To determine which option is NOT an application of Pascal's principle, we need to analyze each choice based on the principle itself, which states that a change in pressure applied to an enclosed fluid is transmitted undiminished to every point of the fluid and the walls of its container.

1. **Manual car lift**: This device uses hydraulic fluid to lift cars, transferring pressure through a fluid.
2. **Bicycle brakes**: Bicycle brakes often operate using hydraulic systems, where pressure is applied to the brake fluid, which in turn applies force to the brakes on the wheels.
3. **Electric fan**: An electric fan operates using electric motors to turn blades; it does not involve fluid pressure and Pascal's principle.
4. **Car brakes**: Similar to bicycle brakes, many car braking systems use hydraulic pressure to transmit force to the brake pads.
5. **Blood pumped by the heart**: The heart pumps blood through the circulatory system using pressure, fitting the definition of Pascal’s principle.

### Final Answer
The option that is NOT an application of Pascal's principle is **An electric fan**.
