Hi all

I have a quick question regarding a cassette style air con unit in an office. When it was installed, the engineer showed the staff how to clean the filters. However, no-one knows how regularly this should be done. I've tried a search to see if I can find anything in any legislation, as I understand that legislation regarding air conditioning has recently come intoforce, but cannot find anything.


I have only just started in this role within the company, and no-one seems to know where any records relationg to the unit are.


Thanks in advance.

As far as I am aware there is no legislative control for the cleaning of filters in ceiling cassettes or wall mounted VRV/VRF type units. Refrigerant yes, loss of gas yes but cleaning I am not aware of (from a prescriptive stance).

Generally the filters blades and central intake are all that require cleaning. It takes just a few moments to run a vacuum cleaner nozzle over it, and perhaps this could be undertaken by the cleaning company (if you have one), saves staff having to get mucky, saves you training them, and best of all you have eliminated work at height:-)

I can't suggest frequency rates because I don't know how dusty you are there - and how many employees you have. Open doors, dirty carpets, but above all else it will be skin particulates that create the most clogging. When you next get changed and the sun is shining through the window watch just how much dust (skin) you make when you get undressed.

Hi CFT - thanks for your reply. You have echoed my own thoughts, but I felt it best to double check.

I've not been on here for a while now, but historically, I remember that I usually got some sterling advice whenever I did. I 've had to re-register now, as I have changed jobs and couldn't remember my password!

Finally, can anyone tell me where I can find a full copy of the legislation and ACOPs?

Sorry I should have given you a reference point.

Follow this one; http://www.acrib.org.uk/LX114H44326

It is fairly comprehensive including F-gas regs.

you could start with Approved Document F, then from there and HSG 202 (which seems unavailable in the HSE website) . Both documents point you towards the CIBSE document TM26:2000 Hygiene Ventilation of Office Ventilation Ductwork, which should give you some guidance. Info in above post is correct, have to make it suitable and sufficient in order to not cause any problems for workers, no dust build-up etc and is related to risk assessment of the dust etc being created and how it needs to be removed.

Hi all

Thank you very much - your help is really appreciated.

Thanks where itis due - I remember when I used to use these forums before, that there were a lot of people that would pop in and ask a question, then never be heard of again (and never say thanks).

Nick.

Hi Nick,

The reference to new legislation is probably about mandatory inspections now required on aircon units over 12Kw
