Pump operation
After the pump has reached a specified stroke rate, initiate full
scale operation.
•
Always adjust an air flow by a suction valve.
• In case electric power has failed while the pump is running, switch
off main power. Otherwise, the motor may not restart or may burn out
depending on a line pressure at the time of power recovery.
After starting, check a pressure gauge to see if suction and dis-
charge line pressure are correct and an air flow meter to see if the
specified air flow is obtained.
Before a long period of stoppage (1 week or more)
Depressurize the system and stop air/gas supply. Do not install/store the pump:
• In a flammable/corrosive atmosphere.
• In a dusty/humid environment.
• In direct sunlight or wind & rain.
• Under vibration.
• Where ambient temperature can exceed 0-40°C.
