Installation
● Do not install the pump in a corrosive or flamma-
ble gas atmosphere. Keep good ventilation in a
working area. Ambient temperature should not fall
below 0°C or exceed 40°C. Observe the allow-
able gas temperature range of 0 and 40°C.
● Observe the rated voltage specified on the name
plate. Applying any voltage than the rated one
may result in failure.
● The pump can not start when the pump head is
pressurized by line pressure. Remove pressure
before operation. After a long period of stoppage,
pump performance at the beginning of opera-
tion becomes occasionally unstable. In this case,
warm the pump up for 10 minutes with no dis-
charge line pressure.
● Surface temperature may rise high in operation
but it dose not mean failure. Do not touch the
pump body directly or place objects which may be
deformed by heat close to the pump.
● Always use a suction valve to adjust an air flow.
● The APN-S450 is designed for vacuum applica-
tion only. Do not connect the pump's outlet with a
pressurized discharge line.
