To prevent overheating, make sure cooling
unit is positioned so airflow is not restricted.
Y If welding power source has a water
valve, do not connect hoses to wa-
ter valve. Connect hoses as shown.

2 Coolant In Hose
Fittings have 5/8-18 left-hand threads.
Connect hoses with proper fittings as
shown. Some power sources may require
a TIG block.

or circuit breakers is recommended. Rec-
ommended fuse or circuit breaker size is
15 amperes.
Operation:
Fill tank with proper coolant. Use table in
Section 6 to select proper coolant. Maintain
coolant level at approximately 1 in (25 mm)
below top of filler neck. Connect hoses as
shown. Unit turns on when plugged in.

1 Coolant Filter
Unscrew housing to clean filter.
Changing coolant: Drain coolant by
tipping unit to rear, or use suction
pump. Fill with clean water and run
for 10 minutes. Drain and refill with
coolant (see section 6).
2 Motor (If Motor Is Equipped
With Oilers)
Remove plugs and put about 15
drops of SAE 20 motor oil into each
oil port. Replace plugs.
. If replacing hoses, use hoses
compatible with ethylene gly-
col, such as Buna-n, Neo-
prene, or Hypalon. NOTE:
Oxy-acetylene hoses are not
compatible with any product
containing ethylene glycol.
Install cover if removed.

11. Troubleshooting
Trouble Remedy
Coolant system does not work. Be sure input power cord is plugged in to energized receptacle.
Check line fuses or circuit breaker, and replace or reset if necessary.
Motor overheated. Unit starts running when motor has cooled.
Have Factory Authorized Service Agent check Power switch S1 and motor (Mot).
Decreased or no coolant flow. Add coolant.
Check for clogged hoses or coolant filter. Clean filter or clean / replace hoses if necessary.
Disconnect pump, and check for sheared coupling. Replace coupling if necessary.
