TURNING THE SYSTEM "ON"
CAUTION
After connecting the Precision Tig and Tig Torches per Installation Section, plug the unit into

The following should always be observed when operating the
•Check the coolant reservoir level daily.
•Keep the reservoir full especially after changing any water lines.
•The cooler should turn on as soon as an arc is struck and remain on approximately 8 min. after welding is stopped.
•Be certain that the cooler is ON by checking the flow under the fill cap.
•Never operate the cooler with the reservoir fill cap removed after checking the flow.
•Avoid placing the
•Avoid kinking or putting sharp bends in any water lines.
•Keep all water lines clean and free of any block- age.
•Do not operate cooler without coolant in reser- voir. Never run pump dry.
•Never lift the Precision TIG by its lift bale once the
•Never lift the Precision TIG and
You will be able to hear the fan running and feel air- flow out of the back of the unit when the cooler is operating. The cooler will run continuously unless it is plugged into the switched receptacle on the power source (bottom 115V receptacle).
The coolant FLOW INDICATOR is accessed by removal of the fill cap. Actual return flow is directly vis- ible, via the fill opening of the reservoir with the draw- er open. SHUT THE COOLER DRAWER DURING NORMAL OPERATION.
When first starting the unit, check all of the coolant hoses to insure that no water leaks are present. Water leakage causes poor welding performance, poor cooling performance, low welding component life and potential electrical safety hazards.

Unlike other water coolers that depend on bulky reser- voir size, the high efficiency components of the Under- Cooler cart allows the reservoir size to be small. The result is a lightweight unit, in a drawer with additional storage space for welding accessories.
