7. Measure distance between impeller and volute after assembly.
Keep a recommended clearance of 0.3–0.5mm (0.118–0.196in).
—If measured distance between impeller is greater than 0.5mm
(0.196in), pumping capacity drops.
—If measured distance between impeller is less than 0.3mm
(0.118in), impeller may contact volute and slow rotation,
overload motor causing premature failure.
