Intended Use
he Refrigerators/Freezers described in this manual are for
professional use only. hese products are intended for use in
research for the storage of samples or inventory in the following
temperature ranges:
Refrigerators +1°C to +12°C
Freezers -12°C to -20°C

Warning
Only Explosion Proof Units or
Flammable Material Storage Units
are to be used for the storage of
flammable inventory/samples.

Unpacking
Save all packing material if apparatus is received damaged.
