NOTICE
Be sure the pump is filled up with water before
starting the engine or mechanical seal damage will
occur.
TIP
9 Place the water pump on a secure, flat and level
surface as near to the water to be pumped as pos-
sible.
9 The higher the water pump is from the water sur-
face (more suction head), the longer it will take to
prime and the lesser pump output (discharge
head) will be.
