Locate the two low-voltage wires near the main
pipe. Remove the insulation from the low-volt
wire. Insert the low-volt wire into the spring-
loaded low-volt connectors (refer to figure 3).
Be certain you comply with your local electrical
codes and regulations.
The power cable has a three prong style
connector on one end. This connector must be
plugged into the matching connector on the
power unit. Plug the other end of the power
cable into the wall electrical outlet.
You are now ready to check the installation of
the unit:
Plug the hose into each inlet valve to
•
be sure the electrical contacts operate
properly.
Check the inlet valve for air leaks.
•
Check each pipe connection for air leaks.
•
Be sure the dirt receptacle is properly
•
secured to the power unit.
Be sure the filter is properly installed in the
•
power unit.
Your cleaning system is ready to use.
Your central vacuum
system starts and
stops automatically.
To turn the system on,
plug the hose into a
wall inlet valve. To turn
it off, remove the hose
from the valve (refer to
figure 4).
Electrical Fault Protection
The central vacuum system employs features
that monitor the following operating levels:
AC voltage, current draw and circuit board
temperature. If the voltage is below or above
standard operating voltage, high current
draw or locked rotor, the power unit will not
operate. In this case the LED next to the On/
Off button will blink or go out until the problem
ceases. In the event any one of these problems
happening, make sure all low-volt switches
are in the OFF position, then press the on/off
button, unplug hose, or wait for temperature
to lower. If problems persist, contact the
authorized service center nearest you.
In the case of power failure, the power unit
will return to its previous state when power
returns. For example, if a hose is plugged in
with the hose switch on, or a straight air hose
is plugged into a wall valve, then the power unit
will turn back on. If the power unit was turned
on at the unit prior to power loss then the unit
will not turn back on.
Inlet valves
Plugging the hose into an inlet valve complete
a low-voltage electrical circuit which activates
a relay and turns on the power unit. To turn off
the power unit, unplug the hose from the inlet.
When unplugging the hose, hold the inlet cover
open for a few seconds to allow suction to
decrease and protect the inner seal.
An obstruction in the inlet valve may cause the
power unit to continue to run after the hose
has been removed from the inlet. To shut down
