INSTALLATION OF THE HEAT PUMP AIR CURTAIN
The air curtain has been designed to be surface mounted inside of the building and
located horizontally over a doorway. It must not be installed outside of the building,
or built into a cabinet or recessed in anyway. The air curtain is intended for use as a
heating only unit.
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.
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 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 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 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 or 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 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.
