NOTICE
INCORRECT COOLANT CAN DAMAGE THE CUTTING SYSTEM
Refer to Coolant requirements on page 57 for the correct type of coolant to use.
Calculations for total coolant volume estimates
Use these calculations to get an estimate for the total coolant volume necessary for your plasma cutting
system.
The capacity of the coolant reservoir for the plasma cutting system is 22.7 liters – 45 liters (6 U.S. gallons
– 12 U.S. gallons). A cutting system with long leads requires more coolant than a cutting system with
short leads.
For coolant installation steps, refer to Overview of cutting system coolant
on page 209.

Coolant replacement and its significance
Hypertherm recommends that you replace all of the coolant at least once every 6 months, as part of
routine preventive maintenance. More frequent replacement can be necessary because of environmental
conditions including but not limited to contaminants in your coolant or diagnostic codes that indicate
coolant problems.
Adding new coolant to the reservoir when the coolant level is low is not the same as replacing all of the
coolant. All of the coolant must be removed to flush the coolant system.
