100i / 200i / 300i / 400i
Manual PN: 0560956430 INSTALLATION 65
Included with the External Cooler are two 10’ hoses, supply (green) and return (red), that are to be connected to the matching
colors on left side of the External Cooler and to the supply and return fittings on the rear of the 400i power supply. Hoses to the
Remote Arc Starter connect on the right side of the External Cooler.
CAUTION
Do NOT cross the coolant lines as this will not provide cooling for the plasma torch as designed
and void the warranty.
Attach and tighten all #6 JIC fittings with 11/16” (18mm) wrench. Do not overtighten as it will strip the fitting threads and will cause
a leak. Do not start the 400i without coolant in the reservoir. An additional gallon (3.78L) of coolant is required to compensate for
the External Cooler being attached to the system. Monitor the fluid level while filling the iSeries power supply. Do not allow the
coolant reservoir level to drop below minimum.
Attach the cable from J70 on the power supply to J71 on the Heat Exchanger after the Cooler and coolant lines have been deter-
mined to be leak free.
