Warning!

• Disconnect the engraver from power before replacing the coolant.
• NEVER touch or adjust your laser’s water supply while it is still turned on or connected to power.

If the coolant becomes visibly contaminated, discontinue work and clean the tank and pipe as instructed below:

Tools Needed:

• Funnel
• Distilled water/laser-safe antifreeze

Step 1: Turn off and unplug the engraver.

Step 2: Access the drain port and remove the cap.

Step 3: Fully drain the old coolant.

Step 4: Remove the chiller fill port cap and fill the tank with laser-safe antifreeze or pure, distilled water until it reaches near the top of the green “NORMAL” range.

Step 5: Wait a couple of minutes and check the cooling liquid level in the chiller. If the level is below “NORMAL”, open the rear access door using the access keys to check the laser bay and bottom left access door for leakage.

Step 6: Once all tubes are checked, fill the tank with more antifreeze or distilled water until the level reaches the top of the green “NORMAL” range on the gauge.
