7. INSTALLATION

The air curtain is designed to be recessed within ceiling voids or bulkheads with in 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.

Fig 1

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.

Fig 2

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.

Step 3 If you are installing model HX1500R or HX2000R, fit a 5th M10 threaded rod into the

hanging point in the middle of the unit. Refer to Appendix 1 and Fig 4.

Step 4 Secure each rod to a suitable structure that can support the weight of the unit (see

section 3: Specifications for weights).

WARNING: It is the sole responsibility of the installer to ensure that the fixing locations and

suspension system used are suitable for the air curtain being installed.

Step 5 Adjust the height of the unit on its hanging rods so the bottom surface of the casing goes

38mm up into the ceiling as shown in Fig 4. Ensure the unit is level.

7.3 Attaching the recessed grille to the air curtain

The recessed grille consists of:

 Metal frame
 Cellular discharge grille
 Hinged inlet grille

There are 4 fixing points on the HX1000R, 6 on the HX1500R
and 7 on the HX2000R (see Fig 5).

Fig 5 (HX2000R shown)

9901098-2-1 Page | 7

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 HX1000R unit
and three fasteners on HX1500R and HX2000R units.

Step 2 Make sure the grille will go the correct way around
(cellular discharge nearest to doorway). Offer the
recessed grille up through the cut-out in the ceiling
and attach it to the bottom of the air curtain casing
using M4 pozi head screws supplied. Start with
the screws shown in Fig 7 and then fit the two
at each end of the discharge grille.

Step 3 If fitting model HX1500R or HX2000R units insert 1 or
2 screws towards the middle of the unit as shown in
Fig 8.

Step 4 On model HX1500R or HX2000R units fit 1 screw in
the middle of the discharge grille. This screw is easier
to access if the hinged inlet grille is temporarily shut.

Step 5 With the hinged inlet grille open again adjust the

hanging rods (see Fig 9) so the grille frame fits neatly
against the ceiling. Ensure the grille frame is a snug fit
against the ceiling with no gaps all the way around.

NOTE: Open the hinged grille core to gain access to electrical connections, and for se rvicing and
maintenance.
