Please read this manual thoroughly before installation. The specifications of this product and its components may change without prior notice to improve the performance thereof.
The specifications of any product may change without prior notice to improve performance.
1. Make sure that the power source’s output voltage and frequency are compatible with the power input requirements of the water pump before installing (input voltage and frequency of the water pump are shown on the box).
2. Do not place in dusty or humid conditions, under direct sunlight, or near a heat source such as a room heater.
3. Do not drop or subject it to excessive force.
4. CPU socket compatibility must be checked.
5. Familiarize yourself with this manual.
6. Do not mix any contaminant with the coolant when filling, for it may cause product failure.
7. Check for leaks on Water Blocks before installation.
Installation Notes
1. Reserator 2 simultaneously operates with the PC. The power must first be supplied to the AC power cable before turning on the PC because it uses an AC pump.
2. Place the Reserator 2 and the PC body at the same location for use.
3. If the coolant isn’t circulating properly, or if the pump flux becomes too low, then the red blinkers will flash as well as warning sound. In this case, turn the PC OFF immediately.
4. Do not place any objects on the product.
5. Install on a flat surface with no vibration or slant, and do not tilt or lay horizontally.
6. Use distilled water with the coolant, regularly check the amount of coolant, and replenish as needed (must be replenished every year).
7. If a leak is found, turn off the system immediately, and contact the place of purchase or ZALMAN.
8. If the system will not be used for an extended period of time, then turn the Water Pump OFF.
9. When moving the system, separate the Reserator from the PC case before moving.
10. Do not let any air bubbles form inside the Water Block and the tubes during operation.
11. Always make sure that the Water Pump is functioning properly.
12. If the power supply cord is damaged, it must be replaced by the manufacturer, its service agent, or a similarly qualified person in order to avoid a hazard.

Installation and Operational Notes
The specifications of any product may change without prior notice to improve performance.
Reserator 2 incorporates Zalman’s HCET(High Capacity Extrusion Technique)
technology, high efficiency cooling technology, and optimal heat dissipation design for
exceptional cooling performance even through natural convection cooling.
The Reserator 2 is a noiseless and fanless water cooling system that incorporates a and
Flow Indicator in the front section, a high efficiency heatsink in the middle section, and a
water tank and water pump in the back section which allows easy installation and use.
The anodized product and the provided coolant prevents corrosion. The new CPU
Water Block (ZM-WB4 Gold), VGA Water Block (ZM-GWB3), and the optional
Northbridge Water Block (ZM-NWB1) and VGA RAM Water Block (ZM-RWB1) enable
the setup of a complete Water Cooling System.

1. 1 Reserator (Reservoir + Radiator + Water Pump)
“Reserator” is a compound word derived from ‘Reservoir’ and ‘Radiator’- it acts as a reservoir while radiating heat. This product works well with natural convection and integrates a Water Pump inside for convenience. It incorporates a flux observation/warning device as well as the Flow Indicator in the front, which further allows a safe and convenient use of the product.
1. 2 CPU Water Block (ZM-WB4 Gold)
The CPU Water Block incorporates a pure copper base for excellent heat transfer, and is gold plating to prevent corrosion. It supports Pentium 4 Socket 775/478 CPU and AMD Socket 754/939/940 CPU, and is designed to be light weight and easy to install.
1. 3 VGA Water Block (ZM-GWB3)
The VGA Water Block incorporates a light weight pure aluminum base for high cooling performance, and is anodized and coated to prevent corrosion. It also incorporates revolving fittings that provide freedom in direction when connecting them with the tubes, which further allows simple installation.
1. 4 Northbridge Water Block (ZM-NWB1, Optional)
This anodized, pure aluminum block is built for high performance cooling, and is designed for compatibility with a wide variety of Northbridge chipsets.
1. 5 VGA RAM Water Block (ZM-RWB1, Optional)
This anodized, pure aluminum RAM Water Block is built for high performance cooling, and is compatible with GeForce 7800/7900 and ATI X1800/X1900 in need of VGA RAM cooling. It provides easy installation.
1. 6 Anti-Corrosion Coolant (ZM-G300)
This coolant contains a high quality anti-corrosion agent for various materials including copper, aluminum, plastic, that prevents corrosion for long term operation.
1. 7 Flow Indicator
This component is connected with the circulation tube for checking the circulation of the coolant. When the coolant is actively circulating, its impeller rotates and the blue LED is brightly lit, providing easy indication of the circulation status.
1. 8 Quick Coupling
The Fittings incorporate valves that prevent leaks when disconnecting the PVC Tubes allowing quick, convenient separation and reassembly of the Reserator for transport and coolant replacement.
