INSTALLATION OF YOUR HORIZONTAL APPLICATION C AIR-CURTAIN

The C air curtain has been designed for surface mounting only inside of
the building.

Location

Ensure that the unit is mounted within its height
specification of 1.8m minimum to 3.0m maximum
(from floor level to the underside of the unit) and
that it is situated as close to the door as possible
with a 100mm air gap above the air curtain (see
adjacent figure). In some cases it may not be
possible to mount the air curtain as close to the
door as possible as the air stream may strike the
top edge of the doorway, a structural beam or a
door opening device etc, therefore this will have
to be taken into account when locating the unit.

Wall Fixing

Bolt the wall brackets to the rear face of the unit
as shown in the adjacent figure (using the bolts
supplied). Before fitting the unit to the wall obtain
suitable fixing bolts, taking into account wall type
and unit weight (see table 1).

Step 1. Refer to Figure 1 for mounting details

and drill the wall accordingly.

Step 2. Screw in the top bolts leaving a small

gap between the head and the wall; lower the
unit onto the bolts via key hole slots in the top of
the wall brackets and then screw in the bottom
bolts.

Step 3. Ensure all fixing bolts are tightened to

stop the unit being lifted off the wall.

Ceiling Suspension

6mm threaded inserts are provided in the top
face of the casing (4 x M6 on the 1m and 6 x M6
on the 1.5/2m models, for dimensions see Figure

1) allowing the unit to be suspended on threaded
rod (threaded rod is not provided). Ensure each
of the threaded rods are secured on to a suitable
structure that can support the weight of the unit
(for unit weights see Table 1)*. When fitting the
threaded rod ensure that it does not interfere with
internal components. Fit locking nuts (not
supplied) and ensure they are engaged by a
minimum of 20mm to stop the threaded rod
rotating and coming away from the casing.

*Please note it is the sole responsibility of the installer to ensure that the fixing points
and bolts used are suitable for the air curtain being installed.

Safety and Electrical Connections

All electrical wiring and connections MUST be carried out by a competent qualified
electrician in accordance with the latest edition of the IEE wiring regulations and/or
local statutory regulations.

A single phase or 3 phase local isolator with a contact separation of at least 3mm in all

poles must be fitted to the supply wiring (the isolator must be fitted in an accessible
position).

The air curtain must be earthed.

The appliance must be connected by means of wires having an appropriate

temperature rating (heat resistant) (electric models only).

Ensure that the supply cables, circuit breakers and other electrical installation

equipment are correctly sized for the air curtain being installed; see Table 1 for Power
Ratings. See also data badge on the left hand side of unit under end cap.

On a 3 phase electrical supply the unit requires a neutral connection (3N~).

Cable glands used for the Electrical Input must be rated IP21 or higher.

To gain access to the electrical

connections the air intake grilles must
be removed. Ensure electrical mains
supply to the unit is isolated. If end
caps are already fitted, remove them
from the air curtain first (see insert).

Two air inlet grilles are fitted on 1m,

three on 1.5m and four on 2.0m
models.

Remove intake grilles by unfastening

two screws on each grille; M4 x 10mm
Pozi No.2 screws accessed via larger
hole in the bottom of the grille (see
adjacent figure).

Optional filter fits inside
