Direct-Drive

Blowers

Description

ayton direct-drive blowers are specifically engineered for air-conditioning,

D
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.

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.

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.

EXCEED THE PURCHASE PRICE PAID.

WARRANTY DISCLAIMER. A DILIGENT EFFORT HAS BEEN MADE TO PROVIDE PRODUCT INFORMATION AND ILLUSTRATE
THE PRODUCTS IN THIS LITERATURE ACCURATELY; HOWEVER, SUCH INFORMATION AND ILLUSTRATIONS ARE FOR THE SOLE
PURPOSE OF IDENTIFICATION, AND DO NOT EXPRESS OR IMPLY A WARRANTY THAT THE PRODUCTS ARE MERCHANTABLE,

national and local codes and regulations, and be sure that the product, installation, and use will comply with them.

Certain aspects of disclaimers are not applicable to consumer products; e.g., (a) some jurisdictions do not allow the exclusion
or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you; (b) also,
