Oreck 4478801 Air Cleaner User Manual


 
General Parts Replacement
All leads must be connected to the new board properly. The HV power line must be
isolated and properly routed. Two insulator sheets must be in position and all wiring must
be captured to prevent contact with rotating elements. A wiring diagram is included in the
service manual for your use.
3. The new board may now be reinstalled in
the housing by sliding it back into position.
The housing has two board reference ribs
molded in the bottom that hold the board
in position. Position the board between
the side wall and the reference ribs. You
may need to hold the board in place
before and during installation of the power
supply cover.
ROTATING ELEMENT WARNING - Unit has a rotating blower wheel and cooling
fan to circulate air and keep the unit cool. When servicing the unit and repairing
the unit always insure that you keep objects and internal electrical wiring away
from the rotating elements. Failure to allow for proper clearance for rotating
members can cause electric shock, personal injury or property damage.
4. The power supply cover may now be
reinstalled. Check wiring to insure it is
routed properly and cannot contact motor
fan and is properly isolated. Install the
power supply cover by placing the cover
locator tabs into the cabinet at an angle
while rotating it into place. The locking
snap should engage when in the final
position.
EXTREME HIGH VOLTAGE WARNING - This equipment is supplied with high
voltage from a standard electrical wall socket. That voltage is transformed to a 24V
signal that is then amplified to over 6000 VDC. In working with the equipment you
must always know the voltage level for the equipment and wiring. Attempting to
measure or work with the 6000 VDC power without using the proper high voltage
probe can cause electrical shock, personal injury or property damage. Measuring
high voltage without the proper meter and probe will potentially damage the volt meter.
