Lincoln Electric IM10117 COOL ARC 55 WATER COOLER - Manual (Page 10)

A-4 INSTALLATION
COOL ARC ® 55

COOLANT "IN" AND "OUT" CONNECTIONS
The fittings located on the COOL ARC ® 55 are two
female Quick Disconnect fittings. These mate with
water hoses typically used in the welding industry.
Two couplers converting from quick disconnect to 5/8-
18 left-hand thread (CGA style) are also included.
Refer to Figure A.2.
Water or Coolant Line Connections
to the COOL ARC
® 55
Take the male quick disconnect of the water hose and
check if it matches the coupler or the quick disconnect
on the front of the unit. When using water hoses with
threaded nuts use the supplied couplers to convert
from 5/8-18 left hand female thread to male quick dis-
connect.
(Reference FIG. A.2) Take the accessory "INLET"
hose (colored or tagged blue on most hoses) and plug
it into the coolant "OUT" fitting located on the front of
the cooler. If necessary use the supplied coupler,
making sure to secure the connector nut of the hose
tightly into the fitting with a wrench so that leaking
does not occur. Then take the accessory "OUTLET"
hose (colored or tagged red on most hoses) and plug
it into the coolant "IN" fitting located on the front of the
cooler. Again, if necessary use the coupler, tightly
securing the connector nut of the hose into the fitting
with a wrench to insure that no leaking occurs.
NOTE: BE CERTAIN THAT NO LEAKS EXIST
WHEN THE COOLER IS TURNED ON. A LEAK
WILL DEPLETE RESERVOIR VOLUME, CAUSING
POOR COOLING PERFORMANCE AND REDUCING
GUN OR TORCH LIFE.
