Before starting the unit, check the following:
• Confirm that building supply voltage matches the voltage for which the unit is wired.
• Check all piping and wiring penetrations
• Made by contractors for water tightness. All penetrations must be made watertight to prevent water damage to the unit and
building.
• Rotate the fan impeller manually to be sure that it is free to operate. Remove any dirt or debris that may have accumulated
during installation.
• Inspect all fasteners to ensure that none have loosened during shipment.
• Check all electrical connections for proper attachment.
• Check casing and ductwork, if accessible, for obstructions and foreign material that may damage the fan impeller.
Check
• The equipment type and arrangement should be verified as ordered at once when it arrives at the jobsite. When a discrepancy
is found, the local Breeze Sales Representative must be notified immediately so that corrective action may be investigated, also

9. ROUTINE MAINTENANCE
• Regular maintenance is needed each year. The impeller blades require thorough cleaning once in 6 months.
• Before any maintenance work is undertaken:
o Stop fan in accordance to regulations and disconnect all poles from mains supply.
o Wait until impeller is stationary.
o Make sure that a restart is not possible
• Use only original spare parts tested and approved by the manufacturer.
• The following safety notes must be observed when maintaining the machine.
• Replace the ball bearings of the motor whenever the grease utilization period has elapsed in accordance with the maintenance
instructions of the manufacturer.
• The technical maintenance includes periodic cleaning of the surfaces from accumulated dust and dirt.
• Use a soft dry brush or a vacuum cleaner to remove dust.
• Only use usual commercial cleaning material paying attention to the prescribed safety measures and do not use any abrasive
tools (surface protection will be destroyed)..
• Check that the mechanical assembly has been carried out properly
• Remove foreign bodies located in the suction and outflow areas and in the fan space
• Check that the electrical installation has been completed in accordance with regulations
• Does the mains voltage match the motor voltage specified on the rating plate?
• Is the motor protection system set correctly with regard to the motor's nominal current? The setting must be carried out in
accordance with the corresponding details contained on the motor output plate.
• Has the motor been connected correctly in accordance with the wiring diagram? The connection schematic supplied by the
motor suppliers applies for the connection of the motor.
Checks after initial start-up
Check the mechanical connections after initial start-up, especially the joints at the fan.
Checks prior to initial start-up
Proceed with the fan's initial start-up in the following sequence:
Starting up the fan for the first time.
Only put the fan into operation after it has been assembled in accordance with the regulations:
• Put the fan into operation.
• Monitor its correct function (quiet running, vibration, imbalance, power consumption, controllability)
Once the unit has been put into operation, a routine maintenance schedule should be set up to accomplish the following:
• Lubrication of bearings and motor.
• Impeller, casing, bolts and set screws on the entire fan should be checked for tightness.
• Any dirt accumulation on the impeller or in the casing should be removed to prevent unbalance and possible damage.
• Inspect fan impeller and casing looking for fatigue, corrosion or wear.
General Check:
• Too much bearing play?
• Lubricant leaking from the bearings?
• Surface protective coating damaged?
• Attention: Conveyed medium too aggressive?
• Unusual noises during operation?
• Fan output still sufficient for possibly extended or shortened ducting system?
Prior to all servicing work:
• Bring the fan to a halt in the prescribed manner and completely isolate the fan from the mains supply.
• Wait until the rotor has come to a halt.
• Ensure that the machine cannot be switched on again
• Clean the fan
• Clean the suction apertures
• Clean the rotor (if necessary dismantle the protective anti-intrusion fitting)
• Do not overload the motor
• Do not bend the rotor or vanes
• Assemble the protective anti-intrusion fitting.
• Control whether installation is correct:
o Impeller must rotate free
o Annular gap between impeller and casing must be regular.
o Checking direction of rotation is correct.

Transport
• Our products are packed at the factory to suit the respectively agreed mode of transportation. Transport the fan in its original
packaging.
• Fans are protected against damage during shipment. If the unit cannot be installed and operated immediately, precautions need
to be taken to prevent deterioration of the unit during storage. The user assumes responsibility of the fan and accessories while
in storage. The manufacturer will not be responsible for damage during storage. These suggestions are provided solely as a
convenience to the user.
• Only use suitable means of transport, such as pallet trucks or fork-lift trucks or hoist machine.
• If the fan is to be transported by hand, ensure that supporting and carrying loads are kept within reasonable limits for the
personnel involved.
• The fans must not be dropped or thrown. Avoid scratches or rough handling during loading and unloading.
• Parts which have been stacked too high can collapse.
• Avoid a distortion of casing or blades or other damage.
• Danger ! Do not step under hanging loads.
12. TRANSPORT AND STORAGE
Storage
• Store the unit in the manufacturer’s original packaging box in a dry closed ventilated premise with temperature range from +5˚С
up to +40˚С and relative humidity up to 85%.
•Store the fan in a dry, weather-protected location in its original packaging or protect it from the effects of dirt and the weather
until final assembly. Storage environment must not contain aggressive vapours and chemical mixtures provoking corrosion,
insulation and sealing deformation.
•Rotate fan impeller monthly and purge bearings once every three months.
•If storage of fan is in a humid, dusty or corrosive atmosphere, rotate the fan and purge the bearings once a month. Improper
storage which results in damage to the fan will void the warranty.
•Avoid lengthy storage periods (a maximum of one year is recommended) and check that the motor bearing assembly is in good
functional order prior to fitting. With storage times of more than 1 year, please check the bearings on soft running before
installation (turn by hand).
Change of motor impeller:
• Disconnect electrical supply in function box.
• Unscrew motor mounting and pull out of the casing complete with motor, impeller.
• Install a new motor impeller complete with motor mounting in casing.
• Assembly fan.
•Control whether installation is correct:
o Motor and impeller must rotate freely
direction of rotation is correct. o Control whether
o Install maintenance cover if have.
o The gap between impeller and casing must be regular.
•Install the fan into air duct.
•Push into operation after repaired.
•Connect electric supply of motor.
