ACP MTR-556 DP Mounting instructions

READ INSTRUCTIONS BELOW CAREFULLY BEFORE ATTEMPTING TO INSTALL, OPERATE OR SERVICE SHUTTER MOTOR.
RETAIN INSTRUCTIONS FOR FUTURE REFERENCE.
We recommend shutter not be mounted closer to the fan than 1/3 the diameter of fan blade. Do not force
shutter into opening! Do not open shutter by lifting individual blades! Do not install shutter leaning forward or
backward!
General Safety Information
1. Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA) in the United States.
2. Motor must be securely and adequately grounded. This can be accomplished by wiring with a grounded,
metal-clad raceway system, by using a separate ground wire connected to the bare metal of the motor
frame, or other suitable means.
3. Always disconnect power source before working on or near a motor or its connected load. If the power
disconnect point is out-of-sight, lock it in the open position and tag to prevent unexpected application of
power.
4. Protect the power cable from coming in contact with sharp objects.
5. Do not kink power cable and never allow the cable to come in contact with oil, grease, hot surfaces, or
chemicals.
6. Make certain that the power source conforms to the requirements of your equipment.

Installation of Fiberglass Motorized Wall Shutters
1. Shutter frame should be mounted level and
squarely on outside wall. Care should be taken not
to twist the shutter frame. Never cover
shutter with siding or masonry work. Shutter should
be mounted so it can be removed any time in
case of damage.
2. Use tie rod only to test opening and closing of
shutter.
3. Shutter should operate as freely after installation
as it did before.
4. Caulking compound is recommended between
shutter frame edges and the wall.
5. Clean and lubricate shutter at the same time that
the fan is lubricated and cleaned.
