18. Defrosting at refrigerating operation
BINDER constant climate chambers are very diffusion-proof. To ensure high temperature precision there
is no automatic cyclic defrosting device. The DCT™ refrigerating system largely avoids icing of the evap-
oration plates. However, at very low temperatures the moisture in the air can condense on the evaporator
plates leading to icing.
Always close the door properly.
Operation with temperature set-points > +5 °C / 41 °F at an ambient temperature of 25 °C / 77 °F:
The air defrosts the ice cover automatically. Defrosting is continually performed.
Operation with temperature set-points < +5 °C / 41 °F:
Icing on the evaporator is possible. Defrost the chamber manually.
With temperature set-points < +5 °C /
41 °F
, regularly defrost the chamber manually:
•
Set the humidity to 0 % r.H. The humidity system must be activated.
•
Set the temperature to 40 °C /
104 °F
(Manual Mode).
•
Let the chamber operate for about 30 minutes with the door closed.
Too much ice on the evaporator is noticeable by reduced refrigerating performance.
When turning off the chamber following prolonged refrigerating operation below +5 °C /
41 °F
, there is
danger of overflowing due to uncontrolled defrosting of icing on the evaporator.
CAUTION
Uncontrolled defrosting of icing on the evaporator.
Danger of overflowing.
After several days of refrigerating operation below +5 °C /
41 °F
:
∅
Do NOT directly turn off the chamber.
Manually defrost the chamber (see description above).
Then, shut down the chamber at the main power switch (1) and close the tap of the
water supply. Keep removed the access port plugs.
KMF: Operation with temperature set-points below 0°C / 32 °F:
While operating the chamber with set-points below < 0°C /
32 °F
condensation is possible at the inner
surface of the door around the door gasket.
In case of heavy condensation, check tightness of the door gasket.
After one or two days operation at a set-point < 0°C /
32 °F
a thin ice layer can cover the inner chamber
door , the front margins of the inner kettles and may be the glass window.. The amount depends of the
ambient temperature and humidity. This does not influence the proper function of the refrigerating sys-
tem.
Refrigerating performance decreases while operating the chamber at temperatures < 0 °C /
32 °F
due to icing of the evaporators. For this reason defrost the chamber regularly, e.g. once
a week.
