If placing cooling unit on welding
power source, slots are provided in
bottom of unit so it fits over lift-eye.
To prevent overheating, make sure
cooling unit is positioned so airflow
is not restricted.
Y If welding power source has
a water valve, do not connect
hoses to water valve. Con-
nect hoses as shown.
Operation:
Turn power switch On. Flow indica-
tor spins to indicate that at least
