Dear customer please find below some information on how to maintain your PAUL MVHR system.

When to clean or change a filter:

MVHR filters should be maintained regularly, every 3 to 6 months, in order to maintain the air flows and keep the energy use to a minimum. As the PAUL novus system is volume flow constant, soiled filters, pressure changes and other factors will neither cause an inbalance nor reduced ventilation, which is an integral part of a high quality system. Clogged up filters will therefore result in an increased energy use as the MVHR has to work against the resistance of the filters, in order to keep the air flow at the same level. If the filter medium is fully covered in dust, it is high time to clean or change the filters. Another indication that the filters need to be checked is an increase in fan noise.

In most cases filters can be cleaned out with a vacuum cleaner (with brush attachment). If the filter cannot be cleaned e.g. when covered in grease or soot, it needs to be replaced. All filters should be completely changed over at least once a year.

How to change the filter:
1. Switch MVHR to unoccupied mode.

2. Remove the red maintenance covers of the climos unit and remove the 2 rectangular filter covers.
3. Take out the filters by pulling on the strap (please be careful not to touch or inhale the dust) and place the soiled filters in a bin liner, seal and discard
4. Insert clean filter with the arrow mark on the filter pointing towards the middle of the MVHR (in direction of air flow).
5. Replace all covers and switch MVHR back to normal operation (‘Auto’ or fan speed 2 or 1)
6. Reset filter timer on the touch screen (menu/settings/filter: tick the box and press enter until filter timer has been reset, then return to the home screen)

General maintenance information:

System should be cleaned out every 2-3 years. Please refer to the manual for how to take out the heat exchanger. It should be rinsed out with washing up liquid and hot water, ideally in a bath tub or shower area. Please be careful when taking out the heat exchanger as it can contain large amounts of water especially during winter. Please don’t insert tools or similar into the tube of the heat exchanger or forcefully brush it as can lead to damage. After cleaning the heat exchanger, it should be inserted in the same way with the black tray underneath the label visible.
