Source 4WRD Fan
Question
Should the Source 4WRD fan spin any time the fixtures is outputting, or it is driven based off of Ambient Temperature?
Answer
On all Source 4WRD units, the fan should spin up as soon as the fixture begins outputting and continue spinning after output has gone away until the heat is dissipated. If a unit's fan is not spinning while the fixtures is outputting, contact your local dealer.
