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          
regulations and any other relevant British 

 

 

 

Standards and Codes of Practice by a qualified 
installer. 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.
