Section I - Assembly
Tools Required: Metric box wrench set & metric deep well socket set
- Pumps with Motors
1. No assembly required. Unpack the pump and motor and examine for any signs of shipping damage. If damage is
detected, save the packaging and notify the carrier immediately.
2. Proceed to the “Installation” section of these instructions.
- Pumps without Motors - 90, 100/112, 132 & 160 frame with B5 flange: All motors must have motor feet.
Very Important: Do not remove shipping plug located in suction port of the pump until the pump is completely assembled onto the
motor.
1. Unpack the pump and examine for any signs of shipping damage. If damage is detected, save the packaging and
notify the carrier immediately.
2. Insert key into motor keyway. (See Figure 1). Visually determine key location in pump end. Align keyway slots on motor shaft and
pump impeller sleeve. Slide pump assembly over the motor shaft until the pump motor adapter (item 8 for AC6 or 22 for AC8) is
completely seated over the motor rabbet. Install 4 bolts with flat washers and lock washers (items 9, 10 &
11 for AC6 or 19, 20 & 21 for AC8) through the face of the motor & into the motor adapter. Securely tighten bolts using
the torque specifications in the table below.
3. Lubricate o-ring of self-sealing bolt (item 6) with suitable, compatible lubricant. Insert self-sealing bolt through shipping plug and
into the eye of the impeller using a deep well socket. Insert a screwdriver into the motor fan to prevent motor shaft from rotating.
Securely tighten bolt using the torque specifications in the table below.
4. Remove the shipping plug from the suction port.
5. Rotate the motor fan by hand and check for impeller rubbing. If the impeller rubs, verify that the self-sealing bolt is properly
installed.
6. Proceed to the “Installation” section of these instructions.
