English
Reserator 1 is designed with an optimal heat dissipation area based on Zalman
Tech’s HCET (High Capacity Extrusion Technique) and high efficiency cooling
technology. As a result, this product achieves excellent cooling performance
even with natural convection, making it the world’s first fanless, noiseless watercooling system. The reservoir, radiator, and the water pump are conveniently
integrated into one assembly, and the heatsink is anodized to prevent corrosion
and rust. In addition, the kit includes the high-performance ZM-WB2 Gold water
block which is not susceptible to galvanic corrosion.

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-WB2 Gold)
The system includes Zalman’s new CPU cooling component,
ZM-WB2 Gold, which performs superbly and installs easily.
1.3 Flow Indicator
This component is connected in-line with the circulation tube to
check 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.

5. Installation
5.1 Determine the Placement of the Reserator 1
The reserator’s placement should be determined with regard to the connected 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.
5.2 Install the CPU Water Block (ZM-WB2 Gold)
1) Refer to the manual included with ZM-WB2 Gold on how to install.
2) ZM-WB2 Gold can be installed on Socket 478, 462, 754, and 940.
3) If a water block from another manufacturer is to be installed, refer to the manual included
with that product on how to install.
4) If interference occurs while installing, stop the installation.
5) Only 13 x 10 mm or 12 x 8 mm silicone tubes can be used with this product.

5.4 Fasten the Universal Fitting
If you want to drill the holes in the
side of the case for fastening, each
of them should be 16 mm in diameter.
The tube holes should be made at
the same height as the slot holes at
the back of the case.
Universal Fitting
Fitting Nut
Fitting Cap
If the universal fitting is to be fastened on the PCI slot hole in the back of the case, separate
the fitting cap and the fitting nut from the universal fitting. Then, insert the universal fitting into
the PCI slot hole from the inside towards the outside as shown and fasten with fitting nuts.
ф16 Hole
Connecting Fitting and Silicone Tube - The Easy Way
1) Slide the Fitting Cap over the silicone tube
2) Push the silicone tube all the way inside the Fitting socket.
3) Screw on the Fitting Cap until it is completely fastened.
4) Pull the silicone tube slightly with your hands to see if it is loose. Cut about 100 mm
of the silicone tube and use it around the Fitting Cap to fasten the cap easily.
Be careful not to have the silicone tube fold or twist, as scratches and damage may
lead to leaks.

5.5 Connect the Reserator with the Universal Fitting
Using silicone tubes, connect the IN / OUT compressing fittings, the flow indicator, and the
universal fitting as shown above. The flow indicator is used to check the circulation of the
coolant, so it should be placed where it is easily visible.
Note) The flow indicator must be installed in the direction shown.

5.6 Confirm Correct Installation
5.7 Add Coolant
1) Check that the placement of the product confirms to section 5.1.
2) Confirm that the coolant circulation path is correct, as shown below.
3) Lightly tug the silicone tube connected to each of the Compression Fittings and the
Universal Fitting to check for loose ends.
1) Take off the Reserator’s cover.
2)
Fill the Reserator to 80~90% of its height.
Distilled water is recommended, but
tap water can be used instead.
Reserator 1’s maximum capacity is 2.5
liters. When adding the coolant, make
sure that no contaminant is introduced.

5.8 Leakage Inspection and Test Run
1) Turn off the PC’s power completely before starting
leakage inspection.
2) Confirm that the coolant is adequately filled.
It should be filled to about 80~90% of the Reserator’s
capacity.
3) Check each fitting for leaks. If there is a leak,
circuitry and other components may short circuit
and malfunction, so be careful.
4) Only if there is no leak in any of the fittings and the
Fitting Sockets, turn on the water pump. If the
coolant does not circulate properly, turn the pump
on and off repeatedly to eliminate air bubbles.
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
vibrates 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.
Coolant refers to a circulating fluid that absorbs heat from heat sources such as a CPU
and a GPU, and dissipates it at the radiator. Typically recommended coolant used in a
water cooling system is distilled water, but tap water can also be used. To prevent
galvanic corrosion, special coolants such as antifreeze are sometimes used.
(Zalman’s ZM-WB2 Gold is gold-plated, so galvanic corrosion does not occur.)

7) Remove the integrated water pump pull the water pump off the sink base
as shown.
8)Put on the Sealing Bolt B - after
removing the cable fitting, screw on
the Sealing Bolt B. Fasten until tight. If
this is not done properly it may cause
leakage.
9)Reassemble the sink base - after all
the steps are taken, reattach the sink
base to the main body firmly. Take
proper care in doing this as leakage
may result if not done correctly.

6.2 Install the External Water Pump
6.3 Cautions on Choosing and Installing an External Water Pump
After determining the placement of the external water pump, check the components that create
a path as shown above. It is recommended that the installation is done in such a manner.
1) When installing an external water pump, confirm the coolant entrance and
exit holes before connection.
2) Check that the chosen water pump’s holes are compatible with the provided silicone tube.
3) Zalman Tech is not responsible for performance degradation or malfunction of a
system that arises from using an external water pump.

Separate the Reserator and Water Block
When moving this product to another location, or replacing the coolant or the water block,
separate the Reserator and the water block from the silicone tubes as shown below.
7.1 Moving the Reserator or Changing the Coolant
1) Turn off the PC’s power.
2) Using the tube clamps, as shown
in the diagram, insert the tubes in
to both sides of the Universal Fitting.
If the press clip isn’t properly tightened,
there may be leaks, so make sure
that the silicone tube is placed in
the middle of the clamp.
3) Turn clamp screw until it is tight.
4)Unscrew the Universal Fitting
Caps on the outside of the case
one by one. If you unscrew the
Fitting Socket Caps inside the
case, residual coolant may spill into
the case.

3) To let the residual coolant flow back
to the Reserator, place the CPU
water block higher than the coolant
level of the Reserator.
4) Fasten the Clamp on the entrance
and the exit tubes of the CPU water
block.
5) Unscrew the Fitting Caps from the
CPU water block. Residual coolant
inside the tube and the water block
may flow out, so clean up using a
paper towel or a piece of cloth.

8. FAQ
8.1 When the Coolant isn’t Circulating
(1) Check that the water pump is connected to the power.
(2) Verify that the pump is properly functioning. Remove the Reserator’s sink cover and
look inside to see if there is movement in the coolant. If there is none, contact the
distributor where you purchased the product.
(3) Make sure that the Reserator is installed correctly. It must be placed at the same level
as the PC, or slightly higher.
(4) Check if the coolant is flowing in the right direction.
(5) Inspect for any twists or folds in the silicone tubes of the system.
(6) Durning initial operation, the coolant may not properly circulate due to internal air
pressure. In this case, repeatedly turn the water pump on and off at a 10-second
interval and shake the silicone tubes to help get the air bubbles out. Once they are out
of the system the coolant should be circulating properly.
8.2 When There is a Leak at a Compression Fitting or Universal
Fitting Socket
(1) Turn off the system.
(2) Make sure the silicone tube is pushed all the way into the end of the Fitting Socket.
(3) Check to see that the tube is cut cleanly and squarely.
(4) Verify that the Fitting Cap has been screwed all the way into the end of the fitting Socket.
