Light Switch - Grumbach MP GTFS Bedienungsanleitung

It is necessary that the stopper is fixed to its shut down temperature after the test run.
Please turn it very carefully, as a minimum turn already changes the shut down tem-
perature.
When you let the temperature rise with the thermo adjustment you can decide about
the exact shut down temperature. The shut down temperature should be at least 1 °C
above the incubating temperature because the feeler of the protective thermostat sits
next to the heating spiral and feels a higher temperature there than inside the breeding
room.
Tank flap
The flap is only to be used when you wish to reduce humidity while the tank is full.
Behind the knob is a flap which opens or closes the installed filler pipes. Position 
means "open". This adjustment is necessary if you use the automatic humidity, so
humid air can be blown from the tank into the breeding room. The six o'clock setting
means that the flap closes the tank and no unnecessary moisture enters the incubat-
ing chamber; additionally, the set value for the moisture must be reduced to 5 %. This
rotary control saves a pouring out of the water from the tank when the air humidity in the
breeding room has gone up.
Turning of eggs
There are trays situated in every incubator to hold the eggs. The ground of these trays
is made of covered punch metal. The eggs have to be laid on the rollers so that the
pointed sides are opposite the blunt sides; this prevents a rolling away of the eggs into
one direction. Always fill the trays from the middle to the outside to support the air cir-
culation.
The eggs should lie on the trays horizontally during incubating. It does not matter though
if the eggs are half diagonal- if done so the capacity is higher. Depending on the egg,
from the 1st to the rd breeding day, they can be turned. In manual machines the turn-
ing is done by pushing the egg tray to the back of the incubator, then pulling to the
front.

Light switch

The light switch works the light for the breeding room of the incubator. Please use the
light only for a short time and switch it off again when you leave the incubator.
Putting in the eggs
If the incubator has been working without faults during a - days testing period, you
can start to put in the eggs. Once the eggs are inside the incubator the temperature will
fall. There is no need to worry- because the incubator was open a lot of warmth has
escaped and the temperature of the eggs is much lower. It would be wrong to turn up
