European Machinery Directive 2006/42/Ec - Woods 905989 Safety Installation And Maintenance Instructions

21. EUROPEAN MACHINERY DIRECTIVE 2006/42/EC

1.7.4.2 CONTENTS OF THE INSTRUCTIONS CLAUSE C)
Please see a typical example of an EC declaration of conformity certificate (below), which shows particulars of the machinery
offered.
CLAUSES G) AND H)
Fans must not be operated above their maximum indicated speed or run where the fan is operating in a stalled condition.
Fans must also not be run in reverse unless specific advice is sought from Woods Air Movement.
CLAUSES I) AND J)
Fans must be isolated from support structures by means of anti-vibration mounts and from adjacent ductwork by flexible
connections.
CLAUSE K)
Care must be taken when installing fans to ensure that the product orientation is correct in relation to direction arrows which
indicate direction of air movement and impeller rotation direction. Where two-stage fans are shipped as two separate fan units,
please refer to the appropriate two-stage assembly drawing, which is available on request.
Also see figure 1 within this document.
Herewith we declare that the air movement equipment designated below, on the basis of its design and construction, in the
form brought on to the market by us, is in accordance with the relevant health and safety requirements of the EC Council
directives on Machinery and Electromagnetic Compatibility. If alterations are made to the machinery without prior
consultations with us, this declaration becomes invalid. We further declare that the equipment identified below may be
intended to be assembled with other equipment/machines to constitute machinery, which shall not be put into service until
the assembled machinery has been declared in conformity with the provisions of these EC Council directives.

Notes:
(1) Fläkt Woods fans are driven by AC induction motors which are inherently compliant if supplied with a truly sinusoidal AC supply.
Where the fan motor is supplied via an inverter or other electronic control, verification of its compatibility together with cabling should be
sought from the control supplier.
(2) For a complete list of applied standards and technical specifications see Fläkt Woods documentation.
(3) Where no relevant harmonised standards exist.

2. Examine motor cooling fins
3. Examine impeller for dirt build-up or
3
any physical damage
4. Check condition and tautness of fan safety
3
support chains / harnesses / ropes (if fitted)
5. Examine and operate vibration sensors
3
(if fitted), and temperature sensors
(if fitted)
6. Examine condition of safety guards (if fitted)
3
and associated fixings
7. Check operation of anti-condensation
3
heaters (if fitted)
8. inspect the condition of the packing located

Comments
Months
Remove any debris that may have accumulated round or on the
guard surface.
Remove any material or dirt which has build-up between the
motor cooling fins.
Remove any build-up of dirt. Ensure impeller is secure.
Replace impeller if it is damaged.
Clean and inspect safety supports. Replace if there is any
deterioration / corrosion detected.
Check operation using built-in sensor test features or dummy
signals. Check that the fan is automatically switched off, or that
a warning indication is provided, when the sensors / switches
indicates a fault.
Clean safety guards. Replace if there are any signs of excessive
corrosion or damage
Switch off power to the motor. Check that the anti-condensation
heater is energised (i.e. it is drawing current).
Replace the 130mm Duramid seal if it is damaged
Ensure that the gap between the impeller blade ends and the
fan duct is even and adequate. If in doubt, please contact Woods
3
Air Movement for advice related blade tip gap. Ensure that the
impeller blades are secure. Blade angle must not be changed
before contacting Woods Air Movement for advice.
It is essential to confirm that all fixings are properly fitted, are
tight, and are fully driven home (see Paragraph 17.1). If in doubt,
3
please contact Woods Air Movement for advice related to the
torque value of a particular fixing.
It is essential to confirm that all fixings are properly fitted, are
3
tight, and are fully driven home (see Paragraph 17.1) If in doubt
about the torque of a fixing contact Fläkt Woods Ltd for advice.
Check freedom of movement. Tighten anti-vibration mount
3
fixings if necessary.
Ensure voltage and full load current are as specified on the
3
motor nameplate
3
Treat any areas of damage with suitable anti-corrosion paint.
3
Check requirement in accordance with paragraph 17.2
Check security and condition of all wiring
3
(including the earth).
Vibration levels, whilst the fan is operating, should not be
excessive. If levels are seen to have increased since the previous
3
inspection, the fan must not be operated until the root cause
has been identified and rectified.
