beamo II - Cooling Radiator Replacement Guide

Tools

Step 1

Turn off the machine, and remove the power cord.

Step 2

Remove the back metal cover.

Step 3

Step 4

Remove the laser tube's holders.

Step 5

Disconnect the grounding cable of the laser tube.

Step 6

Place the rags underneath the laser tube on both sides.

Step 7

Remove the water hose clamp from the high-pressure side.
Make sure the water hose plug is ready so it can be inserted immediately after the hose is detached.

Step 8

Remove the water hose clamp from the low-pressure side.
Make sure the water hose plug is ready so it can be inserted immediately after the hose is detached.

Step 9

Prepare a bucket in advance to drain the water from the laser tube.
The laser tube can then be removed, and the water will be drained.

Step 10

Remove the front metal cover. (T8 torx screw * 10 pcs.)

Step 11

Unplug the cables on the laser PSU.

Step 12

Remove the four screws on the laser power supply.

Step 13

Remove the laser PSU and place it aside temporarily. 
(Please pull out the PSU cable to create more working space.)

Step 14

• Unmount the water pump from the frame of the machine.

• Remove the cable of the water pump from the mainboard.

Step 15

Remove the cable of the water pump from the mainboard.

Step 16

Place the rags all around the mainboard and the wires inside the machine.
Please refer to the video.

Step 17

Remove the metal clips on the water hoses.

Step 18

Detach the water pump from the water hoses, then remove the water pump from the system.
Please prepare the hose plugs in advance, as water is likely to leak when the pump is detached. We suggest using the plugs at once.
(Use the paper towel to prevent the water hose from being damaged by the pliers.)

Step 19

Drain the water from the pump and set it aside for later.

Step 20

Disconnect both cooling fan cables from the mainboard.

Step 21

If any cable ties secure the fan cables, cut and remove them.

Step 22

Remove the four Phillips screws securing the left cooling fan (the fan closest to the mainboard), then remove the fan. The ground wire is secured by one of these screws.

Step 23

Remove the four Phillips screws securing the right cooling fan (the fan closest to the laser tube), then remove the fan.

Step 24

Remove the screws of the cooling radiator at the bottom of the machine.
(T8 screws x 6 pcs)

Step 25

Remove the cooling radiator from the machine.

Step 26

Remove the water hoses from the radiator. You can skip this step if you have new water hoses to replace.

Step 27

Connect the water hoses to the new radiator. Make sure the water hoses connect to the same positions as in the video.

Step 28

Place the radiator in position. Make sure no wires or cables are underneath the radiator.

Step 29

Fix the radiator by screwing in the bottom screws. (T8 screws x 6pcs)

Step 30

Reinstall the right cooling fan and secure it with the four Phillips screws. Make sure the cable-routing opening on the fan is oriented the same way as on the original fan.
(On your side, the water pump and the laser tube are still removed at this moment.)

Step 31

Reinstall the left cooling fan and secure it with the four Phillips screws. Reattach the ground wire using the same mounting screw that originally secured it.
(On your side, the water pump and the laser tube are still removed at this moment.)

Step 32

Reconnect both cooling fan cables to the two cooling fan connectors on the mainboard.

Step 33

• Connect the water hoses to the new water pump.

• If you find the water hose is bent as in the video, please try to twist the water hose to make it unbent.

Step 34

• Remove the rags and screw the water pump onto the frame.

• Connect the pump cable to the mainboard.

Step 35

Place the laser PSU in its position.

Step 36

Fix the PSU with the four screws.

Step 37

Plug the cables into the laser PSU.

Step 38

Place the laser tube on the machine and connect the grounding cable to the terminal.
(The grounding cable has to be on the same side as the other one.)

Step 39

From the high-pressure side, remove the hose plug and connect the water hose to the laser tube.

Step 40

From the low-pressure side, remove the hose plug and connect the water hose to the laser tube.

Step 41

Fix the laser tube in place. Please note these two points:

1. The distance between the laser tube's nozzle and the first mirror seat will be around 1.5cm (one finger).
2. There are two short water hoses on both sides of the laser tube; they have to be horizontal.

Step 42

Place the foam back and connect the cables between the laser tube and the laser PSU.

Step 43

Install the front metal cover. Ensure the Type-C cable's white dot faces up, as shown in the video.

Step 44

Add water to the system.
