Lux Products TX9000TS warranty Operating Instructions

18.Verify that the system and its fan are operating properly. When set to a high temperature, the heating system should provide warm air after a short time. Likewise a cooling system should provide cool air after a short time. Usually sound from the furnace and air conditioning units can be heard while they are running. The rush of moving air should be heard within a short time after either has been started.

NOTE:

If you have an electric heat system and the blower does not operate after installation, see figure in Section 7 to find the electric/gas heat jumper on the back of the body. Move the jumper to the ELEC position.

19. Your installation is now complete.
