HUMIDITY
It is important to understand that there can be no hard and fast rule for the amount of water required in an incubator as the following variables
come into play:
• Ambient humidity in the room (affected by the weather and your local environment).
• The species of the eggs
• The porosity of the eggshells (can vary from egg to egg)
• The time of year (warm weather usually means high ambient humidity and eggs laid towards the end of the season tend to be more porous)
Requirement for water in the incubator can be monitored by either weighing the eggs (an egg should loose 13-15% of its weight during incu-
bation) or by candling (the air space should be approx. 1/3 of the egg by the time it is due to hatch).
On subsequent hatches you may wish to increase or decrease the amount of water, depending on your findings with your first hatch. If in
doubt, it is better to add too little water than too much – more eggs are lost through too high humidity than any other single
factor! Remember, the depth of water makes no difference to the humidity levels in the incubator; it's the surface area which counts!
Generally for manual humidity by natural surface , as already mentioned, it is enough to assemble the water system and fill the reserve
water tank with tepid water and wait for 2/3 hours in order to see the value indicated by the thermostat minilcd.
If the value is too low, it will be necessary to take away the cover on the internal water basin; if the humidity reading is too high, it will be
necessary to reduce the water surface, by using the metal cover of the basin.
It should be remembered that it is the surface area of the water which affects humidity, not the depth of the container or the volume of water.
For manual humidification, during the hatching period, if it is not enough the total surface on internal water basin, introduce under the hatching
basket another small water basin.
For the automatic humidity by ultrasounds, as already mentioned, after the connecting of the humidifier it's necessary to set up the required
humidity value in order to allow the nebulizer automatic activation at each request of air humidification coming from the MINILCD thermostat.
LOAD EGGS STORED NOT MORE THAN 7- 8 DAYS AND NOT LESS THAN 3 DAYS FROM LYING.
BEFORE INCUBATION, THE EGGS MUST BE STORED IN A LOCATION WITH TEMPERATURE BETWEEN 14 – 16 °C.

In order to regulate the humidity level inside the machine it is necessary to modify the basin's surface:
enlarging the surface water increases the humidity, reducing the surface area decreases it.
VENTILATION (OPTIONAL)
For the control of ventilation, the incubator model MG 100/150 B. Family is supplied with a fan speed regulator which should be switched to
maximum position during the incubation period (put it on "incubation" position).
The fan speed must be decreased during the hatching period, changing the position of the regulator knob in an anti-clockwise direction to
"hatching" position.
When batch hatching, the fan speed should not be totally decreased for the hatching period, in order not to damage the eggs which are in
incubation phase.
During the incubation period, it is necessary to ensure the optimum oxygenation level, which will vary according to the number of eggs loaded.
The springs in endowment allow to stop the eggs placed upon the single cradle if the row is not completely filled with eggs

Remember to turn the eggs twice per days, morning and evening, by the key on setting trays, if the machine were supplied with manual egg-turner
