OPERATION AND MAINTENANCE (

’

)
SEALED HEPA PERMANENT FILTER
(PP600 AND PP650 POWER UNITS ONLY)
This filter protects the motor and stops small particles from escaping to the outside of the
power unit without the need to replace it. The filter cleans itself by moving up when the power
unit starts, and dropping down when the unit is turned off. Under normal use, there is no need
to maintain this filter. It is possible to remove it to inspect the foam motor filter, or to replace it
if ever it has been damaged (by sharp debris, for example).
REMOVAL AND INSTALLATION OF SEALED HEPA PERMANENT
FILTER (PP600 AND PP650 POWER UNITS ONLY)
To remove:
Remove the pail from the unit. To remove the
permanent filter, use pull tab (
A
) located on edge of
filter to pull and loosen filter from inlet chamber wall.
Squeeze from both sides of the filter to the center of
the housing (see illustration at right). Then, carefully
remove it from the unit.
To reinstall:
Squeeze the filter in order to move it past the inlet
opening (
B
) (see illustration at right). Let the filter bear
against the unit wall by releasing the pressure. Make
sure to place the rigid ring in its groove to ensure
proper sealing.
NOTE: Make sure the filter is installed so that the
pull tab (
A
) is accessible for future filter removal.
