LYING DOWN (HORIZONTAL):

Carefully add 2 gallons (7.6 liters) of coolant through a funnel into the coolant reservoir fill hole.

AVOID SPILLING COOLANT INTO THE LOUVERS ON THE TOP OF THE COOLER.

The cooler is "FULL" when the coolant lies just below the coolant reservoir opening with the cooler in the upright (vertical) position.

NOTE: DO NOT ADD MORE THAN 2 GALLONS (7.6 LITERS) OF COOLANT INTO THE RESER- VOIR. The fill cap contains a pressure release air hole, which must not be blocked by overfilling the reservoir with coolant.

Be certain to replace the reservoir fill cap when the reservoir is full. Simply press on the inside center of the fill cap until the cap snaps into place. Operation of the COOL ARC® 40 without the fill cap in place can cause poor cooling efficiency, evaporation loss of coolant and reduced product life.

COOLANT "IN" AND "OUT" CONNECTIONS

The fittings located on the back center of the COOL ARC® 40 are two female 5/8-18left-hand threaded fittings. (CGA Style) These mate with water hoses typically used in the welding industry.

Refer to Figure 1.

Water or Coolant Line Connections to the

COOL ARC® 40

Take the connector nut of the water hose and check if the thread of the male connector nut matches the 5/8- 18 left hand female thread in the fitting on the back of the unit.

For all Lincoln products and those with a connector nut on the water hose that mate with the fittings on the back of the COOL ARC® 40:

(Reference FIG. 1) Take the accessory "INLET" hose (colored or tagged blue on most hoses) and thread it into the coolant "OUT" fitting located on the right side of the back of the cooler. 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 thread it into the coolant "IN" fitting located on the left side of the back of the cooler. Again, tightly secure the connector nut of the hose into the fitting of the cooler 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.

If the connector nut on a water hose does not mate with the fittings on the back of the COOL ARC® 40, order the following:
