The LCD screen is at the highest level of the entire liquid cooling system. After the first few prints, the coolant heats up and may cause deformation of LCD screen. If deformation is takes place, please use the pressure release cap on the coolant tank to rebalance the pressure.

1. Put the printer on table and open the cover

2. Check if the pressure is normal in the screen cooling system

If there is no gap between the ruler and the screen, it is NOT necessary to release the pressure.

If there is gap between the ruler and the screen, it is necessary to release the pressure.

3. Put the printer sideways

Lay protections to prevent possible damage to the printer

4. Remove the ties and push out the coolant tank

5. Take off the coolant tank

Take off the coolant tank from the holder

6. Remove the joint of the coolant tank to release the pressure

Prepare some tissue to wipe off the coolant which may spill out of the tank; do not keep any electronic device near the printer

7. Squeeze the tube and tighten the joint

Tighten with suitable strength

Wipe clean the coolant tank and the tubes

8. Put back the coolant tank to the holder

Press tight the holder as the arrows show in the picture; make sure they are centered and match each other effectively

9. Put back the nylon ties

Fixate the holder with nylon ties

10. Put the printer upright

11. The pressure in the screen cooling system has been normal

Test with feeler gauge and there is no gap

12. Finished
