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
efficiency, 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 airflow can be adjusted by use of the fan speed
selector (See accessories)
The efficiency 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 efficiency 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 fitted 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 profile 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 fig. 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 fit 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

2. Mount the unit on to the consoles and tightened the
nuts.
Alternative mounting
When using the brackets for pendulum fixing ADPF1 or
suspension set ADPK1 see fig. 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 fig. 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".
