Page 13: Handling Instructions
Handling instructions Because of the powerful magnetic force of this pump, extra precaution is necessary in addition to the normal one such as dry running or reverse rotation operation. People with pacemakers and other electronic devices for maintaining bodily functions do not use this magnet pump. -
Page 14: Installing / Piping Precaution
Installing / piping precaution Installing precaution (1) If a large amount of air enters in pumps, it does not pump properly and causes a breakdown. ⚫ The suction pipe is the state of the negative pressure. If air enters for the connection installing failure, liquid is not pumped, and the temperature of priming liquid is raised. -
Page 15: Operating Precaution
Operating precaution Before starting operation. (1) Clean pipes and tanks. If foreign objects enter the pump, not only the performance decrease, but also cause a breakdown. (2) Pour priming water from the priming water plug on the top of the suction casing and release air. From next time, it is not necessary to do it for the self-priming structure. -
