Haier DW-150W200 Operation Manual page 12

2.8 If the freezer is required to reach its minimum temperature, e.g. –150 ,
sure that ambient temperature is below 25 ,
days for stable working state and starting/stopping. If stable, change the temperature to -150 .
Note: Unless especially required (operating temperature -150 ℃ ), it is advisable to set the
operating temperature above –145 ℃ , otherwise that may have a negative influence on both efficiency
and service life of the freezer.
3. Condensate removal:
In case of high ambient humidity, the anti-condensation switch at the rear of compressor compartment
should be turned on to prevent condensate forming at the top opening of cabinet.
4. If the SLT freezer is not to be used for a relatively long time, the battery switch at rear upper of
compressor compartment should be turned off, otherwise the battery charge would be used up, and thus
the battery could not be used any longer and recharged again.
Tips:
For any product may go wrong or fail to work, please follow the instructions below in order to avoid any loss
resulting from faults of the freezer:
1. The freezer must not be installed in a narrow space, and the door of room where it is installed must not be
smaller than the freezer, but at least ensure normal handling to avoid such problems as difficult servicing, failure
to repair it in time and damage of articles stored in the freezer, etc.
2. The freezer should be attended by a qualified person and its operating status must be checked and recorded
every day (check and record once every 2-4 hours). In case of any fault or power failure, the internal
temperature would rise; if the fault may not be cleared in a short time, please take out stored articles and move
them into other devices meeting the temperature requirement of these articles to prevent degeneration or
damage.
3. Before putting articles into the freezer, please make sure their temperature requirement is consistent with the
freezer's temperature range in order to prevent them from degeneration or damage due to the freezer's failure to
reach the temperature required by them.
4. Due to refrigeration inertia, it is normal that there is certain difference between the temperature actually
indicated and temperature setting (the lower temperature setting, the smaller temperature difference, whereas the
larger temperature difference).
