be seen from the side of the operator (the arrow is by the unit´s door) and that the arrow always
points towards the heat recovery exchanger!
The unit is supplied with filter cassette labels unattached. Attach the relevant identification labels
●
near both filters (e.g. on respective unit door).
Unpack and install air filters last, immediately before putting the unit into service to avoid their
contamination.
Use original filter cassettes only! If different cassettes were used, the manufacturer cannot
guarantee their proper function!
Record the date of installing filters appropriately in e.g. the operational logbook.

Installing, connecting and filling liquid manometers
Liquid manometers are a separately supplied accessory. Manometers are compulsory for hygienic
Ü
units in compliance with VDI 6022.
Manometers are used for measuring the pressure loss of air filters. During installation follow the
·
visual instructions supplied with this optional accessory. After installation level the manometers
horizontally.
·
Connect the manometers to collection points on the unit´s surface using tubes. Connect the tube
to the top of the manometer and run it to the metal bushing on the unit´s surface (also see a
separate manometer installation manual). The tube must always connect two matching connection
points identified by symbols "+" and "F+" and "-" and "F-" (cannot be combined). Make sure that
tubes from just one filter are connected to the manometer.
Attach the relevant label near each manometer. Fill out the boxes with the filter grade and record
·
the flow rates and pressure losses of the clean filter (initial pressure loss) and when clogged (final
pressure loss) using data from the table below; the values must be adjusted on the basis on actual
air flow rates through the unit. The unattached label without information filled out is included.
