Torch Coolant Draining
Hypertherm recommends draining the torch coolant from the power supply and torch before transporting the
system. After this draining procedure, a small amount of coolant will remain in the system pump and valves. For
this reason, Hypertherm also recommends that a suitable ratio of propylene glycol be purged through the system
prior to draining if the system will experience extremely cold temperatures. Note that Hypertherm's stock propylene
glycol solution 028872 is rated to 10° F (-12° C).
1. Disconnect all power to the system.
2. Remove the fill inlet cap from the reservoir to allow proper venting.
