General instructions

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

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

Application area

The SF air curtain unit is intended for 
installation in revolving doors. 

SF is installed to the side of the entrance.

Operation

Air is drawn in at the side of the unit and 
blown out towards the entrance so that it 
shields the door opening and minimizes heat 
loss. To achieve the optimum curtain effect 
the unit must extend the full height of the 
door opening. 

The grille for directing exhaust air is 

adjustable and is normally angled towards the 
curved doorway to achieve the best protection 
against incoming cold air.  

The airflow can be adjusted by use of the fan 

speed selector. 

The efficiency of the air curtain(s) 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!

Installation 

The unit is installed as floor standing on 
adjustable feet that make it possible to 
compensate for possible irregularities in the 
floor. The feet are bolted to the floor and 
covered by a covering edge. SF is mounted 
to the left of the door seen from inside the 
building and should also be secured to the 
door. SF has a curved design that integrates 
neatly with the door. Extension is possible up 
to 3900 mm (extension without fans).

Ensure that the service hatch is accessible 

and can be fully opened.

See sketches p.2-3.

Electrical installation

Electrical connection may only be carried 
out by an authorized electrician, and in 
accordance with these instructions and the 
applicable regulations.

1. The service hatch is opened by slackening 

off the screws in the side of the unit.

2. The unit is connected via one of the cable 

glands in the upper or lower side of the 
unit. 

  
Different combinations for controlling fan 
speed and heat output are available. See 
wiring diagram (p.5). Connections are made 
using EKK, EKLK or corresponding type 
cables. The cable glands used must meet the 
protection class requirements. For units with 
electrical heating, the power and control 
voltage can be supplied separately. It must be 
indicated in the distribution board that ”The 
air curtains are supplied from more than one 
connection”.

Start up

Note! When using for the first time or when 
starting up after a long period of disuse, a 
small amount of smoke and a slight odour 
may occur temporarily, which is completely 
normal.

Basic setting fan speed

The fan speed is set using the speed control.

Note that the air flow direction and speed 
may need fine adjustment depending on the 
loading of the door.
