1. Introduction and Overview
The Alphacool ES Distro Plate C1 is designed to streamline water cooling loops in server systems. It provides multiple connection points for components, facilitating a clean and organized setup, especially in confined server rack environments. This manifold helps manage tubing runs, ensuring optimal flow and simplifying component exchange within your water cooling system.
Important Note: This Distro Plate is not compatible with Alphacool ES Quick Release BLH1A Push-In Fittings.

2. Safety Information
Please read and understand all safety instructions before installing or operating the Alphacool ANKES Distro Plate C1. Failure to follow these instructions may result in property damage or injury.
- Always disconnect power from your system before performing any installation, maintenance, or modifications to the water cooling loop.
- Ensure all fittings are securely tightened to prevent leaks. Leaks can cause damage to electronic components.
- Use only compatible coolants and components designed for water cooling systems. Incompatible materials can lead to corrosion or system failure.
- Avoid over-tightening fittings, as this can damage threads or O-rings.
- Keep the product away from children and pets.

4. Setup and Installation
The Alphacool ES Distro Plate C1 is specifically designed for integration into Alphacool server racks. Follow these steps for proper installation:
4.1 Mounting the Distro Plate
- Identify the desired mounting location within your Alphacool server rack. Alphacool offers special mounting brackets for this purpose in most server racks.
- The ES Distro Plate C1 is typically mounted using two screws. Secure the mounting plate to the desired location first, then attach the Distro Plate to the mounting plate using the provided screws and Allen key.
- Multiple C1 Distro Plates can be connected in series on the carrier for expanded loop configurations.
4.2 Connection Possibilities
The ES Distro Plate C1 features a total of 4 G1/4 connections with 5mm deep threads. Two connections are located at the front, and one connection thread is on each front side.
- Plan your water cooling loop carefully to determine the optimal routing for your tubing.
- Connect your water cooling components (e.g., CPU block, GPU block, radiator, pump) to the G1/4 ports on the Distro Plate using appropriate fittings.
- Ensure all fittings are tightened securely by hand, then use a tool for a final snug turn, being careful not to overtighten.
- When laying tubing, aim for the straightest possible runs. Avoid tight bends, as these can restrict flow and potentially lead to kinks.

5. Operating Instructions
Once the Alphacool ANKES Distro Plate C1 is installed and all components are connected, follow these steps to prepare your water cooling system for operation:
- Filling the Loop: Carefully fill your water cooling loop with a compatible coolant. Use a fill port on your reservoir or pump/reservoir combo.
- Bleeding Air: Operate your pump at a low speed initially to allow the coolant to circulate and displace air. Gently tilt your system to help trapped air bubbles move to the reservoir. Continue this process until most air bubbles are removed from the loop.
- Leak Testing: Before powering on your entire system, perform a leak test. It is highly recommended to use a dedicated leak tester or run the pump with only the power supply connected for several hours (e.g., 12-24 hours) to check for any leaks. Place paper towels under all fittings and components to easily spot any drips.
- Final Check: After confirming no leaks, top off the coolant in your reservoir if necessary. Ensure all cables are properly connected and secured before powering on your computer system.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your water cooling system and the Alphacool ANKES Distro Plate C1.
- Inspection: Periodically inspect all fittings, tubing, and the Distro Plate for any signs of wear, damage, or leaks. Check for discoloration or cloudiness in the coolant, which may indicate contamination.
- Coolant Replacement: Replace your coolant according to the manufacturer's recommendations, typically every 6-12 months. Drain the old coolant completely before refilling with fresh coolant.
- Cleaning: If sediment or buildup is observed within the Distro Plate or other components, it may be necessary to disassemble and clean them. Use only distilled water or specialized cleaning solutions for water cooling components.
- O-Ring Check: During maintenance, inspect O-rings for cracks or deformation. Replace any damaged O-rings to maintain a leak-free seal.
7. Troubleshooting
This section provides solutions to common issues you might encounter with your Alphacool ANKES Distro Plate C1.
- Leaks:
- Symptom: Coolant dripping from fittings or components.
- Solution: Check all G1/4 connections for proper tightening. Ensure O-rings are correctly seated and not damaged. If O-rings get stuck inside a port, carefully remove and reseat them. Replace any worn or damaged O-rings.
- Restricted Flow / Poor Cooling Performance:
- Symptom: High component temperatures, weak coolant flow, or unusual pump noise.
- Solution: Verify tubing runs are not excessively bent or kinked. Ensure all components in the loop are clear of obstructions. Check for any blockages within the Distro Plate or other components. Ensure the pump is operating correctly and the loop is properly filled and bled of air.
- Air Bubbles Persist:
- Symptom: Continuous air bubbles in the loop despite bleeding efforts.
- Solution: Ensure the reservoir is adequately filled. Gently tilt the system in different directions to help dislodge trapped air. Run the pump at varying speeds. If bubbles persist, check for small leaks that might be drawing air into the system.
