Proper Coolant Addition

FREEZCOOL is recommended coolant for COOL

ARC®50. For use above freezing: Tap, distilled, deionized,

mineral water. For use below freezing: water and pure

ethylene glycol mixture (10% glycol between at 0°C and

30% at -15°C).

WARNING

DO NOT USE PREPACKAGED WELDING INDUSTRY

COOLANTS. These coolants may contain oil-based

substances which attack the plastic components in the

pump of the COOL ARC®50 cooler and severely reduce

pump life. Once added to the cooler, the substances are

virtually impossible to purge from the water lines and heat

exchanger.

To avoid freeze damage and water leakage in shipment,

every COOL ARC®50 unit is delivered empty with no

coolant in the system. To fill the unit, locate the plastic

reservoir fill cap (B).

NOTE: The unit can be filled only horizontal.

WARNING

UNPLUG THE COOLER BEFORE FILLING THE

RESERVOIR.

Filling:

Pour 6 liters at least of coolant into the reservoir.

WARNING

AVOID SPILLING COOLANT INTO THE FRONT

CASING OF THE UNIT.

NOTE: DO NOT ADD MORE THAN 9 LITERS OF

COOLANT INTO THE RESERVOIR.

WARNING

AT FIRST STARTING OF THE COOL ARC®50

RESERVOIR FILL CAP MUST BE REMOVED FOR A

MOMENT TO AVOID GENERATE PARTIAL VACUUM IN

COOLING SYSTEM DURING FILLING (THE PUMP

MUST BE FLOODING).

The fill cap contains a pressure release air hole.

Be certain to replace the reservoir fill cap when the

reservoir is full. Operation of the COOL ARC®50 cooler

without the fill cap in place can cause poor cooling

efficiency, evaporation loss of coolant, and low product

life.
