The fans of the KBB/KBB-F and KBF-KBF-F series for belt drive are produced in accordance with the latest technical standards and
our quality assurance programme which includes material and function tests ensures that the final product is of a high quality and
durability. Never the less these fans can be dangerous if they are not used and installed correctly, according to the instructions.
1. GENERAL SAFETY INFORMATION
• Only approved, qualified personnel familiar with the assessment of hazards and risks associated with fans
and with the use of tools and test equipment required to service such fans, should install, operate and
maintain the product. Improper installation can result in electric shock, possible injury due to coming in contact
with moving parts, as well as other potential hazards.
• Before installing, operating and maintenance this fan please read this instructions carefully!
• If the installer or user is unable to understand the information in this manual or has any doubt that a safe and
reliable installation, operation and maintenance of the equipment can be assured, Breeze limited should be
contacted for advice.
• Warnings and safety information relevant to specific operations are contained at the start of the sections to
which they apply.
• When fans are retained in storage, access by unauthorised persons must be prevented with the use of
guards, barriers or secure premises such that fan impellers which may be rotating do not present a hazard.
• Follow all local electrical and safety codes, as well as the National Electrical Code, the National Fire
Protection Agency, where applicable.
• The rotation of the impeller is critical. It must be free to rotate without striking or rubbing any stationary
objects.
• Motor must be securely and adequately grounded.
• The fan' speed is changed, the motor current should be checked to make sure it is not exceeding the motor
nameplate amps.
• Do not allow the power cable to kink or come in contact with oil, grease, hot surfaces or chemicals. Replace
cord immediately if damaged.
• Verify that the power source is compatible with the equipment.
• Only operate the fan in its enclosed state or with properly assembled protective anti-intrusion fittings or with
protective screens.
• The fan must be operated only in accordance with the performance data and the approved medium passing
through.
• Never open access doors to a duct while the fan is running.
• Always disconnect power before working on or near a fan. Lock and tag the disconnect switch or breaker to
prevent accidental power up. Failure to disconnect power source can result in fire, shock or serious injury.
ATTENTION!
DANGER
CAUTION
• When servicing the fan, motor may be hot enough to cause pain or injury. Allow motor to cool before servicing.
• Precaution should be taken in explosive atmospheres.
2. PRODUCT OVERVIEW
The series of cabinet fans with double curve forward/ backward s were developed with KBB/KBB-F and KBF-KBF-F impeller
advanced technologies. They are designed to bear the BS and ISO standard for air performance, sound, and efficiency which are
equivalent to AMCA and DIN standard.
2.1 Construction.
Breeze Cabinet fans are designed and developed on the basis of advanced technology from United Kingdom. It has the features of
high efficiency, low noise, excellent performance, easy installation and so on. The belt drive allows for higher speeds of the impeller
and thus higher volumetric flows with a compact structure size. All fans are statically and dynamically balanced at the factory.

Ducted Inlet Installations:
Ducted Outlet Installations:
Inlet Duct Turns - Installation of a duct turn or elbow too close to the fan inlet reduces fan performance because air is loaded
unevenly into the fan . To achieve full fan performance, there should be at least one fan diameters between the turn impeller impeller
or elbow and the fan inlet.
Discharge Duct Turns- Duct turns located near the fan discharge should always be in the direction of the fan rotation. Fan
performance is reduced when duct turns are made immediately o ffthe fan discharge. To achieve cataloged fan performance there
should be at least one equivalent duct diameters of straight ductwork between the fan discharge and any duct turns.

Inlet Spin - Inlet spin is a frequent cause of reduced fan performance. The change in fan performance is a function of the intensity of
spin and not easily defined. The best solution is proper duct design and airflow patterns. Turning vanes reduce the effects of inlet
spin.

Non-Ducted Installations:
Inlet Clearance - Installation of a fan with an open inlet too
close to a wall or bulkhead will cause reduced fan performance.
It is desirable to have a minimum of three-fourths of a impeller
diameter between the fan inlet and the wall.
Free Discharge - Free or abrupt discharge into a plenum
results in a reduction in fan performance. The effect of
discharge static regain is not realized.
4. INSTALLATION INSTRUCTION
•Move the fan to the desired location.
• Check and tighten fasteners throughout the unit and then fasten securely through mounting holes provided in the base angles.
• The unit must be set level (shimming may be necessary).
• Flexible duct connections and vibration isolators should be used where noise is a factor.
• The motor voltage and ampere rating must be checked for compatibility with the electrical supply prior to final electrical connection.
• Supply wiring to the fan must be properly fused, and conform to local and national electrical codes.

4.2 Guideliness for Noise Control
ŸEnsure transitions close to attenuators are
gradual or better still, remote.
ŸAbrupt transitions immediately adjacent to an
attenuator will cause the attenuator pressure
to increase.
Volume Control Dampers:
ŸAllow for a settling duct between volume
control dampers and attenuators.
ŸDon't site volume control dampers or fittings
too close to attenuators as they can cause a
dramatic increase in attenuator pressure
drop.
Attenuators in relation to bends:
ŸDo ensure attenuator splitters are in the
plane of the bend as shown. Fit turning
vanes it R/W<1.0
ŸDon't use attenuator splitters as shown when
sited close to a bend as the pressure loss
across it will be greater than expected.
Transitions: Ensure symmetrical transitions
from the duct equipment to fan inlet.

ŸPlace a concrete sleeve around the silencer
to increase the acoustic seal between rooms.
For less stringent requirements, pack around
the silencer with a resilient material to affect
a complete seal between the attenuator and
the opening.
ŸWhen trying to achieve very high attenuation
or very low noise levels (e.g. NR20) do not
use an inadequate seal between the silencer
and wall opening.
Isolated walls:
ŸDo fix the silencer to one wall only and place
a flexible or resilient seal on the isolated wall.
ŸDon't bridge the isolated wall to the non-
isolated wall with the silencer fixings.

Louvres on silencer discharge:
o
ŸDo ensure that the splitter orientation is at 90
to the louver orientation and place a spacer
between the silencer and discharge louver.
ŸDon't place a silencer immediately in front of a
louver.
CORRECT INCORRECT
ŸDo place a spacer between the louver and
the silencer and ensure that the splitter
o
orientation is at 90 to the louver orientation.
ŸDon't place a silencer immediately
downstream of a louver.
Fan positions relative to noise sensitive areas:
ŸBest: If fan cannot be relocated, wrap fan
and surrounding ductwork with a noise
barrier material (When wrapping fans pay
particular attention to ensuring there are no
holes at the joins). Allow sufficient overlap in
the wrap to ensure adequate coverage.
Remember that flexible connections will be
the weakest link.
ŸDo not place fans in ceiling spaces directly
above noise sensitive areas.
Flanking transmission:
ŸInstalling the attenuator through or against
the wall minimises the chance of flanking
transmission via the duct system ensuring
the expected performance is achieved.
ŸIf an attenuator is installed as shown, noise
from the fan can bypass the attenuator and
enter the conditioned space. This is known
as flanking transmission and will negatively
impact on the expected attenuator
performance.
Louvers on silencer inlet:

ŸDo use sweeping bends and take offs. Use
long chord turning vanes where possible.
Keep velocities low to reduce airflow
generated noise levels.
ŸDon't use sharp bends or take offs.
Changing direction of airflow:
ŸDo ensure velocities through supply and exhaust
grilled are low by increasing the grille size or
number of grilles. Size ductwork for constant static
pressure to each grille, thus eliminating or
minimissing the need for balancing damper
adjustment (which could / can generate excessive
noise).
ŸDon't allow high velocity air to pass through grilles.
When noise generated by grilles could
cause a problem:
