BLOWER REPLACEMENT
All electrical work must be properly performed by a qualified electrician per all applicable codes.
Always keep tank openings covered during storage and installation.
When replacing a blower follow the steps below. If relocating the blower, run the electrical supply conduit from the control
panel to the desired blower location. Airline piping from the blower to the FAST® unit may NOT exceed 100 ft [30.5 m] in
total length and must have no more than four elbows. The blower and blower housing must be mounted on a solid base
such as concrete to avoid settling.
Blower Removal
1.
Remove power from the blower assembly by switching the circuit breaker in the control panel to the OFF position.
Also, switch off the circuit breaker in the building’s main service panel. If you plan to keep the blower disconnected
for more than 48 hours, it may be necessary to prevent the discharge of wastewater into the drain field.
Electrical Hazard: Disconnect power before servicing. Failure to do so may result in electrical
shock causing severe bodily injury or death.
2.
Remove blower housing cover by unscrewing the mounting bolts and lifting the lid off the blower housing base.
3.
Remove the motor conduit box cover on the blower motor by unscrewing the two screws securing it to the
conduit box.
4.
Check with an appropriate measuring device to determine if there is power at the electrical wire leads in the
conduit box before proceeding.
5.
If there is no power at the wire leads, disconnect the power leads from the motor leads, noting the connections
for proper re-connection during installation. Insulate and support the wires out of the way of the blower so they
won’t interfere with the blower removal process.
6.
Disconnect the outlet piping of the blower either by disconnecting the union (if used), unscrewing the pipe from
the blower, or cutting a section of the outlet piping. If the piping needs to be cut, be sure to cut the pipe in an
area such that a coupling or union (preferred) can be installed at the cut when the blower is re-installed.
7.
Cover the openings in the pipe where the separation occurred to prevent any foreign material from entering.
8.
Remove the mounting bolts securing the blower flange to the blower housing base.
9.
Lift the blower assembly off the blower housing base.
