SECTION 21
BLOWER ASSEMBLY (A15)
21-1.
For continuous high ambient temperature operation or with the IEEE control option, the blower option
provides additional cooling for the system. The blower as received from the factory will run whenever the unit
is connected to the AC line. However, a jumper shorting out a thermostat in the blower assembly may be
removed so that the fan only operates when high temperature conditions exist. A schematic of the Blower
Assembly is shown in figure 21-1.
