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.

3.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.

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 blower is 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.

H8. 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 conforms to 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 such as a grounded metallic raceway or ground wire system. Be sure the motor to housing ground wire is secure.

2.Wiring connections:

a.For Models 1XJX7 and 1XJX8 connect the two leads to the appropriate power source.

b.For Models 1XJX9, 1XJY1, 1XJY2, 1XJY3 and 1XJY4, refer to Figure 2, page 3 for wiring.

NOTE: The purple lead in the wiring diagrams must always be used as one of the electrical connections. All leads not used must be “dead ended” (taped off).

3. Unit is ready for operation.

Specifications and Performance

Operation

After the blower is installed and all duct work is re-attached, measure the current input to the motor and compare with the nameplate rating of the motor (See “Specifications and Performance”) to determine if the motor is operating under safe load conditions.

Make certain that the blower is

operating within the static pressure limits shown in the “Specification and Performance” chart; if not, motor overload will result.

Maintenance

Do not depend on any switch as the

sole means of disconnecting power when installing or servicing the fan. If the power disconnect is out-of-sight, lock it in the open position and tag to prevent application of power. Failure to do so may result in fatal electrical shock.

LUBRICATION

The motor bearings are permanently lubricated ball-bearings.
