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).

T9901008-1-1 UK (v9) Page | 15

16.1 Verify system operation

To commission the system, verify the followin g 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 customer and hand over

Before leaving site, hand over the installation to the customer/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 understand 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.

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:

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 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 circuitry of the Ecopower PCB

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)

18. FAULT CONDITIONS

T9901008-1-1 UK (v9) Page | 17

19.1 Every week

Turn off the air curtain to prevent entry of dust then clean the face of the air inlet grilles and air filters
inside the grilles using a vacuum cleaner with an extension tube and brush.

19.2 Every 3 months

Clean and inspect the inside of the air curtain as follows:

Step 1 Remove plastic end caps at each end of the unit by pulling off to the side.

Step 2 Use a Pozi No.1 screwdriver to remove air inlet grilles by releasing the fasteners at the

bottom corners of each air inlet grille. See Fig 5, Section 8.1.1.
