Dayton® Direct-Drive Blowers Description Dayton direct-drive blowers are specifically engineered for air-conditioning, heating and ventilating systems where the blower is mounted within a cabinet or plenum chamber. To minimize vibration, 4-point reinforced mounting brackets have been equipped with rubber isolators. Blowers can be mounted in four variable discharge positions. All motors are permanent split capacitor type (with appropriate capacitor attached) with automatic reset thermal protection. Unpacking 1. Inspect unit for any damage that may have occurred during transit. 2. Shipping damage claim must be filed with carrier. 3. Insure that blower wheel spins freely before installation.

Failure to disconnect power source can result in fire, shock or serious injury. 1. Blower should be installed and serviced by a qualified technician only. 2. 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. 3. Motor must be securely and adequately grounded. This can be accomplished by wiring with agrounded, metal-clad raceway system by using a separate ground wire connected to the bare metal of the motor frame, or other suitable means. 4. Always disconnect power source before working on or near a motor or its connected load. Lock it in the open position and tag to prevent unexpected application of power. 5. In accordance with OSHA requirements, guarding is required if bloweris mounted less than 7 feet above floor or where workers have access. 6. Be careful when touching the exterior of an operating motor; it may be hot enough to cause injury. With modern motors, this condition is normal as they are built to operate at higher temperatures.

It may be hot enough to cause injury. 7. Protect power cable from coming into contact with sharp objects. 8. Do not kink power cable and never allow cable to come in contact with oil, grease, hot surfaces or chemicals. 9. Make certain that the power source conformsto the requirements of your equipment. Do not use in a flammable or explosive atmosphere. Installation 1. Attach the housing supports (ordered separately) to the housing in the desired discharge position. For safety, a lockable disconnect switch should be located near blower so power can be positively disconnected while installing or servicing the fan. Blower frame and motor must be electrically grounded to a suitable electrical ground suc

FAQs

What should be done after unpacking the blower?

Inspect the unit for any damage from transit. File any shipping damage claim with the carrier, and confirm the blower wheel spins freely before installation.

What general safety precautions are required before servicing or installing?

Disconnect the power source before installing or servicing, lock it in the open position, and tag it to prevent unexpected energization. Blower installation and servicing should be done only by a qualified technician, and guarding is required under specified mounting height/access conditions.

How is safe operation verified after installation?

Measure motor current input and compare it with the nameplate rating to ensure the motor runs under safe load conditions. Also confirm the blower operates within the static pressure limits shown in the specifications and performance chart.
