Performance Curves based on 100°F (55.56°C) E.T.D. or Entering
Temperature Difference (E.T.D = Entering oil temperature minus ambient
air temperature). SAE #10 oil @ 200°F (93.33°C).

Notes
1. A three-way thermostatic valve is recommended to bypass the cold oil
around the heat exchanger during start up.
2. Support piping as needed. Flexible connectors must be properly installed
to validate warranty.
3. Coolers should not operate in ambient temperatures below 35°F (1°C).
Consult factory for recommendations.
4. The fan cannot be cycled.
5. AOL coolers operated outdoors must be protected from weather.
Consult factory for recommendations.
6. If duct work or additional static resistance is added to the cooler
airstream, an auxiliary air mover may be required.
7. Can be mounted for horizontal air flow, with oil in at bottom port.
Maintenance
Periodic cleaning of the fins with compressed air is needed to remove the
accumulation of dirt and dust. If the inside of the tubes need to be cleaned of
oil and carbon, use a chlorinated solvent. Do not use strong solvents. Do not
use acids or caustic cleaners.
