8.1 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 ceil-
ing.
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 must cover the entire
door width.
Units can be mounted adjacent to each other to
cover the full door opening across wider entranc-
es.
8.2 Electrical Supply
These units are suitable for connection to a 415
Volt, 50Hz 3 phase and neutral supply for electrical-
ly heated 8-24kW models.
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 safety reasons, a sound earth connection must
be made to the unit. The unit should be wired in
accordance with IEE Regulations for the Electrical
Equipment of Buildings.
8. Installation Details
8.3 Installation
It is the sole responsibility of the installer to ensure
that the points of attachment to the building are
sound. Consultation with the consultant/architect or
owner of the building is recommended to ensure
that a sound, mechanically stable installation is
achieved.
All attachments must be capable of supporting the
weight of the product .
Step 1
Disassemble the heater following section 7.
Step 2
Either drop rods or catenary wire can be used to
fasten the air curtain to the ceiling support structure.
The mounting points can be seen in section 3.
Step 3
The height between the ceiling face and the edge
of the air curtain case needs to be adjusted to 3-10
mm to enable the grille assembly to fit flush against
the ceiling. Adjust accordingly.
Step 4
Refit grille assembly and panels following section 7.
Ensure the grille sits flush against the ceiling.
8.4 Installation - Wiring
With hatches open, connect the electrical supply
and controller interconnecting wiring to the appro-
priate terminals on the controller base unit (See rele-
vant wiring diagram section 4).
