6.1 Mounting
All units should be installed horizontally directly
over the door opening. It is recommended that the
air curtain is installed on the inside of the building,
within the open room space against a wall or
ceiling.
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.
These units are designed for surface mounting
and should not be placed into a ceiling void, due
to possible obstruction of airflow and difficulty in
routine cleaning and maintenance.
6.2 Electrical Supply
These units are suitable for connection to a 415
Volt, 50Hz 3 phase and neutral supply.
Electrically heated models consume 18kW &
24kW at 415 volts when switched to the full heat
position depending on their model and capacity
size.
The appliance shall be connected to the supply
via an appropriate switched fused double pole
isolator having a contact separation of greater
than 3mm. Test for correct operation and refit the
cover.
For connection to the mains supply it will be
necessary to remove the outer cover from the unit.
After removing the cover you will note the mains
terminal block and it will be necessary to connect
the mains supply and the lead from the remote
switch box prior to refitting the cover. Wire in
accordance to diagrams in section 4.1 to 4.3.
For safety reasons, a sound earth connection
must always be made to the unit before it is put to
use. The unit should be wired in accordance
with IEE Regulations for the Electrical Equip-
ment of Buildings.
6. Installation Details
6.3 Installation
It is the sole responsibility of the installer to ensure

weight of the product detailed in Section 3.
