DISASSEMBLY INSTRUCTIONS
PLASTEC JET SERIES
Before beginning these instructions, place this fan on a bench or table top that can
support its weight.
1) Disconnect the fan from its power source.
2) Open the switch box. Take note of the wire positions before removing them from the
wiring terminal.
3) Unscrew the plastic locknut from the liquid tight fitting on top of the switch box and the
one from the face of the weather cover.
4) Gently pull the conduit and cable out of the top of the switch box and pull the conduit off
the cable.
5) Push a short length of cable back into the weather cover. This provides slack for lifting
the weather cover off the manifold.
6) Remove the six or eight Phillips head screws from the base ring of the weather cover.
7) Lift the weather cover up and over the top of the manifold, being careful not to damage
the cable.
8) If the motor is being replaced, be sure to retrieve the cable and strain relief connector
from the wiring box. Take note of the orientation of the wiring positions before removing
the cable.
9) Take note of the orientation of the motor as it sits in the fan body. This is important for
the reassembly procedure.
10) Remove eight Torx head screws from the motor plate. Lift the motor assembly out of
the fan body. Stand on the cooling fan end of the motor. Refer to step #3 of the utility
blower disassembly sheet.
