Maintenance
Before performing any maintenance, make sure that the Fan Control Module is disconnected from power
by turning OFF the breaker supplying power to the device.
At least once a year, the Fan Control Module should be inspected for maintenance and cleaning. This
includes the following:
• Cleaning dust and any other buildup on the exterior of the Fan Control Module.
• Opening the lid and inspecting the internal parts for any signs of moisture or dust ingression.
• Inspecting the three cord grips on the enclosure. Make sure that the cord grips are tight and that
pulling on cables does not cause them to move. Also make sure the panel mounting nut on the grips
is tight and that the cord grips cannot spin freely under manual rotation. If there is any movement,
tighten the panel mount nut and/or the cord grip nut.
• Inspect the entire enclosure for any signs of damage, especially any that could compromise the
sealing of the enclosure.
There are no user serviceable fuses inside the Fan Control Module.
