Safety precautions
a This equipment is designed for trained personnel only, who must know the
refrigeration fundamentals, cooling systems, refrigerants and possible damage
that pressurized equipment may cause.
b Carefully read the instructions contained in this manual; strict observance of
the procedures described is fundamental to the operator’s safety, the perfect
state of the unit and constant performances as declared.
c Before performing any operation, make sure that the hoses used for
connections have been previously evacuated and that they do not contain
non-condensable gases .
d Avoid skin contact; the low boiling temperature of the refrigerant (about -30°C)
can cause freezing .
e Avoid breathing refrigerant vapours.
f It is recommended to wear suitable protections like safety glasses and gloves;
contact with refrigerant may cause blindness and other personal injuries.
g Do not operate near open flames and hot surfaces; the high temperatures
decompose the refrigerant releasing toxic and caustic substances which are
hazardous for the operator and the environment.
h Remove the battery in case of long periods of non-use.
i Do not keep a low battery inside the instrument
j Operate the unit only in locations with suitable ventilation and a high number
of air changes.
k Before disconnecting the instrument from the system, recover the refrigerant
inside the system in order to avoid wasting it in the environment .
l During operations avoid release of refrigerant to the environment; this
precaution is required by international environmental standards and is
essential to avoid difficult leak detection in a refrigerant polluted environment.
m Protect the unit from dripping.
n Do not modify the calibration of safety valves and control systems.
o If you recover refrigerant from a cooling system equipped with a water
evaporator and/or condenser, it is necessary to drain water from the evaporator
and/or condenser or to keep the circulation pump running during the entire
recovery operation in order to avoid frosting.
