2 ELECTRICAL SAFETY

Electrical Supply and Wiring to the Air Curtain

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

 A 1 phase or 3 phase local isolator having a contact separation of at least 3mm on all poles

must be fitted in the electrical supply to the air curtain and located in an accessible position
adjacent to the unit.

 The appliance must be connected by cables having an appropriate heat resistant temperature

rating.

 All supply cables, circuit breakers and other electrical installation equipment must be correctly

sized for the air curtain model being installed; see section 3: Specifications.

 Models operating on a 3 phase electrical supply - see section 3: Specifications - require a

neutral connection (3N~).

 A 25mm size cable gland or conduit connector of IP21 rating or above should be used for the

Electrical Supply into the air curtain.

 See Wiring Diagrams for connecting electrical supply and control cables to the air curtain. The

air curtain must be earthed.

countries worldwide.

As with all our products, the T range of air curtains is designed with energy efficiency in mind.

T models suffixed E, W or A are designed to be surface mounted inside a building and located
horizontally over a doorway.

They must not be installed on the outside of a building or built into a cabinet or recessed in any way.

 Ladders
 Appropriate lifting equipment

7. INSTALLATION

The air curtain is designed to be located horizontally over a doorway. It must not be installed outside of
the building.

7.1 Location

Mount the air curtain above and as close to the doorway as
possible, with:

 the discharge grille not more than 3m above floor level
 at least 100mm clearance (air gap) above electric/water

heated air curtains, see Fig 1

Beware of doorway top edges, structural beams, door
opening/closure devices, etc., which may interfere with the air
stream and affect the location of the unit.

NOTE: For the air curtain to work well the width of the open doorway should be less than the length

‘A’ of the air curtain, see Appendix 1.

7.3 Ceiling Suspension

M10 threaded rods (not supplied) are used to suspend the
unit from the ceiling.

Suspend the unit from the ceiling as follows:

Step 1 Screw the threaded rods into all of the holes in the

top face of the unit as shown in Fig 3.

NOTE: Do not screw hanging rods too far in as they

Step 2 Fit M10 locking nuts (not provided) to prevent the

7.4 LPHW Models

For LPHW models ensure that water isolation valves are fitted in the flow and return pipework
adjacent to the air curtain and connected correctly as shown in the diagram in Appendix 1.

For the design of the water pipework system and pump, water flow rates and pressure drops for
maximum heat output of the air curtain are given in Table 2 below.

8. ACCESS TO ELECTRICAL CONNECTIONS

8.1 How to access terminals

To gain access to the air curtain for connection and commissioning, remove air inlet grilles and bottom
access panel as explained below.

First remove the plastic end caps at each end of the unit, if fitted, by pulling off to the side.

NOTE: All air curtain panels are protected in a plastic film. When access panels are removed this

8.1.1 Remove air inlet grilles

Using a Pozi No 1 screwdriver, remove each grill with its filter.

To remove, insert screwdriver into the elongated hole at the bottom
corner of the grille (see Fig 5) and turn the screw one quarter of a turn
anticlockwise.

8.1.2 Remove bottom access panel

Unfasten the securing screw at each end (see 1, Fig 6) and, if
applicable, two screws in the centre (T1500 and T2000 units only).

To remove, slide the access panel (see 2, Fig 6) out forwards.
