How to fill the cutting system with coolant
1. Get the correct coolant mixture for your cutting system.

See Coolant requirements on page 49 to determine what percentage of
propylene glycol to add in the premixed Hypertherm coolant (028872).
2. Remove the cap from the reservoir fill
port inlet that is located on top of the
plasma power supply.
3. Look into the fill port inlet to see into
the coolant reservoir.
4. Pour the coolant into the reservoir
until the coolant level gets to the
base of the fill spout.

You can see the coolant level
from the fill port inlet as you
pour the coolant.
CAUTION
Never operate the cutting system if you get a low coolant level notice.
There is a risk of serious damage to the cutting system and to the coolant pump if you operate
the cutting system with no coolant or with low coolant.
If your coolant pump is damaged, it may need to be replaced.
Never use automotive antifreeze in place of Hypertherm coolant. Antifreeze contains chemicals
that damage the torch coolant system.
Always use purified water with 0.2% benzotriazole in the coolant mixture to prevent damage to
the pump, torch, and other components in the coolant system.
CAUTION
If you use the wrong coolant mixture, it can damage the cutting system. See Coolant
requirements on page 49.
