ROUTINE MAINTENANCE
Remove accumulated dust and dirt from the internal
components of the cooler by blowing it out with a low-
pressure air hose or removing the dust and dirt with a
vacuum hose.
PERIODIC MAINTENANCE
In dirty or dusty environments or if biological growth
occurs in the coolant, it may be necessary to flush the
coolant reservoir. Drain the old coolant, rinse the
inside of the reservoir and circulate rinsing solution
through the coolant system. Add new coolant when
cleaning is finished. It is recommended to flush the
coolant at least once a year. A cooling system free
from debris offers increased cooling efficiency and
longer pump and torch life. See the Coolant
Treatment Recommendation in this “Maintenance
Section”.
NOTE: Pure solutions and mixtures of, or materials
(i.e. towels wetted) with ethylene glycol are toxic to
humans and animals. Special precautions should be
taken when discarding toxic material, do not pour this
mixture down any drain. Contact the local EPA office
for responsible disposal methods or for recycling infor-
mation.
HEAT EXCHANGER
To maintain maximum cooler efficiency, the heat
exchanger should be kept free of dust and dirt build-
up. Clean the heat exchanger periodically using a vac-
uum hose or a low-pressure air line. Avoid placing the
unit near a flux hopper or a flux waste container. A
clean heat exchanger offers better cooling perfor-
mance and longer product life. In extremely dirty envi-
ronments, it may be necessary to remove the heat
exchanger completely from the cooler and clean the
fins with soap and water. Use care to avoid damaging
the fins.
RESERVOIR COOLANT LEVEL
The reservoir volume should be checked daily before
using the cooler. Remove the reservoir fill cap and
check the coolant level. The reservoir is full when the
coolant level is just below the reservoir fill opening.
Keep the reservoir full, especially after disconnecting
the water lines or changing the accessory being
cooled.
COOLANT TREATMENT
RECOMMENDATION
This procedure is intended to provide a means of
reducing the objectionable amount of fungal and bac-
terial contamination that has occurred in COOL ARC®
35 water coolers and cooling systems.
Additive:
The recommended additive can be purchased at local
pool supply stores. An example is "Maintain Pool Pro
30% Non-Foam Algaecide".
Limitations:
• The additive should be used with fresh coolants con-
taining only pure water.
• This additive should not be used with coolants con-
taining any other substance, including antifreeze
substances.
• No other additives shall be used with the specified
coolant that has been treated with the recommended
additive.
• This procedure is no permanent substitute for a peri-
odic maintenance schedule for the specified coolers
• A 1-quart bottle of additive is sufficient to disinfect
and treat about 1000 coolers.
• Check with the manufacturer of your guns or
torches to be sure that this procedure is compat-
ible with your equipment.
COOL ARC® 35
SAFETY PRECAUTIONS
ELECTRIC SHOCK can kill.
• Disconnect input power by remov-
ing plug from V310-T/V311-T before
working inside Cooler.
• Do not touch electrically “hot” parts
inside Cooler.
• Have qualified personnel do the installation,
maintenance and troubleshooting work.
