• Pressure Vessel and Safety Device: This air conditioner is
equipped with a high pressure vessel under PED (Pressure
Equipment Directive). The pressure vessel has been designed
and tested before shipment according to PED. Also, in order to
prevent the system from an abnormal pressure, a high pressure
switch, which needs no field adjustment, is utilized in the
refrigeration system.
• Therefore, this air conditioner is protected from abnormal
pressures. However, if abnormally high pressure is applied to
the refrigeration cycle including the high pressure vessel(s),
it will result in serious injury or death due to explosion of
the pressure vessel. Do not apply a pressure higher than the
following pressure to the system, by modifying or changing the
high pressure switch.
