Chiller cleaning
The chiller is composed of components (condenser block...) that must be checked for blockage with dirt or other foreign
bodies. Since air is sucked in via the side panels, dirt tends to accumulate on the inside of the blocks. The chiller must be
cleaned as follow:
Caution: wear PPE (disposable rubber gloves, anti-static coverall, FFP3 respiratory protection, anti-static
safety shoes) .
Procedure:
1.
If the printer is already switched off, then proceed to next step. If not, switch off the printer (see section "Shutting
printer down" on page 69).
2.
Switch off the 2 UPS (see "E. Control/supply cabinet" on page 28).
3.
Lock out and tag out the printer: position the main switch from the supply cabinet to position "O", then put a lock with a
tag out label on the switch. This will disconnect and isolate the printer from energy during the maintenance.
4.
Split-up the control/supply cabinet from the main cabinet (the maintenance requires access to the sides of the control/
supply cabinet).
As the fiber laser is still connected to the main cabinet, move the supply cabinet gently. Do not damage
any cables .
5.
Open the right door of the control/supply cabinet.
6.
At the rear of the chiller, remove the following cable:
•
Power cable (1),
•
Signal cable (9pin SUB D, M) (2)
•
Coolant water pipes (3+4).
Water leakage hazard . Use of cotton cloth and tank recommended (to recover liquid and to clean) .
7.
Remove the 2 screws located inside the air ducting hose (5).
Make sure not to drop screws and washers during
removal .
8.
Open the left door of the control/supply cabinet.
9.
Remove the chiller by removing the screws located in front of the chiller (6).
Use a lifting trolley when removing the chiller .
