach best hatching result, please read the manual carefully before using.
1. Package included S30/52 egg incubator*1, Styrofoam*1, 2. Power code socket
power code*1, user manual*1, water bottle*1
3. Ensure fan, temperature & humidity displaying, function keys, 4. Add full water into water tank, close the cover.
heater works well. Motor rotates for 10-13 seconds (every two hours) Run machine for 10-30 minutes in advance for
hatching .

Attention：
1. Ensure disconnecting power before opening the cover.
2. Hatching eggs must be fertilized eggs.
3. When finish hatching, the cover and bottom must be air-dried separately to prevent the electronic components from being damaged
by internal moisture of the machine for a long time.
Incubation Tips:
1. Please choose fresh fertilized eggs laying within 4-7 days generally. Keeping fertilized eggs at 10-
15℃is recommended. Washing or putting it into fridge will damage the powdery substance
protection on cover ,Which is strictly prohibited.
2. Ensure fertilized eggs surface are clean without deformity, cracks or any spots.
3. Incorrect disinfection mode will reduce hatching rate. Please ensure eggs are clean and without
spots if without good disinfection condition.
4. Ensure eggs are pointy side down when hatching.
5. Please add water to the machine every 1~2 days (it depends on the environment humidity and
water content inside the machine).
6. Manually turn eggs twice per day gently and slowly (Keeping fertilized eggs pointed side down,
swing left and right side at 45°around 3-4 times).
7. Do not test eggs in first 4 days. Incorrect egg testing timing will lead to temperature decline,affect
eggs’early development.
a.Test eggs in 5th-6th days,check the fertilization of the eggs,take out unfertilized eggs, scattered
yellow eggs, dead eggs
b.Test eggs in 11th-12th days, check inner eggs development. Well-developed embryo is enlarged
with blood vessels inside, and the air chamber is large and sharply demarcated.
c.Test eggs in 16th-17th days, put pointy side of egg toward to light source.Well-developed
embryo is getting larger and filled up the eggs inside with dark area mostly. Dead egg is with
blurred blood vessels,yellow air chamber around, unclear boundary between egg inside and the
air chamber.

8. Increase humidity and decrease temperature during last hatching period, to avoid insufficient
water when baby chick is pecking the egg shell,and to prevent dehydration in long hatching time.
9. Temperature should not be exceed to 37.5℃in 19th-21th days.
10. Do not open the cover frequently when the incubator is working.Unplug the machine when
opening cover.
