replacement (Video is available at Agilent.com).
To replace the pump module:
1
Disconnect the pump from electrical power and disconnect the power cord
from the power cord socket.
2
Stand the pump on the fan cowling (cover the work surface to protect the pump
finish).
3
Loosen the four M5 captive screws (item 1) that hold the motor cowling in
place (item 2), but do not remove the motor cowling.
4
Stand the pump on the motor cowling (cover the work surface to protect the
pump finish).
5
Remove the four M5 socket head screws (item 3) that secure the fan cowling
(item 4).
6
Remove the fan cowling, disconnect the electrical connector, and set the
cowling aside.

Remove the four M5 socket head screws (item 5) that secure the base plate
(item 6); remove the base plate, and set aside.

Lay the pump on its side and slide the motor cowling off the pump. Disconnect
the electrical connector and set the cowling aside.

Remove the four M6 button head screws (item 7) that secure the motor to the
pump module and set the motor aside.
10 Install the new coupling spider (item 8) to the coupling (motor side or pump
module side) and install the motor to the replacement pump module with the
label facing up (in the same direction as the inlet flange of the pump module).
Secure the motor with four M6 button head screws.
11 Reconnect the electrical connector on the motor cowling to the motor.
12 Tuck the electrical connector behind the aluminum plate mounted to the motor
cowling (item 9) and slide the motor cowling into place.
