SAFETY PRECAUTIONS

WARNING

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.

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.
