Measures against crossing of the refrigerant density threshold.
In order to keep the refrigerant density below the threshold value, please install a mechanic
ventilation device. (Perform ventilation often.)
In case frequent ventilation is impossible, please install the leakage detection alarm device
linked with the mechanical ventilation device.
5. Heat Insulation of Refrigerant Pipe
In order to prevent faults caused by condensate of the refrigerant pipe and drain pipe, perform
condensate prevention and heat insulation properly. If it is forecast that high humidity and
temperature environment (Condensate temperature is over 23°C) may exist in the ceiling, e.g., inside
the ceiling with slab, ceiling which is in the same environment as the outdoor air. It is necessary to
