HFC user manual
• The visors, minimum level indicators and spouts with disc of the containers include
removable connections with joints that normally resist the pressure and temperature
requirements of the fluids. In these removable connections with joints, we can not ex-
clude that by their very nature they lose their tightness over time. That is why you must
tighten these connections before and after commissioning. The tightening torques may
be different. For the case of the visors (with gaskets mounted in the liquid receiver and
in the general line of liquid) a torque wrench should be used to prevent the steel rim
from overloading, breaking the glass lens. The official regulations that may be neces-
sary for appliances under pressure and the periodic controls that must be carried out
are regulated by laws and / or national regulations of the State where the system is
installed. Compliance with these laws, regulations and technical regulations are the re-
sponsibility of the manager.
• The end user must protect the system from fire hazards coming from outside.
