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 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.
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.
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.
7. INSTALLATION
NOTE: For the air curtain to work well the doorway should be less than the width of the airstream.
Fig 1
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.
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.
Fig 3

9901098-2-1 Page | 7
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).
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 4
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.
Fig 5 (HX2000R shown)

9901098-2-1 Page | 8
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.

10.1 BMS remote on/off
To enable the system to be used with BMS remote
switching, an INHIBIT two way screw terminal is fitted on
the air curtain motherboard (see 2, Fig 12).
To allow the unit to run, use 2 wires to link the terminal to a
remote volt free contact.
To switch the unit off, leave terminals disconnected (open
circuit).
In a master/slave arrangement consisting of several air curtains, connect the remote contact to any
one of the air curtains. All units will then turn on and off.
At factory setting a wire link is fitted to the INHIBIT terminal (see 3, Fig 12). For summer operation
connect a 3.3kΩresistance across the INHIBIT terminal and only the fans will run, without heat, even
if the remote controller is calling for heat.
10.2 Overheat cut-out indication
The air curtain motherboard includes a HEALTHY two way screw terminal (see 1, Fig 12) to provide a
fault signal indication if the electric heater overheat cut-out operates (electric heated air curtains only).
A healthy system provides a 24V DC signal at the terminals. An overheat cut-out fault will be 0V DC
at the terminals.
10.3 Weather compensation
For Weather Compensation Heat Control, fit an outside air temperature sensor (Specification - 10k
NTC sensing element, time constant 14 minutes and IP54 protection, or optional Siemens QAC2030).
Use a 2-core cable to connect the outdoor air temperature sensor to air curtain terminals 1 and 2 on
the connector terminal block on electric heated units (see wiring diagrams, Appendix 2A, 2B, 2C), or
terminals 5 and 6 on water heated units (see wiring diagram, Appendix 2D).
Set DIP switches 2 and 4 to the ON position on the Ecopower motherboard (see section 11: System
Configuration). For Master/Slave multiple installations, this must be the Thermostat Master unit.
10. EXTERNAL CONTROLS

Sound pressure levels dB(A) at 3m distance are for a single air curtain mounted at its maximum mounting height, operating in a
room with average acoustic characteristics as defined in CIBSE Guide B5 (reverberation time 0.7s at 1kHz) and a room size
equivalent to 8 air changes per hour (ac/h). Care needs to be taken when selecting air curtains for an installation as noise levels
can be several dB higher if the mounting height is reduced, if the room is more ‘live’ (i.e. hard surfaces, no furnishings or
absorbent materials), if the room is smaller than 8 ac/h equivalent or a combination of these factors. Noise levels will also increase
if more than one air curtain is installed at the same doorway (e.g. +3dB(A) for 2 equal point sources: direct field).

15.1 Verify system operation
To commission the system, verify the following conditions are met:
All fans are working.
Fans operate at Low, Medium and High speeds.
There is no excessive mechanical noise coming from the fans.
When heating is selected, the air stream from the discharge grille warms up across the whole
length of the air curtain.
When set to manual with fans set to high speed, heating increases as higher heat is selected.
Warm air reaches across the doorway with door open or closed.
Ecopower remote controller operates correctly in both manual and auto modes.
15.2 Instruct operator and hand over
Before leaving site, hand over the installation to the end user or their representative.
Recommend that any person operating the air curtain be given adequate instruction and supervision
by a person responsible for their safety. Children and those with reduced physical, sensory or mental
capabilities should not operate the air curtain.
Recommend that the doorway should be closed whenever possible.
Recommend that during times of high pedestrian use it will become an ‘open doorway’. The air
curtain then serves an essential purpose by saving energy and providing comfort to occupants.
Explain that the inlet grilles and air filters (if fitted) must be cleaned regularly and the unit serviced at
schedule intervals – see section 18: Service & Maintenance.

17.1 Thermal cut-out
An overheat fault in electric heated units may cause the thermal cut-out trip(s) to operate.
This is indicated by flashing LEDs on the remote control and a red status LED on the air curtain
motherboard.
Before resetting ensure there is adequate air flow from the air curtain and the unit has been
commissioned as per section 15.
To reset a thermal cut-out trip:
Step 1 Switch off the electrical supply to the air curtain.
Step 2 Allow time for the air curtain to cool down, typically 10 minutes.
Step 3 Switch on the electrical supply to the air curtain.
Step 4 Press the Auto button on the remote control 4 times.
Air curtain heaters will then operate and after 30 seconds the LEDs on the remote control will stop
flashing and the status LED will flash green.
17.2 Fuses
In the event of an electrical fault internal electrical fuses may operate.
There are two internal fuses located on the motherboard inside the air curtain:
Fuse 6.3A (T) supplies the fan motors within the air curtain
Fuse 125mA (F) controls the operation of the motherboard
17.3 PCB status indication
LED1 on the air curtain motherboard is a status LED (See LED1 on Appendices, Wiring Diagrams).
This indicates the status of the Ecopower Control system as follows:
1. LED flashing green – operation normal
2. LED flashing red – low supply voltage or controller not plugged into motherboard
3. LED permanently red – thermal cut-outs open circuit from an overheat situation (see
Section 17, Fault Conditions for how to reset)
4. LED flashing alternate red/green – air curtain configured for Weather Compensation
Control (DIP 2 and 4 ON) but no outdoor air sensor is connected to Ecopower PCB.
