◆ Models CIMR-P7U2022 thru 2110 (30HP to 150HP @ 208V/240V) and 4024 thru 4300
(40HP to 500HP @ 480V)
A cooling fan assembly is attached to the top inside the iQpump drive. The cooling fan assembly includes the heat sink cooling fans and
the internal cooling fan. The cooling fan(s) can be replaced without removing the iQpump drive from the enclosure panel.
■ Removing the Cooling Fan Assembly
1. Always turn OFF the input power before removing and installing the heatsink cooling fan assembly.
2. Remove the terminal cover, iQpump drive cover, Digital Operator, and front cover from the front of the iQpump drive.
3. Remove the Control PCB bracket (if necessary) to which the cards are mounted. Remove all cables connected to the Control PCB and
remove the cooling fan power connector from the fan board (13 PCB) positioned near the top of the iQpump drive.
4. Remove the cooling fan power connectors from the gate drive board (3PCB) positioned at the back of the iQpump drive.
5. Remove the fan assembly screws and pull out the fan assembly from the iQpump drive.
6. Remove the cooling fan(s) from the fan assembly.
■ Mounting the Cooling Fan Assembly
After attaching a new cooling fan, reverse the above procedure to attach all of the components.
When attaching the cooling fan to the mounting bracket, be sure that the air flow goes toward the top of the iQpump drive.
