Fix the grille as follows:
Step 1 Open the hinged inlet grille using a flat bladed
screwdriver to release the quarter turn fasteners
(see Fig 6). There are two fasteners on the
T1000R unit and three fasteners on T1500R and
T2000R units. Before lifting the grille frame into
position, remove four (six on T1500R/T2000R)
M6 bolts fitted on the inside edge of air curtain.
Step 2 Make sure the grille will go the correct way
around (discharge nearest to doorway). Offer
the recessed grille up through the cut-out in
the ceiling.
Step 3 Using the M6 bolts removed in Step 1, secure
grille by fixing each bolt through the slotted
brackets as shown in Fig 8. For illustration
purposes Fig 8 details a wider recess grille.
With the hinged grille open, adjust the height of
the grille frame via slots in each bracket, so
frame is snug fit against the ceiling with no
gaps all the way around.
Step 4 To stop discharge air re-circulating within the
air curtain a sliding separator will need
adjusting up or down (see Fig 9). To adjust
plate release M6 bolts either end, extend the
slide plate so that it will touch the topside of
the grille along its whole length and tighten the
bolts. It will be necessary to close the hinged
grille core to gauge where the separator plate
should be fitted.
Step 5 Once the above steps are complete the
hinged grille core can be closed and all the
quarter turn fasteners tightened up.
NOTE: Open the hinged grille core to gain access to
electrical connections, and for servicing and
maintenance.
