INSTALLATION OF THE HEAT PUMP AIR CURTAIN
The air curtain is designed to be surface mounted inside of the building and located
over a doorway. It must not be installed outside of the building, or built into a
cabinet or recessed in any way.
Location
The air curtain must be mounted so the discharge grille is
between 1.8m minimum and 3.75m maximum above floor
level and situated as close to the doorway as possible.
Beware of doorway top edges, structural beams, door
opening devices, etc. which may interfere with the air
stream and affect the location of the unit. The air curtain
must be installed level or condensate may leak out,
particularly if it tilts down at the left hand side (looking out
of the doorway from inside). It is better to tilt down slightly
at the right hand side as the drain tray spout is this side.
Wall Fixing
Bolt all of the wall brackets supplied to the rear face of the unit as shown in the adjacent
picture using the M6 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 1 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 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 1 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 of 20mm and fit
locking nuts (not supplied) to prevent the rod rotating and
coming away from the casing. Do not screw the hanging
rod too far in or it will 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.
