Electrical installation work and electrical wiring must be done by qualified persons in accordance with all applicable codes and standards.

Do not connect the power supply until the fan is completely installed. Make sure electrical service to the fan is locked in the OFF position.

While we recommend that the fan be left running at all times, choose a fan suitable for fan speed control use. Pulling too much air through the composter could cool the process, if the temperatures are below the minimum recommended by the manufacturer. A number of users have found it advantageous to have a wall-mounted fan speed controller near the toilet, so that the fan can be optimally efficient, operated at minimum noise/air velocity and shut off temporarily while it is being serviced.

Caution: The fan can be turned on immediately following service. Never place a switch where it can be reached from a tub or shower.

The incoming electrical service should come through the connector clamp and the knockout on the junction box. The necessary connection must be made in accordance with state electrical codes. You must have a proper ground, unless the fan motor is isolated within a plastic housing, where case grounding is not necessary.

Connections, clamp connector, and terminal box screws must be secured.
