8.3.3 Defrosting
Frost may form on the cooler in temperature operations below 40°C. Defrost the chamber in the following
cases.
•If temperature inside the chamber is uncontrollable or rises slowly.
•If air blowing from the chamber is weak (when the door is opened).
•If frost or ice form on the test area wall.
Use this procedure to defrost packing as well.
Procedure:
1. Check the chamber is plugged in.
2. Set target temperature to a minimum 70°C and turn OFF humidity control (not necessary with tempera-
ture-only chambers).
3. Set Chamber Run Switch to ON to start the chamber. Run the chamber for about 60 minutes with the
door closed, then for 15 minutes with the door slightly cracked.
