SAFETY PRECAUTIONS
- Even when using the Magnum Cooler in an “on-
demand” application, the power to the Cooler should
be turned off when welding is not taking place for a
long period of time.
- Be certain that the Cooler is on (power switch in the
“|” position) before beginning to weld, especially
when using the Cooler in the demand system.
- Never operate the Cooler with the reservoir fill cap
removed.
- Avoid placing the Cooler near areas of extreme
heat.
- Avoid placing the Cooler near a flux hopper or an
area where dust build-up is extreme.
- Avoid kinking or putting sharp bends in any water
lines.
- Keep all water lines clean.
LIGHTED POWER SWITCH
A long life, lighted power switch is located at the left
side on the control panel. When switched “ON”, the
switch will be pressed toward the “|” symbol.
Because it will only light when the Cooler is pumping
coolant, the switch serves as an indicator for the
Magnum system monitor. For proper operation, the
switch should beam steadily when coolant is pumping
and remain unlit when flow is stopped. Reference the
Magnum system monitor sections for an explanation.
TURNING THE SYSTEM ON
After filling the reservoir and connecting the coolant
hoses to the Magnum Cooler per the Installation
Sections, plug the unit into an electrical receptacle for
start-up operation. Be certain that the power input into
the unit matches the Cooler’s rated input. Both Cooler
10-I and 20-I cordsets contain a 90 angled CEE 7/4,
7/7 Schuko compatible plug. The plug mates with an
auxiliary receptacle located at the back of many inter-
national Lincoln power sources for power supply to a
Magnum Cooler 10-I and 20-I when placed at the
back of a Lincoln K874, K840-1*, K841-1*, and K842-
1* undercarriage.
