1. The current time is displayed The first digit is flashed Saas See numerical value shift key digit changes The delay time is memorized and Press set key SET the current chamber temperature is displayed The start up may be behind the delay time set by the above procedure because the compressor is affected by the chamber temperature and temperature of cascade condenser installed in the freezer The high stage side compressor starts to operate without delay time at the time of power on or after power failure The set mode returns to the temperature display mode automatically when 90 seconds has passed without any key operation In this case any setting before pressing set key SET is not memorized 4 Press set key DEFROSTING NCAUTION Do not defrost inside walls using a knife or ice pick There are pipelines for cooling behind the walls Be careful not to damage the lines as this could cause a breakdown Also do not make a hole in the wall for installation of attachments Automatic defrosting Defrosting is carried out in a short period of time by a special heater built into the evaporator During defrosting the internal temperature may rise slightly but this has almost no effect on temperature of the stored items so leave them in the freezer during defrosting During defrosting dF and
