Preperation:
1. Shaft Outside Diameter is within tolerance +-0.05mm
2. Shaft run out <0.1mm
3. Shaf end float <0.13mm
4, No sharp edges on the shaft over the o ring
Note:
During the installation,don't scratch or damage the o ring.lf

3. Place the cartridge seal into the pump chamber,then:
A: Tighter four screw bolts of flanges,ensuring the medium leading
in hole"G"at the top Position
B : Tighter four set screws and position the shaft sleeve on the

C: Remove four gauge plates.Please keep them and they wil be used
in future installation and
