Temperature Control

The freezer temperature can be adjusted by the Cold Control
Knob. Freezer temperature will become lower as the control
Knob is set closer to the "MAX" position.

Manual Defrost Procedure

For the most efficient operation and minimum energy
consumption, defrost the freezer when the frost on the freezer
walls is excessive or 1/4" thick.
1. To start defrosting, unplug the freezer and remove the
samples.
2. Use a sponge or towel to remove water and melting ice
from the freezer floor. After the frost or ice has melted, dry
the interior of the freezer thoroughly.

3. When defrosting is complete, remove drip tray and
dispose of water. Set cold control back to original
position.
CAUTION: Do not use any sharp instrument,
blade or scraper to remove ice and frost on
freezer surfaces because of the very real danger
of puncturing the cooling coil.
CAUTION: Do not use any electrical device to
defrost the unit.
When frost accumulates, to 1/4" or more, the
operating efficiency of the unit will be affected.
