Filter system
All THOMAS central vacuum cleaning systems are equipped with a long-term cartridge filter and in addition operate on a cyclone filter principle.
Assembling cartridge filter
The cartridge filter is prefitted at the factory. Please check that the cartridge filter is firmly fitted before starting to use the cleaner.

Important
Under no circumstances is the system to be operated without cartridge filter or when the cartridge filter is damaged.
The exhaust air system must be connected.
No foreign objects must be allowed to get into the exhaust air system.
3.0 Electrical connections
The system may be operated either by radio, control cable or a combination of radio and control cable. Depending on the required mode of operation, the following steps have to be taken.
3.1 Wireless connection ( = central vacuum unit without power control / central vacuum unit with power control)
3.1.1 General instructions
When operating by radio you can teach-in up to 16 sensors and/or repeaters. Should the 17^th sender be taught in this will lead to the overwriting of the 16^th sender.
Teaching in the sender should be carried out on the floor before the system is mounted.
The LCD display shows the mode of operation and the already previously run working hours as basic display (in new status 000h).
In learn and delete mode the system and status information will also be shown.
By turning off the main switch all activated learn and delete functions are interrupted but can be started again if necessary.
3.1.2 Assembly information for central vacuum unit with power control
Install the receiver unit with at least 1 m distance to the hood of the system on the wall next.

If the system is optionally running by radio or control cable the processor will only be completely turned off if all switch contacts are also turned off.
5. To change cartridge filter
Replace or clean the dust bag and cartridge filter at the latest every 6 months or after approx. 25 working hours. This depends on the amount of dust collected in the dust bag.
The extent to which fluff and dust accumulates at the cartridge filter depends on dust type and suctioning and is quite normal.
It has hardly any effect on the suction power.
Do not fail to keep to the stipulated cleaning intervals!
Cleaning/changing the cartridge filters
- Turn off the vacuum cleaner and pull out the mains plug.
- Open the snappers at the vacuum cleaner, take out the dust container and place under the vacuum cleaner.
- Slacken the wing nut and twist it together with the flat washer off from the threaded rod retainer.
- Pull the cartridge filter downwards.
Pointer:
For an easier, cleaner removal of the cartridge filter we would recommend – before removal – pulling a PE dust bag from below over the cartridge filter. This together with the PE dust bag is then to be fully removed downwards.
- Slip the cleaned/new cartridge filter with the flat washer centrally onto the threaded rod retainer up to the top stopper.
- Secure the cartridge filter with the wing nut and the flat washer. Hand-tighten the wing nut.
- Re-fit the emptied dust container to the vacuum cleaner and secure in place by closing the snappers.

Important!
Do never use the vacuum system without a filter or if the filter is damaged!
Note:
The THOMAS filter bag set can be used to dispose of the suctioned material (special accessory).
The vacuum socket of the Centra Clean 18-451 system may not be used in connection with the filter bag!
