7.3 Refilling the Water Tank
7 Maintenance
NEVER touch or adjust your engraver’s water supply while your engraver is
still connected to power.
Always fill the chiller with deionized or distilled water or a custom-purpose laser-
safe antifreeze. Using tap water for any purpose but rinsing out cleansers (see
§
7. 2.5 Cleaning the Water Chiller above) will gradually degrade the quality of
your engraver and may even cause dangerous mineral buildup within the cooling
system. Never use generic antifreeze for the same reason.
In addition to the regular cleaning above, check that the tank is at least two-thirds full of coolant or
clean water before and after each use.
If the tank ever begins to run low, use a funnel and tube to add more distilled water or laser-safe
coolant, or remove the right panel and add the fluid directly with a funnel (see
§
7. 2.5 Cleaning the
Water Chiller above).
