It is advised to vacuum the chiller every month to keep the printer in the best condition. Vacuuming the chiller is part of periodic maintenance so the operator panel gives a warning when you should vacuum the chiller. Always check the fluid level when you vacuum the chiller.
Use Colorado M-series prescribed:
Screwdriver (Torx-25)
Vacuum cleaner with a brush head
To check the fluid level, locate the level gauge glass behind the right-hand side of the cover.
Do not remove this section of the cover. You can see the level gauge glass through the openings in the cover.
If the fluid level is near the bottom of the green zone, you must refill the chiller.
Do not remove any parts of the chiller.
Vacuum the surface with care, make sure you do not damage the condenser surface.
