3. Natural surface humidification is performed by modular basins built into the machine lower
valve by an easy to use external filling system.
4. On the new developed VO Version the LCD electronic control unit can perform the digital
reading of humidity expressed in UR% (range 20-90%) and, if connected to an external
ultrasound humidifier, it is a super-modern digitally-regulated automatic humidification
system.
5. Insert the dial hair hygrometer into its metal support on the right frontal size.
6. Synthetic h ir hygrometer regener tion: in order to enable an exact humidity reading it’s
important at each incubation start to regenerate the dial hair hygrometer. A simple
regeneration is possible by storing the device several hours in wet atmosphere for instance
in bath rooms, wash houses or in the open air on humid foggy days or faster by wr pping
the device in wet towel for bout ½ hour. After this time the hygrometer must indicate a
relative humidity of max. 95 – 98%. Deviations can be corrected by turning the adjusting
screw with a small screw driver. The adjusting screw is visible through a small hole in the
back of the housing.
Once the machine has reached the working temperature place the eggs lying on the wire mesh
in horizontal position, between the rods of the adjustable egg turning grid.
When partially loaded of eggs check them to be closely positioned in the middle of the turning
grid to get the best possible movement of the same by proper egg weight distribution on the
turning grid.
To accommodate eggs of different sizes the Cosmo’s removable turning grid is supplied with
dividers which the user can position to suit their eggs.
ATTENTION: the correct working temperature for Cosmo model is fixed to 99,7°F
(corresponding to 37,7°C)
USE AND CALIBRATION
Plug the incubator into the electric power and allow the machine to run at the correct
temperature before setting the eggs.
The analogue thermostat (LCD for the EVO version see instructions for the calibration on the
next paragraph) , placed on the top valve, has been set up by the factory and indicates when
the machine is working (the led power results lighted). The continuous or intermittent lighting of
the led – ON – points out the heating activation.
Check that the set temperature on the thermostat dial agrees with the reading on the alcohol
thermometer inside the incubator. If necessary, adjust the set temperature slightly by using a
screwdriver in the central white screw on the thermostat box until the thermometer reads
99,7°F. It’s important to check the temperature on the thermometer in the incubator.
IMPORTANT : if all instrument setting attempts result useless, do not remove absolutely the
thermostat from its place to effect any improper or not authorized operation, just contact the
builder for a possible reparation or substitution.
