Page Safety standards
1 The equipment is aimed exclusively for
professional fi tters that must know the
principles of refrigeration, refrigeration
systems, refrigerant gases and likely dama-
ge caused by pressure equipment.
2 The present manual must be read tho-
roughly, strict observance of the steps
herewith described being an essential
condition for user safety and equipment
integrity, as well as maintaining the stated
performance.
3 Using applicable protections, such as
goggles and gloves, is recommended; co-
ming into contact with the refrigerant can
cause blindness and other injures.
4 Always work away from fl ames and hot
surfaces; at elevated temperatures, the
refrigerant gas breaks down, releasing
toxic and aggressive substances, harmful
for users and the environment.
5 Avoid skin contact; the low boiling point
of the refrigerant liquid (about -18ºC/-
3ºF), can cause frostbite.
6 Avoid inhaling refrigerant fumes. Narcotic
effect.
7 Keep the scale dry. Water or any other
liquid would damage electronic compo-
nents.
8 Keep the scale away from disturbances
such as, vibrations, magnetic fi elds, corro-
sive gases and liquids, etc.
