Startup process.
In case the compressors do not start when the Freezer has been plugged in, the electrical
supply may not be in order. Check if there is an electricity supply to the plug or if the fuse is
blown.
Before starting the unit, you must check and decide below parameters:
1. SET TIME: Must change to local time zone.
2. SET TEMP: Change the set point for the desired temperature in the chamber.
3. ALARMS: Change High and Low temperature alarm level.
4. ALARM DELAY: Change the time delay from the temperature reach High or
Low Temperature alarm level, to the alarm will be activated.
5. DOOR OPEN ALARM: Enable the door open alarm and the delay for the alarm will be
activated.
During the Freezer is starting up from Ambient level (RT +20°C), the High Temperature alarm
will be activated several times before the temperature reach the High temperature alarm level.
Operating the Freezer
The Empty Freezer should be switched ON for cooling down the chamber, for at least 8-10
hours, prior to loading ballast into the chamber of the Freezer.
Please note: After the door has been opened, there will be a vacuum created inside the Freezer
due to the low temperatures. Wait a few moments before trying to reopen the door otherwise
the handle or gaskets could be damaged.
