Swiftech H20 80 R3 - Manual (Page 16)

1. General Use
The MCP350™ pump is a magnetically
driven centrifugal pump featuring a 12 V
DC brushless motor. It requires no
maintenance when used with de-
mineralized water and the appropriate
anti-fungal additives. We recommend
using 5% Swiftech’s HydrX
 as an
additive. The pump is designed to be
connected to your computer power supply
using the standard Molex 4 pin
connectors.
Effective 1/24/05, the pump features a
second wire equipped with a 3-pin
connector designed to connect to a
motherboard fan header, and to report the
impeller rotational speed (RPM sensor).
The MCP350™ pump is not submersible.
2. Physical installation
Determine the best location for your
pump by observing how the tubing
will be routed to the rest of the circuit.
Sharp bends in the tubing should
always be avoided to prevent kinks,
which will reduce or completely
prevent flow of the cooling fluid.
In general, we recommend
installation of the pump at the bottom
of the chassis.
The base of the pump features a soft
neoprene pad coated with strong
adhesive material. Once an
appropriate location for the pump has
been determined, simply peel-off the
pad’s protective paper, and press the
pump against the chassis surface.
The surface should be clean, and
non greasy. Screws & grommets are
also provided for permanent
installation, and require drilling holes
in the chassis (see permanent
installation page 2).
3. Pump operating precautions:
The MCP350™ pump should never be
run dry, even for a quick test
. You
should always prime the pump with fluid
before you start operating it (see warranty
note *). With filled lines, turn the
inlet/outlets upward to ensure there is no
air bubble in the impeller.
Use of coloring die or fluorescent
additives
containing particulate fillers will
cause excessive wear to the pump’s
impeller bearing (see warranty note **).

Do not utilize small diameter or flow restrictive fittings in the pump inlet line. Minimum line inner diameter is 3/8”. An example would be
a reservoir with ¼” fittings. This may cause the pump impeller to cavitate, lose prime, stop pumping and damage the pump (see warranty note
***).
