Your power unit does not require the assembly of a muffl er. Your CVS
has the muffl er installed internally. You may however desire to exhaust
the air outside. In this case you will need to attach the exhaust adapter.
This will convert the size of the exhaust to the diameter of the central
vacuum pipe.
Refer to page 8 - Image 5
• Place the power unit in order to make the exhaust pipe as short as
possible. Exhausts should be limited to no longer than 16.5ft (5m).
• Keep in mind that you may need space on the sides of your
central unit to be able to access the dirt receptacle.
Refer to page 8 - Image 6
• Align the power unit intake fi tting to the main trunk line projecting from the
wall.
DO NOT GLUE.
Attach the exhaust pipe to the motor exhaust if
exhausting outdoors. Make sure the exhaust pipe is as short as possible.
NOTE:
Mount central power unit at least 12in (30cm) from the ceiling
and any adjacent wall, at least 27.5in (70cm) from the fl oor and within 6ft
(1.8m) of an electrical outlet. Review any local regulations that may apply.

WARNING
Do not block the hood ventilation openings on the top of the central
power unit. Lack of ventilation will cause the motor to overheat.
WARNING
Do not locate the central power unit in a high temperature area where it
is inaccessible for example, an attic or crawl space.
For the ultimate in air control you have model ZCV920H. This model
features a True HEPA fi lter and may be included with your choice of
power unit or can be purchased from an authorized dealer/distributor.
Simply attach the true HEPA fi lter as shown.

SYSTEM TEST
Be certain to comply with local electrical codes and regulations. Plug
the unit into a regular electrical outlet. You are now ready to check the
installation of the unit:
• Be sure the fi lter is properly installed in the power unit.
• Be sure the dirt receptacle is properly secured to the power unit.
• Plug the hose into each inlet valve to be sure the electrical
contacts operate properly.
• Check each inlet valve for air leaks.
• Check each pipe connection for air leaks.

HOW TO USE CENTRAL VACUUM SYSTEM
Your central vacuum system is controlled by a switch on your hose.
Simply insert the hose into the valve and turn the switch to the on position.
This will start the power unit and the fl ow of air.
When you are fi nished, turn the switch on the hose to the off position
and remove the hose from the inlet valve. When unplugging the hose,
hold the inlet cover open for a few seconds to allow suction to decrease
thus, protecting the inlet valve seal.
