Checking The Cooling System - Omtech POLAR+ User Manual

4.4 Checking the Cooling System

The provided water pump is essential to your engraver's performance and
longevity. When this laser works without a properly maintained cooling system, its
glass tube WILL crack from excess heat.
NEVER adjust the water level within the tank while it and the laser are connected
to power.
1. Open the cover and confirm that the plastic tank to the right of your main bay is full.
The integrated water pump should arrive with about 1.5 L of OMTech coolant already in place.
This should not require replacement during the first year of service, but refill it if the tank ever
seems below two-thirds full before activation. For instructions, see
on Page 85.
2. Close the cover.
3. Plug in the interlock connector.
4. Confirm the power switch is in the O position before setting up the control system.
5. Plug the engraver into a grounded outlet or into a surge protector rated over 2000 J that is
itself connected to a grounded outlet. Use a dedicated circuit with no other devices on it.
Confirm that the voltage on the label above the laser's power socket matches your local power
supply.
Poor grounding WILL cause equipment failure and create a serious electrical
shock hazard. The manufacturer and/or seller bear(s) no responsibility and
assume(s) no liability for any damage, accidents, or injuries caused by bad
grounding connections.
6. Press the engraver's main power switch to I.
7. Insert and turn the laser key.
8. Confirm that the coolant begins to flow out of its tank, through the laser tube, and back into the tank.
If it does not work so, turn off the machine and contact our technical support team.
9. Turn the laser key back and unplug the engraver.
