Assembly and operating instructions

General recommendations

Carefully read this instruction manual before installation 

and use of the AD unit. Keep these instructions in a safe 

place for future reference.

Application area

The Thermozone AD200W air curtains are intended 

for stationary/permanent installation above entrances 

and smaller doors with a height up to 2.5 meters, but 

can also be used for industrial heating and drying. 

The AD200W has been designed for connection to a 

low-pressure hot water supply. The unit can be surface 

mounted above a doorway or recessed into a ceiling.

Protection class: IP21

Operation 

The air is drawn in at the top of the unit and blown out at 

high velocity across the doorway, providing a protective 

air shield. The air shield minimises cold draughts and 

reduces heat loss through open doorways. For best 

eficiency, the air curtain(s) should cover the whole width 

of the opening.

The air director/grille is adjustable and is normally ang-

led outwards (5-10°) to achieve the best protection.

The airlow can be adjusted by use of the fan speed 

selector (CB30N)

The eficiency of the air curtain(s) depends on the air 

temperature and pressure differences across the door-

way and any wind pressure.

NOTE! Negative pressure in the building considerably 

reduces the eficiency of the air curtain. Ventilation 

should therefore be balanced.

Mounting 

The units may only be installed horizontally over a 

doorway with the air-stream directed downwards. For 

the protection of wider doorways, several units can be 

mounted next to each other.

For optimal performance it is recommended that a mini-

mum gap of 60mm is maintained above the air-curtain.

The units can be itted to the wall or suspended from the 

ceiling. Two or three (AD220W) mounting consoles are 

included with the air-curtain. 

The M6 bolts (2 or 3) which slot into the to the alumini-

um proile on top of the unit can slide sideways, allowing 

the consoles to be mounted at different distances from 

each other. (See details on page 2-3.)

Fitted on the wall

1.  Mount the consoles to the wall, see ig. A or B, page 

3 

2. Loosen the nuts on the upper side of the air curtain 

to be able to it the consoles between the nut and the 

unit.

3.  Mount the unit on to the consoles and tightened the 

nuts.

Mounting with suspension kit (extra)

When using the brackets for pendulum ixing ADPF1 

see ig. D on page 3 or ADPK1 see ig E on page 4.

Electrical installation

The air-curtain(s) should only be wired by a competent 

electrician, and in accordance with the latest edition of 

IEE wiring regulations.  

1  Remove the front plate by pressing a screwdriver or 

similar in to the two holes (Ø 5mm) underneath the 

edge of the front plate. Press until it clicks and the 

front plate can be openedand removed. See Fig. on 

page. 2

2. Remove the lid of the connection box by removing 

the four screws placed on the right side of the unit. 

Remove the knockouts on top of the unit for routing of 

electrical supply and remote switching cables  

Different combinations of fan speed and heat output 

are detailed in the wiring diagrams on pages 4-6.

Water connection

The air-curtain has an aluminium inned heating coil (in 

distance 2 mm) with copper tubes suitable for connec-

tion to a closed water heating system. 

The heating coil must not be connected to a mains pres-

sure water system or an open water system.

The water pipes (DN15 - 1/2" BSP-F, inside thread) 

are connected at the left hand side (when viewed from 

inside the building) on top of the unit. (See details on 

page 2)

The installation should be carried out by a certiied 

installer.

NOTE: Care must be taken when connecting the pipes. 

Use a wrench or similar to hold the air-curtain connec-

tions to prevent straining of the pipes and subsequent 

water leakage during connection to water supply pipe-

work.

A bleed valve should be connected at a high point in the 

pipe system and all air bled during commissioning of the 

air-curtain. 

It is also recommended that a drain valve is itted in 

the supply pipe-work. This should be mounted on the 

outside of the AD unit. 

Air-vent and drain valves are not 

included in the heating coil.

Filter

The heating coil is protected by an air ilter which covers 

the coil face.

Mounting in false ceiling
