Greenheck Fan Modutrol IV User Manual
APPLICATION
The Series 41 and Series 81 Modutrol IV Motors are
2-position (line- and low- voltage, respectively) spring-return
motors. They are used to operate dampers or valves in
applications where it is necessary or desirable to have the
controlled element return to the starting position in the event
of power failure or interruption.

INSTALLATION
When Installing this Product...
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous
condition.
2. Check the ratings given in the instructions and on the
product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect all power supplies before installation.
Motors with auxiliary switches can have more than
one disconnect.
CAUTION
Equipment Damage Hazard.
Can damage the motor beyond repair.
Never turn the motor shaft by hand or with a wrench.
Forcibly turning the motor shaft damages the gear
train and stroke limit contacts.
Location
Allow enough clearance for installing accessories and motor
servicing when selecting a location (see Fig. 1). If located
outdoors, use liquid-tight conduit connectors with the junction
box to provide NEMA 3 weather protection. If mounted
outdoors in a position other than upright, install a 4074ERU
Weatherproofing Kit and liquid-tight connectors to provide
NEMA 3 protection.
CAUTION
Motor Damage Hazard.
Deteriorating vapors and acid fumes can damage
metal parts.
Install motor in areas free of acid fumes and other
deteriorating vapors.
In excessive salt environments, mounting base and screws
should be zinc or cadmium plated, not stainless steel or
brass. Use the 220738A Adapter Bracket for mounting on
these surfaces.
