Installation instruction
Uniguard 8
Hydraulic diameter ( )
Example of installation at
sources of interference:
- fan
- damper
- silencer
- battery
- air handling unit
- duct bend
- duct branching
- duct narrowing or expansion
Where large temperature variations
occur, e.g. on outdoor
locations or in areas subject to
outside temperatures (roof,
attics), the Uniguard should be
insulated, see para 8.
Note
the foot’s shape of an arrow, which shall be installed towards the
air flow direction
.
Example of location after
change of duct direction.
Example of location before

Mounting and positioning
The Uniguard should be installed according to the
drawing below. The Uniguard can be installed on any
side of the duct.
We recommend that the Uniguard is mounted at an
equal distance from sources of interferance, and similar
to the siting of flow monitors.
A distance of 3 times the duct hydraulic diameter should
be left before a source of interferance, and 5 times the
hydraulic diameter after
.
