The LN-7 or LN-7 GMA must have a K527 Water

solenoid installed. Refer to Figure A.19 and perform
the following steps:
NOTE: If not using a Lincoln water cooler , and if your
water cooling device is not designed for use with a
waterline solenoid valve, you may remove the solenoid
and screw the male fitting (after applying sealant)
directly into the brass manifold block.
1. Using male 5/8-18 UNF left-hand thread fittings,
connect appropriate water hoses to the coolant
inlet and outlet on the back of the LN-7. Connect
the other ends of these hoses to the appropriate
ports on your water cooling units.
2. In the event the water line fittings on your water
cooled gun are incompatible with the female quick
connects on the front of the LN-7, male quick
connects are provided for installation on 3/16 in.
