INSTALLATION

The air curtain is designed to be recessed within ceiling voids or bulkheads within a building and
located horizontally over a doorway. It must not be installed outside of the building.
7.1 Location
Mount the air curtain above and as close to the doorway as
possible, with:

the recessed grille not more than 3.5m above floor
level

the air discharge (see 1, Fig 1) section of the
recessed grille nearest the doorway and the air inlet
section (see 2, Fig 1) furthest from the doorway
Beware of doorway top edges, structural beams, door
opening/closure devices, etc., which may interfere with
the air stream and affect the location of the unit.
NOTE: For the air curtain to work well the doorway should be less than the width of the airstream.
7.2 Ceiling Suspension
Step 1 Cut an aperture in the ceiling to the dimensions
in Appendix 1. Cut notches, if necessary, to clear
screws in the air curtain casing.
:
NOTE For LPHW models, pipework will need to be
installed above the curtain. Allow sufficient access and
height clearance within the ceiling void to do this.
Step 2 Fix M10 threaded rods (not supplied) through
the 2 holes at each end in the top casing
(see Fig 2). Feed the rods through the casing and
attach to fixing brackets near the bottom of the
unit (see Fig 3, looking up into the air curtain). Use
M10 lock-nuts either side of the fixing bracket to
secure the hanging rod.
:
NOTE Do not let these four hanging rods come below
the bottom of the unit casing or they may prevent the
recessed grille fitting properly.
