Maintenance
9.1
Filters
The MVHR should never be operated without filters. However, depending on the actual volume of contaminants in
the environment, the filters (external air and exhaust air from the MVHR) need to be checked and cleaned at least
twice a year and replaced at least on an annual basis. The original external / exhaust air filters contain G4 filter
fibre enclosed in a cardboard frame. Replacement G4 filters are of a frameless moulded construction. Contact de-
tails for authorised servicing by Xpelair approved technicians can be found on the back of this booklet.
9.2
Removing and re-fitting the filters
Disconnect the MVHR from the mains supply.
Remove the Access Hatch by turning it to the left.
Remove the two filters from the MVHR (external air and exhaust air - see picture below).
Insert cleaned or new filters into their correct positions in the MVHR. Please note the clean side of the filter
is placed next to the Heat Exchanger.
o
Filters can be cleaned by gently knocking together to remove dust / dirt.
Replace the Access Hatch.
Switch the mains supply back on.
The MVHR is ready to recommence operation.
9.3
Air Filter Box (optional extra accessory)
The MVHR is fitted with G4 filters as standard. To protect allergy sufferers against environmental pollution, for ex-
ample, it may be useful to install a filter box with finer filters. These filters are designed to offer the longest service
life and lowest pressure loss and are installed in a box immediately after the supply air outlet. Class F5 or F7 panel
filters are available as the filter elements. The fine filters should be checked along with the appliance filters. Please
contact the UK sales office for further details, contact details can be found on the back of this booklet.
Please note:
If the external air is drawn in via a geothermal heat exchanger, a G4 class filter should be installed in the intake
tower.
