11. Position motor on pedestal and secure loosely by replacing the 4 nuts, bolts and
washers.
12. Locate motor key into keyway on motor shaft.
13. Push motor shaft spacer onto motor shaft.
14. Align keyway of impeller hub onto key and slide impeller onto motor shaft.
15. Replace hub retaining washer and shakeproof washer. Apply thread lock to motor
end shaft bolt and replace bolt, ensuring impellor is pushed back onto spacer.
16. Apply thread locks to grub screws holding hub and tighten into place.
17. Locate impeller, according to the dimension taken during removal, by moving
motor along pedestal, ensuring motor remains square to fan case.
18. If the measurement was taken from impeller back plate to fan case, adjust to
suit and tighten motor fixing fasteners through pedestal and motor feet. Replace
inlet eye, using a bead of sealant between the plate and fan case and replace
outer circle of bolts.
19. If the measurement was taken from inlet eye to impeller front plate, then replace
inlet eye, using a bead of sealant between the plate and fan case and replace
outer circle of bolts. Adjust impeller to suit and tighten motor fixing fasteners
through pedestal and motor feet.
20. If a measurement was not taken, then replace inlet eye, using a bead of sealant
between the plate and fan case and replace outer circle of bolts. Adjust impeller
so that there is approximately 2 mm clearance between inlet eye and front of
impeller and tighten motor fixing fasteners through pedestal and motor feet. For
ignition minimising fans the minimum clearance must be
>
1% of the relevant
contact diameter.
21. Rotate impeller by hand, adjusting where necessary, to ensure that impeller
runs freely.
Replacing fan assembly:
If changing fan assembly for a different type, e.g. K5 to K7, ensure the
associated fan mounting plate and fan support channels are used. If required,
any necessary electrical items should be resized.
1. Lift fan assembly into position.
2. Loosely replace securing bolts.
3. Ensure fan assembly is correctly positioned, then tighten bolts.
4. Connect electrical cable to motor.
5. Feed motor cable through front panel and reconnect electrical cables to terminal
box.
6. Replace fan section top panel.
Before replacing top panel, apply 5 mm bead of sealing compound along
each side of fixing holes.
7. Replace side access cover.
Before replacing side access cover, apply 5 mm bead of sealing compound
along each side of fixing holes.
8. Switch on electric power.
9. Ensure correct fan rotation (refer to fan rotation label located on rear panel of
fan section).
