BAGHOUSE ASSEMBLY / INSTALLATION
1. Foundation loads and structural orientation as per drawing 2243-4545-MC-127.
Foundations to be designed by installer. Place structural legs on foundation pads. Bolt
the lower bracing clips to the legs using the angle clips. Bolt the top structural channels to
the legs making sure the support is free standing. Anchor (anchors by installer) and grout
the baghouse support structure to the foundations.
2. See drawing 2243-4545-MC-127 for orientation of the lower hopper. Apply joint sealing
compound to all flanges and joints in the assembly of the hopper. Lift the gasketed
hopper into the correct position sitting on top of the support channels. After the bottom
hopper are in place and the flange gaskets are applied, the top dust collector assembly
may be picked up by the lifting lugs. Lift the dust collector into place and set it on the
structural support and the hopper. Bolt the bottom flange of the dust collector to the
hopper and the support channels. Position holes with drift pins as required.
3. Install all walkways and ladders per the general arrangement drawing. If possible, install
the walkways and ladders to the dust collector before lifting the dust collector into place.
4. Apply gasket and sealant to the top flange of the rotary valve and bolt the rotary valve to
the flange at bottom of the hopper.
5. Connect clean dry 80-100 psig compressed air (dew point less than -20 F) to the air
coupling at the air pipe manifold. A filter, pressure regulator should be installed in the
supply line to “fine-tune” the air cleaning system.
