HAZARDOUS
• Do not put your hands near an oper-

devices in position and in good repair. Keep
hands, hair, clothing and tools away from fans
and all other moving parts when starting, oper-
ating or repairing equipment.

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.
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:
-----------------------------------------------------------------------
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.
