Thermozone AD 200 A/E

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 AD200 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 unit
can be surface mounted above a doorway or recessed
into a ceiling.
Protection class: AD200A, AD200E 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 (See accessories)

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 (AD220) 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 3.)

Fitted on the wall or beam

1. Mount the consoles to the wall/beam, see ig. A

or B, page 3 (AD220E see page 4-5)

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 tighte–

ned the nuts.

Suspended from the ceiling

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

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

unit.

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

nuts.

Alternative mounting

When using the brackets for pendulum ixing ADPF1 or

suspension set ADPK1 see ig. D or 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 ig. on page. 3

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 (2xØ23mm, 2xØ29mm) 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 6-9.
The cable-glands used must guarantee the protection

class requirements!

For the units with electrical heating, the power and
voltage can be supplied in different connection areas
(see wiring diagram).
In the distribution board it is to be indicated that

”the air

curtains can be supplied from more than one connec

tion”.
