Troubleshooting
Your Omnitec Design machine is designed and engineered to provide years of trouble free service. Occasionally problems
occur. Here are some helpful tips and solutions
The machine does not start
1.
Check that the unit is plugged in and there is 115VAC available (or 230VAC for the 230VAC unit). Select either LOW or
HIGH speed to turn the machine on. If the red indicator light comes on, power is coming to the unit from the outlet.
2.
Call Omnitec technical support to troubleshoot further.
The machine just hums when turned on
1.
Unplug the unit.
2.
Remove the HEPA filter and push the blower wheel by hand. If it does not move freely or if you hear a grinding/
scrapping noise as you spin it, then the blower wheel is touching the side of the blower housing. This may be due to an impact
of some kind and the motor mounts have been bent. Remove the motor/blower assembly and replaced the bent motor
mounts.
3.
If the blower spins freely, check the capacitor. With the HEPA filter still removed from the machine, insure that the
wiring connected to the capacitor is plugged in and not broken. Re-plug the unit into the power outlet keeping the switch in
the OFF position. Then push the blower wheel and as it is spinning, turn the speed selector switch to HIGH. If the machine
keeps running, the capacitor needs to be replaced.
The machine will run for a few minutes then turn off
1.
The machine must have a HEPA filter installed to operate properly. If you are trying to run it without a filter in place,
the motor will overheat within a few minutes and the thermal overload will engage and shut it down. Let the motor cool off
for 30 minutes, install the filter and try running the machine again.
2.
If the filter is in place and the machine still shuts off after a few minutes then the motor is faulty. Replace the motor.
The machine vibrates excessively when running
1.
This is an indication that the motor bearings are worn out. If the machine continues running, at this point the vibration
will cause the center hub of the blower wheel to separate from the wheel requiring replacement of both the motor and
blower. Replace the motor.
2.
If the machine does require electrical servicing of the motor or switches the following page contains a wiring diagram
to aid in repair or troubleshooting.
