INSTALLATION OF CASSETTAIR CEILING HEATER 

 

The Cassettair ceiling heater is designed to be recessed within ceiling voids or 
bulkheads within a building and located horizontally.  It must not be installed 
outside of the building. 

 
 

 

Location  

 

Cassettair ceiling heaters may be installed anywhere that requires instant, discreet and 
trouble-free  heating.  Cassettair  ceiling  heaters  should  be  mounted  within  its  height 
specification  of  1.8m  to  3.5m  maximum  (from  floor  level  to  the  underside  of  the 
unit/grille).   
Cassettair  has  been  designed  with  the  air 
inlet  and  discharge  located  on  the  same 
profiled  face  of  the  grille.    Using  high 
performance centrifugal fans, air entering the 
unit  passes  over  the  heating  coil  and  is 
immediately  redistributed  through  the  outlet 
grille. 
 
 

  

Ceiling Suspension 

 

Cassettair  can  be  mounted  either  before  or 
after  the  ceiling  suspended  grid  system  is 
installed.  The  ceiling  heater  has  been 
designed  to  easily  fit  universal  suspended 
ceiling grid systems. Ensure there is sufficient 
height  clearance  in  the  ceiling  void  for  the 
heater  to  be  fitted,  for  dimensional  details 
refer to Figure 1. 

 

Cassettair  is  supplied  with  two  mounting 
strips (A). 
Fit  and  secure  four  M10  threaded  rods  and 
locking  nuts  into  each  of  the  mounting  strip 
slots.  These  strips  may  be  suspended 
together with suitable Unistrut® (B).  

 

Note:  threaded  rod,  locking  nuts  and 
Unistrut®  are  not  supplied.  For  access, 
inspection  and  maintenance  ensure  suitable 
access is available. 

 
 
 

Ensure  each  of  the  threaded  rods  are 
secured  on  to  a  suitable  structure  that  can 
support the 36kg weight of the unit.   

 

Carefully  lift  the  Cassettair  into  place  by 
hooking  the  cassette  heater  hanging  strips 
onto the mounting strips (A).
