  Fitting of the Grille

 

 

The grille consists of a profile face with two fixed 
hinge mount brackets. 
 
Before  lifting  the  recessed  grille  into  position, 
locate the two hinge mount brackets fitted on the 
grille  frame.    With  both  mount  brackets  facing 
upwards towards the cassette heater, raise grille 
to the two spring loaded hinges.  
 
Push  one  spring  loaded  hinge,  as  indicated  on 
the  insert,  and  locate  hinge  pin  into  the 
appropriate  mount  bracket.  Repeat  with  other 
spring  loaded  hinge  and  affix  grille  to  cassette 
heater. 
 
 
 
 
 
Once the above is complete the recessed hinged 
grille can positioned into place. 
 
 
 
 
 
 

 

 
Fasten the recessed grille by twisting and locking 
the two tabs.  
 
For  access  and  servicing  the  recessed  grille  is 
opened by pulling these two tabs outwards.   
 
Note:  with  the  two  tabs  released  the  recessed 
grille frame will hinge downwards. With the grille 
hinged open caution should be taken.
