WARNING: Ensure Personal Protective Equipment is worn
while carrying out this procedure.
WARNING: Ensure that all services are turned off and locked
out after cleaning the booth.
1. Clean the booth base and walls to avoid unnecessary contact with the
powder.
2. Relieve all air pressure in the system. This can be done by turning off
the air supply and operating the pulsing. Or by releasing the pressure
safety valve attached to the air manifold.
3. Lock out and disconnect services to the booth.
4. With the exhaust fan running, thoroughly clean the booth and remove
all powder from the hopper.
5. Remove the plenum chamber, by unbolting all the fixings. To remove
the plenum it may be necessary to use a larger screwdriver to lever the
plenum from the hopper.
6. Discard the damaged fluidising plate.
7. Check the fitting of the new fluidising plate. Check the alignment of the
fixing holes, if necessary drill holes to suit.
NOTE: The fluidising plate is fitted smooth side up.
8. The fluidising plate is sealed using an acrylic sealant. On the plenum
make a small bead of sealant around the inside of the fixing holes.
Place the fluidplate, smooth side uppermost on the plenum. Make a
second small bead of sealant again around the inside of the fixing
holes on the upper side of the fluid plate. DO NOT use a silicone
sealant.
9. Offer the plenum up to the bottom of the hopper and secure with the
fixing bolts. Tighten the bolts firmly but do not overtighten as this may
damage the fluidplate. Remove any excess sealant.
3. Fluid Bed Replacement
