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).
12 Fan Speed Selection.
(refer also to wiring diagrams in Appendix 2)

T9901120-1-2 UK Page | 14
13.1 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.
13.2 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 must be cleaned regularly and the unit serviced at schedule intervals
– see Section 16: Service & Maintenance.
