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.
Checks after initial start-up
Check the mechanical connections after initial start-up, especially the joints at the fan.
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)..
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.
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?
Clean fan:
•
Remove louver, orifice and impeller.
•
Remove the fan casing in the wooden frame.
•
Clean dirt on fan casing. Wash and clean louver, orifice.
•
Clean impeller.
o Do not flood motor.
o Do not bend impeller, blades.
•
Using a cloth dampened with kitchen detergent, remove any
dir from fan body, wipe dry with new cloth.
•
Assembly fan.
•
Control whether installation is correct:
o Motor impeller must rotate free
o The gap between impeller and casing must be regular.
o Checking direction of rotation is correct.
•
Install the fan into air duct.
•
Connect electric supply of motor.
