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®
40 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 720 coolers.

• Check with the manufacturer of your guns or

torches to be sure that this procedure is compat-
ible with your equipment.

Prepare the disinfectant:

Make a quantity of only what is needed to avoid an
excess Bulk preparation (for coolers serviced in quan-
tity):

8.775 L (2.325 gals.)  of pure, fresh water per cooler
1.625 ml of additive per cooler. Example: for 100 cool-
ers, add 162.5 ml to 232.5 gals. of pure fresh water
Pour 7.55 L (2.0 gals.) of disinfectant into the empty
reservoir. Recap the reservoir, tape over the air vent
in the cap, roll disinfectant around the inside the reser-
voir to thoroughly coat all of its surfaces. Remove the
tape from the reservoir cap. Prime the cooling system
by positioning cooler horizontally and circulate disin-
fectant through it for 10 to 15 minutes. Drain disinfec-
tant from the cooling system. Do not reuse this solu-
tion. Add new, fresh coolant to the cooling system.
Add 1.225 L (0.325 gals.) of fresh disinfectant to the
system by pouring it into the reservoir, then reduce
the concentration to the nominal 30 ppm:

Add the balance 6.325 L (1.675 gals.) of fresh, pure
water to the reservoir to create the treated coolant
concentration. Prime the cooling system.

PUMP INLET STRAINER 

Poor cooler performance can usually be traced to a
partially or completely blocked pump inlet strainer.
This is a user-serviceable item and can be cleaned
and reused, or replaced. Continued pump operation
with a blocked filter can cause:
• Voiding of cooler service warranty
• Cavitation damage to the pump headʼs inlet areas
• Welding accessory damage from overheating due to

insufficient coolant flow rate.

A new or properly cleaned pump inlet strainer should
restore the coolerʼs performance.

For additional service and periodic maintenance
details and for recommended coolants, follow the rec-
ommendations listed below.

Procedure and Preparation:

• Always switch off the COOL  ARC®  40 machine

power

• Always disconnect the COOL ARC® 40 machine

from service input power.

• Always allow the coolant in the system to cool

enough to avoid burn injuries.

• Avoid contact with contaminated coolant. Wear

waterproof gloves and protective eye wear.

• Do not remove the pump relief valveʼs 3/4 in.

acorn hex nut or attempt to adjust the relief valve
setting.

------------------------------------------------------------------------

INSPECT CONDITION OF COOLANT

If coolant is contaminated or old:
• Drain the system of coolant and dispose of it in an

environmentally responsible manner.

• Flush system of old coolant.
• Fill with fresh tap or distilled water, run for ten min-

utes, and drain.

• Proceed to adding coolant..

If coolant is new:
• If clean, dedicated coolant handling equipment,

including a clean siphon pump and a clean holding
tank are available, then proceed to servicing the
Pump Inlet Strainer.

COOL ARC® 40

WARNING

Check coolant level. Add more fresh, pure water if
required, without adding more than 0.475 L (0.125
gal.) of pure water to prevent diluting the coolant addi-
tive.
