No Pressure Flow Rate 1.66 gal/min (6.28 liter/min) Max. Pump Hydraulic Rating (Typical Operation) Discharge Pressure (gage) 53-57 PSIG (365-393 kPa) Flow Rate .45-.60 gal/min (1.7-2.3 liter/min) Reservoir Capacity 2.0 Gallons (7.6 Liters) Recommended Coolant For Use Above Freezing: Clean tap, distilled, or de-ionized water For Use Below Freezing: 50% water and 50% pure ethylene glycol 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. To acquire the proper coolant contact a local welding distributor. 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 substances are virtually impossible to purge from the water lines and heat exchanger. Weight Shipping Reservoir Full (Water) 252 lbs. (114 kg) 267 lbs.

HOT COOLANT CAN BURN SKIN • Always be sure coolant is not hot before doing any work on cooler parts. ROTATING FAN BLADES ARE HAZARDOUS • Do not put your hands near an operating fan. • Keep all equipment safety guards, covers and devices in position and in good repair. Keep hands, hair, clothing and tools away from fans and all other moving parts when starting, operating or repairing equipment. • In some cases it may be necessary to remove safety guards to perform required maintenance. Remove guards only when necessary and replace them when the maintenance requiring their removal is complete. Always use the greatest care when working near moving parts. UNPACKING The packaging of the Under-Cooler cart is designed to withstand shipping abuse, and contains a cardboard liner that surrounds the unit. If any shipping damage has occurred, contact your certified Lincoln distributor or service center. When unpacking the unit, avoid thrusting sharp objects through the carton liner, which may damage the heat exchanger or scratch the case. Below is the recommended procedure for unpacking the Cooler: • Cut banding securing carton and remove carton. • Remove banding that holds the cart to the skid. • Remove screws securing rear bottle tray to skid. • Dislodge front, notched 2 X 4 that secures front casters and remove. • Roll Under-Cooler Cart forward off of skid • Cut banding securing drawers and remove and unwrap handle, upper cylinder support assembly, hoses and hardware package located in the storage drawer of the unit. Save the instruction manual and service directory supplied with the Under-Cooler cart for parts orders and future maintenance service. FILLING COOLANT RESERVOIR (See Section A-1 for recommended coolant.) To avoid freeze damage and water leakage in shipment, the Under-Cooler cart is delivered empty with no coolant in the system. To fill the unit, locate the plastic reservoir fill cap at the front middle of the cooler drawer. Clean tap water, distilled water, de-ionized water, a 50/50 mix of pure ethylene glycol and water can be added into the coolant reservoir. The reservoir fill hole mates with most coolant containers but, to avoid spillage of coolant, a funnel should be placed into the reservoir hole when filling. 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 disposal methods or for recycling information. For best results when using the Under-Cooler cart with Lincoln torches, use distilled or de-ionized 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 mixture and should be ordered from a local welding distributor. WARNING When using the Under-Cooler cart, DO NOT USE OIL BASED COOLANTS OR COOLANTS THAT CONTAIN RUST INHIBITORS OR LEAK STOPPERS. When adding coolant to the Under-Cooler cart, UNPLUG THE COOLER BEFORE FILLING THE COOLANT RESERVOIR: ADDING COOLANT: Carefully add 2 gallons (7.6 liters) of coolant through a funnel into the coolant reservoir fill hole. AVOID SPILLING COOLANT INTO THE DRAWER OR ONTO THE PUMP MOTOR. UNDER-COOLER CART A-3 A-3 INSTALLATION CAUTION NOTE: DO NOT ADD MORE THAN 2 GALLONS (7.6 LITERS) OF COOLANT INTO THE RESERVOIR. 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. Simply press on the inside center of the fill cap until the cap snaps into place. Operation of...
