2-2. COOLANT HOSES AND CONNECTIONS
{Figure 3-1} - Both the PUMP OUTLET and the
RETURN LINE are 5/8-18 female, left-hand fittings,
which are standard connections on most inert gas tor-
ches/guns. To connect coolant hoses (not provided),
proceed as follows:
INCORRECT HOSES will damage
unit.
® Do not use oxyacetylene hoses.
e Use hoses compatible with coolant such as
Neoprene, Buna-N, Hypalon, or equivalent.
Incorrect hoses will degrade and plug or damage the
coolant system.
OVERHEATING Gas Tungsten Arc Welding
(GTAW) torches and Gas Metal Arc Welding
(GMAW] guns can damage torches and guns.
e /f using a water-cooled torch/gun and recir-
culating coolant system, do not make connections
from the coolant system to water valve; instead,
make connections directly from the coolant
system to torch/gun hoses.
1. Connect a proper hose from PUMP QUTLET fit-
ting on the coolant system to the coolant in fit-
ting on the torch/gun.
2. Connect a proper hose from RETURN LINE fit-
ting on the coolant system to the coolant out fit-
ting on the torch/gun.
OM-821 Page 2
3. Be sure that all coolant connections are airtight
to provide maximum cooling efficiency.

INCORRECT COOLANT will damage
unit.
® [Do not use tap water, automotive antifreeze, or
plain distifled or deionized water.
© (Use only a mixture of pure commercial ethylene or
propylene glycol and/or water-soluble lubricants
in distifled or deionized water.
Any lubricants must be specifically designated for use in
commercial cooling systems, Corrosion inhibitors for
copper or brass are beneficial and may be included in
either the lubricant or the glycol. However, do NOT use
inhibitors for aluminum,
FAILURE TO COMPLY WITH THESE INSTRUCTIONS
MAY VOID THE WARRANTY.
Where freezing conditions may be encountered, mix
coolant according to the manufacturer's recommenda-
tions for the ambient temperature encountered.
Coolant tank capacity of this unit is 12 gallons (45
iiters); however, length of coolant hoses will directly af-
fect the amount of coolant needed in the unit. Add
coolant in sufficient amounts to compensate for coolant
in hoses. For 5/16 in. (8 mm} 1.D. hose, add approx-
imately 1.5 quarts {1.42 liters} per 100 ft. (30.5 m)* of
hose. For 3/8 1.D. in. {9.5 mm) hose add approximately
2.25 quarts (2.13 liters) per 100 ft. (30.5 m)* of hose.
*Cambined total of 50 ft. (15.24 m) Coolant In and 50
ft. {15.24 m} Coolant Out hose.
To fill coolant tank, proceed as follows:
XIN INCORRECT COOLANT LEVEL can
damage coolant system and torch/gun.
® Maintain correct coolant level at all times.
1. Open coolant tank access door {see Figure 3-1).
2. Fill coolant tank with correct coolant until the
coolant level is even with the center of the view-
ing port.
3. Close and secure access door.
DTF Be sure coolant tank access door IS
closed and secured when not being serviced to keep dirt
out of tank.
WEOLEY UNE After approximately 100 hours of
break-in time, flush system and change coolant accor-
ding to Section 4-2.

3-1. BY-PASS VALVE OPERATION (Figure
3-1) - A by-pass valve is installed in the pump
discharge line to provide pressure relief in case the
discharge line should be closed for any reason. Factory
setting of the by-pass valve is 45 psi {310 kPa}. This set-
ting can be adjusted but should not exceed the tor-
ch/gun manufacturers recommended maximum
pressure rating (see Section 4-4},
It may be necessary to increase the
pressure setting to compensate for long extension
hoses or for pumping to elevations above the cooling
system (see Section 4-4).
3-2. VIEWING PORT (Figure 3-1) - When the
coolant level is in the center of the viewing port, the
coolant tank is filled to the proper capacity. In addition,
the splashing of the coolant against the viewing port in-
dicates that the coolant system is functioning properly.

e Circulate and flush clear water through entire
system, and replace coolant every six months
after break-in period.
If coolant system is properly maintained, cooling pro-
bierns should not occur. If a problem is suspected,
remove and clean coolant tank and strainer with clear
water. Use proper coolant according to Section 2-3.
4 - 3. MOTOR MAINTENANCE
KELLER ELECTRIC SHOCK can kill; MOVING
PARTS can cause serious injury.
® Do not touch live electrical parts.
® Keep clear of moving parts.
® Disconnect input power plug from receptacle
before removing wrapper to oil motor.
Every six months oil the bearings on the motor. Use 150
drops (approximately 1 teaspoon) of SAE 20 motor oil
in each bearing. Continue to service motor regularly ac-
cording to manufacturer's recommendations on motor
nameplate.
4-4. BY-PASS VALVE ADJUSTMENT (Figure
3-1) - In most cases, the by-pass vaive setting of 45
(310 kPa) will satisfy the pressure required to protect
most torches/guns. Circumstances that may require by-
pass valve adjustment are torch/gun operations at
elevations above the coolant system, long hose exten-
sions depending on 1.D. and length of hoses, or high
friction of torch/gun and hoses.
For every 10 ft. {3.1 m) that torch is elevated above
coolant system, increase by-pass pressure by approx-
imately 4-1/3 psi {30 kPa). Consult torch/gun manufac-
turer's requirements for coolant flow and make ad-
justments accordingly.
To adjust by-pass valve pressure, proceed as follows:
ELECTRIC SHOCK can kill; MOVING
PARTS can cause serious injury.
® Do not touch live electrical parts.
e Keep clear of moving parts.
INCORRECT BY-PASS VALVE AD-
JUSTMENT can cause personal injury and equip-
ment damage.
® Do not set by-pass valve pressure above the tor-
ch/gun manufacturer's recommended maximum
pressure rating.
The higher the setting of the by-pass
valve pressure, the more coolant flows through the
systern per minute. Proper pressure is necessary to ade-
quately cool the torch/gun.
OM-621 Page 4
1. Disconnect input power plug from receptacle.
2. Remove motor/pump access panel.
3. Disconnect torch/gun hose from the PUMP
QUTLET fitting on the unit.
4. Connect a pressure gauge with a minimum of
200 psi (1379 kPa) capacity at maximum scale
reading to the PUMP QUTLET fitting. Install
gauge using a 5/8-18 male, left-nand fitting
either directly onto the unit or with a good quali-
ty high pressure hose between the unit and
gauge. Block or plug any gauge output fitting.
Flow should not go through gauge; just to it.
5. Remove cap nut from by-pass valve adjustment
screw using a 3/4 in. socket. Be sure fiber
washer does not fall off adjustment screw when
removing the cap nut.
6. Use a 3/4 in. socket to just loosen the adjust-
ment screw jam nut. Be sure fiber washer re-
mains on the adjustment screw.
7. Reconnect input power plug, and energize
coolant system. Make pressure adjustments with
a screwdriver and use the gauge to check for
desired pressure setting as foliows:
Turn adjustment screw clockwise to increase
pressure or counterclockwise to decrease
pressure as necessary. Do not overadjust the
screw; slight movement will change pressure
significantly.
8. Disconnect input power plug from receptacle
after adjustments are made and tighten the ad-
justment screw jam nut. Be sure fiber washer is
on the adjustment screw.
9. Reinstall cap nut onto by-pass valve adjustment
| screw.
10. Remove pressure gauge from PUMP OUTLET
fitting, and reconnect torch/gun hose to fitting.
11. Reinstall the motor/pump access panel.
12. Reconnect input power plug, energize coolant
system, and resume operation.
