Post-assembly checks

Perform these checks after you assemble the pump, then continue with pump startup:
• Rotate the shaft by hand in order to make sure that it rotates easily and smoothly and that there is no
rubbing.
• Open the isolation valves and check the pump for leaks.

Reinstall the back pull-out assembly for the HT 3196

1. Attach the casing support (239) to the casing (100).
The stamped part number on the casing support is located on the left side when you face the casing
suction.
2. Reinstall the coupling guard.
Refer to the Install the coupling guard section for more information.
NOTICE:
Risk of damage to the mechanical seal or shaft sleeve on units supplied with cartridge mechanical seals.
Prior to startup, make sure to tighten the set screws in the seal locking ring and remove the centering clips.
