Maintenance and troubleshooting

6.1 

General

The 

exodraft 

Inline fan is designed for prolonged use, and no regular maintenance is required. This specifically applies 

in case it is being used with fuel oil. The Inline fan is designed to make this an easy task. The front part of the venter has 

the motor and impeller mounted on it, and it slides out to provide easy access.

 

The CFI should be inspected periodically (at least once a year) for leakage, and cleaned, if needed.

6.2 

Preparing the inline fan for cleaning

 Referring to fig. 11 below, follow these steps to open the CFI inline fan so it can be cleaned and inspected:

1.  Use removable lifting eyes for disassembly and assembly of motor section. (CFI300 & CFI350)

2.  Remove the four hex nuts holding the motor mounting plate to the housing.

3.  Motor and impeller assembly can be lifted out of the housing. See table listing weights for each model.

4.  Clean the impeller and inside of the housing as needed.

5.  Replace the motor and impeller assembly and tighten hex nuts to secure motor section.

Remove (4) hex nuts before

removing motor/impeller assembly
