Mount the pump in the tank at least 1 mm
above the tank floor. This is to ensure
enough clearance to prevent the pump
from sucking the sediments of sludge or
metal chips on the tank floor.
To prevent the pump from drawing air,
install the pump in the tank water deeper
than 60 mm as illustrated in figure 5.
