4. Closely examine all cooling connections and verify that there are no leaks.
Operating the laser at coolant temperatures above 22 °C (72 °F) may result in decreased
performance and/or premature failure of electronic components.

Because v40 OEM air-cooled lasers are shipped without cooling fans, customers must provide some
type of air cooling to prevent overheating. NOVANTA recommends an airflow of at least 140 cubic feet
per minute for each of the two required fans. Figure 1-5 illustrates the fan placement necessary to keep
the laser's heat sink temperature below 45 °C. (113 °F). To provide proper airflow, cooling fans should
have a diameter of approximately 4.5–5 inches (114–127 mm) and have at least 2.25" (57.2 mm) of
unobstructed clearance between the outside edge of the fan housing and any mounting surface or
enclosure. Because of the heat generated by internal RF circuitry, establishing significant airflow evenly
over the entire surface area of the combined laser/RF chassis is vitally important to the performance and
longevity of the laser.
Important Note: The air-cooled OEM laser's front plate is not compatible with the fan kit used on
fan-cooled v40 lasers. Because a different front plate is required, the factory-supplied fan kit
cannot be retrofitted to air-cooled OEM lasers in the field; it must be installed at the factory.
Caution: Possible Equipment Damage
