Step 3

Snip off the cable tie on the air pump if there is any.

Step 4

Use a plier to disconnect the air hose on the air pump.

Step 5

Unplug the air pump's cable on the mainboard.
(If your mainboard differs from the photos below, please check the diagram to find the correct cable position.)

Step 6

• Unscrew these hex screws. Please hold the air pump while unscrewing.
  
  
  
• The air pump with a bracket can then be unmounted from sheet metal, but it can't be removed as there is another air hose to be disconnected at the bottom.
  Please place the air pump aside at the moment.
  

Step 7

• There is a connection at the bottom for the air hose.
  Use a plier to disconnect it.
• The air pump can then be removed completely from the machine.
  

Step 8

Remove the air hose on the air pump.

Step 9

Connect the air hose to the new air pump.

If you find it hard to do so, you can use the plier to enlarge the air hose.

Step 10

Place the air pump in the machine and connect the air hose at the bottom of the machine.

If the air hose is loose when connected, applying a cable tie is suggested.

• Put the cable tie on the hose first and leave the tie loose for now.
  
  
  
• Connect the air hose to the bottom with the tie.
  
  
  
• Pull the cable tie to make it tight.
  
  
  
• Snip off the tail.
