The flow switch can be disassembled or replaced by using a “Din 1810 Form A
No.40 68-75 hook wrench” or other similar pipe wrench to unscrew the “Locking
Ring (Part No. 22-4)”
The filling of suction piping and pump chamber must be very carefully to ensure
no any air inside. Trapped-air will cause pump low discharge / pressure, and
resulting abnormal operation. Trapped-Air evacuation can be accomplished by
opening all discharge valves, or unscrewing the discharge side “Priming Plug
(Part No. 21-2)” during pump operation.
PROBLEM – Pumps fail to start when the discharge devices are opened.
