Front and rear fan set for LT4670 (user hot swappable).

The LT4670 instrument has two fan units installed, one on the front panel and one on the rear panel. You can replace one of these fan units with the power on. There is a pair of fan units, one for the front panel and one for the rear panel. Note that these fan units are different in shape.

When replacing a fan unit with the power on, install a new fan unit and start the fan quickly after stopping the existing fan. If the fan is stopped for an extended length of time, the internal temperature becomes very high, potentially damaging the instrument.

*Please see instruction manual for specific instructions about fan replacement procedure
