Intended Use
This product is intended for use as a General Purpose Laboratory Freezer
for storing samples or inventory between -40 and -86C.
This unit is not intended for use in an explosive environment, nor to be
used for the storage of flammable inventory. This unit is not intended
for use in a Class II medical application as defined by Title 21 of the
Federal Code of Regulations.
1 Installation category (overvoltage category) defines the level of transient overvoltage
which the instrument is designed to withstand safely. It depends on the nature of the
electricity supply and its overvoltage protection means. For example, in CAT II which is
the category used for instruments in installations supplied from a supply comparable to
public mains such as hospital and research laboratories and most industrial laboratories,
the expected transient overvoltage is 2500V for a 230V supply and 1500V for a 120V
supply.
2 Pollution degree describes the amount of conductive pollution present in the
operating environment. Pollution degree 2 assumes that normally only non-conductive
pollution such as dust occurs with the exception of occasional conductivity caused by
condensation.
