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 cast- ers 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 sup- plied 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 ship- ment, 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 cool- er 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 dis- posal 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 pro- tection 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 STOP- PERS.

When adding coolant to the Under-Cooler cart,

UNPLUG THE COOLER BEFORE FILLING THE COOLANT RESERVOIR:
