Assembly and operating instructions

General Instructions

Read these instructions carefully before 
installation and use. Keep this manual for 
future reference.

The product may only be used as set out in 
the assembly and operating instructions. The 
guarantee is only valid if the product is used 
in the manner intended and in accordance 
with the instructions.

Application area

The Thermozone AR3500 air curtain unit 
is supplied without heating, with electrical 
heating or hot water heating

PA3500 is intended for entrances and 

smaller doors up to 3.5 metres in height.

PA4200 is intended for larger door ways and 

industrial door up to 4,2 metres in height.

Protection class for units with electrical 
heating: IP20. 
Protection class for units without heating and 
units with water heating: IP21. 

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 achieve the optimum curtain effect 
the unit must extend the full height/width of 
the door opening.

The grille for directing exhaust air is 

adjustable and is normally angled outwards to 
achieve the best protection against incoming 
cold air.

The efficiency of the air curtain depends 

on the air temperature, pressure differences 
across the doorway and any wind pressure.

NOTE! Negative pressure in the building 
considerably reduces the efficiency of the air 
curtain. The ventilation should therefore be 
balanced.

Mounting

The air curtain range includes possiblities 
for horizontal installation and for vertical 
installation and the units can also be installed 
recessed into suspended ceilings.

Horizontal mounting

The air curtain unit is installed horizontally 
with the supply air grille facing downwards 
as close to the door as possible. Minimum 
distance from outlet to floor for electrically 
heated units is 1800 mm. For other minimum 
distances, see fig. 3.

For the protection of wider openings, several 

units can be mounted next to each other 
using a joining kit (fig. 8). 

A design kit for a neat installation that 

conceals cables, pipes and mountings 
is available for both wall and ceiling 
installations, se accessories pages.
