Dynaflux R2000 Water Recirculator Cooling System

Features:

• Stainless steel construction eliminates coolant contamination due to electrolysis or chemical reactions.
• All units are plumbed with copper tubing and reinforced hose.
• New extended life pump.
• No external plumbing is required because of the closed-loop water system.
• A water-level float gauge and filler cap are combined in a single-unit multi-purpose sight glass which enables the operator to observe return water at a distance.
• The water filter on the pump inlet protects the pump and extends the pumps life.

TO FILL UNIT: Fill the reservoir with distilled water and Dynaflux DEFENSE Anti-Freeze & Pump Lubricant for freeze protection and extended pump life. NOTE: Automotive Anti-Freeze compounds are not recommended for use in this unit as well as it will severely shorten the pump life and VOID manufacturer’s warranty.

INSTALLATION: Place the unit so as not to inhibit airflow to the radiator. For proper hook-up, the torch “out” line is to be connected to the Inert arc adapter labeled “Water In”. The torch “In” line is to be connected to the Inert arc adapter labeled “Water Out”.

DEFENSE ANTI-FREEZE AND PUMP LUBRICANT: Provides year-round protection for Dynaflux water coolers andother closed-loop systems.

PART NO. 927: Ready-to-use (No dilution needed).

PART NO. 929: Concentrate to be diluted with distilled water.

PART NO. 947: Ready-to-use propylene glycol.

DAILY: Check the water level with a float gauge indicator to make sure there is an adequate water level for proper cooling.

NOTE: Add only clean distilled water and anti-freeze / pump lubricant. NEVER use automotive-type anti-freeze solutions!

WEEKLY: Check for airflow by shining a light through the radiator. An airline blow-off gun or water hose can be used to clean the radiator. (Be careful not to use too much pressure because the aluminum radiator fins are fragile.)

YEARLY OR AS REQUIRED: If the radiator becomes coated with greasy welding and grinding dust, remove the radiator and soak it in a mild soap solution until it’s clean.

Clean the pump filters. A pick-up screen is in the tank on a gear pump machine and a “Y” strainer is on the side of a vane pump machine. Clean the strainer by rinsing it with clean water.

Clean the tank and refill with clean distilled water and DEFENSE ANTI-FREEZE  / PUMP LUBRICANT. A common dilution for indoor machines is two (2) parts of water to one (1) part DEFENSE. This will provide freeze protection to 20°F and will dramatically extend the pump life.

Check the fan and bolts on the motor and pump for tightness.

Blow the dust out of the motor. If there is an excessive greasy film on the motor, flush it with an electrical solvent.

Put about 10 to 15 drops of oil in each end-bearing of the motor.

Check and replace frayed or loosened electrical cords and worn water hoses.

Put a pressure gauge on the output of the pump. The pressure is normally set at 50 PSI. A drop in pressure could indicate initial pump failure.
