General Instructions

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

The guarantee is only valid if the units 
are used in the manner intended by the 
manufacturer and in accordance with the 
Frico mounting and operating instructions.

Are of use

The Frico Thermozone AC 500 is an air 
curtain intended to be installed above 
industrial- and warehouse doors of 3,0 —6,0 
meters height. The air curtains eficiency is 
depending on the load of the door. 

Protection class IP24.

Function

The air intake is positioned at the top of the 
unit and blown with high velocity through a 
honeycomb lattice which results in a strong 
and laminar air stream. The air curtain 
consists of 2 or 3 powerful diagonal fans 
which are mounted in an air stream channel. 
The housing is made of galvanised steel 
covered with grey enamel. The air stream 
protects the opening and minimises hot/cold 
leakage through the open door. Insects, dust 
and exhaust fumes are also prevented from 
entering the building. The delectors that 
are itted on both sides of the outlet can be 
used to direct the air stream up to ±15°. It 
is always better to tilt the complete unit if 
possible. The airlow will be controlled by a 
fan regulator, placed in a separate box.

NB! under-pressure in the building will 

signiicantly reduce the effectiveness of the 
air curtain. Ventilation ought to be balanced.

Mounting

Thermozone air curtains are in general 
mounted on the inside of the door and as 
close to the opening as possible. When they 
are supposed to protect a cold store they 
should be mounted on the warm side of the 
opening. To cover the entire opening the units 
must be placed as close as possible to each 
other. If possible tilt the units towards the 
opening.

Instruction for installation and use

Suspension brackets are included, with 

which the air curtain can be hung from 
overhead beams / ceiling or with which they 
can be screwed to the wall.

A) Mounting on overhead beams or in the  
  ceiling

1. A heavy-duty beam is to be mounted in a    
suitable position above and along the door opening. 
The air curtains can also be mounted to the ceiling, 
however it may then be dificulties to access the 
connection box.
2. Fit the suspension brackets on the ends of the  
air curtain. (Fig 1.)
3. Check the c-c distance between the suspension  
bracket’s ixing holes. Measure and drill holes  
(for 10 mm bolts) in the appropriate positions on 
the beam/ceiling
4. Lift up the air curtains one by one and bolt in  
position. Tilt the unit outwards against the door  
and tighten the screws. (Fig 2.)
5. Mount the fan regulator in an appropriate place  
on the wall.
6. Carry out the electrical connection.

B) Mounting against a wall

1. Fit the suspension brackets on the rear side 

of the air curtain. (ig 3).

2. Check the c-c distance between the 

suspension  bracket’s ixing holes. Measure 
and drill holes (for 10 mm bolts) in the 
appropriate positions on the wall.

3. Lift up the air curtains one by one and 

hang the key holes of the brackets on the 
bolts. Secure using 6 mm screws so that the 
units cannot be unhooked again. Tilt the 
unit outwards against the door and tighten 
the bolts.

4. Mount the fan regulator in an appropriate 

place on the wall.

5. Carry out the electrical connection.

Electrical installation

The electrical installation must be carried 
out according to existing regulations and by 
an authorised electrician. The unit must be 
preceded by an all-pole switch. There are 
many different ways to regulate the fan speed.
