(*1) A fan unit is a set of a fan motor and a cover for mounting it. A fan
motor can be replaced separately from the fan unit. The fan unit
A06B-6110-C604, enclosed in parentheses, cannot be dismounted
from the outside. So replace only the fan motor, which can be
dismounted from the outside. (See Section 4.2, "How to Replace
the Fan Motor.")
(*2) The SVM3-20/20/20i has, within its housing, a fan motor for
cooling the heat sink fins on the power transistor.
