2. Safety Information
- Fluid Compatibility: Use only clear, transparent water cooling fluids. Fluids containing particles or additives (e.g., Pastel fluids) can clog and permanently damage water cooling components such as radiators, pumps, and blocks. Use of such fluids may void the manufacturer's warranty.
- Impeller Handling: Removing the impeller from the ceramic shaft will cause the upper ceramic clamping ring to over-expand, leading to its destruction. This action will void the pump's warranty. If the pump is reassembled after such removal, the clamping ring will loosen, which is not accepted as grounds for return or exchange.
- Voltage: Ensure the power supply voltage is within the permitted range of 8-13V DC.
- Temperature: Do not exceed the maximum system temperature of 65°C.
3. Package Contents
The following items are included in the scope of delivery:

4.3 Electrical Connections
Connect the pump to your power supply and motherboard using the provided cables:
- 4-pin Molex: For main power supply to the pump.
- 3-pin Tach Signal: Connect to a motherboard fan header to monitor pump RPM.
- 4-pin PWM Signal: Connect to a motherboard PWM fan header for speed control.

5. Operating Instructions
The Alphacool Eispumpe VPP755 features an adjustable speed setting, allowing you to optimize performance and noise levels for your specific cooling needs.
5.1 Adjustable Levels
The pump can be adjusted in five distinct levels, controlling the rotational speed (RPM):
- Level 1: 1800 RPM
- Level 2: 2500 RPM
- Level 3: 3200 RPM
- Level 4: 3900 RPM
- Level 5: 4500 RPM
Adjust the level according to your system's cooling requirements and desired noise profile. Higher levels provide greater flow rate and pressure.
6. Maintenance
Regular maintenance is crucial for the longevity and performance of your water cooling system. Ensure to use only clear, transparent water cooling fluids. Avoid fluids with particles or additives, as they can cause blockages and damage to the pump and other components. Periodically inspect your loop for any signs of debris or fluid discoloration.
7. Troubleshooting
If you experience issues with your pump, consider the following:
- No Power/No Operation: Check all electrical connections (4-pin Molex, 3-pin tach, 4-pin PWM) to ensure they are securely seated and receiving power. Verify your power supply is functioning correctly.
- Reduced Flow/Noise: This could indicate air in the loop or a blockage. Bleed the system thoroughly to remove air. If using non-compatible fluids, a blockage may have occurred.
- Impeller Issues: As stated in the safety information, do not attempt to remove the impeller from the ceramic shaft. Doing so will damage the clamping ring and void the warranty. If the pump exhibits unusual noises or performance issues after unauthorized disassembly, it is likely damaged beyond repair and not covered by warranty.
