Starting instructions

• Start the fan unit and ensure that the impeller
rotation is correct. Refer to the rotation sticker on
the fan motor. If the impelle rotation is incorrect,
change two phases (makes no difference which)
with each other (should be done by a qualified
electrician).
• Ensure that the filter cartridges not are damaged.
• Loosen the lower hose to the pressure gauge on
the machine (the pressure gauge for HEPAfilter if
such filter is used). Then turn the damper handle
until the pressure gauge shows 800 Pa. Remount
the hose.

Directions for use

• After some time in operation, open the damper if
needed.
• It is recommended to use ear protection if the filter
unit is used without silencer and without a duct
connected to the outlet.
