4. Installation Details.
Health and Safety
Due account should be taken of any obligations
arising from the Health and Safety at Work Act
1974 or relevant codes of practice. In addition
the installation must be carried out in
accordance with the current IEE wiring reg-
ulations and any other relevant British Stand-
ards and Codes of Practice by a qualified install-
er. Isolate all electrical supplies to the heater &
control panel before proceeding.
For your own safety we recommend the use of
personal protective equipment when handling
this air curtain.
Airbloc air curtains are supplied with mounting
brackets pre-fitted, and can be mounted either
as single units, or in multiples, which can be
bolted together to suit various door widths.
The minimum mounting height is 3 metres (See
diagram 2 below).
4.1
Each single air curtain should be supported by
cantilever brackets (not supplied) then fixed
back to the building structure by bolting directly
using suitable support brackets, or by
suspending from above using suitable
steelwork. (See diagram 3, page 6).
4.2
Multiple air curtains should be bolted together
using 3 off M10 set pins, nuts and washers fitted
through the holes provided in the mounting
brackets, then suitable support channels (not
supplied) must be fixed on top of the factory
fitted brackets along the full length of the
assembled air curtains to spread the load.
The assembly can now be fixed back to the
building structure by bolting directly using
suitable support brackets, or suspending from
above using steelwork. (See diagram 4 page 6).
If required, the support channel may be
extended slightly past the ends of the air
curtains to aid fixing.
Note: Where multiple air curtains are fitted
above up and over doors or where
central support is inappropriate, the support
channel should be replaced with channels of a
greater cross section to prevent the assembly
from bending.
4.3 Mounting.
It may be necessary to adjust the position of the
air outlet louvres to provide the correct airflow
across the door opening. This can be done by
first loosening the four locking pins located two
at each end of the louvres (arrowed, Fig. A),
then loosening the intermediate locking Allen
pins (arrowed, Fig. B). The louvres can now be
moved to the desired position and the locking
pins re-tightened.
Note: The AB 225 model has two pairs of
intermediate locking Allen pins, whereas the
AB 175 model only has one pair.
