Replacing HEPA filters process:

Unclip the top two toggle clamps, removing the security split pins in advance. 

Remove the Head assembly and place in a safe area. Unclip the lower two 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.
