MCP350 or MCP355 pump installation – skip this step if you have the MCR Drive with integrated pump version

Disassemble the MCP350 or MCP355 pump ports housing from the
main motor housing by loosening and removing all 4 screws. Reassemble the
pump body to the MCR drive radiator while making absolutely sure to keep
the existing pump o-ring in place or the assembly will leak! To assemble,
simply align the pump body with the MCR Drive pump housing, and fasten it
with the supplied 8-32 x ¾” socket screws.

MCR220 and 320 Drive installation

1. Installation of the fittings:

The MCR Drive heat exchangers are shipped with 2 sets of fittings: ½”

(12mm) and 3/8” (10mm). Each set is composed of two different fittings: a

long fitting that screws into the radiator inlet identified by an “IN” label, and a
short fitting that screws into the pump housing outlet identified by an “OUT”
label. Use a 5/8” (16mm) flat wrench or preferably a socket wrench to fasten
the fittings very tight to the radiator body so as to prevent leaks.

2. Installation orientation considerations and guidelines

The primary consideration in the notes below is safety. Because this type of
pump is not self-priming, it is essential to configure the liquid cooling system
so that it remains self-purging, in other words, that any air travelling through
the lines could never accumulate in the pump, thus causing coolant circulation
to stall.

In its default configuration, in other words vertical and right-side up, the MCR
Drive pump can never lose its prime unless the coolant level was abnormally
low. Therefore, as in any other “open-loop” liquid cooling system it is
essential to monitor the coolant level every few months by simply checking the
reservoir fill-cap gauge.

Alternate orientations to the factory default are discussed below, and may
require an additional reservoir to safely operate the MCR Drive.

(*1): Vertical upside-down orientation, typical of an installation behind the front
bezel, or at the back of the PC. This orientation would require an external
reservoir; however, it is not recommended because depending on the
reservoir location there is a risk for the pump of losing its prime if a sufficient
amount of air was to travel through the lines: this could result in catastrophic
failure of the cooling system. Additionally, it is not recommended to run the
pump upside-down.

(*2): Horizontal & flat face-up orientation, typical of an installation at the
bottom the PC. This configuration necessitates the use of an external
reservoir but is fully acceptable as long as that such reservoir will always be
located higher than the radiator.

(*3): Horizontal & flat face-down orientation, typical of an installation on the
upper panel of the PC. This orientation would require an external reservoir;
however, it is not recommended because depending on the reservoir location
there is a risk for the pump of losing its prime if a sufficient amount of air was
to travel through the lines: this could result in catastrophic failure of the
cooling system. Such orientation is ONLY acceptable if an external reservoir
was located above the pump, but this is typically impossible since the radiator
is already located at the highest point of the PC.

(*4): Side orientation and fill-port facing up, typical of an installation in a lower
compartment of the PC. When used in this orientation the radiator integrated
reservoir will only be fully functional if completely filled-up. Furthermore as the
coolant level drops over time, the uppermost radiator channel(s) may not
circulate fluid, resulting in cooling performance degradation. Use of an
external reservoir located above the radiator is recommended to avoid this
risk.

(*5): Side orientation and fill-port facing down, typical of an installation in a
lower compartment of the PC. This orientation would require an external
reservoir; however, it is not recommended because depending on the
reservoir location there is a risk for the pump of losing its prime if a sufficient
amount of air was to travel through the lines: this could result in catastrophic
failure of the cooling system. Such orientation is ONLY acceptable if an
external reservoir was located completely above the radiator.

Advanced/Extreme applications:

It is also possible to install two MCR Drive in series. In such case it is
recommended to install one of the units in the factory recommended default
orientation; this will allow installation of the second unit in ANY orientation,
including the orientations listed above as not recommended. The reason is
that the primary unit in default orientation will naturally and safely purge any
air going thru the lines, thus eliminating any risk that the second pump might
stall.

3. Installation of the fans and to a panel:

See schematic to the right.
The 2 conventional methods to attach the fans and the assembly to a panel

are:
Either: using the provided four M3.5 short screws (1) per fan to fasten the

lower lip of the fans to the radiator body, and then another fastener of your
choice (not provided) to secure the assembly to the computer panel (3).
Standard fan screws often provided with the fans work well to attach the
assembly to the panel.

Acceptable replacement short screws types are: either US 6-32, or M3,5.
Screw length specifications are: Min: 1/4” (6mm) - Max: 5/16“ (8mm)

Or: using the provided four long screws (2) per fan thru the computer panel
(3) and thru the fans to fasten the entire assembly to the panel.

Acceptable replacement long screws types are: either US 6-32, or the
supplied M3,5.
Screw length specifications are:

- inch Min/Max: 1 1/8” (30mm) this is the only adequate size available in this
size range for 120x25mm fans. Use 6-32x1 5/8” or M3,5 x 40mm for
120x38mm fans.

WARNING: do not exceed the maximum recommended screw length or
irreversible damage to the radiator will occur, not covered under your
warranty.

You are now ready to connect tubing to the MCR Drive inlet and outlet fittings,
using the provided hose clamps, and to complete the loop by a waterblock of
your choice.

4. Electrical connections, pump general operations, specifications, warranty

a/ Electrical installation:
The pump uses two connectors: a standard Molex 4-pin (2 wires are used only) which connects to the PSU connectors, and a standard 3-pin
(single wire) which connects to a 3 pin motherboard header, and allows the motherboard to read the pump rotational speed (RPM). This is merely
a sensor, and it does not allow speed adjustments.

b/ Operating precautions:

The MCP350 pump should never be run dry, even for a quick test. You should always prime the pump by filling-up the MCR Drive radiator with

fluid before you start operating it (see warranty note *).

Use of coloring die or fluorescent additives containing particulate fillers will cause excessive wear to the pump’s impeller bearing (see warranty

note **).
