Assembly
Assembly can be made in reverse procedures to disman-
tlement. Pay attention to the following points.
Gasket replacement
Always replace the gasket with new one every time
the pump unit is assembled. Do not twist or catch the
gasket in the parts. Clean the sealing surfaces before
mounting.
Tightening of bolts
Tighten the bolts diagonally and evenly.
Cleaning magnet capsule
Waste metal such as Iron pieces can be attracted to
the magnet capsule. Remove such foreign matters
before assembly.
1. Place the gasket in the front casing (100.1).
2. Put the impeller assembly in the rear casing. Fit the
rear casing together with the impeller assembly, rotat-
ing the rear casing right and left.
3. Mount the rear casing cover and the rear casing sup-
port. And then tighten the rear casing support mount-
ing hex. bolts by 85N•m diagonally and evenly.
NOTE: Loose the bolts (901.7) on the foot sup-
port before retightening the rear casing
support mounting bolt.
4. Remove foreign matters from the drive magnet on the
motor shaft.
5. Screw the two bolts (M12×100: for back pull out) in the
bracket half way. Direct the motor bracket to the pump
unit parallel.
6. Slowly close the motor to the pump unit by alterna-
tively unscrewing the two bolts (M12×100: for back pull
out).
Fit the motor straight to the pump unit so that the drive
magnet (858) does not come in contact with the rear
casing.
Fix the bracket and the rear casing support by mount-
ing hex. bolts.
After assembly, retighten the rear casing
support mounting bolts.
