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 recesse d grille not more than 3m 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.
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 Depending on whether a standard or wider width
recessed grille is used, cut an aperture in the ceiling
to the dimensions in Appendices 1. Cut notches, if
necessary, to clear screws in the air curtain casing.
NOTE: For LPHW models, pipework will need to be installed
Step 2 Fix M10 threaded rods (not supplied) through the 2
NOTE: Do not let the hanging rods come below the bottom
above the curtain. Allow sufficient access and height
clearance within the ceiling void to do this.
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 fixing brackets to secure hanging rods.
An additional threaded rod is fitted on a 1.5m unit with
two extra threaded rods fitted on a 2m unit, see
Appendices 1.

and 6th threaded rods, see Appendices 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 hangi ng rods so the bottom surface of the casing goes
between 25-50mm up into the ceiling as shown in Fig 4. Ensure the unit is level.
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.
7.3 Attaching the recessed grille to the air curtain
The recessed grille consists of:
Metal frame
Hinged standard or wider width inlet/discharge grille
Slotted fixing brackets
There are 4 fixing slotted brackets on the T1000R with 6 brackets fitted on T1500R and T2000R (see
Fig 5a and Fig 5b).

T9901012-1-1 UK (v9) Page | 7
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
T1000R unit and three fasteners on T1500R and
T2000R units. Before lifting the grille frame into
position, remove four (six on T1500R/T2000R)
M6 bolts fitted on the inside edge of air curtain.
Step 2 Make sure the grille will go the correct way
around (discharge nearest to doorway). Offer
the recessed grille up through the cut-out in
the ceiling.
Step 3 Using the M6 bolts removed in Step 1, secure
grille by fixing each bolt through the slotted
brackets as shown in Fig 8. For illustration
purposes Fig 8 details a wider recess grille.
With the hinged grille open, adjust the height of
the grille frame via slots in each bracket, so
frame is snug fit against the ceiling with no
gaps all the way around.
Step 4 To stop discharge air re-circulating within the
air curtain a sliding separator will need
adjusting up or down (see Fig 9). To adjust
plate release M6 bolts either end, extend the
slide plate so that it will touch the topside of
the grille along its whole length and tighten the
bolts. It will be necessary to close the hinged
grille core to gauge where the separator plate
should be fitted.
Step 5 Once the above steps are complete the
hinged grille core can be closed and all the
quarter turn fasteners tightened up.

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).

16. COMMISSIONING THE SYSTEM
16.1 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 Control operates correctly in both manual and auto modes.
16.2 Instruct operator and hand over
Before leaving site, hand over the installation to the end user or their representative.
Explain that any person operating the air curtain must be given supervision and instruction by the
person responsible for their safety, concerning the safe use of the unit and to understa nd any hazards
involved. 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 but 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 19: Service & Maintenance.
NOTE: Leave these instructions with the customer/end user or their representative!!

18. FAULT CONDITIONS
18.1 Overheat safety cut-out
An overheat fault in electric heated units may cause the overheat safety cut-out(s) to operate.
This is indicated by flashing LEDs on the remote control and a red status LED on the Ecopower PCB
inside the air curtain.
Before resetting ensure there is adequate air flow from the air curtain and the unit has been
commissioned as per Section 16.
To reset a overheat safety cut-out trip:
Step 1 Switch off the electrical supply to the air curtai n.
Step 2 Allow time for the air curtain to cool down; typically 10 minutes.
Step 3 Switch on the electri cal sup ply to the air curtain.
Step 4 Press the Auto button on the Ecopower 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 on the Ecopower PCB in the air curtain will flash green.
18.2 Fuses
In the event of an electrical fault internal electrical fuses may operate.
There are two internal fuses located on the Ecopower PCB inside the air curtain:
Fuse 6.3A (T) supplies the fan motors within the air curtain
Fuse 100mA (F) controls the operation of the motherboard
18.3 Ecopower PCB status indication
There is a status LED on the Ecopower PCB inside the air curtain (See LED shown on Wiring
Diagrams in the Appendix).
This indicates the status of the Ecopower Control system as follows:
1. LED flashing green – operation normal
2. LED flashing red – low supply voltage, remote control not plugged in or RJ cable fault
3. LED permanently red – overheat safety cut-out(s) open circuit from an overheat situation
(see Section 18, Fault Conditions for how to reset)
