PRECAUTIONS DURING OPERATION
1. Operating the pump for a long period of time with the delivery valve closed may cause damage to some
of the pump components due to overheating inside the pump.
2. Too many stops and starts can cause damage to the pump. Limiting the number of starts is recommended
in line with the following:
N ≤ 6 when P ≤ 10 hp
N ≤ 4 when 15 hp ≤ P ≤ 30 hp
N ≤ 3 when P>30 hp
N = startup/h
P = motor power

PRECAUTIONS DURING STORAGE
1. The pump body may fracture if the water inside freezes; insulate the pump or remove all the water from
the inside.
2. If you have any spare pumps, you must perform test runs on them on a regular basis and keep them
ready for use at all times.
3. When a pump remains off for a long period of time, you must take great care to prevent any oxidation
on the surface of the bearing, shaft, coupling, etc.
