Installation and Operational Notes
Installation Notes
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 and sink cover.)
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 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 block(s) before the installation.
Operational Notes
1. Use a power strip with a power switch, and connect both PC and Reserator 1 Plus to
the power strip to allow simultaneous power ON/OFF switching.
2. Always turn on the water pump first before using the system.
3. If the coolant isn’t circulating or the pump is making a strange noise, turn the PC OFF

1. Features
The Reserator 1 Plus 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 1 Plus is a fanless water cooling system that unites the functions of a
reservoir, radiator, and water pump into one system for easy operation. It is anodized
and comes with a custom coolant to prevent corrosion. The new CPU Water Block
(ZM-WB3 Gold), VGA Water Block(ZM-GWB2), and the optional Northbridge Water
Block(ZM-NWB1) enable the setup of a complete Water Cooling System with excellent
performance. 3
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.
1. 2 CPU Water Block (ZM-WB3 Gold)
The CPU Water Block incorporates a pure copper base for excellent
heat transfer, and has gold plating to prevent corrosion. It supports
Pentium 4 Socket 775/478 CPU & AMD Socket 462/754/939/940
CPU, and is designed to be lightweight and easy to install.
1. 3 VGA Water Block (ZM-GWB2)
The VGA Water Block incorporates a light weight pure aluminum
base for high cooling performance, and is anodized and coated to
prevent corrosion. RAM heatsinks are included for a complete video
card cooling solution. The VGA Water Block can be installed on
graphics cards with heatsink mounting holes.
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 Anti-Corrosion Coolant (ZM-G100)
This coolant contains a high quality anti-corrosion agent for various
materials including copper, aluminum, and plastic, that prevents
corrosion for long term operation.
1. 6 Flow Indicator
This component is connected in-line with the circulation tube for
checking the circulation of the coolant. When the coolant is actively
circulating, the cap inside the flow indicator shakes rapidly, providing
easy indication of the circulation status.
1. 7 Quick Coupling
The Fittings incorporate valves that prevent leaks when
disconnecting the Silicone Tubes allowing quick, convenient
separation and reassembly of the Reserator for transport and coolant
replacement .

Northbridge Water Block (ZM-NWB1)
This anodized, pure aluminum block is built for high
performance cooling, and is designed for board
compatibility with a wide variety of northbridge chipsets.
Power Supply
By implementing heat-sensor circuitry that controls the
fan’s speed in relation to the temperature within the
power supply, noise is significantly reduced, making this
component suitable for noiseless systems.
Heatpipe HDD Cooler
This component cools the heat generated from the hard
disk drive and reduces the vibration that is passed onto
the computer’s enclosure.
Silicone Tube
If the standard silicone tube is found to be short or you
need to use the tube on another system, additional
tubes can be purchased separately (4m, 12 x 8 mm).
5. Installation Guide
Before installing the product on a PC, check each water block and the reserator for leaks.
5. 2 Determine the Placement of the Reserator
The reserator’s placement should be
determined in relation to the position
of the PC. Place it upright next to or
slightly above the PC. Note that if the
Reserator is placed lower than the PC,
the silicone tube’s internal air pressure
may prevent proper initial operation.

5. 11 Fill the Coolant
1) Take off the Sink Cover on top of the Reserator.
2) Fill with the provided coolant (ZM-G100) and two liters of distilled water.
Note 1) The provided coolant is a concentrate, and must be mixed down with distilled water
for operation.
Note 2) Read the warning label on the coolant before use.
Note 3) Keep this product and its associated system away from children.

5. 12 Leakage Inspection and Test Run
1) Turn off the PC’s power completely before starting leakage inspection.
2) Turn on the water pump. If the coolant does not circulate properly, turn the pump on and
off repeatedly to eliminate air bubbles.
3) Check each fitting for leaks. If there is a leak, circuitry and other components may short
circuit and malfunction, so be careful.
4) If there is a leak, turn the pump off immediately, wipe the area that leaked clean with a
paper towel, and reassemble the affected part.
5) While the pump is turned on, check the circulation status with the Flow Indicator.
If the coolant is circulating well, the cap inside the Flow Indicator will shake rapidly.
6) Leave on for an hour and check for leaks.
7) If there are no leaks, turn on the PC’s power and use the system. 13
