WARNING
WARNING
Disconnect power source before installing or servicing. Failure to disconnect power source can
result in fire, shock or serious injury.
1. Patterson products should be installed and serviced by qualified technicians only.
2. Follow all local electrical and safety codes, as well as the National Electric Code (NEC) and the
Occupational Safety and Health Act (OSHA) in the United States.
3. The unit should be installed, protected and fused in accordance with latest issue of the National
Electrical Code, MEMA Standard Publication No. MG2 and local codes.
4. Motor must be securely and adequately grounded. This can be accomplished by wiring with a
ground, metal-clad raceway system, using a separate ground wire connected to the bare metal of
the motor frame, or other suitable means.
5. Always disconnect power source before working on or near a motor or its connected load. Lock
open position and tag to prevent unexpected application of power.
6. In accordance with OSHA requirements, guarding is required if unit is mounted less than 7 feet
above floor or where workers have access.
7. Keep hands and clothing away from moving parts.
8. Be careful when touching the exterior of an operating motor; it may be hot enough to cause injury.
This condition is normal if operated at a rated load and voltage and built to operate at higher
temperatures.
9. Protect power cable from coming into contact with sharp objects.
10. Do not tangle power cable and never allow cable to come in contact with oil, grease, hot surfaces
or chemicals.
11. Make sure that the power source complies to the requirements of your equipment.
When looking at the front of the fan, the blade should be turning clockwise. If it does not, the electrical
connection wires may need to be reversed. If reversing the wires does not work, contact your factory
representative.
