INSTALLING TYPE II FAN SPEED
SELECTOR KIT
A fan speed selector may be required for a mer-
chandiser to operate for certain applications
such as Type II conditions . However, if the
speed key is removed, the fans will return to the
default fan speed, which typically aligns with
Type I operation . Each key is configured from
the factory to operate for the specific model for
which it was ordered .
ANSI/NSF-7 Type II – Display Refrigerator / Freezer
Intended for 80°F / 55%RH Ambient Application
Contact your Hussmann representative to
order this kit if the cases in your lineup are
required to operate in Type II conditions . The
selector will operate up to 6 fan motors . Only
an experienced electrician should install the fan
selector .
1 . Mount the selector inside of the wireway of
each case . Insert the speed key into the selector .
Insert harness connector (2-pin) into the Selec-
tor . The 2-pin side supplies power to the selec-
tor . It can be used with 110V or 220V circuits .
2 . Insert the harness connector (3-pin) into the
selector . The 3-pin side sends a signal to the fan
motor and the fan speed RPM is now changed
to the new setting .
Harness Routing and Field Connections are
shown on the next Page .
