Electrical Supply
Electrical supply is 240V single phase.
It is recommended that the electrical supply to the base unit is via an
appropriate switched isolator in accordance with the relevant regulations
and must be via a fused isolator having a contact separation of greater
than 3mm on all poles.
All units must be wired in accordance with IEE regulations for the Electrical
Equipment of Buildings and the installer should ensure that a suitable
isolating switch is connected in the mains supply.
Before Installation
Mounting location
It is recommended that the air curtain
is installed on the inside of the
building. The units should be installed
horizontally directly over the door
opening or within the ceiling void or
roof space.
Care must be taken to allow complete
free air movement into the inlet grilles
of the unit to ensure correct working
operation of the air curtain. The
discharge opening should be as close
to the top of the door as possible and to
cover the entire door width.
Units can be mounted adjacent to each
other to cover the full door opening
across wider entrances.
