Troubleshooting The System - Dirt Devil CV1800 Operating Instructions Manual

& CV2600
General Power Unit
Maintenance
The simple care and maintenance
instructions included here will
help ensure trouble-free use of the
central vacuum system.
• Do not place objects on top of the
power unit. The motor could
overheat.
• Do not allow the motor to remain
"on" unless a hose is connected or
an inlet valve is open. If airflow is
not permitted to flow through fan
blades, motor damage may occur.
• Do not operate without a filter in
place.
• Empty the dirt canister when it is
1/2 - 2/3 full.
• Change the filter cartridge once a
year.
• The power unit does not require
any lubrication.
• The exterior of the power unit can
be wiped with a clean, dry cloth.
Do not use liquid cleaners or water
as an electrical shock may occur.
• For additional service contact a
qualified service person.
Troubleshooting
the System
Motor Fails to Turn On:
• Check the main fuse or circuit
breaker at the main power supply
panel of your home. Reset breaker
or replace fuses if necessary.
• Check the Power unit reset button
located above the power cord.
Pressing the button should restore
operation.
• If the circuit protector continues to
trip off after a short period of time,
the motor brushes may be worn
out. Call a qualified service person
for service.
Loss of Vacuum
If the system shows a loss of vacuum
power, check the following:
• The dirt receptacle and filter may
need cleaned – follow instructions
in this guide.
• The hose may be clogged – To
check if there is an obstruction,
unplug the hose and insert an
object that is smaller then the
diameter of the hose (A butter knife
works well). Pass the object
completely through the hose, if it
stops that will indicate where the
obstruction is located. A dry garden
hose can be inserted into the hose
to help push obstruction through.
