Pressure Vessel and Safety Device: This heat pump 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 heat pump 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 maximum allowable
pressure(refer to nameplate) to the system, by modifying or changing
the high pressure switch.
• Start-up and Operation: Check to ensure that all the stop
valves are fully opened and no obstacle exists at the inlet/outlet
sides before start-up and during the operation.
• Maintenance: Periodically check the high pressure side
pressure. If the pressure is higher than the maximum allowable
pressure, stop the system and clean the heat exchanger or
remove the cause.
