Filtration System - Kerstar KV 20 Operating Instructions Manual

FILTRATION SySTEM

This is a Type H Vacuum Cleaner. It is fitted with 3 stages of filtration on the negative pressure side of the motor
(that is before the motor, so that the motor always receives clean filtered air).
1st Stage - K4 Disposable Microfibre Bag
2nd Stage - High Efficiency Filter Assembly specially for Type H cartridges
3rd Stage - Type H HEPA (High Efficiency Particulate Air) Cartridge Filter
Also known as the Absolute or Essential Filter.
KV20–50H HEPA Filter part no. K27.03.04.
Note: The HEPA cartridge filter fitted to Kerstar KV20–50 Type H models has a very large
surface area compared to other models available and will therefore give improved performance
and a greatly increased filter life.
Access to the Microfibre Bag and Filtration System
a) To remove the motor head and HEPA cartridge unit, unclip the LOWER set of clips. Ensure that the clips
are hinged clear of the rim of the HEPA unit. Lift the motor head and HEPA unit clear of the canister.
b) To refit the motor head and HEPA unit align the head so that the cable entry lies directly opposite the hose
entry on the canister. Locate the clips over the rim of the HEPA unit and firmly press down both clips until
they have locked into position.
N o t e : T h e u p p e r
have a lock-down device to prevent the separation of the motor head from the HEPA unit.
Only authorised and trained personnel should separate the motor head from the HEPA unit.
