4.0 FITTING CLAMPS
For installation into the duct clamp, push the 2 pre-cut lengths of
ducting firmly into the clamp at opposite ends.
Double check the
squareness of the cut ducting. Failing to do so may cause air
leakage.
The centre joint of the duct lengths should be located on the centre
flange of the clamp.
Ensure the ducting is fully pressed into the
clamp to create an air tight seal. Failing to do so may cause air
leakage.
Press the fixings tabs down until they lock in place.
5.0 FITTING DUCT BANDING
For installation onto a solid surface, suitable duct banding must be used
to support both the rectangular and circular ducting and should be
fitted every 1m. When fitting the bands at the fixing clamps the raised
tabs provided will act as an installation guide. Nuaire recommend
the use of PVC coated galvanised banding available under item code
PVCBAND.
As an alternative, uncoated galvanised banding may also be used.
Note, in both cases, if banding is used on the duct itself and not at the
fixing clamp then care should be taken to ensure the banding does not
cut into the surface is this may cause damage and ultimately lead to
leakage.
