hand side of the connector block Again, tightly secure
the connector nut of the hose into the connector block
of the Cooler with an adjustable or 11/16” open-ended
wrench to insure that no leaking occurs. BE CER-
TAIN THAT NO LEAKS EXIST WHEN COOLER IS
TURNED ON. A LEAK WILL DEPLETE RESERVOIR
VOLUME, CAUSE POOR COOLING PERFOR-
MANCE AND REDUCE GUN OR TORCH LIFE.
If the connector nut on a water hose does not mate
with connector block at the back of a Magnum Cooler:
Order: (2) T15007-2 Connector Nuts*
(2) T15008 Nipples*
(2) S10888-35 Hose Clamps*
For proper installation, remove the connector nut from
the water hose by making a straight cut 1/4-1/2” (6-
12mm) away from the nipple located inside of the
hose. Take the nipple and the connector nut, and
insert the nipple into the connector nut so that the
threaded end of the connector nut points away from
the barbed end of the nipple. Place the hose clamp
over the water hose and twist the barbed end of the
nipple into the hose until the shoulder of the nipple is
flush with the end of the hose. Secure the hose onto
the nipple by tightening the hose clamp around the
nipple. No water can leak from the connection if it is
properly attached. Repeat the process for the other
water hose.
NOTE: Be certain that only 5/8-18 left hand male
nuts with clean and smooth threads are used on
your water hoses. Poor connections cause
water to leak at connector block, down hose
lines, and eventually out the case sides of the
unit.
* The connector and nipples listed fit tightly onto 5/32”
(4.0mm) to 3/16” (4.8mm) inner diameter hose, but, if
clamped tightly to the hose can fit up to .250” (6.4mm)
inner diameter hose.
HORIZONTALLY MOUNTING MAGNUM COOLERS
ON LINCOLN TIG POWER SOURCES
Magnum Coolers can be mounted either upright or
horizontally. For a complete compact system,
Magnum 10 or 20 Cooler can be mounted horizontally
on the roof of Lincoln TIG Power Sources using the
optional K559-2 Horizontal TIG Mounting Bracket. For
proper installation, follow the instructions provided
with the kit. (See Figures 3a and 3b)
VERTICALLY MOUNTING MAGNUM COOLERS TO
LINCOLN UNDERCARRIAGES K874, K840-1*, K841-
1*, or K842-1*
When placing the Cooler 10 or 20 at the back of a
Lincoln Undercarriage used in tandem with a Lincoln
MIG power source, order K559-3 Magnum Cooler
MIG Mounting Bracket.
Reference Figure 3c and Table 2 for proper connec-
tion of the bracket to the back bolt pattern of the
Cooler. With the four Phillips head screws supplied,
align the bracket onto the back of the Cooler at the
proper holes displayed in Figure 3c. Do not fully tight-
en the bracket allowing the bracket to slightly move up
and down. Place the Cooler at the back right of the
undercarriage so that the lip of the Cooler bracket
rests on the top of the undercarriage upper cylinder
support. Align the holes of the Cooler bracket with the
holes on the undercarriage upper cylinder support.
Fasten the Cooler bracket with the holes on the
undercarriage upper cylinder support. Fasten the
Cooler bracket onto the undercarriage support with
both 1/4-20 bolts, 1/4-20 hex nuts, plain washers and
lock washers provided. Be certain to tighten all the
fasteners when the installation is complete.
