Replacing HEPA Filters Process
HEPA filter INLET (see figure 1)
Unclip the top three toggle clamps, removing the security split pins in advance. Remove the Head assembly and place in a
safe area. Unclip the lower three toggle clamps and remove the Interceptor assembly from the drum assembly, and place the
Interceptor on a good level working surface.
Unscrew the 6, M5 x 10 screws on the underside of the Interceptor assembly which will expose the HEPA filter.
Remove the contaminated HEPA filter and place in a suitably impervious plastic bag and dispose of in accordance with current
regulations. Replace the HEPA filter with an identical approved part (ensure plastic filter grid that locates into the hole in the
metalwork is not thrown away with HEPA filter).
Re-assemble the Interceptor assembly in reverse order. If the seal between the upper and lower metal parts of the Interceptor
assembly is damaged, replace with a manufacturer approved seal material (there must be NO gap in the circular seal).
Re-assemble the machine in reverse order. (Screw torque 2.5Nm). Ensure new split pins are fitted
and legs opened
During this process please look carefully at all seals between mating parts and check for any damage.
If seals have been damaged, please contact the machine manufacturer to obtain an approved replacement part.
