Safety Practices for Users and Installers of

CA and CF,

provides

Receiving

All CA/CF blowers are shipped fully assembled. This
helps insure that the fan arrives at the jobsite undamaged
and that all components are present. In addition, this gives
the assembler/disassembler the opportunity to view the fan
in its completed state. The fan should be carefully
inspected and these instructions understood before
attempting disassembly.

Disassembly

Mark location of inlet cone(s) and remove from fan by
removing attachment bolts around perimeter of cone. Cone
is sealed to unit with gasket material, so care should be
taken to avoid damaging the gasket.

To remove top of fan housing, simply remove bolts/nuts in
flange around perimeter of fan. Several bolts should remain
in place until lifting device is attached to prevent the remov­able portion from moving unexpectedly.

NOTE

If wheel and/or shaft was removed from the fan,
field vibration balancing should be performed.
Failure to insure proper balance will void factory
warranty.

If it is necessary to remove the wheel and/or shaft, please
refer to pages 6 and 7 of the CA/CF/CP Installation, Opera­tion, and Maintenance manual.

Assembly

• If the wheel and/or shaft was removed, reinstall the shaft
and bearing assembly in the original location. Refer to
the CA/CF/CP Installation, Operation, and Maintenance
manual.

• Replace housing top in original location. Gasket mate­rial or caulk may be used to seal housing if desired.

• Replace all bolts and tighten.

• Replace inlet cone with original bolts, but do not tighten.

• Rotate wheel to insure even clearance between inlet
cone and wheel.

• Center inlet cone as needed and tighten bolts.
