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 3m 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 Depending on whether a standard or wider width
recessed grille is used, cut an aperture in the ceiling
to the dimensions in Appendices 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 fixing brackets to secure hanging rods.
An additional threaded rod is fitted on a 1.5m unit with
two extra threaded rods fitted on a 2m unit, see
Appendices 1.
:
NOTE Do not let the hanging rods come below the bottom
of the unit casing or they may prevent the recessed
grille fitting properly.
