Filling The Reservoir

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
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.
AVOID SPILLING COOLANT INTO THE FRONT
CASING OF THE UNIT.
NOTE: DO NOT ADD MORE THAN 9 LITERS OF
COOLANT INTO THE RESERVOIR.
AT FIRST STARTING OF THE COOL ARC
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
without the fill cap in place can cause poor cooling
efficiency, evaporation loss of coolant, and low product
life.
Water Hoses Connection

A FROM HEAT SOURCE (RED)
B TO HEAT SOURCE (BLUE)
Water hoses connection is made with quick water fittings
(type 21KATS09MPX) which are equipped with the
automatic outflow blockade.
Before water hoses installing to the cooler, you should
check if the water hose connectors matches to the quick
water connectors placed in the connector block on the
front of the unit. You should:

Take INLET hose (colored or tagged blue on most
hoses) and attach it into the coolant OUT line marked
. Then take the OUTLET hose (colored or tagged
red on most hoses) and attach it into the coolant IN
line marked .
BE CERTAIN THAT NO LEAKS EXIST WHEN COOLER
IS TURNED ON. A LEAK WILL DEPLETE RESERVOIR
VOLUME, CAUSE
PERFORMANCE AND REDUCE GUN, TORCH OR
PUMP LIFE.
