VII. Fan / Blower Maintenance
A high pressure blower requires a certain amount of resistance which will prevent motor
over amperage.
Make sure power source matches wire voltage configurations.
Check set screw and key in fan wheel, make sure fan wheel is secure. Fan blower should
not vibrate.
1. Electrical -
Failure to follow instructions and safe electrical procedures could result in serious injury or death.
Disconnect all power and discharge all capacitors before servicing. Install and ground per local and national
codes. Consult a licensed electrician with questions or if repairs are required.
Electrical Connections -
A.) All wiring, fusing, and grounding must comply with National Electrical Codes and local codes.
B.) To determine proper rotation and voltage connections, refer to the Wire Diagram of this manual.
C.) Use the proper size of line current protection and motor controls as required by the National Electrical Code
and local codes. Recommended use is 125% of full load amps as shown on the nameplate for motors with
40 degrees Celsius ambient and a service factor over 1.0. Recommended use is 115% of full load amps as
shown on the nameplate for all other motors. Do not use protection with larger capacities than recommended.
Three phase motors must have all three phases protected.
2. Cleanliness -
Keep both the interior and exterior of the motor free from dirt, water, oil, and grease.
3. Safety -
Motors should be installed, protected and fused in accordance with latest issue of National Electrical
Code, NEMA Standard Publication No. MG 2 and local codes. Rotating parts such as pulleys, coupling, external
fans, and unusual shaft extensions should be permanently guarded. Keep hands and clothing away from
moving parts. Electrical repairs should be made by trained, qualified personnel only.
