Lincoln Electric IM10134 COOL ARC 55 S WATER COOLER - Manual (Page 9)

A-3 INSTALLATION
COOL ARC ® 55 S
A-3
FILLING THE COOLANT RESERVOIR:
Recommended Coolant
• For Use Above Freezing: Clean tap, distilled or de-
ionized water.
• For Use Below Freezing: 50% water and 50% pure
ethylene glyco (reagent or industrial grade) mixture.
• DO NOT USE: Automotive anti-freeze that contains
rust inhibitors or leak stoppers.
These coolants will damage the pump and block the
small internal passageways of the heat exchanger,
affecting cooling performance.
• DO NOT USE: Pre-packaged welding industry
coolants. These coolants may contain oil-based
substances, which attack the plastic components of
the cooler. Once added to the cooler, these sub-
stances are virtually impossible to purge from the
water lines and heat exchanger.
To avoid freeze damage and water leakage in ship-
ment, the COOL ARC
® 55 S unit is delivered empty
with no coolant in the system. To fill the unit, locate
the plastic screw on reservoir fill cap at the front of the
unit and remove by turning counter-clockwise.
Clean tap water, distilled water, de-ionized water, a
50/50 mix of pure ethylene glycol and water, or any
other coolant specified by the manufacturer of the
water cooled product that the Cooler is used with, can
be added into the coolant reservoir. The opening of
the fill cap mates with most coolant containers but, to
avoid spillage of coolant, a funnel should be placed
into the reservoir hole when filling the COOL ARC
® 55
S.
NOTE: Pure solutions and mixtures of, or materials
(i.e. towels) wetted with ethylene glycol are toxic to
humans and animals. They must not be haphazardly
discarded, especially by pouring liquids down the
drain. Contact the local EPA office for responsible dis-
posal methods or for recycling information.
For best results when using the COOL ARC ® 55 S
with Lincoln guns or torches, use distilled or de-ion-
ized water, although if not available, tap water can be
used. If protection from freezing is desired, use a 50%
water and 50% pure ethylene glycol (reagent or indus-
trial grade) mixture. An alcohol and water mixture is
also acceptable.
When using the COOL ARC ® 55 S with other prod-
ucts, consult the manufacturer's instruction manual for
recommended coolants.
DO NOT USE OIL BASED COOLANTS OR COOLANTS
THAT CONTAIN RUST INHIBITORS OR LEAK STOPPERS.

UNPLUG THE COOLER BEFORE FILLING THE COOLANT
RESERVOIR:
Carefully add 2.375 gallons (9 liters) of coolant
through a funnel into the coolant reservoir fill hole.
The cooler is "FULL" when the coolant lies just below
the coolant reservoir opening .
NOTE: DO NOT ADD MORE THAN 2.375 GAL-
LONS (9 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. Operation of the COOL ARC
® 55 S
without the fill cap in place can cause poor cooling
efficiency, evaporation loss of coolant and reduced
product life.
