Application
The Thermozone AD Corinte W air curtain
is supplied with a water coil and is intended
for permanent installation above or beside
entrance doors and other openings up to
three metres in height/width. Protection class:
IP20.
Operation
Air is drawn in at the top/rear of the unit and
blown out downwards/outwards so that it
shields the door opening and minimizes heat
loss. To get the best curtain effect the unit
must cover the full height/width of the door
opening.
During installation the exhaust grille is
normally rotated outwards slightly so that
the airflow obstructs incoming cold air, (see
Fig. 1).
The fan speed should be controlled using a
frequency converter.
The effectiveness of the curtain depends on
the load on the entrance in question. Note
that negative pressure in the premises will
reduce the effectiveness of the air curtain
considerably. The ventilation should therefore
be balanced.
Vertical mounting
The unit is mounted vertically on the floor
with the exhaust opening facing outwards.
Before installation, decide whether any
electrical connections or water connections
are to be made from below.
Leave the protective plastic in place during
installation. Take care to avoid damaging the
surfaces. For installation see Figure 4.
1. Undo the screws in the front panel.
2. Undo the screws that secure the front panel
to the exhaust grille.
3–4. Take off the front panel.
5. Place the edging on the floor and if
necessary secure it with bolts or similar in
the countersunk holes (see Fig. 8). Stand
the air curtain on the edging.
6. A flat bar is included for securing the air
curtain. Fixate the air curtain through the
square-shaped hole. Make sure that the flat
bar is not bent when fixing.

Mounting and operating instructions
7. Secure the top with an angle bracket or
similar to prevent the air curtain from
toppling over. There is a hole in the centre
of the top of the air curtain with an internal
M6 thread for securing the bracket.
To remove dirt and finger prints, polish the
panels with a suitable cleanser. Any print
that may be on the panels is removed with a
suitable solvent.
Horizontal mounting
The unit is mounted horizontally with the
outlet facing downwards. Do not remove
the protecting plastic until mounting is
completed. Be careful so the surfaces are not
damaged.
Mounting less than 180 mm from the ceiling
is not recommended since it will reduce the
flow through the unit.
Two brackets are delivered with the unit
for mounting on the wall or hanging from the
ceiling.
Horizontal mounting on the wall
1. Mount the brackets on the wall according to
measures in Fig. 6a and 6b.
