Maintenance tips – what you can do yourself
There are a few simpler things you can do yourself to improve your ventilation:
FILTERS
- Both the supply and exhaust air filters should be replaced at least twice a year or in accordance with the supplier’s instructions.
- You should vacuum the filters between filter replacements as well, such as when spring cleaning. Be sure to vacuum carefully to avoid damaging the filters.
- It is very important that the filters are fitted correctly. Check the maintenance instructions from the supplier.
GREASE FILTER (kitchen extractor fan)
- The grease filter is most often found in a plastic holder under the extractor hood. The holder can also be of metal and sit in a frame.
- There are several reasons why it is important to wash the grease filter often. Primarily to prevent grease particles from coming loose from the top of the filter and collecting in the extractor ducting, which in the case of a hob fire can cause the flames to spread more quickly. It is also important to keep it clean so that the grease that is collected does not get old and start to smell.
- Washing-up liquid can be used for all types of grease filter. Dishwasher detergent, on the other hand, can discolour aluminium filter holders.
HEAT EXCHANGER
- You should not take it upon yourself to clean a heat exchanger with an integrated motor (such as a rotary heat exchanger).
- A plate heat exchanger with manual recovery should be cleaned twice a year using hot water and a mild detergent. You can use a shower for good results – just remember to protect the bathtub or bathroom floor so that the heat exchanger does not scratch them.
- Be careful when handling the heat exchanger to avoid damaging the plates.
- Be sure to refit the heat exchanger just as it was when you removed it.
FANS
- Fans should be cleaned once a year, and they must be removed to be cleaned.
- Fans are best cleaned using, for example, a small brush.
- Balancing weights must not be moved during cleaning. NB: You must not spray water on fans!
AIR VENTS
- Air vents are found both indoors and outdoors and should be cleaned twice a year.
- An air vent can be cleaned by removing the vent (pull it straight out) and rinsing it with hot water. NB: Do not alter the air vent’s setting!
WORTH KEEPING IN MIND:
- Keep and follow the instructions for use and maintenance for the house. Remember to hand them over to the next owner.
- Be sure to follow the supplier’s maintenance instructions when you buy new equipment.
- Keep a logbook of everything that is serviced or repaired in the system and when. This can also help the master chimney sweep or service engineer if something goes wrong.
- Engage a professional to inspect the ventilation system in your house at regular intervals.
- For further information – or help cleaning your ventilation – feel free to contact your chimney sweep!
