HEAT EXCHANGER MAINTENANCE
To maintain maximum efficiency, the heat exchanger
should be kept clean from dust and dirt buildup. Clean
the heat exchanger periodically using a vacuum hose
or low pressure air line. Avoid placing the unit near a
flux hopper or a flux waste container. A clean heat
exchanger offers better cooling performance and
longer product life. If extremely dirty conditions exist, it
may be necessary to remove the heat exchanger
completely from the Cooler for a thorough soap and
water cleaning of the cooling fins. Use care to avoid
damaging the fins.
RESERVOIR MAINTENANCE
The reservoir volume should be checked daily before
using the Cooler. Remove the reservoir fill cap and
check the coolant level. Unit is full when the coolant
lies just below the reservoir fill opening with the unit in
an upright position. Keep the reservoir full especially
after changing the water lines.
The Cooler should always be operated with the reser-
voir fill cap on. In areas where dust can be introduced
into the reservoir through water lines or reservoir fill
cap removal, periodically flush the unit out. Dump the
old coolant and rinse the inside of the reservoir. Add
new coolant when finished. A reservoir free from parti-
cle buildup and dirt offers better cooling efficiency and
longer pump, gun and torch life.
S20095-1 Pump Replacement Kit (60 psi) for Magnum
Cooler 20-I Units:
S20095-3 Pump Replacement Kit (45 psi) for Magnum
Cooler 10-I Units:
Both the S20095-1 and S20095-3 Pump Replacement
Kits consist of a molded pump head equipped with all
internal pump components to replace a failed pump or
cracked pump head of a Magnum Cooler. The Pump
Replacement Kit includes a complete pre-assembled
pressure switch assembly and pump assembly.
Although the Pump Replacement Kit costs more than
the Pump Rebuild Kit, the time to install it is less and
saves money when down time is costly. When repair-
ing the Cooler pump, follow the instructions supplied
with the kit. The only tool needed for installing the
S20095-1 or S20095-3 Pump Replacement Kit is a
Phillips head screw driver. Reference Parts Section
for a parts list of the Pump Replacement Kit.
S20095-2 Pump Rebuild Kit for Magnum Cooler 10-I
and 20-I Units:
The S20095-2 Rebuild Kit consists of a all the neces-
sary internal components to rebuild the most common
“soft” pump failure that occurs in a Magnum Cooler.
Water will slowly drip from the pump head when the
pump experiences a “soft” failure. The rebuild proce-
dure is more involved than the pump replacement pro-
cedure but is more cost efficient when labor rates are
low or when down time is not critical. The only tool
needed for rebuilding the pump is a Phillips head
screw driver. Follow the instructions supplied with the
kit when rebuilding the pump head. Reference Parts
Section for the S20095-2 Magnum Cooler Pump
Rebuild Kit.
