INSTALLATION OF THE AIR CURTAIN
The air curtain is designed to be surface mounted inside a building and located
horizontally over a doorway. It must not be installed on the outside of the building,
or built into a cabinet or recessed in anyway.
Location
The air curtain must be mounted so the discharge grille is
located up to 3.2m maximum above floor level and as
close to the doorway as possible. It must be installed level
or condensate may leak out if used for cooling. It is
recommended to leave a gap of 250mm minimum above
the air curtain to allow for pipework brazing operations.
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.
Wall Fixing
Bolt all of the wall brackets supplied to the rear face of the
unit as shown in the adjacent picture using the M10 bolts
supplied. Suitable wall fixing bolts (not supplied) need to
be used to fix the brackets to the wall, taking into account
the type of wall and the weight of the unit*, see table:

Step 1.
Refer to Figure 2, Page 11 for mounting details
and drill the fixing points in the wall.
Step 2.
Screw in the top wall bolts leaving a small gap between the head and the wall.
Lower the unit onto the bolts via the key-hole slots in the top of the wall brackets and then
screw in the bottom wall bolts.
Step 3
. Ensure all fixing bolts are tightened and the air curtain is safely secured to the
wall.
Ceiling Suspension
M10 threaded inserts are provided in the top face of the
unit (see Figure 2, Page 11 for positions) so it can be
suspended on M10 threaded hanging rods (not provided).
All suspension points must be used. Ensure each of the
hanging rods is secured onto a suitable structure that can
support the weight of the unit (see table above)
*
. Screw
the hanging rods into the inserts by a minimum or 20mm
and fit locking nuts (not provided) to prevent the rod
rotating and coming away from the casing. Do not screw
the hanging rod too far in or it could interfere with internal
components.
*
It is the sole responsibility of the installer to ensure that the building fixing locations and suspension system
used are suitable for the air curtain being installed.
