Inlet foam filter replacement GR 

Figure 28 GR inlet foam retaining clip 1

1.  To remove the filter element of the GR 

units, select the clip from either end of the 
panel, push the outside leg of the retaining 
clip towards the centre of the filter/inlet 
grille which will release the clip out of 
the inlet grille frame, work along the clip 
releasing until the clip is fully out of the 
frame.

2.  The filter element can now be removed 

and replaced with a new element reverse 
the procedure to refit and re-secure

Honeycomb outlet replacement 

To remove the honeycomb outlet, first remove 
the complete carrier. The carrier is secured at 
one end by a bolt and stud to the other end. 
Remove the end panel to access this fixing bolt 
and then release the carrier from the stud side, 
on the 2m models the centre support can be 
moved to one side to allow the stud side to be 
released 

On the GS units peal back the tabs which 
retain the honeycomb outlet, remove the 
honeycomb media from the carrier and 
replace. Then fit the new honeycomb media 
into the carrier and push the tabs back over 
the honeycomb to secure 

Figure 29 GS honeycomb retaining

On the GR units the tabs are part of a 
retaining plate, peal back the tabs which retain 
the honeycomb outlet remove the media 
from the carrier and replace. Then fit the new 
honeycomb media into the carrier and push 
the tabs back over the honeycomb to secure

Note the position of the temperature sensor 
from the right of the unit and ensure it does 
not get damaged, the cables will need to be 
disconnected from the control panel terminals
