To prevent overheating, make sure

cooling unit is positioned so airflow

is not restricted.

Y When using coolant system

with a welding power source

with a water valve, bypass

water valve on welding pow-

er source by connecting di-

rectly to torch/gun to avoid

overheating, or damage to

coolant system.

Y To prevent tipping when

placing unit on uneven or tilt-

ing surfaces, properly se-

cure the coolant system to a

wall, stationary support, or

equivalent rigid structure.

1 Motor

Remove plugs and put about 15

drops of SAE 20 motor oil into each

oil port. Replace plugs, and reas-

semble unit.

3 Filter Cap

Place cloth or suitable container un-

der nut, and remove nut.

4 Strainer

Rinse strainer with clean water.

Reinstall parts. Remove cloth or

container, and reinstall wrapper.

. Relief valve is factory set at 60

psi (414 kPa), and normally

needs no adjustment: Only ad-

just if replacing motor.

5 Pressure Gauge

6 Relief Valve Adjustment

Screw

Connect gauge to Coolant Out fit-

ting as shown. Block or plug any

output fitting on gauge.

Turn On power, and adjust pres-

sure adjustment screw as needed.

Turn Off power. Disconnect gauge

and reinstall nut and wrapper.

. If replacing hoses, use hoses

compatible with ethylene gly-

col, such as Buna-n, Neo-

prene, or Hypalon. NOTE:
